How prevalence estimates will be aff ected by the newcriteria and how autism spectrum disorder will relate tothe newly created social (pragmatic) communicationdisorder (defined by substantial diffi culties with socialuses of both verbal and non-verbal communication butotherwise not meeting criteria for autism spectrumdisorder) remain to be assessed

Autism could potentially be subgrouped at clinical (egby developmental pattern or trajectory and comorbidity)cognitive and aetiological levels (eg by genetic andenvironmental correlates)6 Although the term autismspectrum disorder is frequently used the term autismspectrum condition also signals a biomedical diagnosisfor which individuals need support and recognises areasin which aff ected individuals are diff erent from thosewithout autism but without the negative overtones of the

disorder label

EpidemiologyPrevalenceThe prevalence of autism has been steadily increasingsince the first epidemiological study7 which showed that4middot1 of every 10 000 individuals in the UK had autism Theincrease is probably partly a result of changes in diag-nostic concepts and criteria8 However the prevalencehas continued to rise in the past two decades particularly

in individuals without intellectual disability despite

Early signs and screeningEarly identification allows early intervention Previouslychildren with autism were often identified when olderthan 3ndash4 years but toddlers are now frequently diag-

nosed because atypical development is recognised earlyEarly indicators are deficits or delays in the emergence ofjoint attention (ie shared focus on an object) and pretendplay atypical implicit perspective taking deficits inreciprocal aff ective behaviour decreased response to ownname decreased imitation delayed verbal and non-verbal communication motor delay unusually repetitivebehaviours atypical visuomotor exploration inflexibilityin disengaging visual attention and extreme variation intemperament7879 These indicators contribute to screen-ing and diagnostic instruments for toddlers79 How-ever identification of high-functioning individuals is stilloften later than it should be80 particularly for females2324

Variability in age cognitive ability and sex leads todiff erential presentation and the need for appropriatescreening instruments (table 3) Care should be takenduring selection of screening instruments (and the cutoff for further action) because the target sample and purposeof screening vary81 Routine early screening at ages 18 and

Clinical assessmentDiagnostic assessment should be multidisciplinary anduse a developmental framework of an interview with theparent or caregiver interaction with the individualcollection of information about behaviour in communitysettings (eg school reports and job performance)cognitive assessments and a medical examination92 Co-

occurring conditions should be carefully screenedThe interview of the parent or caregiver should cover

the gestational birth developmental and health historyand family medical and psychiatric history It shouldhave specific foci the development of social emotionallanguage and communication cognitive motor and self-help skills the sensory profile and unusual behavioursand interests Behavioural presentation across diff erentcontexts should be investigated Ideally a standardisedstructured interview should be incorporated into theassessment process (table 3) Adaptive skills should bechecked with standardised instruments (eg Vinelandadaptive behaviour scales) In children parentndashchildinteraction and parent coping strategies should bespecifically investigated because they are relevant for theplanning of interventions

Interviews with the individual should be interactiveand engaging to enable assessment of social-communi-cation characteristics in both structured and unstructured

Although many (high-functioning) individuals withautism achieve some degree of explicit or controlledmentalising101 the implicit automatic and intuitivecomponents are still impaired even in adulthood102 Early-onset mentalising diffi culties seem to be specific toautism but late-onset deficits are reported in disorderssuch as schizophrenia103 Mentalising is closely entwined

with executive control and language104 so that thedichotomous view of social versus non-social cognition ispotentially misleading in autism

Historically the domain of mentalising has beenlargely centred on others but self-referential cognitionand its neural substrates are also atypical in autism105106 Therefore deficits in the social domain are not onlyabout diffi culties in the processing of information aboutother people but also about processing of self-referentialinformation the relationship that self has in a socialcontext and the potential for using self as a proxy tounderstand the social world

A consistent network of brain regionsmdashincluding themedial prefrontal cortex superior temporal sulcustemporoparietal junction amygdala and fusiform gyrusmdashare hypoactive in autism across tasks in which socialperception and cognition are used100107108 Dysfunction inthe so-called mirror system (ie brain regions that are activeboth when an individual performs an action and observes

that frontal parietal and striatal circuitry are themain systems implicated in executive dysfunction inautism107108 Executive dysfunction is not specific toautism it is commonly reported in other neuropsychiatricconditions (although with diff erent patterns) One viewis that strong executive function early in life could protectat-risk individuals from autism or other neurodevelop-

mental conditions by compensating for deficits in otherbrain systems112

Individuals with autism often have a preference for andsuperiority in processing of local rather than globalsensory-perceptual features (table 4) Individuals withoutautism often show the opposite profile This diff erencecould explain the excellent attention to detail enhancedsensory-perceptual processing and discrimination andidiosyncratic sensory responsivity (ie hyper-reactivity orhyporeactivity to sensory input or unusual interest insensory features of the environment) in autism It couldalso contribute to the exceptional abilities disproportion-ately recorded in individuals with autism113114 Addition-ally top-down information processing in individuals withautism is often characterised by reduced recognition ofthe global context115 and a strong preference to deriverule-based systems113 The neural bases are spatiallydistributed and task dependent but converge onenhanced recruitment of primary sensory cortices

volume and microstructural properties)121ndash123 moleculargenetics (cell adhesion molecules and synaptic proteinsand excitatoryndashinhibitory imbalance)124 and informationprocessing have given rise to the idea that autism ischaracterised by atypical neural connectivity rather thanby a discrete set of atypical brain regions Ideas about theprecise way in which connectivity is atypical vary from

decreased fronto-posterior and enhanced parietal-occipitalconnectivity117125 reduced long-range and increased short-range connectivity126 to temporal binding deficits127 Al-though none fully explains all the data (findings dependon the definition of connectivity the developmental stageof the individual the spatial and temporal scales task vs no-task conditions how motion artifacts are handled andspecific neural systems of concern) they support theheuristic value of the tenet that neural networks in autismare atypical in various ways

One frequently reported neuroanatomical feature ofautism is a trajectory of generalised early brain over-growth when aged 6ndash24 months128 Other than increasesin total brain volume the amygdala is enlarged in youngchildren with autism129 although this enlargement is nolonger present by adolescence130 Early brain overgrowthtends to be reported more in boys who have develop-mental regression than in other subgroups131 and mightbe a result of generalised physical overgrowth132 or biased

mutations with large eff ect sizes and common variationswith smaller eff ect sizes have a role124151

Rare mutations (ie minor allele frequency lt5 in thegeneral population) are frequently identified in autism andcan occur in the form of Mendelian genetic syndromes (so-called syndromic autism occurring in about 5 of allindividuals with autism) chromosomal abnormalities

(about 5) rare copy number variations (5ndash10)151ndash153 andde novo and transmitted point mutations (single nucleotidevariants) identified by exome sequencing150153 De novomutations (copy number variations in the form of micro-deletion or microduplication and single nucleotide vari-ants in the form of nonsense splice-site and frameshiftmutations) that occurred in the germline (especiallypaternal) have a large eff ect size and could be causal37ndash41 particularly in simplex cases (ie when only one individualin the family has autism) Equally copy number variationswith moderate eff ect sizes and variable expressivity andpenetrance could have some role124 However each identi-fied copy number variation only occurs in at most about1 of individuals with autism again suggesting sub-stantial genetic heterogeneity152 Some of these raremutations are clinically identifiable therefore screening isrecommended as part of routine clinical examination9495

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

Clinical guidance available17 18

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

I

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Autism could potentially be subgrouped at clinical (egby developmental pattern or trajectory and comorbidity)cognitive and aetiological levels (eg by genetic andenvironmental correlates)6 Although the term autismspectrum disorder is frequently used the term autismspectrum condition also signals a biomedical diagnosisfor which individuals need support and recognises areasin which aff ected individuals are diff erent from thosewithout autism but without the negative overtones of the

disorder label

EpidemiologyPrevalenceThe prevalence of autism has been steadily increasingsince the first epidemiological study7 which showed that4middot1 of every 10 000 individuals in the UK had autism Theincrease is probably partly a result of changes in diag-nostic concepts and criteria8 However the prevalencehas continued to rise in the past two decades particularly

in individuals without intellectual disability despite

Although many (high-functioning) individuals withautism achieve some degree of explicit or controlledmentalising101 the implicit automatic and intuitivecomponents are still impaired even in adulthood102 Early-onset mentalising diffi culties seem to be specific toautism but late-onset deficits are reported in disorderssuch as schizophrenia103 Mentalising is closely entwined

with executive control and language104 so that thedichotomous view of social versus non-social cognition ispotentially misleading in autism

Historically the domain of mentalising has beenlargely centred on others but self-referential cognitionand its neural substrates are also atypical in autism105106 Therefore deficits in the social domain are not onlyabout diffi culties in the processing of information aboutother people but also about processing of self-referentialinformation the relationship that self has in a socialcontext and the potential for using self as a proxy tounderstand the social world

A consistent network of brain regionsmdashincluding themedial prefrontal cortex superior temporal sulcustemporoparietal junction amygdala and fusiform gyrusmdashare hypoactive in autism across tasks in which socialperception and cognition are used100107108 Dysfunction inthe so-called mirror system (ie brain regions that are activeboth when an individual performs an action and observes

that frontal parietal and striatal circuitry are themain systems implicated in executive dysfunction inautism107108 Executive dysfunction is not specific toautism it is commonly reported in other neuropsychiatricconditions (although with diff erent patterns) One viewis that strong executive function early in life could protectat-risk individuals from autism or other neurodevelop-

mental conditions by compensating for deficits in otherbrain systems112

Individuals with autism often have a preference for andsuperiority in processing of local rather than globalsensory-perceptual features (table 4) Individuals withoutautism often show the opposite profile This diff erencecould explain the excellent attention to detail enhancedsensory-perceptual processing and discrimination andidiosyncratic sensory responsivity (ie hyper-reactivity orhyporeactivity to sensory input or unusual interest insensory features of the environment) in autism It couldalso contribute to the exceptional abilities disproportion-ately recorded in individuals with autism113114 Addition-ally top-down information processing in individuals withautism is often characterised by reduced recognition ofthe global context115 and a strong preference to deriverule-based systems113 The neural bases are spatiallydistributed and task dependent but converge onenhanced recruitment of primary sensory cortices

volume and microstructural properties)121ndash123 moleculargenetics (cell adhesion molecules and synaptic proteinsand excitatoryndashinhibitory imbalance)124 and informationprocessing have given rise to the idea that autism ischaracterised by atypical neural connectivity rather thanby a discrete set of atypical brain regions Ideas about theprecise way in which connectivity is atypical vary from

decreased fronto-posterior and enhanced parietal-occipitalconnectivity117125 reduced long-range and increased short-range connectivity126 to temporal binding deficits127 Al-though none fully explains all the data (findings dependon the definition of connectivity the developmental stageof the individual the spatial and temporal scales task vs no-task conditions how motion artifacts are handled andspecific neural systems of concern) they support theheuristic value of the tenet that neural networks in autismare atypical in various ways

One frequently reported neuroanatomical feature ofautism is a trajectory of generalised early brain over-growth when aged 6ndash24 months128 Other than increasesin total brain volume the amygdala is enlarged in youngchildren with autism129 although this enlargement is nolonger present by adolescence130 Early brain overgrowthtends to be reported more in boys who have develop-mental regression than in other subgroups131 and mightbe a result of generalised physical overgrowth132 or biased

mutations with large eff ect sizes and common variationswith smaller eff ect sizes have a role124151

Rare mutations (ie minor allele frequency lt5 in thegeneral population) are frequently identified in autism andcan occur in the form of Mendelian genetic syndromes (so-called syndromic autism occurring in about 5 of allindividuals with autism) chromosomal abnormalities

(about 5) rare copy number variations (5ndash10)151ndash153 andde novo and transmitted point mutations (single nucleotidevariants) identified by exome sequencing150153 De novomutations (copy number variations in the form of micro-deletion or microduplication and single nucleotide vari-ants in the form of nonsense splice-site and frameshiftmutations) that occurred in the germline (especiallypaternal) have a large eff ect size and could be causal37ndash41 particularly in simplex cases (ie when only one individualin the family has autism) Equally copy number variationswith moderate eff ect sizes and variable expressivity andpenetrance could have some role124 However each identi-fied copy number variation only occurs in at most about1 of individuals with autism again suggesting sub-stantial genetic heterogeneity152 Some of these raremutations are clinically identifiable therefore screening isrecommended as part of routine clinical examination9495

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

I

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Could be a result of empathy diffi culties anxiety sensory overload disruption of routines and diffi culties with communication

Self-injurious behaviours le50 Associated with impulsivity and hyperactivity negative aff ect and lower levels of ability and speech

Could signal frustration in individuals with reduced communication as well as anxiety sensory overload or disruption of routines

Could also become a repetitive habit

Could cause tissue damage and need for restraint

Early signs and screeningEarly identification allows early intervention Previouslychildren with autism were often identified when olderthan 3ndash4 years but toddlers are now frequently diag-

nosed because atypical development is recognised earlyEarly indicators are deficits or delays in the emergence ofjoint attention (ie shared focus on an object) and pretendplay atypical implicit perspective taking deficits inreciprocal aff ective behaviour decreased response to ownname decreased imitation delayed verbal and non-verbal communication motor delay unusually repetitivebehaviours atypical visuomotor exploration inflexibilityin disengaging visual attention and extreme variation intemperament7879 These indicators contribute to screen-ing and diagnostic instruments for toddlers79 How-ever identification of high-functioning individuals is stilloften later than it should be80 particularly for females2324

Variability in age cognitive ability and sex leads todiff erential presentation and the need for appropriatescreening instruments (table 3) Care should be takenduring selection of screening instruments (and the cutoff for further action) because the target sample and purposeof screening vary81 Routine early screening at ages 18 and

Clinical assessmentDiagnostic assessment should be multidisciplinary anduse a developmental framework of an interview with theparent or caregiver interaction with the individualcollection of information about behaviour in communitysettings (eg school reports and job performance)cognitive assessments and a medical examination92 Co-

occurring conditions should be carefully screenedThe interview of the parent or caregiver should cover

the gestational birth developmental and health historyand family medical and psychiatric history It shouldhave specific foci the development of social emotionallanguage and communication cognitive motor and self-help skills the sensory profile and unusual behavioursand interests Behavioural presentation across diff erentcontexts should be investigated Ideally a standardisedstructured interview should be incorporated into theassessment process (table 3) Adaptive skills should bechecked with standardised instruments (eg Vinelandadaptive behaviour scales) In children parentndashchildinteraction and parent coping strategies should bespecifically investigated because they are relevant for theplanning of interventions

Interviews with the individual should be interactiveand engaging to enable assessment of social-communi-cation characteristics in both structured and unstructured

Although many (high-functioning) individuals withautism achieve some degree of explicit or controlledmentalising101 the implicit automatic and intuitivecomponents are still impaired even in adulthood102 Early-onset mentalising diffi culties seem to be specific toautism but late-onset deficits are reported in disorderssuch as schizophrenia103 Mentalising is closely entwined

with executive control and language104 so that thedichotomous view of social versus non-social cognition ispotentially misleading in autism

Historically the domain of mentalising has beenlargely centred on others but self-referential cognitionand its neural substrates are also atypical in autism105106 Therefore deficits in the social domain are not onlyabout diffi culties in the processing of information aboutother people but also about processing of self-referentialinformation the relationship that self has in a socialcontext and the potential for using self as a proxy tounderstand the social world

A consistent network of brain regionsmdashincluding themedial prefrontal cortex superior temporal sulcustemporoparietal junction amygdala and fusiform gyrusmdashare hypoactive in autism across tasks in which socialperception and cognition are used100107108 Dysfunction inthe so-called mirror system (ie brain regions that are activeboth when an individual performs an action and observes

that frontal parietal and striatal circuitry are themain systems implicated in executive dysfunction inautism107108 Executive dysfunction is not specific toautism it is commonly reported in other neuropsychiatricconditions (although with diff erent patterns) One viewis that strong executive function early in life could protectat-risk individuals from autism or other neurodevelop-

mental conditions by compensating for deficits in otherbrain systems112

Individuals with autism often have a preference for andsuperiority in processing of local rather than globalsensory-perceptual features (table 4) Individuals withoutautism often show the opposite profile This diff erencecould explain the excellent attention to detail enhancedsensory-perceptual processing and discrimination andidiosyncratic sensory responsivity (ie hyper-reactivity orhyporeactivity to sensory input or unusual interest insensory features of the environment) in autism It couldalso contribute to the exceptional abilities disproportion-ately recorded in individuals with autism113114 Addition-ally top-down information processing in individuals withautism is often characterised by reduced recognition ofthe global context115 and a strong preference to deriverule-based systems113 The neural bases are spatiallydistributed and task dependent but converge onenhanced recruitment of primary sensory cortices

volume and microstructural properties)121ndash123 moleculargenetics (cell adhesion molecules and synaptic proteinsand excitatoryndashinhibitory imbalance)124 and informationprocessing have given rise to the idea that autism ischaracterised by atypical neural connectivity rather thanby a discrete set of atypical brain regions Ideas about theprecise way in which connectivity is atypical vary from

decreased fronto-posterior and enhanced parietal-occipitalconnectivity117125 reduced long-range and increased short-range connectivity126 to temporal binding deficits127 Al-though none fully explains all the data (findings dependon the definition of connectivity the developmental stageof the individual the spatial and temporal scales task vs no-task conditions how motion artifacts are handled andspecific neural systems of concern) they support theheuristic value of the tenet that neural networks in autismare atypical in various ways

One frequently reported neuroanatomical feature ofautism is a trajectory of generalised early brain over-growth when aged 6ndash24 months128 Other than increasesin total brain volume the amygdala is enlarged in youngchildren with autism129 although this enlargement is nolonger present by adolescence130 Early brain overgrowthtends to be reported more in boys who have develop-mental regression than in other subgroups131 and mightbe a result of generalised physical overgrowth132 or biased

In autism alterations in both serotonin andγ-aminobutyric-acid (GABA) systems have been reportedquite consistently145 such as hyperserotonaemia and analtered developmental trajectory of brain serotoninsynthesis capacity and reduction in the expression ofGABA synthetic enzymes and receptors Because of theirrelation with affi liative and social behaviours theoxytocin and vasopressin systemsrsquo roles in social impair-ments in autism are an active focus of investigationincluding treatment trials146 The role of androgens (andoestrogens) in modulation of risks and protectionsparticularly prenatally in the emergence of autism is also

mutations with large eff ect sizes and common variationswith smaller eff ect sizes have a role124151

Rare mutations (ie minor allele frequency lt5 in thegeneral population) are frequently identified in autism andcan occur in the form of Mendelian genetic syndromes (so-called syndromic autism occurring in about 5 of allindividuals with autism) chromosomal abnormalities

(about 5) rare copy number variations (5ndash10)151ndash153 andde novo and transmitted point mutations (single nucleotidevariants) identified by exome sequencing150153 De novomutations (copy number variations in the form of micro-deletion or microduplication and single nucleotide vari-ants in the form of nonsense splice-site and frameshiftmutations) that occurred in the germline (especiallypaternal) have a large eff ect size and could be causal37ndash41 particularly in simplex cases (ie when only one individualin the family has autism) Equally copy number variationswith moderate eff ect sizes and variable expressivity andpenetrance could have some role124 However each identi-fied copy number variation only occurs in at most about1 of individuals with autism again suggesting sub-stantial genetic heterogeneity152 Some of these raremutations are clinically identifiable therefore screening isrecommended as part of routine clinical examination9495

Behavioural approachesVarious behavioural approaches exist156ndash158 and are classi-fied here into five complementary categories (table 5)Comprehensive approaches target a broad range of skills(cognitive language sensorimotor and adaptive behav-iours) via long-term intensive programmes and aregrouped into applied behaviour analysis and structuredteaching (table 5)159 The models based on applied behav-iour analysis originate from the Lovaas method160 and arecollectively referred to as early intensive behaviouralintervention The Early Start Denver Model is a furtherdevelopment in which a developmental framework andrelationship aspects are emphasised (table 5) Earlyintensive behavioural intervention seems to enable thedevelopment of intelligence communication and adap-tive function and to a lesser extent language daily livingskills and socialisation161 A shift from atypical to typi-cal neurophysiology has been reported after 2 years of

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

Clinical guidance available17 18

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

I

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Although many (high-functioning) individuals withautism achieve some degree of explicit or controlledmentalising101 the implicit automatic and intuitivecomponents are still impaired even in adulthood102 Early-onset mentalising diffi culties seem to be specific toautism but late-onset deficits are reported in disorderssuch as schizophrenia103 Mentalising is closely entwined

with executive control and language104 so that thedichotomous view of social versus non-social cognition ispotentially misleading in autism

Historically the domain of mentalising has beenlargely centred on others but self-referential cognitionand its neural substrates are also atypical in autism105106 Therefore deficits in the social domain are not onlyabout diffi culties in the processing of information aboutother people but also about processing of self-referentialinformation the relationship that self has in a socialcontext and the potential for using self as a proxy tounderstand the social world

A consistent network of brain regionsmdashincluding themedial prefrontal cortex superior temporal sulcustemporoparietal junction amygdala and fusiform gyrusmdashare hypoactive in autism across tasks in which socialperception and cognition are used100107108 Dysfunction inthe so-called mirror system (ie brain regions that are activeboth when an individual performs an action and observes

that frontal parietal and striatal circuitry are themain systems implicated in executive dysfunction inautism107108 Executive dysfunction is not specific toautism it is commonly reported in other neuropsychiatricconditions (although with diff erent patterns) One viewis that strong executive function early in life could protectat-risk individuals from autism or other neurodevelop-

mental conditions by compensating for deficits in otherbrain systems112

Individuals with autism often have a preference for andsuperiority in processing of local rather than globalsensory-perceptual features (table 4) Individuals withoutautism often show the opposite profile This diff erencecould explain the excellent attention to detail enhancedsensory-perceptual processing and discrimination andidiosyncratic sensory responsivity (ie hyper-reactivity orhyporeactivity to sensory input or unusual interest insensory features of the environment) in autism It couldalso contribute to the exceptional abilities disproportion-ately recorded in individuals with autism113114 Addition-ally top-down information processing in individuals withautism is often characterised by reduced recognition ofthe global context115 and a strong preference to deriverule-based systems113 The neural bases are spatiallydistributed and task dependent but converge onenhanced recruitment of primary sensory cortices

volume and microstructural properties)121ndash123 moleculargenetics (cell adhesion molecules and synaptic proteinsand excitatoryndashinhibitory imbalance)124 and informationprocessing have given rise to the idea that autism ischaracterised by atypical neural connectivity rather thanby a discrete set of atypical brain regions Ideas about theprecise way in which connectivity is atypical vary from

decreased fronto-posterior and enhanced parietal-occipitalconnectivity117125 reduced long-range and increased short-range connectivity126 to temporal binding deficits127 Al-though none fully explains all the data (findings dependon the definition of connectivity the developmental stageof the individual the spatial and temporal scales task vs no-task conditions how motion artifacts are handled andspecific neural systems of concern) they support theheuristic value of the tenet that neural networks in autismare atypical in various ways

One frequently reported neuroanatomical feature ofautism is a trajectory of generalised early brain over-growth when aged 6ndash24 months128 Other than increasesin total brain volume the amygdala is enlarged in youngchildren with autism129 although this enlargement is nolonger present by adolescence130 Early brain overgrowthtends to be reported more in boys who have develop-mental regression than in other subgroups131 and mightbe a result of generalised physical overgrowth132 or biased

mutations with large eff ect sizes and common variationswith smaller eff ect sizes have a role124151

Rare mutations (ie minor allele frequency lt5 in thegeneral population) are frequently identified in autism andcan occur in the form of Mendelian genetic syndromes (so-called syndromic autism occurring in about 5 of allindividuals with autism) chromosomal abnormalities

(about 5) rare copy number variations (5ndash10)151ndash153 andde novo and transmitted point mutations (single nucleotidevariants) identified by exome sequencing150153 De novomutations (copy number variations in the form of micro-deletion or microduplication and single nucleotide vari-ants in the form of nonsense splice-site and frameshiftmutations) that occurred in the germline (especiallypaternal) have a large eff ect size and could be causal37ndash41 particularly in simplex cases (ie when only one individualin the family has autism) Equally copy number variationswith moderate eff ect sizes and variable expressivity andpenetrance could have some role124 However each identi-fied copy number variation only occurs in at most about1 of individuals with autism again suggesting sub-stantial genetic heterogeneity152 Some of these raremutations are clinically identifiable therefore screening isrecommended as part of routine clinical examination9495

Behavioural approachesVarious behavioural approaches exist156ndash158 and are classi-fied here into five complementary categories (table 5)Comprehensive approaches target a broad range of skills(cognitive language sensorimotor and adaptive behav-iours) via long-term intensive programmes and aregrouped into applied behaviour analysis and structuredteaching (table 5)159 The models based on applied behav-iour analysis originate from the Lovaas method160 and arecollectively referred to as early intensive behaviouralintervention The Early Start Denver Model is a furtherdevelopment in which a developmental framework andrelationship aspects are emphasised (table 5) Earlyintensive behavioural intervention seems to enable thedevelopment of intelligence communication and adap-tive function and to a lesser extent language daily livingskills and socialisation161 A shift from atypical to typi-cal neurophysiology has been reported after 2 years of

Sensory integration therapymdashfrequently used inoccupational therapymdashis sometimes off ered as one

component of a comprehensive programme to addresssensory-based problems However its eff ectiveness isinconclusive167 and it should not be considered as aroutine intervention for autism168

The US Health Resources and Services Administration158 and the UK National Institute for Health and CareExcellence74 have provided clinical guidelines for behav-

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Early signs and screeningEarly identification allows early intervention Previouslychildren with autism were often identified when olderthan 3ndash4 years but toddlers are now frequently diag-

nosed because atypical development is recognised earlyEarly indicators are deficits or delays in the emergence ofjoint attention (ie shared focus on an object) and pretendplay atypical implicit perspective taking deficits inreciprocal aff ective behaviour decreased response to ownname decreased imitation delayed verbal and non-verbal communication motor delay unusually repetitivebehaviours atypical visuomotor exploration inflexibilityin disengaging visual attention and extreme variation intemperament7879 These indicators contribute to screen-ing and diagnostic instruments for toddlers79 How-ever identification of high-functioning individuals is stilloften later than it should be80 particularly for females2324

Variability in age cognitive ability and sex leads todiff erential presentation and the need for appropriatescreening instruments (table 3) Care should be takenduring selection of screening instruments (and the cutoff for further action) because the target sample and purposeof screening vary81 Routine early screening at ages 18 and

Clinical assessmentDiagnostic assessment should be multidisciplinary anduse a developmental framework of an interview with theparent or caregiver interaction with the individualcollection of information about behaviour in communitysettings (eg school reports and job performance)cognitive assessments and a medical examination92 Co-

occurring conditions should be carefully screenedThe interview of the parent or caregiver should cover

the gestational birth developmental and health historyand family medical and psychiatric history It shouldhave specific foci the development of social emotionallanguage and communication cognitive motor and self-help skills the sensory profile and unusual behavioursand interests Behavioural presentation across diff erentcontexts should be investigated Ideally a standardisedstructured interview should be incorporated into theassessment process (table 3) Adaptive skills should bechecked with standardised instruments (eg Vinelandadaptive behaviour scales) In children parentndashchildinteraction and parent coping strategies should bespecifically investigated because they are relevant for theplanning of interventions

Interviews with the individual should be interactiveand engaging to enable assessment of social-communi-cation characteristics in both structured and unstructured

Although many (high-functioning) individuals withautism achieve some degree of explicit or controlledmentalising101 the implicit automatic and intuitivecomponents are still impaired even in adulthood102 Early-onset mentalising diffi culties seem to be specific toautism but late-onset deficits are reported in disorderssuch as schizophrenia103 Mentalising is closely entwined

with executive control and language104 so that thedichotomous view of social versus non-social cognition ispotentially misleading in autism

Historically the domain of mentalising has beenlargely centred on others but self-referential cognitionand its neural substrates are also atypical in autism105106 Therefore deficits in the social domain are not onlyabout diffi culties in the processing of information aboutother people but also about processing of self-referentialinformation the relationship that self has in a socialcontext and the potential for using self as a proxy tounderstand the social world

A consistent network of brain regionsmdashincluding themedial prefrontal cortex superior temporal sulcustemporoparietal junction amygdala and fusiform gyrusmdashare hypoactive in autism across tasks in which socialperception and cognition are used100107108 Dysfunction inthe so-called mirror system (ie brain regions that are activeboth when an individual performs an action and observes

that frontal parietal and striatal circuitry are themain systems implicated in executive dysfunction inautism107108 Executive dysfunction is not specific toautism it is commonly reported in other neuropsychiatricconditions (although with diff erent patterns) One viewis that strong executive function early in life could protectat-risk individuals from autism or other neurodevelop-

mental conditions by compensating for deficits in otherbrain systems112

Individuals with autism often have a preference for andsuperiority in processing of local rather than globalsensory-perceptual features (table 4) Individuals withoutautism often show the opposite profile This diff erencecould explain the excellent attention to detail enhancedsensory-perceptual processing and discrimination andidiosyncratic sensory responsivity (ie hyper-reactivity orhyporeactivity to sensory input or unusual interest insensory features of the environment) in autism It couldalso contribute to the exceptional abilities disproportion-ately recorded in individuals with autism113114 Addition-ally top-down information processing in individuals withautism is often characterised by reduced recognition ofthe global context115 and a strong preference to deriverule-based systems113 The neural bases are spatiallydistributed and task dependent but converge onenhanced recruitment of primary sensory cortices

volume and microstructural properties)121ndash123 moleculargenetics (cell adhesion molecules and synaptic proteinsand excitatoryndashinhibitory imbalance)124 and informationprocessing have given rise to the idea that autism ischaracterised by atypical neural connectivity rather thanby a discrete set of atypical brain regions Ideas about theprecise way in which connectivity is atypical vary from

decreased fronto-posterior and enhanced parietal-occipitalconnectivity117125 reduced long-range and increased short-range connectivity126 to temporal binding deficits127 Al-though none fully explains all the data (findings dependon the definition of connectivity the developmental stageof the individual the spatial and temporal scales task vs no-task conditions how motion artifacts are handled andspecific neural systems of concern) they support theheuristic value of the tenet that neural networks in autismare atypical in various ways

One frequently reported neuroanatomical feature ofautism is a trajectory of generalised early brain over-growth when aged 6ndash24 months128 Other than increasesin total brain volume the amygdala is enlarged in youngchildren with autism129 although this enlargement is nolonger present by adolescence130 Early brain overgrowthtends to be reported more in boys who have develop-mental regression than in other subgroups131 and mightbe a result of generalised physical overgrowth132 or biased

In autism alterations in both serotonin andγ-aminobutyric-acid (GABA) systems have been reportedquite consistently145 such as hyperserotonaemia and analtered developmental trajectory of brain serotoninsynthesis capacity and reduction in the expression ofGABA synthetic enzymes and receptors Because of theirrelation with affi liative and social behaviours theoxytocin and vasopressin systemsrsquo roles in social impair-ments in autism are an active focus of investigationincluding treatment trials146 The role of androgens (andoestrogens) in modulation of risks and protectionsparticularly prenatally in the emergence of autism is also

mutations with large eff ect sizes and common variationswith smaller eff ect sizes have a role124151

Rare mutations (ie minor allele frequency lt5 in thegeneral population) are frequently identified in autism andcan occur in the form of Mendelian genetic syndromes (so-called syndromic autism occurring in about 5 of allindividuals with autism) chromosomal abnormalities

(about 5) rare copy number variations (5ndash10)151ndash153 andde novo and transmitted point mutations (single nucleotidevariants) identified by exome sequencing150153 De novomutations (copy number variations in the form of micro-deletion or microduplication and single nucleotide vari-ants in the form of nonsense splice-site and frameshiftmutations) that occurred in the germline (especiallypaternal) have a large eff ect size and could be causal37ndash41 particularly in simplex cases (ie when only one individualin the family has autism) Equally copy number variationswith moderate eff ect sizes and variable expressivity andpenetrance could have some role124 However each identi-fied copy number variation only occurs in at most about1 of individuals with autism again suggesting sub-stantial genetic heterogeneity152 Some of these raremutations are clinically identifiable therefore screening isrecommended as part of routine clinical examination9495

Behavioural approachesVarious behavioural approaches exist156ndash158 and are classi-fied here into five complementary categories (table 5)Comprehensive approaches target a broad range of skills(cognitive language sensorimotor and adaptive behav-iours) via long-term intensive programmes and aregrouped into applied behaviour analysis and structuredteaching (table 5)159 The models based on applied behav-iour analysis originate from the Lovaas method160 and arecollectively referred to as early intensive behaviouralintervention The Early Start Denver Model is a furtherdevelopment in which a developmental framework andrelationship aspects are emphasised (table 5) Earlyintensive behavioural intervention seems to enable thedevelopment of intelligence communication and adap-tive function and to a lesser extent language daily livingskills and socialisation161 A shift from atypical to typi-cal neurophysiology has been reported after 2 years of

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Although many (high-functioning) individuals withautism achieve some degree of explicit or controlledmentalising101 the implicit automatic and intuitivecomponents are still impaired even in adulthood102 Early-onset mentalising diffi culties seem to be specific toautism but late-onset deficits are reported in disorderssuch as schizophrenia103 Mentalising is closely entwined

with executive control and language104 so that thedichotomous view of social versus non-social cognition ispotentially misleading in autism

Historically the domain of mentalising has beenlargely centred on others but self-referential cognitionand its neural substrates are also atypical in autism105106 Therefore deficits in the social domain are not onlyabout diffi culties in the processing of information aboutother people but also about processing of self-referentialinformation the relationship that self has in a socialcontext and the potential for using self as a proxy tounderstand the social world

A consistent network of brain regionsmdashincluding themedial prefrontal cortex superior temporal sulcustemporoparietal junction amygdala and fusiform gyrusmdashare hypoactive in autism across tasks in which socialperception and cognition are used100107108 Dysfunction inthe so-called mirror system (ie brain regions that are activeboth when an individual performs an action and observes

that frontal parietal and striatal circuitry are themain systems implicated in executive dysfunction inautism107108 Executive dysfunction is not specific toautism it is commonly reported in other neuropsychiatricconditions (although with diff erent patterns) One viewis that strong executive function early in life could protectat-risk individuals from autism or other neurodevelop-

mental conditions by compensating for deficits in otherbrain systems112

Individuals with autism often have a preference for andsuperiority in processing of local rather than globalsensory-perceptual features (table 4) Individuals withoutautism often show the opposite profile This diff erencecould explain the excellent attention to detail enhancedsensory-perceptual processing and discrimination andidiosyncratic sensory responsivity (ie hyper-reactivity orhyporeactivity to sensory input or unusual interest insensory features of the environment) in autism It couldalso contribute to the exceptional abilities disproportion-ately recorded in individuals with autism113114 Addition-ally top-down information processing in individuals withautism is often characterised by reduced recognition ofthe global context115 and a strong preference to deriverule-based systems113 The neural bases are spatiallydistributed and task dependent but converge onenhanced recruitment of primary sensory cortices

volume and microstructural properties)121ndash123 moleculargenetics (cell adhesion molecules and synaptic proteinsand excitatoryndashinhibitory imbalance)124 and informationprocessing have given rise to the idea that autism ischaracterised by atypical neural connectivity rather thanby a discrete set of atypical brain regions Ideas about theprecise way in which connectivity is atypical vary from

decreased fronto-posterior and enhanced parietal-occipitalconnectivity117125 reduced long-range and increased short-range connectivity126 to temporal binding deficits127 Al-though none fully explains all the data (findings dependon the definition of connectivity the developmental stageof the individual the spatial and temporal scales task vs no-task conditions how motion artifacts are handled andspecific neural systems of concern) they support theheuristic value of the tenet that neural networks in autismare atypical in various ways

One frequently reported neuroanatomical feature ofautism is a trajectory of generalised early brain over-growth when aged 6ndash24 months128 Other than increasesin total brain volume the amygdala is enlarged in youngchildren with autism129 although this enlargement is nolonger present by adolescence130 Early brain overgrowthtends to be reported more in boys who have develop-mental regression than in other subgroups131 and mightbe a result of generalised physical overgrowth132 or biased

In autism alterations in both serotonin andγ-aminobutyric-acid (GABA) systems have been reportedquite consistently145 such as hyperserotonaemia and analtered developmental trajectory of brain serotoninsynthesis capacity and reduction in the expression ofGABA synthetic enzymes and receptors Because of theirrelation with affi liative and social behaviours theoxytocin and vasopressin systemsrsquo roles in social impair-ments in autism are an active focus of investigationincluding treatment trials146 The role of androgens (andoestrogens) in modulation of risks and protectionsparticularly prenatally in the emergence of autism is also

mutations with large eff ect sizes and common variationswith smaller eff ect sizes have a role124151

Rare mutations (ie minor allele frequency lt5 in thegeneral population) are frequently identified in autism andcan occur in the form of Mendelian genetic syndromes (so-called syndromic autism occurring in about 5 of allindividuals with autism) chromosomal abnormalities

(about 5) rare copy number variations (5ndash10)151ndash153 andde novo and transmitted point mutations (single nucleotidevariants) identified by exome sequencing150153 De novomutations (copy number variations in the form of micro-deletion or microduplication and single nucleotide vari-ants in the form of nonsense splice-site and frameshiftmutations) that occurred in the germline (especiallypaternal) have a large eff ect size and could be causal37ndash41 particularly in simplex cases (ie when only one individualin the family has autism) Equally copy number variationswith moderate eff ect sizes and variable expressivity andpenetrance could have some role124 However each identi-fied copy number variation only occurs in at most about1 of individuals with autism again suggesting sub-stantial genetic heterogeneity152 Some of these raremutations are clinically identifiable therefore screening isrecommended as part of routine clinical examination9495

Behavioural approachesVarious behavioural approaches exist156ndash158 and are classi-fied here into five complementary categories (table 5)Comprehensive approaches target a broad range of skills(cognitive language sensorimotor and adaptive behav-iours) via long-term intensive programmes and aregrouped into applied behaviour analysis and structuredteaching (table 5)159 The models based on applied behav-iour analysis originate from the Lovaas method160 and arecollectively referred to as early intensive behaviouralintervention The Early Start Denver Model is a furtherdevelopment in which a developmental framework andrelationship aspects are emphasised (table 5) Earlyintensive behavioural intervention seems to enable thedevelopment of intelligence communication and adap-tive function and to a lesser extent language daily livingskills and socialisation161 A shift from atypical to typi-cal neurophysiology has been reported after 2 years of

Nevertheless parental and family involvement isimportant in therapist-mediated programmes79158

Sensory integration therapymdashfrequently used inoccupational therapymdashis sometimes off ered as one

component of a comprehensive programme to addresssensory-based problems However its eff ectiveness isinconclusive167 and it should not be considered as aroutine intervention for autism168

The US Health Resources and Services Administration158 and the UK National Institute for Health and CareExcellence74 have provided clinical guidelines for behav-

ioural interventions They stress that comprehensiveintervention should immediately follow diagnosis andshould be individualised (on the basis of developmen-tal level needs and assets) and engage the family

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Although many (high-functioning) individuals withautism achieve some degree of explicit or controlledmentalising101 the implicit automatic and intuitivecomponents are still impaired even in adulthood102 Early-onset mentalising diffi culties seem to be specific toautism but late-onset deficits are reported in disorderssuch as schizophrenia103 Mentalising is closely entwined

with executive control and language104 so that thedichotomous view of social versus non-social cognition ispotentially misleading in autism

Historically the domain of mentalising has beenlargely centred on others but self-referential cognitionand its neural substrates are also atypical in autism105106 Therefore deficits in the social domain are not onlyabout diffi culties in the processing of information aboutother people but also about processing of self-referentialinformation the relationship that self has in a socialcontext and the potential for using self as a proxy tounderstand the social world

A consistent network of brain regionsmdashincluding themedial prefrontal cortex superior temporal sulcustemporoparietal junction amygdala and fusiform gyrusmdashare hypoactive in autism across tasks in which socialperception and cognition are used100107108 Dysfunction inthe so-called mirror system (ie brain regions that are activeboth when an individual performs an action and observes

that frontal parietal and striatal circuitry are themain systems implicated in executive dysfunction inautism107108 Executive dysfunction is not specific toautism it is commonly reported in other neuropsychiatricconditions (although with diff erent patterns) One viewis that strong executive function early in life could protectat-risk individuals from autism or other neurodevelop-

mental conditions by compensating for deficits in otherbrain systems112

Individuals with autism often have a preference for andsuperiority in processing of local rather than globalsensory-perceptual features (table 4) Individuals withoutautism often show the opposite profile This diff erencecould explain the excellent attention to detail enhancedsensory-perceptual processing and discrimination andidiosyncratic sensory responsivity (ie hyper-reactivity orhyporeactivity to sensory input or unusual interest insensory features of the environment) in autism It couldalso contribute to the exceptional abilities disproportion-ately recorded in individuals with autism113114 Addition-ally top-down information processing in individuals withautism is often characterised by reduced recognition ofthe global context115 and a strong preference to deriverule-based systems113 The neural bases are spatiallydistributed and task dependent but converge onenhanced recruitment of primary sensory cortices

volume and microstructural properties)121ndash123 moleculargenetics (cell adhesion molecules and synaptic proteinsand excitatoryndashinhibitory imbalance)124 and informationprocessing have given rise to the idea that autism ischaracterised by atypical neural connectivity rather thanby a discrete set of atypical brain regions Ideas about theprecise way in which connectivity is atypical vary from

decreased fronto-posterior and enhanced parietal-occipitalconnectivity117125 reduced long-range and increased short-range connectivity126 to temporal binding deficits127 Al-though none fully explains all the data (findings dependon the definition of connectivity the developmental stageof the individual the spatial and temporal scales task vs no-task conditions how motion artifacts are handled andspecific neural systems of concern) they support theheuristic value of the tenet that neural networks in autismare atypical in various ways

One frequently reported neuroanatomical feature ofautism is a trajectory of generalised early brain over-growth when aged 6ndash24 months128 Other than increasesin total brain volume the amygdala is enlarged in youngchildren with autism129 although this enlargement is nolonger present by adolescence130 Early brain overgrowthtends to be reported more in boys who have develop-mental regression than in other subgroups131 and mightbe a result of generalised physical overgrowth132 or biased

In autism alterations in both serotonin andγ-aminobutyric-acid (GABA) systems have been reportedquite consistently145 such as hyperserotonaemia and analtered developmental trajectory of brain serotoninsynthesis capacity and reduction in the expression ofGABA synthetic enzymes and receptors Because of theirrelation with affi liative and social behaviours theoxytocin and vasopressin systemsrsquo roles in social impair-ments in autism are an active focus of investigationincluding treatment trials146 The role of androgens (andoestrogens) in modulation of risks and protectionsparticularly prenatally in the emergence of autism is also

mutations with large eff ect sizes and common variationswith smaller eff ect sizes have a role124151

Rare mutations (ie minor allele frequency lt5 in thegeneral population) are frequently identified in autism andcan occur in the form of Mendelian genetic syndromes (so-called syndromic autism occurring in about 5 of allindividuals with autism) chromosomal abnormalities

(about 5) rare copy number variations (5ndash10)151ndash153 andde novo and transmitted point mutations (single nucleotidevariants) identified by exome sequencing150153 De novomutations (copy number variations in the form of micro-deletion or microduplication and single nucleotide vari-ants in the form of nonsense splice-site and frameshiftmutations) that occurred in the germline (especiallypaternal) have a large eff ect size and could be causal37ndash41 particularly in simplex cases (ie when only one individualin the family has autism) Equally copy number variationswith moderate eff ect sizes and variable expressivity andpenetrance could have some role124 However each identi-fied copy number variation only occurs in at most about1 of individuals with autism again suggesting sub-stantial genetic heterogeneity152 Some of these raremutations are clinically identifiable therefore screening isrecommended as part of routine clinical examination9495

Behavioural approachesVarious behavioural approaches exist156ndash158 and are classi-fied here into five complementary categories (table 5)Comprehensive approaches target a broad range of skills(cognitive language sensorimotor and adaptive behav-iours) via long-term intensive programmes and aregrouped into applied behaviour analysis and structuredteaching (table 5)159 The models based on applied behav-iour analysis originate from the Lovaas method160 and arecollectively referred to as early intensive behaviouralintervention The Early Start Denver Model is a furtherdevelopment in which a developmental framework andrelationship aspects are emphasised (table 5) Earlyintensive behavioural intervention seems to enable thedevelopment of intelligence communication and adap-tive function and to a lesser extent language daily livingskills and socialisation161 A shift from atypical to typi-cal neurophysiology has been reported after 2 years of

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

I

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

decreased fronto-posterior and enhanced parietal-occipitalconnectivity117125 reduced long-range and increased short-range connectivity126 to temporal binding deficits127 Al-though none fully explains all the data (findings dependon the definition of connectivity the developmental stageof the individual the spatial and temporal scales task vs no-task conditions how motion artifacts are handled andspecific neural systems of concern) they support theheuristic value of the tenet that neural networks in autismare atypical in various ways

One frequently reported neuroanatomical feature ofautism is a trajectory of generalised early brain over-growth when aged 6ndash24 months128 Other than increasesin total brain volume the amygdala is enlarged in youngchildren with autism129 although this enlargement is nolonger present by adolescence130 Early brain overgrowthtends to be reported more in boys who have develop-mental regression than in other subgroups131 and mightbe a result of generalised physical overgrowth132 or biased

In autism alterations in both serotonin andγ-aminobutyric-acid (GABA) systems have been reportedquite consistently145 such as hyperserotonaemia and analtered developmental trajectory of brain serotoninsynthesis capacity and reduction in the expression ofGABA synthetic enzymes and receptors Because of theirrelation with affi liative and social behaviours theoxytocin and vasopressin systemsrsquo roles in social impair-ments in autism are an active focus of investigationincluding treatment trials146 The role of androgens (andoestrogens) in modulation of risks and protectionsparticularly prenatally in the emergence of autism is also

mutations with large eff ect sizes and common variationswith smaller eff ect sizes have a role124151

Rare mutations (ie minor allele frequency lt5 in thegeneral population) are frequently identified in autism andcan occur in the form of Mendelian genetic syndromes (so-called syndromic autism occurring in about 5 of allindividuals with autism) chromosomal abnormalities

(about 5) rare copy number variations (5ndash10)151ndash153 andde novo and transmitted point mutations (single nucleotidevariants) identified by exome sequencing150153 De novomutations (copy number variations in the form of micro-deletion or microduplication and single nucleotide vari-ants in the form of nonsense splice-site and frameshiftmutations) that occurred in the germline (especiallypaternal) have a large eff ect size and could be causal37ndash41 particularly in simplex cases (ie when only one individualin the family has autism) Equally copy number variationswith moderate eff ect sizes and variable expressivity andpenetrance could have some role124 However each identi-fied copy number variation only occurs in at most about1 of individuals with autism again suggesting sub-stantial genetic heterogeneity152 Some of these raremutations are clinically identifiable therefore screening isrecommended as part of routine clinical examination9495

Behavioural approachesVarious behavioural approaches exist156ndash158 and are classi-fied here into five complementary categories (table 5)Comprehensive approaches target a broad range of skills(cognitive language sensorimotor and adaptive behav-iours) via long-term intensive programmes and aregrouped into applied behaviour analysis and structuredteaching (table 5)159 The models based on applied behav-iour analysis originate from the Lovaas method160 and arecollectively referred to as early intensive behaviouralintervention The Early Start Denver Model is a furtherdevelopment in which a developmental framework andrelationship aspects are emphasised (table 5) Earlyintensive behavioural intervention seems to enable thedevelopment of intelligence communication and adap-tive function and to a lesser extent language daily livingskills and socialisation161 A shift from atypical to typi-cal neurophysiology has been reported after 2 years of

Sensory integration therapymdashfrequently used inoccupational therapymdashis sometimes off ered as one

component of a comprehensive programme to addresssensory-based problems However its eff ectiveness isinconclusive167 and it should not be considered as aroutine intervention for autism168

The US Health Resources and Services Administration158 and the UK National Institute for Health and CareExcellence74 have provided clinical guidelines for behav-

ioural interventions They stress that comprehensiveintervention should immediately follow diagnosis andshould be individualised (on the basis of developmen-tal level needs and assets) and engage the family

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

Clinical guidance available17 18

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

I

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

for autism relies less on introspection and more on

teaching of practical adaptive skills with concrete

instructions often combined with social skill training

systematic desensitisation is useful particularly for

individuals with intellectual disability106

ABA to reduce aggression applies functional

behaviour assessment and teaches alternative

(about 5) rare copy number variations (5ndash10)151ndash153 andde novo and transmitted point mutations (single nucleotidevariants) identified by exome sequencing150153 De novomutations (copy number variations in the form of micro-deletion or microduplication and single nucleotide vari-ants in the form of nonsense splice-site and frameshiftmutations) that occurred in the germline (especiallypaternal) have a large eff ect size and could be causal37ndash41 particularly in simplex cases (ie when only one individualin the family has autism) Equally copy number variationswith moderate eff ect sizes and variable expressivity andpenetrance could have some role124 However each identi-fied copy number variation only occurs in at most about1 of individuals with autism again suggesting sub-stantial genetic heterogeneity152 Some of these raremutations are clinically identifiable therefore screening isrecommended as part of routine clinical examination9495

Behavioural approachesVarious behavioural approaches exist156ndash158 and are classi-fied here into five complementary categories (table 5)Comprehensive approaches target a broad range of skills(cognitive language sensorimotor and adaptive behav-iours) via long-term intensive programmes and aregrouped into applied behaviour analysis and structuredteaching (table 5)159 The models based on applied behav-iour analysis originate from the Lovaas method160 and arecollectively referred to as early intensive behaviouralintervention The Early Start Denver Model is a furtherdevelopment in which a developmental framework andrelationship aspects are emphasised (table 5) Earlyintensive behavioural intervention seems to enable thedevelopment of intelligence communication and adap-tive function and to a lesser extent language daily livingskills and socialisation161 A shift from atypical to typi-cal neurophysiology has been reported after 2 years of

Nevertheless parental and family involvement isimportant in therapist-mediated programmes79158

Sensory integration therapymdashfrequently used inoccupational therapymdashis sometimes off ered as one

component of a comprehensive programme to addresssensory-based problems However its eff ectiveness isinconclusive167 and it should not be considered as aroutine intervention for autism168

The US Health Resources and Services Administration158 and the UK National Institute for Health and CareExcellence74 have provided clinical guidelines for behav-

ioural interventions They stress that comprehensiveintervention should immediately follow diagnosis andshould be individualised (on the basis of developmen-tal level needs and assets) and engage the family

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

Sensory integration therapymdashfrequently used inoccupational therapymdashis sometimes off ered as one

component of a comprehensive programme to addresssensory-based problems However its eff ectiveness isinconclusive167 and it should not be considered as aroutine intervention for autism168

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

I

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

I

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

I

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

Clinical guidance available17 18

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

Clinical guidance available17 18

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

I

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

Clinical guidance available17 18

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

I

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Appendix Table 1 Behavioural characteristics of autism

Core features in DSM-5 criteria

Persistent deficits in social communication

and social interaction across multiple

contexts

Deficits in social-emotional reciprocity

Deficits in non-verbal communicative behaviours used for social interaction

Deficits in developing maintaining and understanding relationships

Restricted repetitive patterns of behaviour

interests or activities

Stereotyped or repetitive motor movements use of objects or speech

Insistence on sameness inflexible adherence to routines or ritualised patterns of verbal or

non-verbal behaviour

Highly restricted fixated interests that are abnormal in intensity or focus

Hyper- or hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment

Associated features not in DSM-5 criteria

Atypical language development and

abilities2

Preschool age (lt 6 years) frequently deviant and delayed in comprehension two-thirds have

difficulty with expressive phonology and grammar

School age (≧6 years) deviant pragmatics semantics and morphology with relatively intact

articulation and syntax (ie early difficulties are resolved)

Motor abnormalities Motor delay hypotonia catatonia deficits in coordination movement preparation and planning

praxis gait and balance

Excellent attention to detail

Appendix Table 2 Common co-occurring conditions

Condition Proportion of

individualswith autism

affected

Comments

Developmental

Intellectual disability ~45 Prevalence estimate is affected by the diagnostic boundary and the definition of intelligence

(eg whether verbal ability is used as a criterion)

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

Clinical guidance available17 18

=

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

I

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

In individuals discrepant performance between subtests is common

Language disorders Variable In DSM-IV language delay was a defining feature of autism (autistic disorder) but is nolonger included in DSM-5

An autism-specific language profile (separate from language disorders) exists but with

substantial inter-individual variability2

Attention-deficit hyperactivitydisorder

28-44 - In DSM-IV not diagnosed when occurring in individuals with autism but no longer so inDSM-5

Clinical guidance available11

Tic disorders 14-38 ~6middot5 have Tourettersquos syndrome

Motor abnormality ≦7913 14 See Appendix Table 1

General medical

Epilepsy 8-30 Increased frequency in individuals with intellectual disability or genetic syndromes

Two peaks of onset early childhood and adolescence Increases risk of poor outcome

Clinical guidance available4 16

Gastrointestinal problems 9-70 Common symptoms include chronic constipation abdominal pain chronic diarrhoea and

gastro-oesophageal reflux18

Associated disorders include gastritis oesophagitis gastro-oesophageal reflux disease

inflammatory bowel disease coeliac disease Crohnrsquos disease and colitis19

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Immune dysregulation ≦3820 Altered immune function which interacts with neurodevelopment could be a crucial

biological pathway underpinning autism21 Associated with allergic and autoimmune disorders20 22

Genetic syndromes ~5 Collectively called lsquosyndromic autismrsquo

Examples include fragile X syndrome (21-50 of individuals affected have autism) Rett

syndrome (most have autistic features but with profiles different from idiopathic autism)

tuberous sclerosis complex (24-60) Downrsquos syndrome (5-39) phenylketonuria (5-20)

CHARGE syndrome (coloboma of the eye heart defects atresia of the choanae retardation

of growth and development or both genital and urinary abnormalities or both and ear

abnormalities and deafness 15-50) Angelman syndrome (50-81) Timothy syndrome

(60-70) and Joubert syndrome (~40)

Sleep disorders 50-80 Insomnia is the most common

Clinical guidance available4 26 27

Psychiatric

Anxiety 42-56-

Common across all age groupsMost common are social anxiety disorder (13-29 of individuals with autism clinical

guidance available28) and generalised anxiety disorder (13-22)7-9

High-functioning individuals are more susceptible (or symptoms are more detectable)29

Depression 12-70 - Common in adults less common in children

High-functioning adults who are socially less impaired are more susceptible (or symptoms

are more detectable)30

Obsessive-compulsive disorder 7-24 - Shares the repetitive behaviour domain with autism that may cut across nosological

categories

Important to distinguish between repetitive behaviours that do not involve intrusive

anxiety-causing thoughts or obsessions (part of autism) and those that do (and are part of

obsessive-compulsive disorder)Psychotic disorders 12-17 Mainly in adults

Most commonly recurrent hallucinosis9

G

High frequency of autism-like features (even a diagnosis of autism spectrum disorder or

pervasive developmental disorder) preceding adult-onset (52)31 and childhood-onsetschizophrenia (30-50)32

Substance use disorders ≦16 Potentially because individual is using substances as self-medication to relieve anxiety

Oppositional defiant disorder 16-28 Oppositional behaviours could be a manifestation of anxiety resistance to change stubborn

belief in the correctness of own point of view difficulty seeing anotherrsquos point of view lack

of awareness of the effect of own behaviour on others or lack of interest in social

compliance10

Eating disorders 4-5 Could be a misdiagnosis of autism particularly in female individuals because both involverigid behaviour inflexible cognition self-focus and focus on details33

Personality disorders Particularly in high-functioning adults

Paranoid personality disorder 0-19 Could be secondary to difficulty understanding othersrsquo intentions and negative interpersonal

experiences34

Schizoid personality disorder 21-26 Partially overlapping diagnostic criteria with autism

Similar to Wingrsquos lsquolonersrsquo subgroup35

Schizotypal personality

disorder

2-13 Some overlapping criteria with autism especially those shared with schizoid personality

disorder

Borderline personality disorder 0-9 Could have similarity in behaviours (eg difficulties in interpersonal relationships

misattributing hostile intentions problems with affect regulation) which requires careful

differential diagnosis

Could be a misdiagnosis of autism particularly in female individuals

Obsessive-compulsive

personality disorder

19-32 Partially overlapping diagnostic criteria with autism

Avoidant personality disorder 13-25 Could be secondary to repeated failure in social experiences

Behavioural

Aggressive behaviours ≦6836 Often directed towards caregivers rather than non-caregivers

Could be a result of empathy difficulties anxiety sensory overload disruption of routines

and difficulties with communication

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased

or bullied39

Self-injurious behaviours ≦5037 Associated with impulsivity and hyperactivity negative affect and lower levels of ability and

speech37 Could signal frustration in individuals with reduced communication as well as anxiety

sensory overload or disruption of routines

Could also become a repetitive habitCould cause tissue damage and need for restraint

Pica ~36 More likely in individuals with intellectual disability

Could be a result of a lack of social conformity to cultural categories of what is deemed

edible or sensory exploration or both

Suicidal ideation or attempt 11-14 Risks increase with concurrent depression and behavioural problems and after being teased
