38% Psychosis
21% Severe Depressive Illness
![Page 6: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/6.jpg)
Recommendations - Back to Basics 1Saving Mothers Lives
Anxiety or depression Review in 2 weeks
Consider psych referral if symptoms persist
Refer urgently where:
Suicidal ideation, uncharacteristic symptoms/marked change from normal functioning, morbid fears, profound low mood, personal or family history of serious affective disorder, mental health deterioration, morbid fears, panic attacks and intrusive obsessional thoughts.
![Page 7: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/7.jpg)
Effects of Untreated Illness
Increased morbidity.
Increased risks towards self and others.
Links between maternal anxiety and fetal behaviour and heart rate
Stress/anxiety during pregnancy can have long term effects on child
![Page 8: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/8.jpg)
Associated with an increased incidence of:
Emotional problems - Anxiety/depression
Behavioural problems – ADHD, conduct disorder
Impaired cognitive development, esp language
Sleep problems in infants
Sensitive early mothering important as what happens in utero for child outcome
![Page 9: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/9.jpg)
Effects of antenatal and postnatal depression Children of mothers depressed in perinatal period compared to
children of well mothers:
Lower IQ scores
12x more likely to have a statement of special needs
elevated risk of violence at 11 and 16 years
More likely to suffer separation anxiety at 11 and a diagnosis of depression at 16
![Page 10: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/10.jpg)
Suicide
Majority of deaths secondary to postpartum psychosis or very severe depressive illness
Oates (2008) Suicide rate for ppp 2/1000
Common profile; white, older, 2nd or subsequent pregnancy, married, comfortable circumstances
Likely to die violently
![Page 11: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/11.jpg)
Infanticide
Similar profile
1/3rd mental illness
Death extended suicide or occasionally altruistic based on delusional belief
Highest concern if delusion involves child e.g baby changed, not hers, possessed, evil.
![Page 12: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/12.jpg)

Bipolar Disorder
52% relapse in 1st 40 weeks after stopping treatment
If pregnant and stable on antipsychotic and likely to relapse without medication continue
Up to 70% relapse if untreated in postnatal period 50% psychotic symptoms day 1 - 3
![Page 14: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/14.jpg)

1st contact;
Past or present mental illness
Previous psychiatric input, including admissions
Family history of severe mental illness
![Page 20: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/20.jpg)
Treatment of pregnant and breast feeding women- NICE guidelines
Importance of balancing risks and benefits
Cautious
Women requiring psychological treatment should be seen for treatment within 1 month of assessment and no longer than 3 months.
![Page 21: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/21.jpg)
NICE
Discussion should include:
Risk of relapse and not treating disorder
Woman’s ability to cope with untreated symptoms
Severity of previous episodes and response to treatment
Woman’s preference
Possibility that stopping drug with teratogenic risk once pregnancy confirmed may not remove risk
![Page 22: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/22.jpg)
NICE
Risks of stopping medication abruptly
Need for prompt treatment due to impact of illness on foetus/child
Increased risk of harm of specific drug treatments
Treatment option that would allow mother to breastfeed
![Page 23: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/23.jpg)
NICE
Prescribing:
Drugs with lowest risk profile
Lowest effective dose
Monotherapy
Risks lower threshold for psychological treatment
Important to put risks from drug treatment in context of the individual woman’s illness
![Page 24: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/24.jpg)
Antidepressants
SSRIs Paroxetine in 1st trimester increase in cardiac malformations (VSD) – planning pregnancy or unplanned advise to stop. Other SSRIs now implicated.
SSRI’s taken after 20 weeks may be associated with an increased risk of persistent pulmonary hypertension of the new born Neonatal withdrawal- normally mild and self limiting
![Page 25: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/25.jpg)

Tricyclics
Tricyclics have lower known risks during pregnancy than other antidepressants
Have higher fatal toxicity index
CHD with clomipramine

![Page 27: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/27.jpg)
Other antidepressants
Venlafaxine – Conflicting results for congenital malformations – data too limited to say safe. Possible increased neonatal withdrawal and increased risk of high blood pressure at higher doses. Theoretical risk of PPHN
Mirtazapine – Possible association with increased rate of spontaneous abortion. No evidence to link to congenital malformations but data too limited to say safe.
JAMA 13 – Metaanalysis – preterm birth 3 days
- Apgar <0.5
- Weight 75g
- Spontaneous abortion not significant.

Atypical Antipsychotics
Olanzapine and Quetiapine
Limited data to base assessment of safety in pregnancy, but available data does not suggest a substantially increased risk of congenital malformations or spontaneous abortions
No pattern of malformations observed.
Withdrawal symptoms
Olanzapine – increased birth weight
![Page 33: Perinatal Mental Health Dr Cressida Manning Consultant Perinatal Psychiatrist Florence House Mother and Baby Unit.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649cb15503460f94976777/html5/thumbnails/33.jpg)
What Clinicians need to do
Do not assume it is always better to stop medication
Provide prompt and Effective treatment of mental illness in pregnancy and postnatal period
Understand, consider and communicate known risks (and how these will be managed) of medication
Complete risk benefit analysis for individual patient.
