The Headache Classification System Published Classification of Headache Disorder
International Classification in Headache Disorder (ICHD)
ICHD-I: 1988
ICHD-II: 2004
Last updated ICHD-III Beta version (Boston 2014) Jes Olesen, MD, PhD University of Copenhagen,
Glostrup Hospital, Denmark

Headache and facial pain vs ENT conditions
ICHD-III Beta: 2013
1. Part 1: the primary headaches
Migraine, Tension typed headache, Cluster headache/TACs
2. Part 2: the secondary headaches
Headache attributed to . (specific causes)
3. Part 3: painful cranial neuropathies
cranial neuralgias
Migraine with cranial autonomic symptoms
Vestibular migraine
11. Headache or facial pain attributed to disorder of the cranium, neck, eyes, ears, nose, sinuses, teeth, mouth or other facial or cervical structure

Migraine introduction
Different phases of Migraine
-
Genetic
Environmental and factor
Cause Pathophysiology of acute migraine
Pathophysiology of episodic and chronic migraine
- Genetic: FHM, TREK!-Trigger factor
Pathophysiology- Aura- vasodilatation- neurogenic inflammation- peripheral and central sensitization- Trigemino vascular systemNeurotransmitter- Serotonergic system- Dopaminergic systemStructural and functional brain change- Brain stem activation
Clinical: chronic and transform migraine, allodynia, neck pain!Anatomical: PAG, central sensitization
episodic
constant
episodic become chronic
acute on chronic
Evolution of Migraine
-
ICHD-III Beta, 2013
-
Tension-type headache
Dull aching, constant, mild to moderate painBilateral location Featureless headache
-
Cluster headache and Trigeminal autonomic cephalalgias (TACs)
Unilateral headache severe Ipsilateral cranial autonomic
symptoms - conjunctival injection/
lacrimation - nasal congestion/
rhinorrhoea - eyelid edema - forehead and facial flushing - Sensation of fullness of ear - Miosis/ptosis
-
Headache with sinus symptoms !
Headache with vestibular symptoms
-
Sinus headache as a misdiagnosis
Sinus headache often self-diagnosed or diagnosed in primary care setting
810 pts with diagnosed as migraine; 78% stated that they were having sinus headache
100 self-diagnosed sinus headache pt.; 86% met criteria for migraine (only 3% had acute sinusitis)
Schreiber CP et al. Arch Intern Med 2004;164:176972.
-
How common of unilateral autonomic (UA) symptoms in migraine
841 subjects had migraine, out of which 226 reported accompanying unilateral autonomic symptoms 26.9%

-
What should we look for? Migraine features:
Pain: throbbing/dull aching
Location: unilateral/bilateral/alternate site
Associated symptoms: photo-/phonophobia, nausea/vomiting
Specific triggers can not be counted as migraine/sinus headache
-
Tension-type headache
Pressure-tightening-constant-frontal pain: mis-diagnosed as sinus headache
Hints: location, sinus symptoms, response to medication
-
The diagnostic criteria for sinus headache
IHS (2004) diagnostic criteria for!
Headache attributed to rhinosinusitis!
A. Frontal headache accompanied by pain in one or more regions of the face, ears or teeth and fulfilling criteria C and D
B. Clinical, nasal endoscopic, CT and/or MRI imaging and/or acute-on-chronic rhino sinusitis
C. Headache and facial pain develop simultaneously with onset or acute exacerbation of rhino sinusitis
D. Headache and/or facial pain resolve within 7 days after remission or successful treatment of acute or acute-on-chronic rhinosinusitis
IHS (1998) diagnostic criteria for!
Acute sinus headache!
A. Purulent discharge in nasal passage either spontaneous or by suction
B. Pathological finding in one or more tests; X-ray, transillumination, CT/MRI
C. Simultaneous onset of headache and sinusitis
D.Headache location; 1. frontal, 2. maxillary, ethmoiditis, sphenoiditis
E. Headache disappears after treatment of acute sinusitis
-
11. Headache or facial pain attributed to disorder of the cranium, neck, eyes, ears, nose, sinuses, teeth, mouth
or other facial or cervical structure
Clinical, nasal endoscopic and/or imaging evidence Temporal relation/waxes and wanes with degree of congestion Exacerbated by pressure applied over paranasal sinus Ipsilateral to unilateral rhinosinusitis
chronic pathology causes persistent headache?: controversy
-
Sino-nasal disorders-headache relation?
Deviation of nasal septum
Hypertrophy of turbinates
Atrophy of sinus membranes
Mucosal contact disease
-
Nasal contact point headache (A11.5.1)
Intermittent pain localised to the periorbital and medial canthal or temporozygomatic regions and fulfilling criteria C and D
Clinical, nasal endoscopic and/or CT imaging evidence of mucosal contact points without acute rhinosinusitis
Evidence that the pain can be attributed to mucosal contact based on at least one of the following:
pain corresponds to gravitational variations in mucosal congestion as the patient moves between upright and recumbent postures
abolition of pain within 5 minutes after diagnostic topical application of local anaesthesia to the middle turbinate using placebo- or other controls1
Pain resolves within 7 days, and does not recur, after surgical removal of mucosal contact points
ICHD-II 2004

Migraine vs Vertigo
-
Fact about migraine and vestibular symptoms
1. Vestibular symptoms as a migraine subcategories; benign paroxysmal vertigo (BPV)
2. Migraine with brainstem aura; vertigo and other brains stem symptoms
3. Most migraine pt. with vestibular symptoms do not have a recognised independent vestibular disorder; Menieres disease, BPPV, vestibular neuritis
4. Many migraine pt. with vestibular symptoms dont have specific diagnosis => emerging vestibular migraine
Eggers SD. Curr Pain Headache Rep 2007;11:217-26Furman JM et al. Lancet Neurol 2013;12:706-15
-
Migraine with brain stem aura !(old term; basilar-type migraine)A. At least two attacks fulfilling criteria B-D
B. Aura consisting of visual, sensory, a/o speech/language, each fully reversible, but no motor or retinal symptoms
C. At least two of the following brainstem symptoms:
1. dysarthria, 2. vertigo, 3. tinnitus, 4, hypacusis, 5. diplopia, 6. ataxia, 7. decreased level of consciousness
D. At least two of the following 4 characteristics:
1. at least one aura symptom spreads gradually over > 5 mins, a/o two or more symptoms occur in succession
2. each individual aura symptoms lasts 5-60 mins
3. at least one aura symptom is unilateral
4. the aura is accompanied or followed within 60 minutes, by headache
E. Not better accounted for by another ICHD-3 diagnosis, and transient ischaemic attack has been excluded

New diagnostic criteria of Vestibular migraine (A1.1.6) : ICHD-III Beta version 2013
A. At least five episodes fulfilling criteria C and D
B. A current or past history of 1.1 Migraine without aura or 1.2 Migraine with aura
C. Vestibular symptoms of moderate or severe intensity, lasting between 5 minutes and 72 hours
D. At least 50% of episodes are associated with at least one of the following three migrainous features:
1. headache with at least two of the following four characteristics: unilateral location, pulsating quality, moderate or severe intensity, aggravation by routine physical activity
2. Photophobia/phonophobia
3. Visual aura
E. Not better accounted for by another ICHD-III diagnosis or by another vestibular disorder

Truth about VM VM may be not associated with migraine headache
Temporal relation of vestibular symptoms - headache is variable
Duration of dizziness/vertigo range from seconds to days
Vestibular symptoms; spontaneous vertigo/gait instability/visual motion sensitivity/dizziness induced by head movement
During an attack-nystagmus is common

-
Otalgia
-
Headache attributed to disorder of ears
No pathology of the ear can cause headache without concomitant otalgia
Primary otalgia+/- headache: structural lesion of pinna, external auditory canal, tympanic membrane or middle ear
most common symptoms of AOM is earache
About 50% of earache is not ear origin (referred otalgia)
-
Sources of referred otalgia 5th CN (mandibular division)
teeth, oral cavity, TMJ
7th CN (nervus intermedius branch)
middle ear
9th CN (Jacobsons nerve)
nasopharynth, eustachian tube, palatine tonsil, tongue
10th CN (Arnolds branch)
hypopharynth, larynth, nasopharynth

Painful cranial neuropathies and other facial pains
-
13.3 Nervus intermedium (facial nerve) neuralgia
Description:
A rare disorder characterized by brief paroxysmal of pain felt deeply in the auditory canal, sometimes radiating to the parieto-occipital region. It may develop without apparent cause or as a complication of Herpes zoster
-
Pain in the throat and mouthGlossopharyngeal neuralgia!
A severe, transient, stabbing, unilateral pain experienced in the ear, base of the tongue, tonsillar fossa and/or beneath the angle of the jaw.
It is commonly provoked by swallowing, talking and/or coughing, and may remit and relapse in the fashion of classical trigeminal neuralgia.
Burning mouth syndrome (BMS); stomatodynia!
an intraoral burning sensation, recurring daily for more than 2 hours per day over more than 3 months, without clinically evident causative lesion

Neck-Tongue Syndrome
-
Vertigo
-
Vertigo: central vs peripheral Time-course-onset: acute, chronic recurrent
Otological symptoms: hearing loss
Neurological symptoms: neuro signs
Ophthalmologic symptoms: nystagmus
Associated symptoms: headache, nausea/vomiting
Triggers: position,
Special test: MRI, Audiogram, nystagmography
-
Acute vestibular syndrome Rapid onset of sustained vertigo, nausea and
vomiting (in association with nystagmus, unsteady gait, and and head motion intolerance)
days to weeks
Classical symptoms
Common-peripheral: vestibular neuritis (VN); labyrinthitis
-
acute central vestibular syndrome (VPN)
Unilateral (fascicular) lesion of the entry zone of the eight nerve, vestibular nucleus lesions, vestibulocerebellar lesions
No sign of other brain stem lesions
-
BPPV vs Pseudo PPV
Features; latency of onset of symptoms after positioning, duration of nystagmus bouts, course of nystagmus during an attack, vertigo
Paroxysmal downbeat, upbeat, or torsional nystagmus -> lesion of central origin

Cortical auditory disorders Cortical deafness
unable to hear sounds but has no apparent damage to the anatomy of the human ear (damage to primary auditory cortex)
Other cortical auditory syndrome:
auditory agnosia;
selective/generalized decrease in recognitive of verbal+/-verbal sound
amusia;
melodies lose their musical character
pure word deafness(auditory verbal agnosia, AVA);
inability to recognize speech(still recognise non-verbal sound)
-
Cortical auditory disorder needs damage bilateral cortical auditory cortex
