Objectives
• Demonstrate the relevance of a primarily neurologic
diagnosis for an otolaryngologist
• Provide guidelines from which to conclude that a
patient likely has vestibular migraine
• Provide a differential diagnosis for diseases with
similar symptomatology

What is VM?
• A manifestation of migraine -- not a distinct entity
• Vestibular center (peripheral or central) disturbedbefore, during, or after migraine

Epidemiology
• Migraines
• Prevalence: 10% of population
• 11-17% of women, 4-6% of men
• 20% of women 30-49 years old
• Dizziness (vertigo and non-vestibular)
• 23-29% of population
• By chance (based on above): 3-4% have both symptoms
•
Using stricter criteria, vertigo w/ migraine ~ 1% population

Pathophysiology of Migraines
Mostly theoretical
Theories include
• Vasospasm
• Cortical Spreading Depression
• Ion Channel Disorderhttp://www.youtube.com/watch?v=yZr9Joe85wg

Pathophys- Vasospasm
http://www.migrelief.com/wp-content/uploads/2012/07/Science-Revised.png
• Historical theory of origin
of pain (trigeminal
innervation of meninges)
•
Linked to auras as well(hypoxia)
VM Theory
Vasospasm of AICA
transmitted to internal
auditory artery

Cortical Spreading Depression
• Proposed
mechanism for
auras and pain
• Vestibular
processing
centers affected
may causevertigo (central)

Pathophys: Ion Channels
• Propranolol (BB) , Verapamil (CCB)
• Mutations of CACNA1A (Ca channel)
found in familial hemiplegic migraine(FHM1) and episodic ataxia type 2 (EA-2)
• Could classic migraine or vestibular migraine have a
defective Calcium channel?
• Link not found yet

What is “Dizziness”
• Vertigo = sensation of spinning or circular movement
• Oscillopsia
• Light-headedness
• Mental fog/lack of clarity
• Imbalance
• Causes: vestibular, psychogenic,
cardiac (orthostatic), CNS origin (TIA),drug related, psychogenic

VM Symptoms- Vertigo
• Duration: seconds to weeks (commonly minutes to hours)
• Most often spontaneous (i.e. non-positional), but can be positional or due
to head motion intolerance *
• Rotational
• May be caused by visual stimuli (car chase scenes, repeating patterns onrugs)
• Definition of giddiness: adj; affected with vertigo, dizzy; Also, frivolous and
lighthearted

Vertigo Duration
Most common, based on Neuhauser et al. (2001)
- Seconds to minutes: 18%
- 5-60 minutes: 33%
- 1-24 hrs: 21%
- >24hrs: 2%
- From 33 patients deemed to meet “definite VM” criteria

Testing
• Specific exam tests: Dix-Hallpike, Vestibulo-ocular reflex, Romberg
• Battery of other tests: audiogram, ABR, VEMP, video-oculography/VNG, water calorics
• Some relevant findings on nystagmography
• MRI when still unsure
• Goal: primarily rule out other
identifiable causes of vertigo
-

24/50
Testing- Nystagmus
Video-oculography of 20 VM patients (von Brevern et. al 2005)
• Found pathological spontaneous and positional nystagmus in 70% of pts during acute VM attack
• Spontaneous (central origin) or positional (peripheral origin)
• 70% also had positive Romberg
*No hearing loss noted

Diagnosis of VM
• No official agreed upon criteria
• Difficult: no pathognomonic exam signs, no
biomarkers, no lab tests, lots of symptom overlap
• Only diagnostic criteria that includes “vertigo” as a
symptom is the International Headache Society’s
criteria for basilar type migraine• Important to try to rule out other causes of vertigo

Basilar migraine
• What it is:
• Subtype of migraine (usuallyoccipital pain)
•Sx’s = vertigo (60%), ataxia, parasthesias, dysarthria
• Why it’s not VM:
• BM diagnosis criteria requires at least two posteriorcirculation symptoms, lasting 5-60 minutes, and
immediately followed by a migraine

IHS II- Basilar migraine
Diagnostic criteria:
A. At least 2 attacks fulfilling criteria B-D
B. Aura consisting of at least two of the following fully reversible symptoms, but no motor weakness:
1. dysarthria
2. vertigo
3. tinnitus
4. hypacusia5. diplopia
6. visual symptoms simultaneously in both temporal and nasal fields of both eyes
7. ataxia
8. decreased level of consciousness
9. simultaneously bilateral paraesthesias
C. At least one of the following:
1. at least one aura symptom develops gradually over ≥5 minutes and/or different aurasymptoms occur in succession over ≥5 minutes
2. each aura symptom lasts ≥5 and ≤60 minutes
D. Headache fulfilling criteria B-D for 1.1 Migraine without aura begins during the aura or follows aura
within 60 minutes
E. Not attributed to another disorder 1 http://ihs-classification.org/en/02_klassifikation/02_teil1/01.02.06_migraine.html

Meniere’s Disease
• What is it:
• Vertigo episodes lasting 20 min to 24 hrs with often
unilateral hearing sx’s including tinnitus and hearingfluctuation/loss (low frequency)
• Why it’s not VM:
• Hearing loss is possible with VM, but typically does notprogress to profound.
• Permanence of hearing loss
-

VM vs Meniere’s: Reality
• Significant overlap, making diagnosis difficult
• Prevelance of migraine in Meniere’s patient
•Migraine symptoms like aura up to 45% Meniere’spatients experience during vertigo (Radke et al. 2002)
• Lempert et al. (2013) if criteria for Meniere’s met
(audiogram), should diagnose as Meniere’s (notVM)
-
8/9/2019 Vestibular Migrain
34/50
BPPV
• What it is:
• Peripheral vertigo due to canaliths
misplaced in the semicircular canals
•Why it’s not VM:• Often Dix-Hallpike is normal in VM
• Vertigo is shorter duration and more frequent episodes
• VM has earlier onset in life
• Positional nystagmus is persistent (no fatigue)

How Can We Treat It?
-
8/9/2019 Vestibular Migrain
36/50
Treatment
• Classic migraine treatment
• Abortive methods
•
Prophylaxis• Symptomatic (e.g N/V)
• Trigger avoidance
• Vestibular migraine-specific treatment
• Physical therapy
• Limited drug trials (zolmitriptan, topiramate)
-
8/9/2019 Vestibular Migrain
37/50
Treat- Abortive
• Triptans (sumatriptan, rizatriptan)
• Zolmitriptan vs placebo in treating specifically VM in
10 patients
inconclusive (Neuhauser et al. 2003)
• Combo pills:
• Fioricet (butalbital, acetaminophen, caffeine)
• Fiorinal (butalbital, aspirin, caffeine)
-
8/9/2019 Vestibular Migrain
38/50
Treat- Prophylaxis
• Antihypertensives: BB’s ( propranolol, metoprolol,
atenolol), CCB’s (verapamil)
• Antidepressants: TCAs (nortriptyline)
• Anticonvulsants: topiramate, lamotrigine
-

Treat- Symptoms
Nausea--> suppress the vestibular system
• promethazine, ondansetron (antiemetics)
• dimenhydrinate, meclizine (antihistamines)
• benzodiazepines (short course)
• metoclopramide *
Phono/photophobia removal of stimuli

40/50
Treat- Triggers
• Avoidance is the key!
• Symptom diary
• Dietary modifications• Avoid: caffeine, alcohol
• Situational/environmental
• Hormonal: menstrual cycles
•
Weather changes• Lack of sleep, dehydration, stress

Treat- Physical Therapy
• Found to be effective specifically for VM
Whitney et al. (2000); retrospective case series of 39 pts
• Initial vestibular functioning testing before rehab
• Treated with vestibular rehab (strength/stretching, habituation,
balance/gait training)
• Completed questionnaires pre- and post treatment (symptomseverity rating 0-100, dizziness handicap inventory, dynamic
gait index, # of falls)
-

Treat- PT
Results: Pre-treatment
- 81% patients presented with abnormal vestibular
testing in at least one vestibular test
-
8/9/2019 Vestibular Migrain
45/50
Treatment- PT
Results
- Statistically significant improvements in almost all categories of physical
performance/perceived abilities
- # of patients report more than one fall in past four weeks decreased by 78%
- Severity rating (0-100): 15 pts rated symptoms as less severe at discharge, 6
rated higher, 1 unchanged, and 11 w/ baseline score of 0 that did not increase
by discharge
-

Treatment- PT
Conclusion- Offer vestibular rehab to patients with VM
- 35/39 patient had improved scores

Summary- VM
• Common manifestation of migraine and common
cause of vertigo
• Still not well defined as a specific disease process
• No consensus on diagnosis
• Treatment mostly for migraine (triggers, abortive
and prophylactic meds, physical therapy)
-
8/9/2019 Vestibular Migrain
48/50
What Happens Next
• Need accepted diagnostic criteria
• Will require better pathophys understanding
•
2014
criteria for VM supposed to be published in theIHS’s International Classification of Headache
Disorders
• Without better understanding of disease, may be
inappropriate to establish criteria to diagnose as astand-alone disease process
