Vestibular Migraine Diagnosis and Characteristics

Core Vestibular Symptoms

Vestibular migraine presents with recurrent episodes of moderate-to-severe vestibular symptoms, including vertigo, unsteadiness, balance disturbance, or motion sensitivity, lasting 5 minutes to 72 hours, accompanied by migraine features in at least 50% of episodes 1, 2, 3
Positional vertigo is triggered by head position changes or visual stimulation 1
Vestibular symptoms are rated moderate when they interfere with but do not prohibit daily activities, and severe if daily activities cannot be continued 1, 2, 3

30% of patients experience episodes lasting minutes, 30% have attacks lasting hours, and 30% have attacks over several days 1, 2, 3
10% of patients have attacks lasting only seconds, occurring repeatedly during head motion or visual stimulation 1, 2, 3
Some patients may take up to four weeks to fully recover from an episode 1, 2, 3

At least one of the following must occur with ≥50% of vestibular episodes: one-sided location, pulsating quality, moderate or severe pain intensity, or aggravation by routine physical activity 1, 2, 3
Photophobia and phonophobia are common accompanying symptoms 1, 2
Visual aura is characterized by bright scintillating lights, zigzag lines, or scotomas that expand over 5-20 minutes and last less than 60 minutes, often restricted to one hemifield 1, 2, 3, 4

Transient auditory symptoms may occur and can mimic Ménière's disease 5
Hearing complaints are typically bilateral and related to sound processing rather than true hearing loss 4
Hearing loss, if present, is mild or absent and stable over time 6

Motion intolerance and susceptibility to motion sickness are common 6, 4
Loss of consciousness is never a symptom of vestibular migraine and should prompt immediate evaluation for alternative diagnoses 5, 4

For definite vestibular migraine diagnosis, patients must have at least 5 episodes meeting the vestibular symptom criteria, current or previous history of migraine with or without aura according to ICHD criteria, and symptoms not better accounted for by another vestibular or headache disorder 1, 2, 3

The American Academy of Otolaryngology-Head and Neck Surgery recommends distinguishing vestibular migraine from other vestibular disorders, such as Ménière's disease, which can be identified by documented low-to-mid-frequency sensorineural hearing loss on audiometry and longer duration of vertigo attacks, and Benign paroxysmal positional vertigo (BPPV), which lacks migraine/headache components and has characteristic nystagmus patterns on Dix-Hallpike maneuver 7
Central causes, such as stroke or multiple sclerosis, must be ruled out, particularly if nystagmus findings suggest neurological causes, and failure to respond to conservative management should raise concern that the underlying diagnosis may not be vestibular migraine 7

Vestibular migraine is defined by vestibular symptoms (vertigo, instability, balance disturbance) lasting from 5 minutes up to 72 hours, with migraine features present in at least 50 % of episodes, according to the American Academy of Otolaryngology‑Head and Neck Surgery. 8

Photophobia and phonophobia are frequent accompanying symptoms in vestibular migraine, as reported by the American Academy of Otolaryngology‑Head and Neck Surgery. 8

When assessing a patient with transient bilateral vision loss, clinicians should first evaluate for migraine characteristics: unilateral pulsatile headache, moderate‑to‑severe intensity, worsening with physical activity, associated nausea/vomiting, and photophobia/phonophobia, per the American Academy of Otolaryngology‑Head and Neck Surgery. 8
True vestibular involvement should be confirmed by the presence of vertigo (spinning sensation), instability, or balance disturbance lasting between 5 minutes and 72 hours, as outlined by the American Academy of Otolaryngology‑Head and Neck Surgery. 8
Vestibular migraine is primarily characterized by vestibular symptoms together with a typical short‑duration visual aura (5–60 minutes), according to the American Academy of Otolaryngology‑Head and Neck Surgery. 8

An aura lasting “several hours” exceeds the usual migraine aura duration of 5–60 minutes, indicating an atypical presentation, as highlighted by the American Academy of Otolaryngology‑Head and Neck Surgery. 9
