Meniere's disease and vestibular migraine are the two most commonly confused vertigo diagnoses in adults. They share core symptoms — rotational vertigo, nausea, light and sound sensitivity, imbalance — and they are often mistaken for one another for years before the correct diagnosis lands. Getting the label right matters because the treatment pathways diverge sharply: sodium restriction and diuretics for one, migraine prophylaxis and trigger control for the other.
This is a plain-language comparison of how the two conditions differ, what overlap looks like, and what a patient can reasonably track at home to help their clinician distinguish between them.
The short version
- Meniere's disease is primarily a disorder of the inner ear. Attacks come with hearing change, tinnitus, and ear fullness in the affected ear, and last 20 minutes to several hours.
- Vestibular migraine is primarily a neurological disorder. Attacks are often associated with headache, light or sound sensitivity, visual aura, or motion intolerance, and last anywhere from 5 minutes to 72 hours.
- About 20–30% of patients meet criteria for both, which is why the distinction is harder than textbooks make it sound.
Attack duration
Duration is the single most useful data point you can bring to your appointment. For a deeper breakdown of the Meniere's duration window and the phases of a typical attack, see how long a Meniere's attack lasts.
- Meniere's: diagnostic criteria require spontaneous vertigo episodes of 20 minutes to 12 hours. Shorter than 20 minutes and it is unlikely to be Meniere's; longer than 24 hours and something else is usually going on.
- Vestibular migraine: episodes can be as short as 5 minutes and as long as 72 hours, and they are much more variable in length from one attack to the next within the same patient.
Hearing symptoms
The inner-ear involvement is what tips the balance toward Meniere's.
- Meniere's: documented low-to-mid frequency sensorineural hearing loss on audiometry during or near attacks, tinnitus that is often low-pitched or "rumbling," and a clear sense of fullness or pressure in one ear.
- Vestibular migraine: hearing usually stays normal. Some patients report transient tinnitus or mild fullness, but permanent hearing loss is not part of the diagnosis.
If a patient has serial audiograms that show a fluctuating low-frequency loss in one ear, that pattern is highly suggestive of Meniere's and very uncommon in pure vestibular migraine.
Headache and migraine features
Many people with Meniere's also get headaches, so "I get headaches" is not a disqualifier. What matters is the pattern.
- Vestibular migraine requires (per Bárány Society / IHS criteria) a current or past history of migraine, plus at least half of vertigo episodes accompanied by migraine features — headache, photophobia, phonophobia, or visual aura.
- Meniere's can coexist with occasional headaches but the headaches are not time-locked to vertigo attacks in a systematic way.
Triggers
Trigger profiles overlap a lot, but the emphasis is different.
- Meniere's responds most clearly to sodium, dehydration, and sometimes caffeine and alcohol. Barometric pressure shows a modest population-level signal.
- Vestibular migraine responds to classical migraine triggers: poor sleep, skipped meals, aged cheese, red wine, chocolate, MSG, bright or flickering light, strong smells, and hormonal cycles.
If sodium restriction changes nothing over 6–8 weeks but removing a migraine trigger (e.g., standardizing sleep, cutting aged cheese) cuts attack frequency in half, that is diagnostic information.
Frequency and natural history
- Meniere's often clusters: periods of several attacks a month followed by months of remission. Hearing loss accumulates over years.
- Vestibular migraine is more diffuse, often with chronic between-attack motion sensitivity, visual sensitivity in busy environments, and brain fog that can last days.
What to track to help your clinician
- Duration of each vertigo episode in minutes or hours.
- Whether hearing, tinnitus, or ear fullness changed during the episode, and in which ear.
- Whether a headache occurred before, during, or after — with photophobia or phonophobia noted.
- Sleep the night before the attack.
- Suspected food triggers eaten in the prior 24 hours.
- Menstrual cycle phase, if applicable.
- Barometric pressure at attack time (hard to capture by hand — an app that records local pressure automatically does this for you).
Why the distinction matters for treatment
- Meniere's first-line treatment is typically low-sodium diet, diuretics, vestibular rehabilitation, and in refractory cases intratympanic steroids, gentamicin, or surgery.
- Vestibular migraine first-line treatment is migraine prophylaxis: sleep regularity, trigger avoidance, and medications like nortriptyline, topiramate, or propranolol — not a low-sodium diet.
Giving a vestibular migraine patient a diuretic and a 1500 mg sodium cap for a year will not help them. Giving a Meniere's patient a migraine prophylactic instead of addressing inner-ear pressure will not help them either. The label determines the lever you pull.
The pragmatic bottom line
Duration, hearing involvement, and migraine features do most of the diagnostic work. Thirty days of structured logging — attack duration, hearing change, headache, sleep, food, pressure — is usually enough to let a specialist pick the right label confidently, or to recognize that both labels apply.
The free Pattern Handbook walks through the logging method on paper. The iOS app captures duration, symptoms, triggers, and local barometric pressure automatically on every entry, and exports a clinician-ready one-page summary for your next ENT or neurology visit.
