Ménière disease (MD) and vestibular migraine (VM) are two distinct disorders that affect the inner ear and balance system. Both conditions can cause dizziness, vertigo, and hearing loss, but there are several key differences between the two.
Ménière disease is a chronic disorder that affects the inner ear, specifically the vestibular system, which helps control balance and spatial orientation. It is characterized by episodes of vertigo, hearing loss, and tinnitus (ringing in the ear). The cause of Ménière disease is not fully understood, but it is thought to be related to abnormal fluid pressure in the inner ear. Ménière disease is a progressive condition and can lead to permanent hearing loss if left untreated. The classic triad of symptoms include vertigo with spontaneous onset and duration of at least 20 minutes and up to 3 hours, fluctuating sensorineural hearing loss, usually unilateral, and ipsilateral tinnitus or aural fullness.
Vestibular migraine, on the other hand, is a type of migraine headache that is accompanied by vestibular symptoms (e.g., vertigo, dizziness, and difficulty with balance) and migraine symptoms (e.g., headache, photophobia, phonophobia, or aura in over half of episodes). It is a commonly misdiagnosed and undiagnosed condition. Vestibular migraines are more common in females and are often triggered by factors such as stress, lack of sleep, and certain foods. 75% of VM patients have a history of migraine. Vestibular migraines typically last for a shorter duration than Ménière disease and do not usually lead to permanent hearing loss.
Diagnosis of Ménière disease and vestibular migraine can be difficult because the symptoms of both conditions overlap. A thorough medical history and physical examination, as well as diagnostic tests such as an audiogram (hearing test) and vestibular function tests, are usually required to distinguish between the two conditions. Sensorineural hearing loss that is present with MD, and not VM, is found by conducting the Rinne and Weber tests.
Treatment for Ménière disease and vestibular migraine also differs. Ménière disease is typically treated with medications to control vertigo and reduce fluid buildup in the inner ear, as well as lifestyle changes such as a low-sodium diet. Vestibular migraines, on the other hand, may be treated with medications to prevent migraines and reduce the frequency and severity of attacks, as well as vestibular rehabilitation therapy to improve balance and reduce dizziness.
Ultimately, while Ménière disease and vestibular migraine both cause similar symptoms, they are distinct conditions with different causes and treatments. New research, however, does suggest a close, bidirectional relationship between the two entities and a concomitant presence is also possible. Patients with MD are more likely to also have VM than the general population and vice versa.
