Ménière's disease

Ménière's disease (MD) is a disease of the inner ear characterized by potentially severe and incapacitating episodes of vertigo, tinnitus, hearing loss, and a feeling of fullness in the ear. Typically, only one ear is affected initially, but over time, both ears may become involved. Episodes generally last from 20 minutes to a few hours, with varying time between episodes. The hearing loss and ringing in the ears can become constant over time. Ménière's disease was identified in the mid-1800s by Prosper Menière.
