/ BACK TO Ménière's disease OVERVIEW

It's estimated that there are 600,000-750,000 cases of Ménière’s disease in the United States, with 45,000 to 60,000 new cases diagnosed annually. Worldwide, Ménière’s disease impacts 12 in 1000 people.

Most cases of Ménière’s disease are unilateral (affecting only one ear), but an estimated 15 to 40 percent of patients are affected in both ears. Ménière’s disease often starts as unilateral and progress to bilateral.

The average age of onset is between 20 and 50 years old. There is no significant difference between the number of men and women affected. The majority of people with Meniere’s disease are 40 years old or above.

The outlook for individuals with Ménière’s disease is positive, despite the fact that a cure does not yet exist. About 90 to 95 percent of patients can control their Ménière’s disease with medical management.
