Definition/Description[edit | edit source]
Ménière's disease is a disorder that affects the semicircular canals and cochlea (collectively known as the labyrinth) of the inner ear. These canals help to interpret the bodies position in space and help to maintain balance.
This disorder has an unknown cause but is thought to be due to increased fluid pressure in the inner ear. This can cause episodes of vertigo, tinnitus, fullness in the ear and hearing loss.
Prevalence[edit | edit source]
The prevalence of Ménière’s disease is difficult to assess. It appears that that Menieres disease has a prevalence of about 200 cases/100,000 persons in the United States, or in other words, about 0.2 % of the population has Ménière’s disease. The National Institute on Deafness and Other Communication Disorders (NIDCD) estimates that approximately 615,000 individuals in the United States are currently diagnosed with Ménière’s disease and that 45,500 cases are newly diagnosed each year. Ménière’s disease can develop at any age, but it is more likely to happen to adults between 40 and 60 years of age. The prevalence of Ménière disease varies in different geographic regions and ethnic groups, but may possibly be lower by as much as a factor of 10 in some populations. Of these, one-third eventually develops the disease in the second ear as well.
There have been several studies of the US population. In a study performed in Framingham, MA, 1.48 % of the population claimed to have a history of Ménière’s disease. This large prevalence figure likely derives from a tendency of many physicians to lump all cases of recurrent vertigo into the category of Ménière’s disease. Mayo Clinic reported prevalence in 1980 in the Rochester, MN population of 218.2 cases/100,000 people, and an incidence rate of new cases of 15.3/100,000 per year. They also reported a diagnosis rate basically proportional to age up to the age of 60, with a decline thereafter. Ménière’s disease in the ears bilaterally was found in 34% of their cohort.
