Background
In 1861, French physician Prosper Ménière described the condition that now bears his name. Historically, accountants, dentists, otolaryngologists, and watchmakers - people who do fine, meticulous work that requires great concentration and control of the hands for long periods of time_are more prone than others to develop this condition. In fact, it was originally called watch-maker's disease.
Incidence
In 75 percent of the cases, Ménière's disease is confined to one ear, while in the other 25 percent, both ears are involved. The attacks vary considerably from one patient to another and from episode to episode. The average attack lasts two to four hours. After a severe attack, most people find that they are extremely exhausted and must sleep for several hours. In some people, Ménière's episodes may occur in clusters; that is, several attacks may occur within a short time. In other cases, weeks, months, or even years may pass between episodes.
