Meniere's disease.

How common is it? The quoted prevalence for Meniere’s disease varies 100-fold, but a study in 2010 reported a prevalence of 190 per 100 000 population in the United States. Thus an average primary care practice of 5000 patients would be expected to see 5 to 10 patients with this chronic condition. Meniere’s disease is generally diagnosed in the fourth to sixth decades of life and consequently the incidence of new onset disease is low. General practitioners may encounter a new case only a few times in their career. As full time general practitioners may expect to encounter 10-20 new cases of vertigo each year, it is clear that Meniere’s disease is an uncommon cause of new onset vertigo in primary care.
