Three hundred and twenty-three patients with Meniere's disease were registered to have an intractable disease from 779 members or clinics of the Toyama Medical Association in Toyama Prefecture in 1974 and 1979. Of the 1, 044 patients who had visited the Neuro-Otological Clinic of the Toyama Medical and Pharmaceutical University Hospital during the three years from October 1979 to December 1982, 102 patients were diagnosed to have Meniere's disease including atypical cases. An epidemiological study of these patients were made and the following characteristic epidemiological features were obtained.1) The incidence of Meniere's disease in Toyama Prefecture was estimated to be 14.7 per 100, 000 population on the basis of the registration of this intractable disease made by the members of the Toyama Medical Association.2) Sex-ratio: The incidence was higher in males than females in Toyama Prefecture.3) Age-distribution: The age distribution of the 102 patients with Meniere's disease peaks at the age group of 40-49 years for males and females.4) There was an increasing number of patients in the cities of Toyama Prefecture compared with the countryside. This tendancy was seen in the patients collected by the Toyama Medical Association.5) Season of onset: There was an apparent high incidence of initial vertiginous attack in March and in October. This tendency was seen in patients from Toyama Medical and Pharmacutical University Hospital.6) The incidence of bilateral Meniere's disease: Of the 102 patients with Meniere's disease (including atypical cases), 9 were bilateral (8.9%).
