title: [Epidemiology of spinocerebellar degeneration in Tottori prefecture].
abstract: 1. A prevalence study of spinocerebellar degeneration (SCD) was carried out in Tottori prefecture. Seventy two patients were found and the prevalence rate was 11.6 per 100,000 population. When age adjusted to the country's population, the figure was 10.2. These rates was higher than those reported previously in Japan. The prevalence ratio for male and female was 1.4:1. 2. Twenty four cases of SCD who died were analysed for the study of long prognosis. The average age at death was 60.7 +/- 9.8 and the mean duration of illness was 5.3 +/- 2.8 years. The leading causes of death were bronchopneumonia in seven cases, feebleness in four cases, sudden death in four cases, malignant neoplasms in three cases and suffocation in two cases.
