title: Epidemiology of Parkinson's disease in Benghazi, North-East Libya.
abstract: An epidemiological study of Parkinsonism was carried out in Benghazi situated in North-Eastern Libya. On the prevalence day, January 1, 1985, a total of 163 patients with Parkinson's disease were found living in the investigated area, which had a population of 518,745. The crude prevalence rate was 31.4 per 100,000 population and the incidence rate was 4.5 per 100,000 population per year. The average age at death was 71.2 years and the mean duration of the illness was 6.7 years. Our findings suggest that the risk of Parkinson's disease observed in the present study is intermediate to that reported among the white and black races and comparable with the yellow race and the Sardinians.
