[Demyelinating diseases in the southern regions of Uzbekistan].

Examination of the clinical archives for 1931-1980, epidemiological survey of the Samarkand and Kashka-Darya regions as well as clinical examination of 49 patients showed disseminated sclerosis to occur more rarely among the aboriginal population (26,8%) than among newcomers (73,2%). General morbidity was 1.7: 100.000 population; this made it possible to attribute the region under study to a low risk zone. The debut, clinical picture and clinical course of disseminated sclerosis in three groups of patients (aboriginal population, persons born in other Uzbekistan regions and newcomers) were similar and did not differ from classical descriptions by European authors.
