[Comparative study of the prevalence and types of neuropsychiatric disorders in late middle-aged persons in urban and rural homes for the aged].

The authors studied psychic disorders in urban and rural people over 60 years of age living in old people's houses. The differences in the character of the neuropsychic disorders consisted in a prevalence of epilepsy, mental retardation, and organic disorders of various origin in old country people, and of neurotic disturbances in urban people. Equally prevalent among the inhabitants of urban and rural old people's houses were schizophrenia, manic-depressive psychosis, involutional and somatogenic psychoses, alcoholism, as well as senile and atherosclerotic dementia.
