Analyzing the data on primary elderly and senile patients (60 years or more) presenting psychic disorders which were collected by all psychiatric institutions of Moscow during a year, the incidence of all recorded psychic diseases, psychic disturbances of psychotic and nonpsychotic nature as well as individual diseases in the old population was ascertained. The authors show age-related specificity of the nosological structure of gerontopsychiatric morbidity and the differences in the nosological distribution of patients in relation to their sex and age. It was also shown that psychoses and metal deterioration in the elderly and the old are recorded by psychiatric institutions 2.8 times as often as disorders of nonpsychotic character. It was established that intensive indices of the incidence of recorded psychotic disturbances increase with the aging of the population whereas the indices of the recorded prevalence of nonpsychotic disturbances, in contrast, decrease. Distinctive differences in the incidence of particular forms of psychic pathology with regard to the patients' sex are demonstrated. The condition of psychiatric care for the elderly and senile community is evaluated.
