[Clinico-epidemiologic study of the mental state of a group of elderly persons from the general population].

A clinico-epidemiological study of a representative group of individuals older than 60 years of age from the general city population demonstrated that by far not all mental disorders of old age come into contact with a psychiatrist. A study of 1020 individuals (361 males and 659 females) detected 23 patients (2.3% of the studied population), who suffered from psychotic conditions and who were not registered in the neurophsychiatric dispensary: 6(0.6%) with schizophrenia, 6 (0.6%) -- with delusional psychoses of old age, 9 (0.9%) -- with vascular and senile psychoses and 2 (0.2%) -- with exogenous -- organic psychoses. Besides, in 29 cases (2.8%) there were signs of expressed organic dementia. In 38.9% of the studied individuals there were different mental abnormalities not attaining a psychotic level (initial weakly pronounced and mild psychoorganic conditions).
