[The sex factor and mental disorders of advanced age].

With the aid of a clinico-statistical method the authors studied 1514 patients older than 60 years. The following facts were found. There was prevalence of females in schizophrenia, circular psychoses, neurosis, atherosclerosis and senile dementia. Depressive syndromes were more often seen in females, subaffective and paranoid--in males (these syndromes were most linked with sex). In aging schizophrenic patients there waa a significant increase of hallucinatory-delusional syndromes (both in males and females), depressions in females, a tendency towards a drop in the frequency of depression in males. The linkage of syndromes with sex decreased along with aging.
