On schizophrenia prognosis based on data of a clinicogenetical study.

Peculiarities of the clinical picture of schizophrenia were studied in a group of patients in which less than a half (785) patients had the aggravating fact and in two hereditary-aggravated groups: siblings (109 patients) and parents--children (118 pairs). Prognostic significance of the genetic factor, sex and age was studied as related to peculiarities of the clinical picture of schizophrenia. Hereditary aggravation is shown to be of a decisive importance for schizophrenia prognosis.
