[Family background characteristics in slowly-progressive schizophrenia].

The authors studied the family history of 103 patients with slowly progressive schizophrenia (1218 relatives) characterized by the predominance of obsessions and hysterical disturbances. The study disclosed the accumulation of both various forms of schizophrenia and personality anomalies of psychoasthenic and hysterical types among the relatives of the patients. The clinical specific features of "linear" symptomatology in the families studied were considered. The role of one or another type of constitutional predisposition in the development of phenotypical variants of the disease is shown.
