[Premorbid personality traits and features of the onset of schizophrenia in families with a hereditary predisposition].

The report covers a group of schizophrenic parents and their children (219 patients from 101 families); the author studied variants of premorbid personality traits, the patient's age at the onset of the disease, the duration of the initial period, its syndromes in the descending generation. Comparing signs in the pairs of parents-children the author detected the most stable signs in transmission to the descending generations. The following signs were attributed to such stable traits: schizoid personality traits, a short initial period, a psychopathlike syndrome in the initial period. Special tables were formed permitting to prognosticate the appearance of some signs in children when some signs were known in parents.
