[Characteristics of premorbid (pre-manifest) personality traits in schizophrenia in children and adolescents with psychopathic disorders].

The schizoid, hyperthymic and explosive premorbid types were distinguished on the basis of a clinicopsychopathological analysis of the premorbid (++pre-manifest) personality traits in 100 patients with schizophrenia of young age marked by the predominance of psychopathlike disorders. The prevailing schizoid types represent the continuum from schizothymia (sensitive and ++asthenic schizoids) to schizoidia (dissociated and passive types). The data obtained make it possible to attribute the status of the patients of the explosive, hyperthymic, sensitive and, partly, of the ++asthenic types to the evolutive dynamics of the constitution. As for the patients with a passive or dissociated picture of the personality changes, they had already suffered schizophrenic attacks at the first--second age crisis periods.
