Relationship between presumed etiological factors and clinical picture in 100 schizophrenic males.

The schizophrenic syndrome, in one form or another is a result of combinations of genetic, organic and psychosocial factors. 100 schizophrenic males were studied and etiological factors such as schizophrenia or affective illness in direct relatives, brain damage or temporal lobe epilepsy, an over-protective parent or latent homosexuality were isolated. The findings show a relationship between these etiological factors and the clinical picture and course and an attempt is made to use the etiological factor in classifying schizophrenia.
