Abstract

|
|
This study was to investigate the sex difference in Age at onset of schizophrenia. The age at onset of schizophrenia was determined in SO male and SO female patients who unequivocally met DSM-III criteria for the illness. Three different indexes of onset were used: first treatment, first hospitalization, and the immediate family´s first awareness of psycho-tic symptom and signs. The mean age at onset of the male patients was approximately five years earlier than that of the female patients according to all three critenia. The .onset of psychosis after the age of 35 years occurred in 17% of women and in only 2% of men. The reason for the sex´dif ference is not readily apparent, but it could be a valuable clue to some of the causes of schizophrenia.
