A typological model of schizophrenia based on age at onset, sex and familial morbidity.

Acta psychiatrica Scandinavica - 1 Feb 1994

Abstract excerpt

We investigated the age at onset distributions of schizophrenia in men and women and the relationship of age at onset and sex to the familial rates of schizophrenia and manic-depression in data from a Swedish family study of 270 schizophrenic probands. On the logarithmic scale, the age at onset distribution of schizophrenia in both male and female relatives was bimodal, suggesting that broadly defined...
