M. Albus et al., THE IMPACT OF FAMILIAL LOADING ON GENDER DIFFERENCES IN AGE AT ONSET OF SCHIZOPHRENIA, Acta psychiatrica Scandinavica, 89(2), 1994, pp. 132-134
To evaluate the impact of familial loading and gender on age at onset,
197 schizophrenic patients were investigated. Patients with familial
loading had an earlier age at onset without gender differences. In con
trast, an earlier age at onset for men was found in sporadic cases. Th
ese data support that both gender and familial loading contribute to t
he heterogeneity of schizophrenia.
