We hypothesized that brain regions found to be structurally different in normal men and women(sexual dimorphisms) and abnormal in schizophrenia would show significant sex differences in brain abnormalities, particularly in the cortex, in schizophrenia.
Methods
Forty outpatients diagnosed as having schizophrenia byDSM-III-Rwere systematically sampled to be comparable within sex with48 normal comparison subjects on the basis of age, ethnicity, parental socioeconomic status, and handedness. A comprehensive assessment of the entire brain was based on T1-weighted 3-dimensional images acquired from a 1.5-T magnet.
