Abstract

OBJECTIVES: Impaired cognitive functioning is a core feature of schizophrenia. Cognitive impairment in schizophrenia has been associated with white-matter (WM) abnormalities and degenerative changes of cortical myelin in the cerebral cortex. Furthermore, findings suggested a role of the COMT gene in affecting both WM and neuropsychological performances.We thus hypothesized that the COMT ValMet genotype would affect the association between cognitive functions and WM microstructure in a sample of schizophrenic patients. MATERIALS AND METHODS: Seventy-eight schizophrenic patients performed the brief assessment of cognition in schizophrenia for assessment of cognitive performances. Sixty-nine patients provided a venous blood sample for genotypic analysis. WM integrity was evaluated using tract-based spatial statistics with threshold-free cluster enhancement (P
