Research Abstract

Impaired social cognition in schizophrenia is considered as the core contributor in the poor psychosocial functioning of schizophrenia patients. Using structural and functional MRI, we investigated neural bases of social cognitive impairments in schizophrenia. As results, morphological and functional abnormalities in frontal, temporal, and parietal cortices as well as white matter abnormalities were found to be associated with various facets of social cognitive impairments in schizophrenia. These results give us an insight into optimal cognitive rehabilitation in schizophrenia.
