dc.description.abstract | Dysfunctional social-emotional perception in patients with schizophrenia can result in adverse clinical symptoms and poorer long-term outcomes. The white matter tracts that interact among a number of brain regions have an important role to play. However, few neuroimaging studies focus on the effects of white matter connectivity on social-emotional perception in schizophrenia and its impact on patients' clinical symptoms and long-term out-comes. Forty-one patients with schizophrenia spectrum psychosis and 42 healthy controls underwent structural magnetic resonance imaging. The white matter fractional anisotropy values of the emotion recognition areas, the bilateral anterior thalamic radiation, inferior longitudinal fasciculus, cingulum bundle, superior longitudinal fasciculus, and uncinate fasciculus were compared between patients with schizophrenia spectrum psychosis and healthy controls. Social-emotional perception levels and symptom severity at baseline and after 1 year were examined. A group analysis showed that white matter connectivity was significantly lower in the bilateral anterior thalamic radiation, cingulum bundle, right inferior longitudinal fasciculus, and uncinate fasciculus of patients with schizophrenia spectrum psychosis compared to the healthy controls. Contrastingly, a correlation analysis revealed that larger right uncinate fasciculus fractional anisotropy values were associated with lower social emotional perception levels in patients with schizophrenia spectrum psychosis. Additionally, the white matter fractional anisotropy values of the right uncinate fasciculus showed a significant positive correlation with the severity of positive symptoms at baseline and with poor outcomes after 1 year. The findings of the present study suggest that impaired social-emotional perception in patients with schizophrenia spectrum psychosis is associated with larger white matter connectivity of the uncinate fasciculus, which is also associated with more severe symptoms at baseline and after 1-year. These results suggest that the uncinate fasciculus could affect the pathophysiology of schizophrenia. | - |
