Tardive dyskinesia (TD), the most severe side effect of antipsychotics, is characterized by late-onset, repetitive involuntary choreiform movement, tics and grimaces of the orofacial muscles, and dyskinesia of the distal limbs. Pervious studies have suggested that schizophrenic patients with TD had an excess of neurodevelopmental disturbance, particularly minor physical anomalies, in association with cognitive dysfunction and abnormalities of cerebral structure. In this research, voxel-wised DTI analysis was performed to investigate the differences among schizophrenia with/without TD and healthy controls. Relationship between clinical symptom and WM microstructure abnormality were also examined.
