AbstractSeveral studies show that calcium-binding protein S100B is increased in schizophrenia and may be involved in the pathogenesis of tardive dyskinesia (TD). We therefore compared serum S100B levels in normal controls (n=60), schizophrenic patients with (n=32) and without TD (n=50). Assessments included the abnormal involuntary movement scale (AIMS) and the positive and negative syndrome scale (PANSS). Serum S100B levels were measured by enzyme-linked immunosorbent assay (ELISA). The results indicated that patients with TD had higher serum S100B levels than normals and those without TD. Serum S100B levels were positively correlated with AIMS scores in patients with TD. These data suggest that increased S100B levels may be related to neuro-degeneration, associated with TD pathophysiology.Copyright 2009 Elsevier Ltd. All rights reserved.
