Increased serum S100B in elderly, chronic schizophrenic patients: Negative correlation with deficit symptoms

Elevations of S100B in elderly chronic schizophrenic patients may be related to an active disease process lasting until old-age. Correlations point to the impact of S100B in neuroplasticity and ageing. Post-mortem studies should clarify the presence of altered S100B function in the brain and its relationship to neuroplastic or neurodegenerative processes.
