A review of early identification and conversion studies of event-related potentials in individuals with high risk of schizophrenia
There is a clinical high-risk period(CHR)before the onset of schizophrenia.Early detection and early treatment are crucial for the prognosis of the disease.Event-related potential(ERP)is a special brain evoked potential.Different ERP components can reflect the neuroelectrophysiological changes of the brain in different cog-nitive processes.Exploring the ERP components of CHR abnormalities may have an important role in the early rec-ognition of diseases and transformation risk.This review found that P300 and MMN have predictive effects on the risk of mental illness conversion,while other ERP components such as P50,Pl.and N400 require more research to verify their reliability as risk markers for mental illness conversion in high-risk populations.
