ABSTRACT
Objective:To explore the relation of cognitive function correlates to P50 sensory gating in patients with schizophrenia.Methods:Totally 106 patients with drug-na¨ive first-episode schizophrenia and 86 healthy con-trol subjects matched for age,sex and education were recruited.All patients met the Diagnostic and Statistical Man-ual of Mental Disorders,Fourth Edition (DSM-IV)criteria for schizophrenia.Their cognitive function were assessed with the MATRICS Consensus Cognitive Battery (MCCB).The P50 auditory gating potential were recorded in all subjects using conditioning-testing stimulus paradigm and stimulus train paradigm.The P50 components were meas-ured in S1 S2 latency,S1 S2 amplitude and P50 suppression ratios.Results:Compared with the controls subjects, the patients with schizophrenia had significantly longer S1[60.8 ±7.8)ms vs.(56.3 ±7.0)ms,P 0.05).No significant correlation was found between P50 gating measures (P50 ratio and P50 ampli-tude difference)and neuropsychological measures in MCCB scores (Ps >0.05).Conclusion:There may be no as-sociation between P50 deficits and cognitive measures in patients with drug-na¨ive first-episode schizophrenia.
