| Research Abstract |
We examined recent onset schizophrenic patients and ultra high risk subjects by using two neurophysiological methods to evaluate dysfunction of GABA and NMDA systems which is assumed to be related with pathophysiology of schizophrenia. The resent onset schizophrenic patients showed dysfunction of GABA system, and this dysfunction was correlated with working memory disturbance. The results suggest GABA-modulating interventions in the early course of schizophrenia. The ultra high risk subjects showed dysfunction of NMDA system as well as schizophrenic patients. The results support the hypothesis that dysfunction of NMDA system is involved in decrease of gray matter volume even before clinical onset of schizophrenia.
