S165. GLUTAMATERGIC ABNORMALITIES IN EARLY SCHIZOPHRENIA AND BIPOLAR DISORDER MEASURED USING WHOLE-BRAIN SPECTROSCOPY

Background Glutamatergic abnormalities in schizophrenia and bipolar disorder gave been identified using proton magnetic resonance spectroscopy (1H-MRS). Although schizophrenia and bipolar disorder are both known to involve extensive brain networks, most MRS studies have been done using single-voxel techniques. In this study we used whole brain 1H-MRS to examine glutamine-plus-glutamate (Glx) in early schizophrenia and bipolar disorder to examine...
