TY - GEN AU - Kumar, Shashi Ranjan AU - Sinha, Vinod Kumar TI - Gamma activity model for treatment-resistant bipolar psychotic mania PY - 2015/// CY - Mumbai PB - Wolter Kluwer KW - PHARMACOLOGY N2 - The objective was to investigate the effect of clozapine on spontaneous gamma activity in treatment-resistant bipolar psychotic mania. Methods: Patients with treatment-resistant (TR) bipolar psychotic mania on clozapine monotherapy and nontreatment-resistant bipolar psychotic mania patients receiving lithium were prospectively studied for 6 weeks on severity of psychopathology and 30–49 Hz gamma spectral power. Results: Spectral power significantly increased in the lithium group and decreased in the clozapine group; no within group significant difference found. Conclusions: We propose a model highlighting the role of gamma spectral power and modulations of GABAergic neurotransmission in TR bipolar psychotic mania UR - https://journals.lww.com/iphr/fulltext/2015/47020/gamma_activity_model_for_treatment_resistant.18.aspx ER -
