It has been suggested that oxidative stress plays a role in the pathogenesis of Schizophrenia. This study provides support for the hypothesis that in vivo levels of gluthathione, the major antioxidant in the brain, are altered in the anterior cingulate cortex and dorsolateral prefrontal cortex of patients with Schizophrenia. Further studies are still needed to determine underlying mechanisms, including the effects of treatment, and to investigate the relationship between GSH levels, other markers of oxidative stress, and severity of both positive and negative symptoms.
