Oxidative Stress

OXIDATIVE STRESS AS MARKER OF POSITIVE SYMPTOMS OF SCHIZOPHRENIA - supports the use of Antioxidants in recovery protocol

"Our study also demonstrates a reduction in superoxide dismutase activity and an increase in protein carbonyl concentration in the CSF of tardive dyskinesia patients. Although they did not pass the statistical test, it is important to discuss the findings in the context of the oxidative stress hypothesis of tardive dyskinesia. Superoxide dismutase is an enzyme critical in the of superoxide, a normal byproduct of oxidative metabolism (32). Attenuated activity of superoxide dismutase may contribute to the increase of oxidized protein."(2.)

" The hypothesis of oxidative damage to striatal neurons mediated by neuroleptic enhancement of glutamatergic neurotransmission is supported by reports that vitamin E reverses the symptoms of tardive dyskinesia; the anecdotal reports have been sustained by double-blind, placebo-controlled studies with vitamin E (43-45). Notably, patients are more responsive to treatment with vitamin E earlier in the course of their disorder, consistent with the model that the oxidative damage is cumulative over time and would involve functional impairment before frank degeneration."(2.)
