Summary

The results of the study "schizophrenia, related disorders and glutathione" conducted at the Laboratory of Psychiatric Neuroscience (LUNEP) DUPA of Lausanne, reinforce the hypothesis proposed that a deficit intracerebral glutathione is a vulnerability factor for Schizophrenia at least for a subgroup of patients. While pursuing the baseline study, it is appropriate now to try to restore a higher level of glutathione in patients to see if this increase is accompanied by an improvement in symptoms, particularly negative symptoms and disorders cognitive, particularly resistant to current therapy. N-acetyl-cystein (NAC) is a precursor of glutathione which is used clinically for various indications, well tolerated even at high doses. The investigators propose a double-blind cross-over with the aim to study if the N-acetyl-cystein (at a dose of oral 2g/day) leads on the one hand a rising glutathione brain (measured in resonance magnetic spectroscopic) and also improved patients' conditions (determined by clinical assessments, psychopathological, neuropsychological, biochemical and physiological), while recording any side effects. As a first step, this study should include at least thirty patients and last for two to three years. It is important to note that this is not a study of medication suggested by a pharmaceutical industry, but a medical search.

Once included, the patients will be randomly placed in two groups: one group (1) will receive 2 g/day of NAC (2caps of 0.5g twice a day) and the other group (2) a placebo, for a duration of 8 weeks. At the end of the 8 weeks, group (2) will receive NAC and (1) the placebo for another 8 weeks
