OCD (obsessive compulsive disorder) shares many features found in other psychiatric
disorders, including the brain changes that occur in individuals exhibiting addictive
behavior. Other studies report biochemical changes such as increased oxidative stress/free radical production, decreased glutathione and glutathione peroxidase, and overall impairment in oxidative status.
Even more dramatically, these alterations have been correlated to the severity of
obsessive-compulsive symptoms. Currently, very few prospective studies
have been carried out demonstrating the effects of raising glutathione in OCD, but
they should be forthcoming.
