There is ample evidence that inflammatory processes play a role in the pathophysiology of schizophrenia. Randomized controlled trials have shown benefit of some (but not all) anti-inflammatory drugs on symptom severity. So far, these drugs have been given for a relatively short period. Simvastatin combines well-established vascular protection with reduction of the inflammatory status of the brain, thus offering an attractive potential to further improve treatment of schizophrenia and related disorders.
