[Deep brain stimulation for psychiatric disorders].

Deep brain stimulation (DBS) is a treatment using implanted electrodes to deliver electrical pulses to targeted areas of the brain. DBS holds great promise in psychiatry for the treatment of patients with treatment-resistant obsessive-compulsive disorder, depression and Gilles de la Tourette syndrome. Double-blind and open trials have shown that the treatment is effective in about half of these patients. Further research should focus on optimizing DBS with respect to target location for the various psychiatric disorders. More controlled double-blind trials are needed to corroborate the effectiveness of DBS in patients with psychiatric disorders.
