Psychiatric disorders result in great suffering of affected patients, who often have rather limited treatment options. In cases refractory to standard medical and behavioral therapy, interventional procedures may be the only feasible solution. The authors experience with Gamma Knife bilateral cingulotomy for treatment-resistant major depression disorder (5 cases) and anorexia nervosa (6 cases), and bilateral anterior capsulotomy for severe obsessive-compulsive disorder (10 cases) shows that such radiosurgical techniques may be applied both effectively and safely. During post-treatment follow-up, the vast majority of patients demonstrated gradual reduction of psychiatric symptoms and improvement of the quality of life, which was confirmed by results of regular neuropsychological testing and imaging examinations. No major side effect was observed in any case. More active application of radiosurgery (using standardized technique) for management of mental illnesses in various Gamma Knife centers worldwide should be encouraged.
