ABSTRACT
The treatment of mental illnesses that are resistant to conservative therapy poses a serious problem. Surgical methods with proven efficacy have been proposed for only a small group of psychiatric diseases, while in practice non-classical clinical situations are seen rather often. A 36-year-old man with a 18-year history of "schizophrenia with a predominant obsessive-compulsive syndrome" was referred to the Burdenko National Medical Research Center of Neurosurgery for consideration of neurosurgical treatment. Based on results of longitudinal independent evaluations of the patient in several specialized clinical centers the disease was considered resistant to medical therapy. Radiosurgical procedure was performed by means of Leksell Gamma Knife Perfexion™ (Elekta AB; Stockholm, Sweden). Ventral portion of the anterior limb of internal capsule was targeted with two 4-mm isocenters on each side, with prescription dose at 50% isodose line of 80 Gy and a maximal dose of 160 Gy. No obvious complications or side effects were noted during 13-month follow-up after radiosurgery. Gradual clinical improvement was observed with 25% reduction of the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score at 13 months after treatment. Similarly, the Hospital Anxiety and Depression Scale (HADS) anxiety and depression scores decreased by 24% and 58%, respectively. This is the first published case of radiosurgical treatment of a psychiatric disorder in Russia. It demonstrates the potential efficacy of Gamma Knife capsulotomy for non-classical forms of obsessive-compulsive disorder comorbid with schizophrenia. Nevertheless, definitive conclusions about the reliability of this radiosurgical indication can only be made based on the results of larger studies.
