Deep brain stimulation (DBS) is a form of neurosurgical treatment of neurological and psychiatric patients that consists of the insertion of electrodes into precisely defined neuroanthomic structures and chronic electrostimulation from neurostimulators. The aim of the thesis is to present the results from individual meta-analyzes, various clinical studies and case reports for all possible indications of DBS in psychiatry such as obsessive-compulsive disorder (OCD), depressive disorder, Tourette's syndrome (TS), anorexia nervosa ( AN), addiction, anxiety disorders, autism and schizophrenia. Unfortunately, psychosurgery is still prohibited in Croatia due to the law on the "Protection of Persons with Mental Disorders" (OG 76/14, Article 16), which was taken over from the previous Yugoslav law. As these are particularly sensitive and vulnerable patients and in the field of surgery with a not so bright history, exceptional responsibility is needed in selecting, including, obtaining consent and monitoring patients, adhering to important ethical rules and following clearly set guidelines. Complications reported in DBS for psychiatric indications appear to be similar to those reported for DBS in movement disorders, and most reported adverse reactions appear to be transient or resolved by changes in stimulation settings. In the last decade, more than 200 DBS neurostimulators have been successfully implanted in Croatia in patients suffering from Parkinson's disease, dystonia, torticollis, essential tremor and Gilles de la Tourette's, which can also be understood as a disorder of involuntary movements. Therefore, there are certainly technical and personnel possibilities for performing DBS in patients suffering from psychiatric illnesses that no other form of therapy can help, but unfortunately this is not possible as long as the existing law is in force.
