ABSTRACT
Long-term results (5-20 years) recorded in 304 patients operated on stereotactically for psychopathologic disorders are presented. The largest group of 260 surgically treated subjects represented aggressive patients. This group consisted of 150 patients with mental retardation, 70 with epilepsy, 20 with schizophrenia, and 20 patients with sexual deviations. Amygdalectomy for patients with normal intellect and posterior hypothalamotomy for those with reduced intellect proved to be the most effective procedure. Symmetrical operations were also effective. In some cases a combination of two target was necessary. In epileptics with aggressivity the combination of amygdalectomy and hippocampectomy yielded the best results. In aggressivity with sexual deviations anterior hypothalamotomy was the most effective operation. Favorable results in aggressivity therapy were recorded in 60% of patients. In patients with criminal sexual deviations, in drug addicts, and in alcoholics, anterior hypothalamotomy was found to be most effective, with favorable results in 50% of patients. In patients with depression, thalamotomy or stimulation of the limbic regions of the thalamus decreased the depression, with favorable results recorded in 66% of patients. The results of the surgically treated patients show that target-oriented stereotactic operations remove psychopathologic symptoms, improve the effectiveness of psychoactive drugs and the social adaptability of patients.
