[Experience with the clinical study of the dynamics of severe forms of epilepsy in patients treated by the stereotaxic method].

Clinical course of severe long-lasting (8 to 31 years) forms of epilepsy were observed in 12 patients. Stereotaxic techniques applied, all the patients exhibited improvement in their clinical state. Seizures were abolished in 2 patients, epileptic psychosis in some others. Reduced were the personality changes characteristic of epilepsy. A large-scale clinical introduction of the technique (when indicated) is suggested as well as its earlier use after onset of the disease.
