[Surgical treatment of drug resistant epilepsy]

Even today, epilepsy is resistant to conservative treatment in a certain number of patients. In many of these cases surgical treatment is a meaningful alternative. The most important procedure is the resection of the epileptogenic focus.

In this article the modern electrophysiological, nuclear medical and neuroradiological diagnostic procedures, together with the various surgical procedures of surgery for epilepsy are presented.
