Preoperative neurophysiological study of patients with epilepsy caused by damage to the temporal lobe

The paper deals with the development and substantiation of various neurophysiological procedures during preoperative examination of patients with symptomatic epilepsy. The neurophysiological findings of 133 patients with drug-resistant temporal lobe epilepsy were applied. Unprogressive damage to the medial portions of the temporal lobe was verified in 18 patients. Low- and higher-grade malignancy of the temporal lobe was confirmed in 91 and 24 patients, respectively. This yielded an algorithm of the optimum neurophysiological preoperative examination. Emphasis is laid on the differences in applied procedures depending on the side of organic lesion location. Thus, the use of the developed algorithm makes it possible to lighten the selection of candidates for surgical treatment of drug-resistant symptomatic epilepsy and to optimize the examination of epileptic patients with different types of brain damage.
