Neuropsychological evaluation before and after surgical treatment of temporal lobe epilepsy

We present the results of pre- and postoperative neuropsychological evaluations of 58 patients with temporal lobe epilepsy who underwent a chronic intracranial EEG monitoring and a subsequent standard anterior temporal lobectomy. Wada's test provided valuable information on the speech dominant side and on the focus localization. Some warning signs as well as verbal automatisms indicated the effect for focus localization and lateralization. The results of interictal neuropsychological tests suggested that each subgroup of TLE performed differently. A postoperative neuropsychological performance has improved in many tests that may be explained by the diminished epileptic bombardment resulting from the resection.
