WHAT IS NEEDED FROM A NEUROPSYCHOLOGICAL POINT-OF-VIEW

This article discusses the neuropsychological aspects of surgery for epilepsy, and what is needed in EEG evaluation to permit the best use of neuropsychological data to help identify the most promising surgical candidates. Neuropsychological changes after surgery are first discussed, and it is noted that changes in memory are most important with less important fluctuations in intelligence and language and with other areas showing few or no changes. Emotional and psychosocial outcomes of surgery are dependent upon relief from seizures, with substantial relief being essential for improvement to be observed. Finally, it is noted that a combination of EEG and neuropsychological variables results in the best prediction of seizure relief, but reliable EEG data are critical to this effort. Obtaining such data frequently necessitates EEG monitoring, frequently with invasive electrodes. Such information often provides the dearest information and the best chance of assisting patients with epilepsy.
