Abstract

In order to asess the accuracy and reliability of ictal EEG, 38 scalp EEG from 10 patients were analyzed by three electroenchephalographers. All patients had been seizure-free for more than one year after temporal lobectomy. Rhythmic discharge in CPS was more common, and its onset was more accurate and reliable than its amplitude asymmetry to determine the lateralization of seizure origin. When all seizures were analyzed, we determined side of seizure onset correctly in 56% to 80% of seizures. When analysis was confined to those seizures in which lateralization was possible, we correctly lateralized all seizures. Postictal slowing was less common and provided little imformation to lateralization judgement.
