Differential diagnosis in pseudoepileptic seizures.

With increasing use of intensive video-EEG monitoring, publications concerning pseudoepileptic seizures have burgeoned, but without clarification concerning differing psychopathologic mechanisms and without distinction of different syndromic varieties. The frequent concurrence of pseudoepileptic and epileptic seizures has not been sufficiently recognized, and an undue reliance on clinical experience on the one hand and individual tests such as EEG on the other has proven equally misleading in this group of cases.
