Prolonged post-ictal confusion as a manifestation of continuous complex partial status epilepticus: A depth EEG study

Abstract

We report a peculiar depth-EEG recording of prolonged post-ictal confusion which proved to be continuous complex partial status epilepticus. A 33 year old male with intractable medial temporal lobe epilepsy exhibited this ictal EEG recording. After repetitive habitual complex partial seizures, and an ensuing short lucid interval with intact memory and full communicability, the patient became more and more unresponsive and, finally, even cataleptic. Concurrent with this change in responsiveness, an EEG revealed a gradual and steady increase of ictal EEG activity. Immediately after intravenous diazepam infusion, this ictal EEG activity was suppressed and the patient began to move. This case confirms that a paradoxical excitation can occur after clustered complex partial seizures, instead of the well-known neuronal exhaustion. (C) 2000 BEA Trading Ltd.
