Post-ictal rage and aggression: a video-EEG study.
Post-ictal rage and aggression have been mentioned in the literature but have rarely been documented by video-EEG recording. We studied a patient with dramatic, episodic, seizure-related rage and violence. This mentally retarded man had a lifelong history of seizures. He developed increasing episodic rage and aggression. Caregivers were afraid of him, although there was no record of directed violence. In one of these episodes he fractured his tibia and fibula. Interictal discharges arose from both temporal areas independently. He had focal seizures with secondary generalization. Immediately after cessation of the ictal discharge he became greatly agitated, with undirected aggression, loud screaming, kicking and fighting against the restraints. A video sequence illustrates the behavior. Imaging studies showed bilateral, periventricular, nodular heterotopia in the lateral aspect of both temporal horns and the trigones. Increasingly frequent, severe bursts of rage and aggression were proven to be post-ictal. Documented attacks occurred while he was restrained and this may have been a factor in their severity. Such attacks however, have been described while he was not restrained and these increased in severity and frequency over time. Developmental abnormalities with periventricular, nodular heterotopia in the region of the trigones and inferomesial temporal areas are considered to be causally related to his retardation and epilepsy.
