[Two cases of ictal automatisms of frontal lobe origin].
Two cases of ictal automatisms of frontal lobe origin are reported. Both two cases had automatisms characterized by abrupt onset and ending, short duration, preservation of consciousness and frequent attacks in cluster. The ictal manifestations included rocking of body and violent thrashing of limbs in prone position with loud screaming. No initial staring or postictal confusion was noted. Interictal EEGs showed spikes in the frontal area. Ictal EEGs began with attenuation of background activity and/or fast rhythmic waves dominant in the frontal area. Just after clinical seizures, high voltage slow waves in bilateral frontal areas and rhythmic alpha waves in the occipital areas were recorded. The EEG findings suggested that the paroxysmal activities were localized in bilateral frontal lobes, not spreading to the temporal lobe.
