Focal akinetic seizures as documented by electroencephalography and video recordings.

In three patients with focal epilepsies, focal akinetic seizures that were characterized by ictal paresis of the contralateral arm during preserved consciousness were recorded with EEG and video. MRI and ictal/interictal EEG revealed a frontal or central focus in all patients. Focal akinetic seizures are probably due to epileptic activation of negative motor areas.
