Complex partial seizures on closed-circuit television and EEG: a study of 691 attacks in 79 patients.

Automatisms of 691 complex partial seizures in 79 patients were studied on closed-circuit television (CCTV) and by electroencephalography. Simple stereotyped perseverative automatisms such as chewing, swallowing, and fumbling with clothes or sheets followed an initial motionless stare and lapse of consciousness in type I attacks. Ambulatory automatisms, bilateral arm and leg perseverative movements, and tonic adversive head or eye movements (or both) characterized type II attacks, in which a motionless stare was not observed. Type III started with a drop attack followed by confusion, amnesia, and gradual recomposure. Some type II and III attacks are suspected to begin in areas outside the temporal lobe, while type I attacks are thought to originate from the temporal lobe. Further studies using CCTV and depth electrode recordings are necessary to verify these suspicions.
