The attacks were documented by closed-circuit televison and electroencephalography, and the patients were selected from around the world for suspected aggressive behavior. None had been accused of murder. Of the 19 patients, 7 showed aggression directed toward inanimate objects or another person. Of these seven patients, only one showed aggressive acts that could have seriously harmed another person. All aggressive acts appeared suddenly and lasted about 29 seconds. All patients could be easily restrained. All automatic acts (i.e., kicking, grabbing, or scratching) were short-lived, fragmentary, and unsustained. The study supports the work of Knox and others who emphasized the extreme rarity of directed aggression during seizures and the near impossibility of commiting murder or manslaughter during random and unsustained attacks. Data tables and 18 references are provided.
