How does an epileptic attack differ from a RAS attack?
An EEG (brain wave activity) of an epileptic attack would show excessive elective spike or epileptic discharges, which are not present in a RAS attack. During a RAS attack the EEG goes slow for a few seconds then is flat as the cerebral cortex shuts down, then goes slow again during the drowsy recovery phase before returning to normal. A RAS attack is always precipitated by a shock trigger, which is sometimes difficult to identify.
