title: Sudden unexpected deaths in epileptics--a literature review.
abstract: In summary, SUDEP accounts for death in approximately 8% of the young epileptic population. It is commoner in young male epileptics with a long history of generalised seizures, who have a history of head trauma and alcohol excess, and who are taking more than one antiepileptic drug. Most deaths are unwitnessed and occur at home, usually in bed and presumably overnight. Subtherapeutic AED levels do not necessarily imply non compliance, and may simply reflect drug degradation in the plasma after death. Many victims have pulmonary oedema on postmortem examination, and some show ischaemic damage of the heart despite normal coronary arteries. This possibly arises as a result of repeated episodes of vasoconstriction from seizure related catecholamine bursts. Animal studies have demonstrated the occurrence of central apnoea and also support the theory of acute fatal cardiac failure. Possible association with the daily level of geomagnetic activity is reported. The precise reason for a particular seizure being fatal in an otherwise healthy individual is as yet undetermined.
