Key result
Postictal central apnea following a convulsive seizure led to progressive cardiac slowing and arrest, suggesting central respiratory suppression is a probable mechanism of SUDEP.
Case Report (n=1)
This case report provides direct observational evidence that postictal central apnea, leading to secondary cardiac arrest, is a probable mechanism for Sudden Unexpected Death in Epilepsy (SUDEP).
Should not alter SUDEP prevention; leaves open whether central apnea is a dominant mechanism requiring larger studies.
While undergoing video-EEG monitoring, a 20-year-old woman had a 56-second convulsive seizure, after which she developed persistent apnea. The rhythm of the electrocardiogram complexes was unimpaired for approximately 10 seconds, after which it gradually and progressively slowed until it stopped 57 seconds later. Evaluation after successful cardio-respiratory resuscitation showed no evidence of airway obstruction or pulmonary edema. The patient had a previous cardio-respiratory arrest after a complex partial seizure without secondary generalization. Although epileptic seizures are known to be potentially arrhythmogenic to the heart, our observations strongly suggest that one probable mechanism of sudden unexplained death in epilepsy is the marked central suppression of respiratory activity after seizures.

So et al. (2000) conducted a case report in Epilepsy / Near-SUDEP (n=1). Postictal central apnea was evaluated on Cardio-respiratory arrest. Postictal central apnea following a convulsive seizure led to progressive cardiac slowing and arrest, suggesting central respiratory suppression is a probable mechanism of SUDEP.
