Post-ictal generalized EEG suppression (PGES) may signal impending sudden unexpected death in epilepsy (SUDEP), according to a recent analysis of 305 seizures that occurred in 17 patients who had definite or probable SUDEP. Researchers found that PGES duration was shorter in patients who died unexpectedly from epilepsy, when compared to living patients. They also found that earlier nursing intervention was linked to shorter seizures after generalized convulsive seizures and may help reduce the risk of SUDEP.
