UNCERTAINTY: How can the risk of SUDEP (Sudden Unexpected Death in Epilepsy) be reduced in people with epilepsy?  (JLA PSP Priority 4)
Overall ranking 4
JLA question ID 0110/4
Explanatory note SUDEP stands for Sudden Unexpected Death in Epilepsy. It occurs when an otherwise healthy person with epilepsy dies suddenly and unexpectedly, and no clear cause of death can be found. It is most likely that more than one cause of SUDEP will be identified. Since most deaths occur after a generalized tonic-clonic seizure, it is likely that the seizure itself is a contributing factor. Possible theories being investigated include changes in breathing patterns, heart rate, or brain function. There may also be a genetic link between seizures and abnormal heart function, meaning that people with epilepsy may be more prone to irregular heart rhythms. However, it is unlikely that all SUDEP-related deaths occur in the same way, and more research is needed to better understand the causes of SUDEP and how the risk can be reduced.
