Sudden unexpected death in epilepsy (SUDEP) has been identified as one of the most prevalent causes of mortality in epilepsy, and SUDEP has consequently become an important topic of research. The causes appear multifactorial, including epilepsy-induced cardiac arrest. Current understanding of autopsy negative sudden unexplained death (SUD) in general population and its relation to sudden arrhythmic death syndrome (SADS) could shed some light in SUDEP. Mutual attention to the findings of sudden death in cardiology and epilepsy are discussed here. We performed a narrative review on SUDEP, epilepsy and molecular/genetic autopsy in this population. A proposal of an extended terminology for SUDEP classification is discussed in light of recent issues related to molecular autopsy and genetics. The extended classification might be a step forward in research protocols and a tool for better understanding SUDEP.
