ABSTRACT
Sudden deaths in infants and children represent a profound and tragic event that continues to challenge researchers despite extensive investigation over several decades. The predominant phenotype, sudden infant death syndrome (SIDS), has evolved into the broader category of sudden unexpected infant death (SUID). In older children, a less understood phenomenon known as sudden unexplained death in childhood (SUDC) has garnered attention. Additionally, sudden unexpected death in epilepsy (SUDEP) constitutes a rare but recognized complication of epilepsy. Recent investigations indicate overlapping clinical, neuropathological, and genetic characteristics among SUID, SUDC, and SUDEP. Common features include death occurring during sleep, discovery in the prone position, hippocampal abnormalities, and genetic variations associated with epilepsy or cardiac arrhythmias. Notably, video recordings in certain examples of SUDC have captured ‘convulsive’ episodes preceding death in children without prior seizure history, suggesting that seizures may contribute more significantly to sudden paediatric deaths than previously presumed. This review explores these shared elements, underscoring their importance in formulating possible preventative measures against these devastating conditions.
