Key Points

To resolve ambiguities in existing diagnostic criteria by proposing a unified definition and classification system for sudden unexpected death in epilepsy (SUDEP).
Synthesized and refined two decades of complementary SUDEP definitions into a unified framework.
Established nine core recommendations addressing terminology, timing, exclusionary criteria, and preexisting conditions.
Standardized the term to 'unexpected' rather than 'unexplained' and introduced 'SUDEP Plus' for deaths with non-fatal preexisting contributing conditions.
Defined specific diagnostic thresholds, requiring death within 1 hour of an acute terminal event, status epilepticus duration of ≥30 minutes as an exclusion, and resuscitation survival of >1 hour for 'Near-SUDEP'.
Clarified ambiguous scenarios by eliminating a standalone asphyxia category and classifying water deaths without evidence of submersion as 'Possible SUDEP'.
