© 2025Objective: The major source for sudden unexpected death in epilepsy (SUDEP) case series has been medical case record review, however most deaths occur at home, with no clinical witness. We set out to describe SUDEP characteristics using reports of deaths from third-parties and explore the effectiveness of this reporting as a sampling technique. Methods: We collected characteristics of the deceased and narratives surrounding death via the SUDEP Action UK Epilepsy Deaths Register (EDR). We included adults and older adolescents with a certified cause of death, and narrative in keeping with definite or probable SUDEP. We collected demographics, details of follow-up, events leading to death, and attitudes towards condition and treatment in life from third-party reporters between 2013 and 2024. Results: 407 SUDEP cases were identified, 268 definite, 16 definite plus, 112 probable and 11 near SUDEP. Ages ranged from 15–85 years, with the majority (76 % of cases) occurring between the ages of 19 – 49 years; 59 % were male. Most cases were found in the prone position (63 %), and death most frequently occurred during sleep (69 %). Inconsistencies were identified between death certification and reporter accounts in 24.8 % of cases, where SUDEP was consistent with the reporter account but not reflected in official death records. Increased frequency of SUDEP was observed with lengthening duration of epilepsy, with 41 % diagnosed more than 10 years prior to death. 24 % were reported as sometimes forgetting to take their medications. 16 % of cases lived alone and 16 % of deaths were witnessed. Significance: Third-party death reports are an effective, under-utilised tool to sample SUDEP deaths which may currently be missed by conventional mortality records. SUDEP in the EDR was seen more frequently in young adults, those with longstanding epilepsy and during sleep and were most often found in a prone position. Heterogeneity across the spectrum of SUDEP deaths should prompt clinicians to warn all those with epilepsy of their SUDEP risk.
