5. SUDEP¶
Status: started September 2026. This page and the device guide are student-written from public sources and have not yet been reviewed by a clinician or the Epilepsy Foundation of Minnesota; we are seeking that review. Nothing here is medical advice.
The gap¶
Sudden Unexpected Death in Epilepsy is rare, about one in a thousand adults with epilepsy a year and far lower in children, and it is the outcome every family fears. The Minnesota Department of Health reports around 1,000 deaths a year in the state related to epilepsy or seizures; our own pull of 2018 to 2024 death certificates gives about 870 a year that mention epilepsy or seizures, and about 200 a year that mention epilepsy specifically. How many are SUDEP, nobody knows: it has no diagnostic code, and death certificates record it as "epilepsy" or "undetermined." Illinois, New Jersey, and North Carolina require medical examiners to look for it and report it. Minnesota does not.
The best-supported ways to lower risk are good seizure control, taking medication as prescribed, and supervision at night. Since January 2024 Minnesota Medical Assistance has covered seizure detection devices, wearables that alert a caregiver to a convulsive seizure. Minnesota was the first state to do this. Most eligible families have not heard of it.
What the death data shows¶
We pulled every Minnesota death certificate from 2018 to 2024 that mentions epilepsy or seizures, from the CDC's multiple cause of death files.
| 2018 to 2024, Minnesota residents | Deaths | Per year |
|---|---|---|
| Any mention of epilepsy or seizures on the certificate (G40, G41, R56) | 6,077 | about 870 |
| Any mention of epilepsy (G40, G41) | 1,404 | about 200 |
| Epilepsy as the underlying cause of death | 415 | about 60 |
The two broader counts rose across the seven years, from 728 to 967 for any seizure mention and from 153 to 233 for any epilepsy mention. Deaths with epilepsy as the underlying cause did not trend up, going from 60 in 2018 to 55 in 2024. Rates are low through childhood, rise steadily through adulthood, and climb steeply after 65, when seizures ride along with strokes, dementia, and other conditions. The epilepsy-specific count peaks at ages 65 to 74.
SUDEP is inside the epilepsy count and cannot be separated from it. That is the whole
problem. Only 27 of 87 counties had enough epilepsy-specific deaths in seven years to
report a number at all. Fifty-seven are suppressed as fewer than 10, and three had none
recorded. Those are
the same counties with the smallest districts, the longest ambulance runs, and the farthest
specialists. Source and method:

Where these deaths happen, and how Minnesota compares¶
SUDEP usually happens at home, often during sleep, and often with nobody present. Death certificates almost never say so. The closest public measure is where people died, and for younger Minnesotans that pattern is stark.
| Minnesota, 2018 to 2024 | Died at home | Total |
|---|---|---|
| Epilepsy mentioned anywhere on the certificate, all ages | 458 (33%) | 1,404 |
| Epilepsy mentioned anywhere, ages 1 to 44 | 169 (54%) | 311 |
| Epilepsy as the underlying cause, ages 1 to 44 | 98 (64%) | 152 |
Nearly two in three young Minnesotans whose deaths were caused by epilepsy died at home. That is the population where SUDEP is most likely and least likely to be recorded as such. It is a proxy, not a count: dying at home is not proof of SUDEP, and some SUDEP deaths happen elsewhere.
Minnesota's epilepsy death rate also runs above the national one. Counting every death certificate that mentions epilepsy anywhere, not only those where it was the underlying cause, Minnesota's age-adjusted rate for 2018 to 2024 is 3.0 per 100,000 against 2.4 nationally, about 25 percent higher. Minnesota is clearly above Wisconsin, North Dakota and the United States. Iowa is marginal, since its interval touches ours at 2.9. South Dakota is the only neighbor with a higher estimate, 3.4, and its interval overlaps ours, so we cannot say the two states differ.
One caution before reading too much into that gap. A state's rate depends partly on how often
doctors write epilepsy on a death certificate, which varies. A higher rate may mean more
deaths, better recording, or both. Source and method:

What we are doing this year¶
- A plain-language family guide to the seizure detection device benefit: who qualifies, how to ask, what to do if denied. Distributed through EFMN care coordinators and the pediatric epilepsy clinics.
- A public-records request to find out how many devices Medical Assistance has covered, so the benefit can be measured.
- Keeping the death analysis above current each year as CDC releases data, and adding regional groupings so rural rates can be shown without breaking suppression rules.
- A draft Minnesota SUDEP investigation and reporting law, modeled on Illinois, for the Epilepsy Foundation of Minnesota and the authors of the 2025 epilepsy program law. Its data would feed the mortality count the state is now required to publish.
Try it: could a seizure detection device be covered?¶
Four yes-or-no questions. It explains the Medical Assistance criteria; only the plan and the neurologist can decide.
