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. 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 |
Both counts rose across the seven years, from 728 to 967 for any seizure mention and from 153 to 233 for epilepsy. 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; the other 60 are suppressed as fewer than 10, and those are
the same counties with the smallest districts, the longest ambulance runs, and the farthest
specialists. 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.
Myth or fact¶
1. SUDEP is common.
Myth. About 1 in 1,000 adults with epilepsy per year, and about 1 in 4,500 children. It is rare, and rarer still when seizures are controlled.
2. A seizure alert watch prevents SUDEP.
Myth. No device has been proven to prevent it. Devices detect convulsive seizures and bring a caregiver faster, which supports nighttime supervision, a recognized risk reducer.
3. Minnesota counts SUDEP deaths.
Myth, for now. SUDEP has no diagnostic code and Minnesota has no reporting rule, so the number is unknown. Illinois, New Jersey, and North Carolina require examiners to report it.
4. Taking medication as prescribed lowers the risk.
Fact. Uncontrolled generalized tonic-clonic seizures are the main risk factor; adherence and good seizure control are the most consistent protective steps.

Note
Ask your neurologist about your own or your child's risk. Most people with epilepsy have a low risk, and it is lower still when seizures are controlled.
