Seizure-related injuries and sudden unexpected death in epilepsy (SUDEP) are severe complications of epilepsy. Risk factors include pharmacoresistant epilepsy, high frequency of tonic-clonic seizures, and absence of nocturnal supervision. Seizure detection devices are medical devices that rely on movement and other biological parameters to detect seizures, and are increasingly used to alert care givers. There is no high-grade evidence that seizure detection devices prevent SUDEP or seizure-related injuries, but international guidelines for their prescription were recently published. A degree project at Gothenburg University recently performed a survey among epilepsy teams for children and adults at all six tertiary epilepsy centres and all regional technical aid centres. The surveys showed marked regional variation in the prescription and dispensation of seizure detection devices. National guidelines and a national register would promote equal access and facilitate follow-up.
