Despite awareness and treatment measures, people with epilepsy are at a higher risk of death than people who don’t have epilepsy. Numerous studies have discussed the mortality rate along with all the possible risks factors involved.
One 2016 study published in Epilepsia highlighted frequent (uncontrolled) generalized tonic clonic seizures as a clear risk factor for sudden unexpected death and also discussed the nocturnal (nighttime) seizures as an additional risk factor. Taking antiseizure medications can reduce the frequency of seizures and helps minimize this risk.
According to Brain: A Journal of Neurology, the risk of sudden death may also be slightly higher shortly after you first start experiencing seizures. This is likely due to the fact that you might be undiagnosed or recently diagnosed, and your medications haven’t taken hold yet.
