Possibly: Most people with epilepsy live a full and healthy life, and should not spend time worrying about potential epilepsy-related catastrophes. While epilepsy can increase a person's risk of dying about 1.6 to 3 times , it also depends on the type of epilepsy. Sudep or sudden unexpected death in epilepsy can occur in 15-20% of epilepsy patients but sz are usually severe and uncontrolled.
