The life expectancy of a patient suffering from epilepsy cannot be determined. If the epilepsy is chronic, the number of seizures is very small, and the symptoms of the seizures are mild, the patient can usually survive for 30-50 years. If the epilepsy is more severe, with frequent seizures and obvious symptoms such as foaming at the mouth, convulsions of the limbs and loss of consciousness during the seizures, it may affect the patient’s life. Because of the possibility of limb or cerebrovascular accidents during the seizure, if there is no one around during the seizure, the sudden fainting may lead to traumatic brain injury, cerebral hemorrhage, etc., and the lack of timely treatment or the amount of hemorrhage may quickly lead to clinical death. Patients with epilepsy who are actively treated and have stable disease control or are cured after epilepsy surgery, there is not much difference between the life expectancy of epilepsy patients in this category and that of normal people.
