People with mild epilepsy often have no impact on life expectancy; severe cases can die within a few years, or they may die suddenly from seizures that lead to accidents such as car accidents or falling into the water. Their life expectancy is related to seizure status, different physical states, and different control states. 1. Seizure status: In some patients, epilepsy may only take the form of minor seizures, which do not significantly affect daily life and often do not affect normal life expectancy. Some patients may start out with a grand mal form of seizure, or even a persistent state of epilepsy, which may be life-threatening due to convulsions. 2. Physical status: Young people with good physical status and better epilepsy control usually do not affect life expectancy. Elderly people or those with poorer physical condition may have one or two grand mal seizures, which may cause corresponding complications and jeopardize their lives. 3. Controlled status: Some patients may have grand mal seizures, but the overall control is very good, with seizures occurring once or twice a year, and this generally does not affect normal life expectancy. Some patients may have very poor control, with frequent seizures, and may even have accidents that are life-threatening. It is recommended that the life expectancy of patients with epilepsy be judged holistically, and that patients seek further medical attention in a timely manner.
