Generally speaking, epilepsy has very little impact on the life expectancy of patients. Most patients live as long as normal people, and the vast majority of deaths are due to accidents caused by epilepsy, such as drowning, etc. Only a small number of specific types of epilepsy will have an impact on life expectancy. 1. Generalized tonic-clonic seizures: the main onset of this type of epilepsy occurs in childhood. If the brain is functioning normally and treatment is timely, about 85% to 90% of the cases can be relieved. If the patient has brain damage, and the earlier and more frequent the seizures, the worse the prognosis for the patient. 2. Aphasic seizures: Most patients with this type of epilepsy will stop having seizures in adulthood, but patients who have older seizures and are not treated in a timely manner will usually regress to other types of epilepsy. 3. Infantile spasms: The prognosis of this type of epilepsy is very poor, with about 90% of children developing severe intellectual disability and psychiatric disorders, and the mortality rate can be as high as 19%. 4. Lennox-Gastaut syndrome: the prognosis is very poor, some of them will develop drug resistance; some of them can be treated, but the disease is difficult to control; the remaining patients can basically maintain the status quo. If you have epilepsy symptoms, you must be treated promptly, and the earlier the treatment, the less impact it usually has.
