What is the Age of Onset for Epilepsy?

Question

What is the age at which epilepsy typically occurs?

Answer

The initial onset of epilepsy usually happens before the age of 20, accounting for about 60%-80% of all epilepsy patients. The age before 20 is a high-incidence period for epilepsy, primarily due to primary epilepsy, which often starts to recur before the age of 20. There are two peak age groups, between 6-10 years and 14-17 years. Factors such as parental hereditary factors, abnormal growth and development of certain nerve cells in the patient’s brain, and immune dysfunction are all causes of primary epilepsy.
