Epilepsy is a brain disorder in which a person has repeated seizures (convulsions) over time.
Seizures are episodes of abnormal brain activity that cause changes in attention or behavior. Epilepsy may be due to a medical condition or an injury that affects the brain, or the cause could be idiopathic (of unknown origin).
