Epilepsy is a central nervous system disorder (neurological disorder) in which the nerve cell activity in your brain is disturbed, causing a seizure during which you experience abnormal behavior, symptoms and sensations, including loss of consciousness.

Seizure symptoms vary. Some people with epilepsy simply stare blankly for a few seconds during a seizure, while others repeatedly twitch their arms or legs.

About 1 in 100 people in the United States may have an unprovoked seizure once in life. However, a solitary seizure doesn't mean you have epilepsy. At least two unprovoked seizures are generally required for an epilepsy diagnosis.

Even mild seizures may require treatment because they can be dangerous during activities such as driving or swimming. Treatment, which generally includes medications or sometimes surgery, may eliminate or reduce the frequency and intensity of seizures. Some children with epilepsy even outgrow the condition with age.
