What is epilepsy?

Epilepsy is a long-term (chronic) disease that causes repeated seizures due to abnormal electrical signals produced by damaged brain cells. A burst of uncontrolled electrical activity within brain cells causes a seizure. Seizures can include changes to your awareness, muscle control (your muscles may twitch or jerk), sensations, emotions and behavior.

Epilepsy is also called a seizure disorder.
