Epilepsy is a medical condition that affects the brain and causes seizures. A seizure happens when the brain's electrical signals suddenly fire in an unusual pattern, like a brief electrical storm inside your head. During a seizure, a person might lose consciousness, have uncontrollable muscle movements, or experience strange sensations, depending on which part of the brain is affected.

People with epilepsy have recurring seizures, which means the seizures happen more than once over time. Some people have seizures that are barely noticeable, while others have more dramatic ones. Doctors can often control epilepsy with medication that helps regulate the brain's electrical activity, allowing many people with the condition to live full, active lives.

Epilepsy affects people of all ages. Many famous and successful people have had epilepsy, including inventors, athletes, and artists. With proper treatment and understanding, people with epilepsy can live full, active lives.
