Whats epilepsy?

Epilepsy comes from a Greek word meaning "to hold or seize," and people who have epilepsy have seizures. You might also hear a seizure called a convulsion, fit, or spell.
Seizures happen when there is unusual electrical activity in the brain. Your brain cells are constantly sending out electrical signals that travel along nerves to the rest of the body. These signals tell the muscles to move. During a seizure, a person's muscles tighten and relax rapidly or stop moving completely. Seizures come on suddenly, and people who have them cannot control their muscles while they are having a seizure. If too many brain cells are sending signals at the same time, it causes an overload and a person may pass out and shake all over. People who have epilepsy may have seizures only once in a while or as frequently as every day.
