Seizure

Say: SEE-zhur

You might hear a seizure called a convulsion, fit, or spell. Most people think of a seizure as shaking all over and losing control of your body, but there are different kinds of seizures.

All types of seizures are caused by abnormal electrical activity in the brain. The brain uses electrical signals, and if these go a little haywire, a person can have a seizure. Some people may have only one seizure in their whole life. Others might have seizures as part of a condition called epilepsy. People with epilepsy usually need medicine to control their seizures.
