A seizure happens when there are certain types of abnormal electrical activity in the brain. During a seizure, you may:
- Lose consciousness
- Stare into space
- Have convulsions (abnormal jerking of the muscles)
- Experience abnormalities of sensation or emotion
If you have two or more seizures that are not due to an illness or other trigger, then it is considered a seizure disorder. This condition is also known as epilepsy. Seizure disorders may be classified by the part of the brain they affect and the kinds of symptoms they cause. One way to categorize into two important groups is:
- Generalized seizure disorder—onset is throughout the brain, not from a single focal location
- Partial seizure disorder (focal seizure)—begins within certain areas of the brain
