Seizures are symptoms of a brain problem. They happen because of sudden, abnormal electrical activity in the brain. When people think of seizures, they often think of convulsions in which a person's body shakes rapidly and uncontrollably. Not all seizures cause convulsions.

Generalized seizures are a result of abnormal activity on both sides of the brain. Read more on MedlinePlus.gov.
