How do seizures happen?

ANSWER

A seizure happens because of abnormal electrical activity in the brain. It may go nearly unnoticed. Or, in some severe cases, it may cause unconsciousness and convulsions, when your body shakes uncontrollably. Seizures usually come on suddenly. How long and severe they are can vary. A seizure can happen to you just once, or over and over. If they keep coming back, that's epilepsy, or a seizure disorder. Less than one in 10 people who have a seizure get epilepsy.
