How do seizures happen?

ANSWER

A seizure happens because of faulty electrical activity in the brain. You may have one and not know it. But severe seizures can make you lose consciousness and give you convulsions, which is when your body shakes out of control. 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. Fewer than one in 10 people who have a seizure get epilepsy.
