Electrical activity in the brain seizure.

A seizure usually affects how a person appears or acts for a short time. These changes can cause dramatic noticeable symptoms or in other cases no symptoms at all. Doctors generally classify seizures as either focal or generalized based on how and where abnormal brain activity begins.
