Epileptic seizure

Abstract

Jonathan Ivan

A seizure, formally mentioned as a convulsion, could also be a period of symptoms because of abnormally excessive or synchronous neuronal activity within the brain. Outward effects vary from uncontrolled shaking movements involving much of the body with loss of consciousness (tonic-clonic seizure), to shaking movements involving only a neighborhood of the body with variable levels of consciousness (focal seizure), to a subtle momentary loss of awareness (absence seizure). Most of the time these episodes last but 2 minutes and it takes a short time to return to normal. Loss of bladder control may occur
