A convulsion is a medical condition where body muscles contract and relax rapidly and repeatedly resulting in an uncontrolled shaking of the body. Because a convulsion is often a symptom of an epileptic seizure the term convulsion is sometimes used as a synonym for seizure. However not all epileptic seizures lead to convulsions and not all convulsions are caused by epileptic seizures. Convulsions are also consistent with an electric shock.
