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 [http://en.wikipedia.org/wiki/Seizure 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]]. For non-epileptic convulsions, see [http://en.wikipedia.org/wiki/Non-epileptic_seizures non-epileptic seizures]. Convulsions may also be referred to as "fits" in some instances.
