 Juvenile myoclonic epilepsy

Juvenile myoclonic epilepsy (JME), also known as Janz syndrome, is a fairly common form of generalized epilepsy of presumed genetic origin (previously known an idiopathic generalized epilepsy), representing 5-10% of all epilepsy cases.This disorder typically first manifests itself between the ages of 12 and 18 with sudden brief involuntary single or multiple episodes of muscle(s) contractions caused by an abnormal excessive or synchronous neuronal activity in the brain.
