Juvenile Myoclonic Epilepsy (JME) is classified among Idiopathic Generalized Epilepsies, that is, among epilepsies caused exclusively by genetic predisposition. It can affect normal adolescents and young adults, with an age of onset ranging from 10 to 25 years. All patients present myoclonic jerks, which give the name to the syndrome, that is, rapid flexion jerks of the upper limbs.
