What is juvenile myoclonic epilepsy?

A form of epilepsy..: Usually seen in adolescents - described as involuntary spasms (or jerking) of an upper extremity (such as flinging a comb or a toothbrush) which may, about 1/4 of the time, also demonstrate generalized seizures later in life. Most do not, however. Usually worse in kids that are overly fatigued (e.g. Staying up late/poor sleep) and can sometimes be attributed to "typical teen behavior".

JME: Juvenile Myoclonic Epilepsy is a tendency to have seizures. It presents in teenagers and young adults. It includes myoclonic (muscle twitching) seizures and convulsive seizures.
