Juvenile myoclonic epilepsy (JME), a syndrome belonging to the group of generalized itiopathic epilepsy, is described. Clinical characterization of the syndrome includes three types of epilieptic fits: loss of consciousness, myoclonic fits, and GM attacks – occurring in this order in adolescence, together with a specific EEG pattern. Despite its rather high prevalence rate, JME is seldom recognized. Reasons for this failure are analyzed. Moreover, detailed therapeutic recommendations are given and prognostic perspectives are outlined.
