BAFME must be differentiated from epilepsy syndromes with prominent myoclonus features. Patients may easily be misdiagnosed as having juvenile myoclonic. Juvenile myoclonic epilepsy (JME), also known as Janz syndrome, is a fairly common form of generalized epilepsy of presumed genetic origin representing.
