EPILEPSIE MYOCLONIQUE JUVENILE PDF

La maladie d’Unverricht-Lundborg (MUL) est une épilepsie myoclonique caractérisée par la survenue, chez le grand enfant ou le jeune adolescent, de crises. 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.

Linkage analysis of juvenile myoclonic epilepsy and microsatellite loci spanning 61 cM of human chromosome 6p in 19 nuclear pedigrees provides no evidence for a susceptibility locus in this region. Diagnosis is typically made based on patient history. There is no progression of severity in these tremors until after the age of Juvenile myoclonic epilepsy JME.
