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.

Hum Mol Genet ; 6: Benign adult familial myoclonic epilepsy BAFME is an inherited epileptic syndrome characterized by cortical hand tremors, myoclonic jerks and occasional generalized or focal seizures with a non-progressive or very slowly progressive disease course, and no signs of early dementia or cerebellar ataxia.

There is no progression of severity in these tremors until after the age of Diagnosis is based on clinical and electrophysiological findings. Janz D, Durner M.

Valproate, levetiracetam, and benzodiazepines are most beneficial in the treatment of cortical tremors and myoclonus due to their combined antiepileptic and antimyoclonic effects. These are brief episodes of involuntary muscle contractions occurring early in the morning or shortly before falling asleep.

There is also a higher rate of females showing JME symptoms eppilepsie males. These events typically occur either early in the morning or upon sleep deprivation.

BAFME has been mapped to at epilesie 4 different chromosomal loci.

Electroencephalographic EEG findings include a photomyoclonic response along with abnormality of polyspikes and waves. The characteristic signs of JME are brief episodes of involuntary muscle twitching.
