Epilepsy & Seizures
Progressive myoclonus epilepsies
The progressive myoclonus epilepsies are a group of genetic and rare disorders clinically characterized by the presence of typically refractory myoclonic seizures, tonic-clonic seizures, and progressive neurologic deterioration. The 5 major progressive myoclonus epilepsy entities are Unverricht-Lundborg disease, myoclonic epilepsy with ragged red fibers (MERRF), Lafora disease, the neuronal ceroid lipofuscinoses, and sialidoses. Prognosis is disease-specific and, thus, highly variable.
