Description
Progressive myoclonic epilepsy (EPM) is a syndrome complex characterized by progressive myoclonus, cognitive impairment, ataxia, and other neurologic deficits. PME is a disease that afflicts previously normal children with ever-worsening and soon-intractable myoclonus and epilepsy, usually associated with neurodegeneration, and eventual dementia and early death. PME include Lafora disease, Unverricht-Lundborg disease, the neuronal ceroid lipofuscinoses, type I sialidosis (cherry-red spot myoclonus), Dentatorubro-pallidoluysian atrophy (DRPLA), and type III Gaucher disease. Almost all the autosomal recessively inherited PMEs are lysosomal diseases, with the exception of Lafora disease in which neither the accumulating material nor the gene products are in lysosomes. PME also occurs in various forms of mitochondrial encephalomyopathies, especially in myoclonic epilepsy with ragged-red fibers (MERRF).
