Progressive myoclonus epilepsy (PME) is a group of conditions involving the central nervous system and representing more than a dozen different diseases. These diseases share certain features, including a worsening of symptoms over time and the presence of both muscle contractions (myoclonus) and seizures (epilepsy). Patients may have more than one type of seizure, such as petit mal or grand mal. PME is progressive, but the rate of progression may be quick or slow, depending on the underlying disease.
Progressive myoclonus epilepsy (PME) is different from myoclonic epilepsy. In myoclonic epilepsy, the myoclonic jerking motions occur as part of the seizure. In PME, myoclonus occurs separately from seizures, the two respond differently to the same drugs, they evolve differently during the natural history of the disease, and they cause different problems for the patient. Some drugs that are good for seizures, e.g. phenytoin and carbamazepine, may tend to make the myoclonus worse.
