(July 2015) Myoclonus is a brief, involuntary twitching of a muscle or a group of muscles. It describes a medical sign and, generally, is not a diagnosis of a disease. These myoclonic twitches, jerks, or seizures are usually caused by sudden muscle contractions (positive myoclonus) or brief lapses of contraction (negative myoclonus).
Myoclonus is the medical term for the sudden contraction of a muscle or group of muscles. This is a neuromuscular problem. It can happen anywhere, but is quite common in the legs. Myoclonus may be an indication of an underlying seizure disorder like epilepsy. It is characteristic of some hereditary disorders, such as lipid storage diseases. It is also commonly seen in metabolic diseases that cause an increase in urea in the bloodstream. Some drugs have side effects that cause abnormal muscle movements, including myoclonus. Alcohol and drug withdrawal also may be a cause.
