Myoclonus is a rapid involuntary twitching of muscles. Myocloni are a side effect of many neurological conditions, but they can also happen in healthy people. As an example, twitching muscles when falling asleep are normal. Mycloni are a common symptom of epilepsy. Other less common diseses that provoke myocloni include encephalitis, Tics, and certain types of porphyria.
Certain analgesics can provoke myocloni.
