[Treatment of dyskinetic syndromes]

Dyskinetic syndromes are conditions with involuntary movements. They can have different causes, but are often due to dysfunction of the basal ganglias. The clinical picture varies but all show spontaneous alterations in intensity as well as deterioration with stress. This often leads to misjudgment of cases of dyskinesia. It is however important to be aware of these syndromes as medical treatment is effective in many cases. The treatment of tremor, tics, chorea, myoclonus, dystonia and medically induced dyskinesia is reviewed and the clinical pictures are briefly described.
