Dyskinesia is a type of movement disorder that is subdivided into bradykinesias and hyperkinesias. Bradykinesias are characterized by abnormal slowness (eg, rigidity), difficulty initiating and terminating actions, and the masked facial expression of patients with Parkinson disease. Hyperkinesias are purposeless movements, including akathisia, chorea, dystonia, myoclonus, stereotypy, tic, and tremor.
