Neurologic disorders that result in a paucity or slowness of movement are termed hypokinetic disorders. The category of hypokinetic disorders is represented by Parkinson disease and other causes of parkinsonism. Hyperkinetic disorders are characterized by excessive, involuntary movements. Hyperkinetic disorders can usually be placed into one of five main categories of abnormal movement: dystonia, chorea, tremor, myoclonus, or tic.
