Movement Disorders

Abstract

Movement disorders comprise a wide group of neurologic conditions seen by the practicing physician. Abnormal movements are characterized by their phenomenology with much differentiation made by their speed (hypokinetic=‘too slow’ and hyperkinetic=‘too fast’). Such findings may be described as parkinsonism, tremor, dystonia, chorea, athetosis, ballism, myoclonus, tics and/or ataxia. Familiar movement disorder diagnoses include Parkinson disease, Huntington disease and Tourette syndrome. Most movement disorders arise from abnormalities within the basal ganglia and its connections. Symptomatic treatment is available for most conditions, but complete resolution or cure remains elusive.
