Definition

Parkinsonism is characterized by four cardinal features. They include tremor, bradykinesia, rigidity, and gait problems. Symptom onset is classically unilateral. The tremor is most pronounced at rest. Parkinson’s disease is the most common cause of Parkinsonism. The diagnosis of probable Parkinson’s disease is made by the demonstration of most of the cardinal features of Parkinsonism, an asymmetrical onset, and a symptomatic response to levodopa or a dopamine agonist. Exclusion criteria for Parkinson’s disease include exposure to medications known to cause Parkinsonism (neuroleptics and antiemetics), cerebellar deficits, a history of significant strokes, corticospinal tract signs, and oculomotor deficits other than slight limitation of upward gaze.
