Disease characteristics

Excerpted from the GeneReview: Parkinson Disease Overview
Parkinsonism refers to all clinical states characterized by tremor, muscle rigidity, slowed movement (bradykinesia) and often postural instability. Parkinson disease is the primary and most common form of parkinsonism. Psychiatric manifestations, which include depression and visual hallucinations, are common but not uniformly present. Dementia eventually occurs in at least 20% of cases. The most common sporadic form of Parkinson disease manifests around age 60; however, young-onset and even juvenile presentations are seen.
