Parkinson’s Disease in Older Adults

Parkinson’s disease (PD) is a progressive degenerative disorder of the central nervous system that mainly affects an individual's movement. Early in the course of the disease, the most obvious symptoms include shaking, rigidity, slowness of movement, difficulty walking, and gait imbalance. The incidence and prevalence of PD increase with age; 3% of dually eligible beneficiaries have Parkinson’s disease.[1]
