An estimated 1 million U.S. adults have Parkinson's disease (PD), a progressive neurodegenerative movement disorder that affects motor and cognitive function and significantly impairs quality of life. Neurologists, gerontologists, primary care physicians, and other clinicians comprise a multidisciplinary team collaborating to improve outcomes for patients with PD. Underlying competency and knowledge gaps in the management of PD continue to exist among clinicians who treat patients with PD. The root causes underlying knowledge and clinical practice gaps include clinician time constraints and the need for broader dissemination of emerging data on the management of PD.
