In this online CME self-learning program: Parkinson's disease (PD), a central nervous system disease of the autonomic and basal ganglia, neocortex, and spinal cord, is thought to affect about one million people in the United States. Its etiology is thought to include a confluence of factors including age, genetic predisposition, comorbid disease states (e.g., Gaucher’s disease), and environmental factor dynamics. Present in 1% of people over age 65 and 2.5% of those older than 80, its symptoms are the direct result of dopaminergic neuronal degradation along the nigrostriatal tract and include bradykinesia, resting tremor, muscle rigidity, and gait disturbance. This program is supported by an educational grant from Acorda, UCB. Faculty Disclosure: Dr. Lehosit has no relevant financial relationships to disclose.
