Parkinson’s disease (also known as Parkinson disease or PD) is a degenerative disorder of the central nervous system that often impairs the sufferer’s motor skills and speech. It is characterized by muscle rigidity, tremor, a slowing of physical movement (bradykinesia) and, in extreme cases, a loss of physical movement (akinesia).
There is currently no cure for Parkinson’s disease. The goals of treatment are to minimize disability, reduce the possible side effects of drug therapy, and help the patient maintain the highest possible quality of life.
