Parkinson's disease (PD) is an incurable brain illness that afflicts more than one million Americans, including many aging Veterans. PD places an unbearable burden on the individual due to progressive impairment of movement and mental function. As a result, patients lose critical abilities such as driving and can become isolated. Although drugs and surgery help movement problems, their benefits are temporary and may cause side effects. Drugs provide limited and temporary benefit for cognition and do not prevent dementia. Animal and preliminary human studies on aerobic exercise show promising results in helping a broad spectrum of symptoms. However, due to limited and inconsistent research results, the long term effects of aerobic exercise on brain health and clinical features in PD is unknown. The investigators will conduct a clinical trial to test the long term effects of aerobic exercise on the brain tissue, movement, mental functions, and driving in PD. If effective, aerobic exercise can be implemented immediately as a low cost, easily accessible treatment in PD.
