Parkinson disease (PD) is the second most common neurodegenerative disorder found in the elderly, currently affecting an estimated 2% of individuals 60 years or older. PD is a multifactorial disease in which both environmental and genetic factors are significantly associated with disease onset. Although symptoms of the disease may present with a tremor or perhaps a speech problem, by the time the symptoms are evident, it is often too late to stop the progression of the disease.
