Parkinson's Disease 

Introduction

Parkinson's Disease is a neurodegenerative disorder that results in a loss of dopamine (a chemical messenger in the brain), which is important in motor and cognitive functions. Because of the loss of dopamine, Parkinson's is characterized by a generalized slowing of movements in individuals. The biggest risk factor is age, often 60 or older. Some cases are caused by genetics (15%), which is more common in individuals who develop the disease at a younger age. Environmental factors, like significant pesticide and herbicide exposure, along with a history of melanoma or traumatic brain injury, are also linked to Parkinson's. Approximately 90,000 people are diagnosed with Parkinson's every year in the United States.
