Overview of Parkinson's Disease

Parkinson's Disease

Overview

According to the National Parkinson Foundation, Parkinson’s disease is a slowly progressing brain disorder caused by damaged dopamine-producing neurons in the brain. Dopamine regulates muscle movement. However, when more than 60 percent of those dopamine-producing cells are damaged, the symptoms of Parkinson’s appear. The earliest symptoms, such as sleeping disorders, may appear years in advance of the telling jerky motor movements associated with the disorder.

The National Parkinson Foundation stated that more than 50,000 new cases of Parkinson’s disease are diagnosed each year in the United States. Worldwide, more than four million people have the disease.

The disease most often appears after 50 in men and women. Young-onset Parkinson’s is rare.
