Parkinson's Disease Overview and Estimated Market Size
- Parkinson's disease is a chronic, degenerative neurological disorder that affects one in 100 people over age 60 (average age of onset)
- People have been diagnosed as young as 18
- There is no objective test, or biomarker, for Parkinson's disease, so the rate of misdiagnosis can be relatively high, especially when the diagnosis is made by a non-specialist
- Estimates of the number of people living with the disease therefore vary, but recent research indicates that at least one million people in the United States, and more than five million worldwide, have Parkinson's disease
