Parkinson’s Disease Statistics

 

Due to the nature of the condition, inconsistency of symptoms and possible under-diagnosis (especially in the early stages), Parkinson’s disease statistics vary significantly depending on the source of data. Some source’s suggest up to 40% of people who have the condition go undiagnosed.

 

  • Approximate overall prevalence of Parkinson’s disease in the general population:
    • US  0.3% (1 in 300)
    • UK  0.2% (1 in 500)
  • Between 0.5-1-5 million Americans have Parkinson’s disease and 50,000-60,000 new cases are diagnosed each year. Estimated cost to the US economy $6+ billion.
  • Some 120,000 UK citizens have Parkinson’s disease and 10,000 new cases are diagnosed each year.
  • An estimated 100,000 Canadians have the disease.
  • Worldwide figure is estimated to be 5-6.5 million people.
