A recent article published in nature.com released findings that the prevalence of Parkinson's Disease in North America, may be as much as 50-100% higher than previously estimated. While previous estimates have varied for unknown reasons, improving the accuracy of population measurements is critical as this demographic information is used for clinical, research, and policy making decisions that affect treatment and support of persons with PD.

Using the Ontario Health care and Medicare program datasets, produced incidence rates that were 1.5–2.0 times higher than found in among Kaiser Permanente Northern California members or the HAAS and Rochester Epidemiology estimates. The current study estimates of age-sex-adjusted incidence of PD ranged from 108 to 212 per 100,000 among persons ages 65 and older, and from 47 to 77 per 100,00 among persons ages 45 and older.​
