Long‐Term Exposure to Air Pollution and Incidence of Parkinson's Disease: A Danish Nationwide Administrative Cohort Study

open access: yesMovement Disorders, EarlyView.
Abstract Background Long‐term exposure to air pollution has been linked to Parkinson's disease (PD) incidence, yet evidence is mixed, partly because of challenges with PD diagnosis and definition. We examined this association in a nationwide administrative cohort.
