"Question Does living within proximity to a golf course affect the risk of Parkinson disease (PD)?

Meaning These findings suggest that pesticides applied to golf courses may play a role in the incidence PD for nearby residents."

"Conclusions and Relevance In this population-based case-control study, the greatest risk of PD was found within 1 to 3 miles of a golf course and risk generally decreased with distance. Associations with the largest effect sizes were in water service areas with a golf course and in vulnerable ground water regions."
