Living near golf courses may increase the risk of developing Parkinson’s disease, with residents within one mile facing double the risk compared to those farther away, according to a recent study.
Potential Groundwater Contamination
A case-control study published in JAMA Network Open analyzed data from over 400 Parkinson’s patients and 5,000 matched controls in southern Minnesota and western Wisconsin from 1991 to 2015.
The study assessed proximity to golf courses and the use of groundwater sources for drinking water, especially in areas susceptible to contamination from pesticides or herbicides.
The results indicated that individuals living within one mile of a golf course had over twice the likelihood of developing Parkinson’s compared to those living more than six miles away.
Residents whose tap water came from groundwater sources, particularly in regions at risk of pollution, also faced nearly double the Parkinson’s risk if their water source was near a golf course.
Although the study did not identify specific pesticides used on golf courses, previous research has linked these chemicals to Parkinson’s development. Common pesticides include chlorpyrifos, 2,4-dichlorophenoxyacetic acid (2,4-D), and Mancozeb.
Pesticides, known to cause nerve cell damage associated with Parkinson’s, are frequently used on golf courses for turf maintenance despite potential environmental risks.
These chemicals can enter the environment through runoff or groundwater contamination, potentially reaching underground water supplies.
Parkinson’s is a progressive disease without a cure, with the risk increasing with age, typically diagnosed in individuals over 50.
Dr. M. Maral Mouradian, a neurology professor at Rutgers Robert Wood Johnson Medical School Institute for Neurological Therapeutics, emphasized the study’s contribution to understanding the role of environmental exposures in Parkinson’s development.
A separate 2020 study identified a cluster of Parkinson’s cases in a golf community, suggesting that golf courses may use more pesticides per acre than agricultural lands.
Researchers from the 2020 study were contacted by a golf community concerned about the high prevalence of Parkinson’s among its residents. They found that several pesticides used on the golf course, including Mancozeb, 2,4-D, and manganese oxide, have been linked to Parkinson’s risk.
Study Limitations Highlighted
Independent experts caution against definitive conclusions based on the study’s findings.
Dr. Michael Genovese, chief medical adviser at Ascendant New York, noted the absence of direct pesticide exposure measurements, such as blood tests or water chemical analysis.
“While we can’t definitively attribute the Parkinson’s increase to pesticides, the results align with existing research on the brain-damaging effects of these chemicals,” Genovese stated.
Professor David Dexter from Parkinson’s UK raised concerns over the study’s limitations in a statement, highlighting factors like the study’s lack of long-term residency data and differences in urban versus rural living among participants.
Despite these limitations, Genovese emphasized the importance of the study as a potential indicator of pesticide-related health risks. “The findings are compelling and warrant further investigation,” he concluded.
