Air pollution exposure increases risk for Parkinson’s disease

Air pollution exposure increases risk for Parkinson’s disease

Air pollution is a significant environmental issue that poses numerous health risks, including an increased risk for Parkinson’s disease (PD), according to a recent study published in JAMA Network Open. The study, conducted by Brittany Krzyzanowski, Ph.D., from the Barrow Neurological Institute in Phoenix, and colleagues, aimed to investigate the association between air pollution exposure and PD risk.

The researchers analyzed data from 346 patients with PD and 4,813 matched controls from the Rochester Epidemiology Project spanning from 1998 to 2015. They found that higher exposure to particulate matter with a diameter of <2.5 ÎĽm (PM2.5) was linked to an increased risk of PD, with the greatest risk observed in populations within metropolitan cores. Specifically, individuals in the top quintile of PM2.5 exposure had a 23% higher risk of developing PD compared to those in the bottom quintile. Furthermore, increased exposure to nitrogen dioxide (NO2) was also associated with a higher risk of PD, with individuals in the top quintile having a 13% increased risk compared to those in the bottom quintile. The study also revealed that exposure to air pollution was linked to specific clinical characteristics of PD, such as akinetic rigid presentation. Interestingly, among individuals with PD, higher PM2.5 exposure was associated with a greater risk of developing dyskinesia, a common motor complication of PD. This finding highlights the detrimental effects of air pollution on disease progression and symptom development in PD patients. The study authors noted that the U.S. Environmental Protection Agency recently revised the annual PM2.5 standard from 12 ÎĽg/m3 to 9 ÎĽg/m3 due to mounting evidence of negative health effects. Based on their findings, the authors suggested that the upper limit should be further lowered to 8 ÎĽg/m3 to protect public health.

Overall, this study underscores the importance of addressing air pollution as a public health concern and implementing stricter regulations to reduce exposure levels. By understanding the link between air pollution and PD, we can take proactive measures to mitigate the risks and improve the quality of life for individuals at risk of developing this neurodegenerative disorder.
