Health experts have highlighted a significant link between air pollution and an increased risk of Parkinson’s disease. Over 10 million people worldwide are affected by this condition, with India accounting for nearly 10% of the global cases.
A recent study published in JAMA Network Open found that higher levels of air pollutants, specifically particulate matter (PM2.5) and nitrogen dioxide (NO2), are associated with a greater risk of developing Parkinson’s disease. Dr. Anshu Rohtagi, a senior neurologist at Sir Ganga Ram Hospital, emphasized that air pollution not only raises the risk of Parkinson’s but can also worsen symptoms for those already diagnosed.
PM2.5 is particularly harmful as it can penetrate the lungs and negatively impact health. It originates from both natural sources, like volcanic eruptions, and human activities such as industrial emissions, vehicle exhaust, and agricultural practices. Besides Parkinson’s, PM2.5 has been linked to other serious health issues, including asthma, heart disease, cancer, diabetes, and Alzheimer’s.
The World Health Organization (WHO) recommends an annual average air quality of 5 micrograms per cubic meter. Unfortunately, 99% of the global population lives in areas where pollution levels exceed this standard.
Dr. Rohtagi pointed out that higher pollution levels, especially in urban areas, increase the likelihood of developing Parkinson’s. For those already living with the disease, exposure to pollutants can lead to faster progression and more severe symptoms.
Pollutants like PM2.5 can even cross the blood-brain barrier, leading to inflammation and oxidative stress, which are believed to play a role in the onset and progression of Parkinson’s disease.
