As AQI deteriorates in Delhi and Mumbai, study says air pollution leads to 56% higher risk of Parkinson's disease
PTI. According to lead researcher Brittany Krzyzanowski from the institute, previous studies have shown fine particulate matter, or PM2.5 can cause inflammation in the brain, which is "a known mechanism by which Parkinson's disease could develop". Published in the journal Neurology, the US researchers have found that the relationship between air pollution and Parkinson's disease was not the same in every part of the United States, as it varies in strength by region.
Meanwhile, according to SAFAR-India data at 6 a.m., the national capital's (New Delhi) air quality remained 'very poor' for the fourth straight day, with the pollution levels entering the 'severe' zone in parts of the city.

While most of the places in the National capital, the AQI was reported as very poor or severe. Bawana reported an AQI of 389, Anand Vihar (418), IGI Airport (330), Punjabi Bagh (380), and ITO (328).
The US researchers, in their study, identified nearly 90,000 people with neurological disease from the US's Medicare dataset of about 22 million people. After the findings, they even calculated the average annual concentrations of fine particulate matter in these specific regions and were able to identify an association between a person's previous exposure to fine particulate matter and their later risk of developing Parkinson's disease, said the report.
