Clean air is important for a healthy brain

Cars and factories produce a fine particulate matter called PM2.

In a research letter published today in the journal Alzheimer’s Disease and Dementia: In the Journal of the Alzheimer’s Association, researchers from the University of Southern California describe how their laboratories are separate Independently reported recent signs of decreased neurotoxicity (damage to the brain or nervous system caused by exposure to toxic substances) of PM2.

Professor Caleb Finch and Associate Professor of Gerontology and Sociology Jennifer Ailshire of the USC Leonard Davis School of Gerontology (USC Leonard Davis School of Gerontology) Concerned about PM2.

According to a study published in the Journal of Alzheimer's Disease earlier this year by Alzheimer’s Disease, there was a strong correlation between cognitive deficits and air pollution in people with lower education levels in 2004.

According to data from the National Health and Retirement Study (Health and Retirement Study), her research shows that adults 65 years of age and older with less than 8 years of education are at greater risk of cognitive impairment when exposed to PM2.

El Hill said that one possible factor is the reduction of PM2.

It is worth noting that in 2014, few study participants lived in places where the annual average concentration of PM2.

“Improving air quality across the country is a great success in public health and environmental policies

Finch's research on mice published in the Journal of Alzheimer's Disease earlier this year also found that air pollution is less neurotoxic over time

Since 2009, Finch and his research team have been studying pollution levels in the same location in Los Angeles and its effects on the brains of mice

During the years that Vinci and Elshall conducted research, the composition of air pollution in the United States has also changed

According to the US Environmental Protection Agency, from 2000 to 2020, the national PM2.

Finch and Alhill emphasized that their findings cannot assess the potential benefits of improving air pollution on cognitive decline and the risk of dementia

Finch said: "Our findings emphasize the importance of efforts to improve air quality, as well as the continuing importance of demographics and air pollution neurotoxicity experimental evaluation

Finch and Jiuqian "JC" Chen are associate professors of preventive medicine at the Keck School of Medicine at the University of Southern California.
