Air pollution causes impaired brain function

The results of two recent studies show that air pollution in cities or roads can seriously impair brain function, accelerate the aging process.

The first study was conducted on 680 men aged 51 to 97 years. Accordingly, people living in polluted areas have lower cognitive scores than those who are frequently exposed to low levels of pollution despite differences in social status and opportunities. education.

Dr Melinda Power from Harvard School of Public Health in Boston, Massachusetts, said: 'Cognitive decline in the elderly is a huge public health problem. Our research indicates that air-related air pollution, especially with diesel engine emissions, is a significant cause. It is even more serious than smokers, overweight and obese.

Air pollution related to traffic made
weakened cells in the brain, causing dysfunction.

In addition, 'traffic-related air pollution also causes inflammation and weakening of cells in the brain, causing dysfunction' , she added.

The second study done on animals also showed that small dust particles generated from diesel engines can lead to problems in the process of acquiring and memorizing by reducing the growth of nerve cells. menstruation in the brain.

In this study, researchers at Ohio State University, Columbus, found that exposure to pollutants such as PM2.5 particles (gas particles formed from traffic emissions and steam over 2 , 5 microns) increases inflammatory molecules in the animal's brain.

At the same time, air pollution in general and diesel pollution in particular can freeze arteries and increase the risk of heart attack.
