A toxic particle found in polluted urban areas can infiltrate the brain, potentially contributing to degenerative diseases like Alzheimer’s, according to new research.
The study, published in the journal Proceedings of the National Academy of Sciences, adds to growing evidence showing how even low levels of air pollution harm human health. Many previous studies have shown how pollution adversely affects the cardiovascular system, causing lung and heart disease. But scientists are increasingly realizing that the effects could extend to other areas like the brain and pregnancy.
