Researchers find link between air pollution and Alzheimer’s disease

Exposure to diesel soot and other sorts of fine-particle pollutants in the air may significantly increase the risk of dementia and Alzheimer’s disease, according to a new study.

Led by Dr. Jiu-Chiuan Chen of USC, a team of researchers found that elderly women living in parts of the U.S. where fine-particle air pollution surpassed federal health standards were roughly twice as likely to suffer dementia and the Alzheimer’s disease.

Women with high genetic predisposition for the Alzheimer’s disease faced an even higher risk, a 263 per cent higher risk for the devastating disease, than others.

The researchers also warned against the Trump administration’s potential actions against existing environmental regulations, which may soon come under heavy fire.

Speaking on the topic, Chen warned, “If people in the current administration are trying to reduce the cost of treating diseases, including dementia, then they should know that relaxing the Clean Air Act regulations will do the opposite.”

If findings of the new study hold up in the general population, air pollution could be responsible for nearly 21 per cent of overall dementia cases.

The researchers reported their findings in the latest (Jan. 31st) edition of the journal Translational Psychiatry.
