The study suggests that air pollution may lead to an increased risk of Alzheimer's disease

people who live in air pollution for a long time may have an increased risk of developing Alzheimer's disease at a young age, an international team of researchers report in the American Journal of Alzheimer's Disease.
Alzheimer's disease is a degenerative disease of the nervous system, with symptoms including memory impairment, adaffles, and personality and behavioral changes. The disease, also known as dementia, has so far been undetred and there are no effective drugs.
Researchers at the U.S. State University of Boise, the University of Leipzig in Germany, and the University of Veracruz in Mexico examined the health of 507 children and adolescents between the ages of 6 and 19.5 with normal cerebrospinal fluid, 354 of whom lived in Mexico City, where air pollution was high, and 153 in cities with better air quality.
results showed that levels of Tau protein, which is associated with Alzheimer's disease and represents axon damage, increased significantly in Mexico City residents and increased with age. Observations by electron microscopes also showed that the average length of neural axons in the frontal cortical cortical layer of adolescent brains in Mexico City was also significantly reduced.
suggests that young people living in areas with high levels of air pollution for a long time will suffer from axons in as little as 20 years, and the risk of developing Alzheimer's disease will increase, the researchers said.
to prevent and control Alzheimer's disease, the researchers suggest that public health authorities should consider strengthening measures to protect the nerves of young people living in areas with high levels of air pollution from damage. (Source: Xinhua News Agency, Li Wei)
