A University of Montana researcher and her collaborators have published a new study that reveals increased risks for Alzheimer’s and suicide among children and young adults living in polluted megacities.
Dr. Lilian Calderón-Garcidueñas said her group studied 203 autopsies of Mexico City residents ranging in age from 11 months to 40 years. Metropolitan Mexico City is home to 24 million people exposed daily to concentrations of fine particulate matter and ozone above U.S. Environmental Protection Agency standards. The researchers tracked two abnormal proteins that indicate development of Alzheimer’s, and they detected the early stages of the disease in babies less than a year old.
“Alzheimer’s disease hallmarks start in childhood in polluted environments, and we must implement effective preventative measures early,” said Calderón-Garcidueñas, a physician and Ph.D. toxicologist in UM’s Department of Biomedical and Pharmaceutical Sciences. “It is useless to take reactive actions decades later.”
