Associations between long‐term air pollution exposure and plasma amyloid beta in very old adults

Animal studies suggest associations between exposure to air pollutants and increased amyloid beta (Aβ) pathology. However, there is limited research evaluating the relationship of air pollution to Aβ levels in human populations. Therefore, this study examined the role of long‐term air pollution exposure in plasma amyloid levels in a US cohort of older adults.
