Occupational Medicine Grand Rounds - Air Pollution and Dementia

Class description

OEM Grand Rounds: Air Pollution and Dementia

Increasing epidemiologic evidence suggests a link between exposure to air pollution, specifically fine particulate matter (PM_2.5) and nitrogen dioxide (NO₂), and increased dementia risk and worse cognitive outcomes. Hypothesized mechanistic pathways include neuroinflammation, oxidative stress, and vascular damage, which may accelerate neurodegenerative processes. This presentation will highlight recent evidence about air pollution and dementia from epidemiological research, present ongoing research that addresses methodological research, and provide recommendations for advancing research to promote healthy aging.
