Long-term exposure to air pollution is linked to faster cognitive decline among older adults


  • People living in urbanized areas with higher levels of ambient air pollution are more likely to experience faster cognitive decline.

Why this matters

    These findings obtained using multidimensional data in over 6,000 residents of northern Manhattan add to the growing scientific evidence on the adverse effect of air pollution on cognitive aging and brain health. The identification of novel, modifiable risk factors for cognitive decline could help to reduce its impact on elderly individuals.
