Examine research exploring long-term fine particulate air pollution's selective effects on semantic memory and implications for cognitive aging and health equity.
Key Takeaways
- Seventeen years of higher long-term PM2.5 exposure was linked to degraded semantic memory performance
- Observed semantic decline exceeded what would be expected from ten years of aging
- Targeted reductions in long-term PM2.5 exposure could lower dementia risk and health inequities
