Summary

Story summary

The study published in Science indicates exposure to particulate matter with a diameter of 2.5 micrometers (PM2.5) may raise Lewy body dementia risk.
Researchers note PM2.5 exposure promotes clusters linked to Lewy body dementia.
In mice, PM2.5 exposure caused damage, a finding not observed in alpha-synuclein knockout mice.
The findings imply air quality regulation may protect cognitive health.
Further work is needed to identify harmful PM2.5 components and genetic interactions.
