Fine-particle pollution is now directly tied to Lewy body dementia
A new peer-reviewed study in Science connects long-term exposure to fine particulate matter (PM2.5) with higher risk of Lewy body dementia (LBD) in a dataset of 56.5 million US Medicare records, and backs it up with animal experiments that show PM2.5 triggers toxic α-synuclein clumps — the protein aggregates that define LBD.
