PM2.5 may accelerate changes linked to Alzheimer’s disease
PM2.5 particles in polluted air may affect the brain and speed up changes linked to Alzheimer’s disease.
The particles can come from vehicle exhaust, factory smoke and Asian dust.
The concern is that people may breathe them in without noticing.
The particles may accelerate Alzheimer’s-related changes, though the wording describes a possibility, not a certainty.
The connection matters because it suggests air pollution could be relevant to dementia risk.
A medical professor explains recent findings and possible steps people can take, but the specific steps are not included here.
