Studies Link Wildfire Smoke to Dementia

Researchers are investigating the health and environmental consequences of wildfire smoke as exposure becomes more common. Studies have linked fine particulate pollution, including wildfire-related PM2.5, with dementia risk and more pronounced Alzheimer’s-related brain changes, though scientists are still working to determine how smoke itself and the disruptions caused by fires may contribute. A developing field known as smoke ecology is examining how wildfire smoke affects ecosystems and whether those harms can be prevented or reduced.
