Wildfire Smoke Linked to Increased Dementia Risk

New research indicates that long-term exposure to wildfire smoke may be more harmful to brain health than other types of air pollution.

Studies show a 21% increase in dementia risk for every microgram per cubic meter of fine particulate matter from wildfire smoke.
Wildfire smoke's tiny particles can cross the blood-brain barrier, causing inflammation and cognitive decline.
The frequency and intensity of wildfires are rising due to climate change, expanding smoke exposure.
Experts recommend using air filters and N95 masks to mitigate exposure during poor air quality days.
Research highlights the need for community strategies to protect vulnerable populations from the health impacts of wildfire smoke.
