Studies Link Air Pollution to Brain Health Risks Including Dementia and Stroke

Pollutants from sources such as vehicle emissions, wildfires, and crop burning can enter the body, causing inflammation and damaging blood vessels. Experts emphasize that air pollution's impact extends beyond respiratory issues, affecting cardiovascular and neurological systems, with growing concern amid worsening environmental conditions.
