Air Pollution Linked To Dementia - CleanTechnica

The article from CleanTechnica discusses the emerging evidence linking air pollution, particularly fine particulate matter (PM2.5), to an increased risk of dementia and accelerated cognitive decline. Air pollution, often invisible and composed of tiny particles from sources like vehicle exhaust, coal power plants, and industrial emissions, can cause harmful health effects that are not always immediately noticeable. Recent human studies, including research published in JAMA Neurology, have shown that long-term exposure to PM2.5 is associated with greater dementia risk, more pronounced Alzheimer’s disease-related brain changes, and faster deterioration in cognitive function and daily living abilities among those already diagnosed. The article emphasizes that air pollution contributes to systemic inflammation, oxidative stress, and small-vessel damage, which exacerbate neurological outcomes and increase complications such as loss of independence and falls. It highlights the importance of recognizing environmental exposure as a significant factor in dementia severity for public health planning and individual protection. CleanTechnica also connects this issue to the broader context of transitioning away from
