Study of 28 Million Americans Links Air Pollution Directly to Alzheimer's
A nationwide study of nearly 28 million older Americans found fine particulate pollution directly raises Alzheimer's risk, with prior stroke increasing vulnerability, researchers said.
- Emory University research team found long-term PM2.5 exposure is linked to higher Alzheimer's risk after analyzing health records of more than 27.8 million US citizens aged 65 and older in a PLOS Medicine study.
- To test whether particle pollution acted indirectly, the researchers designed the study to see whether PM2.5 raises Alzheimer's indirectly by causing high blood pressure, stroke or depression.
- The analysis showed PM2.5 exposure was linked to increased Alzheimer's risk mainly through direct pathways, and people who previously had a stroke faced slightly higher vulnerability among nearly 3 million Alzheimer's cases.
- Because disadvantaged communities face higher exposure, the study noted that individual choices cannot offset long-term effects and urged stricter air-quality standards to reduce Alzheimer’s risk.
- The authors cautioned that this observational study used estimated outdoor exposure at ZIP-code level and did not include indoor and workplace exposure; future research may focus on mechanistic investigations.

Exposure to air pollution increases the risk of developing Alzheimer's disease, according to a major new study from Emory University in Atlanta.
Air pollution remains a major public health problem, and a new study suggests that the impact is also on brain health. People exposed to higher levels of pollution have a greater risk of developing Alzheimer's disease, according to an extensive research carried out in the United States.
People exposed to higher levels of air pollution have a higher risk of developing Alzheimer's disease, a new study has found. Air pollution has long been considered a risk factor for Alzheimer's disease and several common chronic health conditions, such as hypertension, stroke and depression, Euronews reports.
Air pollution linked to higher Alzheimer’s risk in 28 million older Americans
Breathing polluted air may do more than harm your lungs — it could also increase your risk of Alzheimer’s disease. In a sweeping study of nearly 28 million older Americans, researchers found that long term exposure to fine particle air pollution was linked to a higher likelihood of developing Alzheimer’s. The connection appeared to stem largely from pollution’s direct effects on the brain, rather than through related health conditions like hyper…
