Can breathing lead to Alzheimer’s? Three studies of the link between air pollution and dementia suggest that it could. Exceedingly small polluting particles — 200 times smaller than the width of a human hair — of ammonium, black carbon, nitrate, sulfate, and heavy metal are known to cause or exacerbate asthma, lung cancer, heart disease — and now — dementia, including Alzheimer’s.
Here is a link to a Science Magazine article discussing two of the studies and the general broad problem:

Below are links to groups of media articles discussing each study, each together with a link to the research article.
