PM2.5 air pollution linked to memory problems and Alzheimer's-like brain changes
- rajnathani 7y agoAs this is an observational study, there cannot be a causal link established, however there are previous causal links hypothesized as the article states: > Previous research has suggested that fine particle pollution exposure increases the risk of Alzheimer’s disease and related dementias. What scientists haven’t known is whether PM2.5 alters brain structure and accelerates memory decline. And this study, while an observational one, noted significant statistical co-relation: > When all that information was combined, researchers could see the association between higher pollution exposure, brain changes and memory problems — even after adjusting to take into account differences in income, education, race, geographic region, cigarette smoking and other factors.
