In the latest issue of Vitality, USC Leonard Davis School of Gerontology's magazine, the cover story was all about how the environment impacts how we age.
Though Los Angeles has improved its air quality there are still many pollutants in the air that effect our health.
The studies discussed in the article found that women who live in areas with levels of "fine particulate matter" above the standard defined by the U.S. EPA are 81% more at risk for cognitive decline and 92% more likely to develop dementia.
The particles we breath in through the nose go directly into the brain where the brain cells treat the particles as invaders, causing inflammation, which over time can "exacerbate and promote Alzheimer's disease," stated Professor Finch, one of the co-senior authors of the study.
This study is the first of its kind in the U.S. and there is a big push for more research in this area to confirm this studies findings and hopefully begin to find some solutions to the issue.
The article points out that there are nearly 48 million people worldwide suffering from dementia, Alzheimer's disease being the most common form. This is a global issue, as air pollution does not have any borders, so what one country, state, county, does can effect us all.
They included a short video to explain some of the studies findings.
Below the video is also a link to the full magazine online. Lots of great articles on current research. ENJOY!
