A huge new finding about Alzheimer's is totally changing the way we think about our brains and how the deteriorate.
A new study has come to an astonishing conclusion about brains and our risk for dementia, and the alarming role that air pollution plays in that process. The study found that breathing air that is heavily polluted by things like car exhaust can actually double the likelihood of getting dementia later in life, according to a statement from the University of Southern California.
The study examined women between the ages of 65 and 79 and tracked them for 10 years. They found that women who carry a genetic variant known as APOE-e4 had a much higher risk, three times more likely in fact, of developing Alzheimer’s disease when air pollution is introduced into the mix.
Older women who had the gene and were exposed to heavy air pollution were almost four times likelier to get Alzheimer’s than women who breathed cleaner air, the study found. Scientists had long understood a link between air pollution and cardiovascular and lung diseases, it’s now clear that air pollutants have a big impact on the brain as well.
The full statement follows below.
Tiny air pollution particles — the type that mainly comes from power plants and automobiles — may greatly increase the chance of dementia, including Alzheimer’s disease, according to USC-led research.
