New Research Shows That This Doubles the Risk of Dementia

There are many factors that can be linked to dementia, such as age, genetics, and lifestyle choices. But researchers recently discovered something else that they believe could double the risk of dementia.

Air pollution

According to research from the University of Southern California, there are environmental factors that can contribute toward developing dementia. One is air pollution. The air is polluted with particles that come from automobiles and factories. These particles enter our lungs and blood stream. Researchers believe these particles could be responsible for about one out of every five cases of dementia.

The study included women age 65 - 79 from different parts of the country; none of them had any signs of dementia. The study tracked data from 1999 through 2010 on the women involved and found that those who were exposed to higher levels of air pollution had faster rates of cognitive decline and a higher risk of developing dementia. Researchers next want to study men to determine if they have the same risk of dementia as women.

Other risk factors

People who have other factors linked to dementia, such as genetics, smoking, obesity, diabetes, high blood pressure, clogged arteries, and excess drinking or have a high-risk gene for Alzheimer’s disease, APOE4, will have an even greater risk of dementia, up to 2-3 times greater.
