Air pollution promotes inflammation in brain, accelerates cognitive decline and increases risk of dementia: Study
Results from new study suggests that long-term exposure to air pollution leads to increased risk in dementia in Denmark.
"We also find association with noise, but this seems to be explained by air pollution primarily. Our study is in line with growing international knowledge on this topic." says Professor at Section of Environmental Health Zorana Jovanovic Andersen.
This is an important finding which adds that air pollution, beyond well-known effects on respiratory and cardiovascular system, also has major impacts on our brain, promoting inflammation in the brain, accelerating cognitive decline, and increasing risk of dementia.
"This is the first study in Denmark showing a link between air pollution and dementia. Although air pollution levels in Denmark have been declining and are relatively low, compared of the rest of Europe and world, this study shows that there are still significant and concerning health effects that demand more action and policies towards reduction of air pollution. As we are going to live longer, and more and more people will be diagnosed with dementia, this finding is important as it offer an opportunity to prevent new dementia cases, and ensure more healthy aging, by cleaning up the air we breathe," says Zorana Jovanovic Andersen.
