Polluted air attacks the brain, study finds strong link to Alzheimer's disease
People exposed to higher levels of air pollution during their lives have a higher risk of developing Alzheimer's disease, a new study by Emory University in the United States has shown, emphasizing that air pollution acts directly on the brain, not indirectly through chronic diseases such as hypertension, stroke, and depression, which also represent risk factors for dementia.
TL;DR
- Higher exposure to air pollution during life increases Alzheimer's risk.
- Air pollution directly impacts the brain.
- This direct effect is independent of chronic diseases like hypertension, stroke, and depression.
- These chronic diseases are also known risk factors for dementia.
