Alzheimer’s and dementia rates are skyrocketing, leaving many people wondering what the root cause could be. The answer may be lurking in the very air we breathe! Air pollutants, including particulate matter air pollution, could be contributing to the disturbing spike in cognitive decline and Alzheimer’s cases.
Air pollutants consist of particles like dust, dirt, soot, and smoke, as well as smaller particles that are invisible to the naked eye. These particles come from various sources like construction sites, unpaved roads, fields, smokestacks, and fires. Power plants, industrial factories and automobiles are also major sources. As expected, this dangerous form of pollution is higher in urban areas, meaning residents in these areas may be at a higher risk of Alzheimer’s and dementia.
Alzheimer’s-Causing Air Pollutants
Researchers at the University of Southern California found that older women exposed to higher levels of particulate matter air pollution were 81% more likely to develop cognitive decline and 92% more likely to develop Alzheimer’s or dementia. Furthermore, women carrying the APOE e4 gene were found to be even more sensitive to the effects of air pollution. Based on their findings, researchers estimate that particulate matter air pollution could be responsible for as many as 21% of dementia cases in the United States.
The effects of air pollution on the brain may be linked to how the particles enter, primarily through the nose. This triggers an inflammatory response, which in turn plays a significant role in the development of Alzheimer’s. Exposing the brain to additional inflammation-causing agents could be the tipping point that sends cognitive health into a downward spiral.
Solutions to the Air Pollution Dilemma
While environmental health risks such as air pollution may seem impossible to avoid, the truth is, there are steps that can be taken to reduce exposure. Some recommended actions include:
- Check your local air quality index and minimize outdoor time when air quality is poor.
- Try to avoid walking or sitting in heavy traffic whenever possible.
- Set your car’s fan to “recirculate” when stuck in traffic to prevent auto exhaust from entering the vehicle.
- Improve indoor air quality by purchasing air-purifying plants, using a vacuum with a HEPA filter, or investing in an indoor air purifier.
In addition to taking precautionary measures against air pollution, there are other ways to reduce Alzheimer’s risk. Some suggestions include:
- Eat foods known to boost brain health and preserve memory.
- Incorporate Alzheimer’s-fighting herbs and spices, such as turmeric and cinnamon, into your diet.
- Engage in regular physical exercise.
- Harness the brain-healing powers of coffee.
- Take advantage of the brain protection offered by B-vitamins.
In Conclusion
While alarming rates of Alzheimer’s and dementia continue to increase, there are effective ways to reduce the risks. Taking action to reduce air pollution exposure and engaging in other healthful activities are imperative steps in the prevention of these devastating brain diseases. As with many health issues, it is essential to remain proactive, seeking ways to improve overall health and reduce the chances of developing severe cognitive decline and Alzheimer’s.
