As per a fairly large study, pollution, especially dirty air can be a significant risk factor in developing dementia.
In one of the largest studies of its kind, researchers looked at data from almost 30 million people and found that long-term exposure to common air pollutants, like car exhaust and industrial fumes, is linked to a higher risk of dementia. These tiny particles in the air can travel deep into the body, and the study suggests they may contribute to memory loss and cognitive decline.
The final analysis included 51 studies and drew from data on over 29 million people, primarily from wealthier nations. Among these, 34 studies were part of the meta-analysis: 15 came from North America, 10 from Europe, seven from Asia, and two from Australia.
The researchers found a positive and statistically significant association between three types of air pollutants and dementia.
- Particulate matter with a diameter of 2.5 microns or less (PM2.5)
- Nitrogen dioxide (NO2)
- Soot

And I completely forget what I wanted say next….. lemme think….. umm, err…, hmmm….,, I remember now: it’s good to know that the EPA will work in overtime to ensure that we will all have clean air to breath.
