One study looked at people over the age of 51 and found that those who lived in areas with a lot of air pollution had lower cognitive scores than people who had lived in unpolluted areas. The results were normed to take social status and education level into account.
In a second study, conducted at Ohio State University, the research team looked at the effect of pollution particulates in the brain of mice. They found that exposure to pollutants affected the hippocampus- the brain area responsible for learning and memory formation. The exposed mice’s hippocampi had less neuronal growth than those who were not exposed.
Even the London Telegraph reported couple of years back, that the Committee on the Medical Effects of Air Pollutants (COMEAP) had identified as many as 200,000 Britons were exposed to levels of pollution that appeared to shorten their lives significantly–by an average of about two years.
This is a very impotant field of study, and Shirsa is looking forward to seeing additional research findings in this area, as we have many people who identify as suffering from “pollution-related cognitive decline” and seek solutions for improving brain function.
