Breathing polluted air could damage the memory and age the brain by 10 YEARS in the worst affected areas, study warns

People living in polluted parts of England can expect to be more forgetful as scientists draw a link between high levels of pollutants and memory loss. 

Researchers from the University of Warwick found that human memory is significantly worse in areas with high levels of nitrogen dioxide (NO2) and air particulates (PM10).

Comparing the memory of those living in England’s most-polluted areas with those in the cleanest air found that those breathing in more pollutants had the memory loss equivalent to someone 10 years older than them in the clean area.

The same result had been found in a prior smaller-scale laboratory research on rats and other animals.

But the new research, by professors Nattavudh Powdthavee and Andrew Oswald, is some of the first to confirm the same in humans.

The researchers examined 34,000 English citizens randomly sampled from across England’s local-authority districts.

Everyone in the study was asked to remember 10 words in a standardised word-recall test.
