Early exposure to air pollution may affect thinking skills later

London, Feb 3 : Parents, take note. If your child is exposed to air pollution, they may have a decline in thinking skills in later life, a study suggests.
The study indicates that greater exposure to air pollution at the very start of life was associated with a detrimental effect on people’s cognitive skills up to 60 years later.
“For the first time we have shown the effect that exposure to air pollution very early in life could have on the brain many decades later,” said co-author Tom Russ from the University of Edinburgh.
“This is the first step towards understanding the harmful effects of air pollution on the brain and could help reduce the risk of dementia for future generations,” Russ added.
For the study, published in the Journal of Alzheimer’s Disease, the researchers tested the general intelligence of more than 500 people, who were a part of Lothian Birth Cohort 1936 study, aged approximately 70 years using a test they had all completed at the age of 11 years.
The test was repeated at the ages of 76 and 79 years.
