Researchers at Western University in Canada conducted an extensive meta-analysis to investigate the connection between traffic-related air pollution and dementia. The study's findings indicated that living near a busy road can increase the risk of developing this condition. The analysis, which included data from over 90 million people, revealed that exposure to PM2.5 particles (with a diameter smaller than 2.5 micrometers) was associated with a higher risk of dementia.
According to the researchers, the risk of dementia increases by 3% for every microgram of suspended particles per cubic meter of air on average annually. The study's results emphasize the importance of reducing exposure to traffic-related air pollution and the need for effective policies in this regard. The researchers warn that without a clear strategy and concrete measures, dementia will become an increasingly significant problem in the future.
The findings of this study provide valuable insights into the impact of air pollution on mental health and underscore the urgent need for actions to reduce exposure to pollutants. It serves as a call to action for the implementation of policies and measures aimed at reducing the risk of dementia and protecting public health.
