And here: Air pollution in towns and cities ‘ages brains of over-50s by three years’(MailOnline, Nov. 16, 2012)
Today’s feature review article takes a new look at the impact of air pollution on how well people over 50 think after analyzing tests assessing word recall, knowledge, language, and orientation. The results indicate that an increase of 10 micrograms/cubic meter of fine particulate matter (roughly the difference between living in a typical built-up cities to living in rural areas) translates into an additional aging of 3 years. This comes in addition to the other well documented effects of air pollution on health which shorten life expectancy (by 7-8 months in the UK for example). This prompts one to consider if the rise in dementia and Alzheimer’s might also be associated this in urban areas, along with the large increase in the population of seniors in many countries.
