A new study has proved that the risk of problems related to mental health in elder people increases with air pollution.
According to German researchers, who conducted the study, women who had their residences near busy roads for a period of 20 or more years, showcased more mild cognitive impairment, which is the initial stage of dementia.
The study conducted by Heinrich-Heine University in Dusseldorf gathered data on the levels of air pollution and the women’s addresses from distances from busy roads that carried more than 10,000 cars a day.
The study proved that women below 74, who had their residences near busy roads, showcased the worst performances in the cognition tests.
"These results indicate that chronic exposure to traffic-related PM may be involved in the development of mild cognitive impairment and since mild cognitive impairment is a transition state between normal ageing and dementia, more research should be conducted with these women," the Telegraph quoted the research paper as saying.
The study belies that the minute particles present in air enter the brain via lungs, leading to the inflammation of the bran, which in turn triggers dementia.
