New York: Experts have conducted meta-studies by re-reading several research surveys and studies. Accordingly, prolonged exposure to air pollution can increase the risk of dementia.

According to the Harvard TH China School of Public Health, there may be a link between specific fine particles in air pollution, or PM 2.5, and dementia. According to the scientists, the research not only clarifies the link between air pollution and dementia, but also paves the way for environmental organizations and institutions to legislate to curb PM2.5 particles.

Professors Mark Wyskov and Philip Drinker, who were involved in the research, say the research also suggests a viable approach to public health. The ROBINS-E tool and its protocols have also been used in its assessment. Which stands for ‘Risk of Bias in Non-Randomized Studies of Exposure’. This allows environmental issues to be looked at in depth.

The research is included in a recent publication of the British Medical Journal. In this context, experts have painstakingly reviewed a total of 2,000 studies and 51 have revealed that there may be a link between air pollution and dementia. All the investigations came to light in the last ten years. Experts also noted that even if the level of PM 2.5 in the atmosphere is low, its harmful effects persist. That is, if PM 2.5 particles increase slightly from 12 micrograms per cubic meter to the prescribed harmless amount, brain damage starts. If PM 2.5 increases by two percent, the risk of dementia jumps to 17 percent. Air pollution can increase the risk of dementia.

Scientists have said in the proposals that it is important to focus on reducing air pollution, including carbon dioxide and PM 2.5.
