The term “dementia” refers to a variety of mental diseases, particularly in older adults, that affect thinking, memory, and everyday functioning. Dementia risk factors include old age, hypertension (high blood pressure), smoking, inactivity, social isolation, and depression.
According to a recent research, exposure to nitrogen dioxide and nitrogen oxide, as well as air pollution, all raise the risk of dementia. It is important to use care when interpreting the BMJ conclusions, which point to air pollution as dementia risk factors.
Almost 57 million individuals now live with dementia, and that figure is steadily increasing. No firm results were formed since there aren’t many strategies that can be used to delay or halt dementia’s development.
The purpose of the research was to address the rising number of dementia sufferers. They found 51 papers linking adult dementia diagnoses with air pollution exposure on average over a year or longer.
After combining 16 papers—mostly from North America and Europe—the researchers discovered a link between greater exposure to fine particle pollution and an increased risk of dementia.
The incidence of dementia rose by 4% for every 2 ug/m3 rise in the average annual PM2.5 concentration, according to 14 research that focused on the effect of PM2.5 on dementia.
According to the findings, the risk of dementia rose by 42% for every 2 ug/m3 rise in the average annual PM2.5 concentration, with the most conservative estimate placing the risk at greater than 17%. The research asserted that exposure to nitrogen dioxide and nitrogen oxide increases the risk of dementia.
The study, however, was unable to identify a link between ozone and dementia.
Since it will have a good effect on dementia and other climate change concerns, lowering air pollution is crucial for humanitarian and global health reasons.
