Wearing face masks could protect against dementia risk , study suggests

Face masks could be recommended to protect against dementia in the wake of new research. Experts have advised the use of masks to filter out dirty air – as well as Covid-19 – following a US study which linked pollution to dementia. Older people living in areas with a small amount of extra pollution had a 16 per cent higher risk of developing dementia, according to the research from the University of Washington. The study, of more than 4,000 people over the age of 65, looked at small pollution particles called PM2.5, which tend to come from cars and heavy industry.

Small increases in air pollution from tiny toxic particles can raise the risk of dementia

A small increase in fine particle air pollution raises dementia risk by 16%, a new study finds University of Washington researchers used decades worth of data from long-running projects on dementia risk and air pollution In addition to dementia risk, they found small air pollution increase raised Alzheimer s risk by 11% Improving air quality could be a key strategy for reducing these conditions, the researchers say 

Higher air pollution exposure linked to increased dementia risk, study suggests

By Press Association 2021 Higher levels of air pollution have been linked to a higher risk of dementia (Stefan Rousseau/PA) Exposure to high levels of air pollution over a decade is associated with an increased risk of developing dementia, according to a long-running study. Researchers said their ability to estimate exposures over 40 years in a specific area made their work “unprecedented” and “unique”. The study, led by the University of Washington, found that just a slight increase in the levels of fine particulate matter – PM2.5 – over a decade at specific addresses in Seattle in the US was associated with a greater risk of dementia for people living there.
