Improving Air Quality Reduces Dementia Risk – Studies

Improving air quality may improve cognitive function and reduce dementia risk, according to several studies reported at the Alzheimer’s Association International Conference® (AAIC®) 2021 in Denver and virtually.

Previous reports have linked long-term air pollution exposure with accumulation of Alzheimer’s disease-related brain plaques, but this is the first accumulated evidence that reducing pollution, especially fine particulates in the air and pollutants from the burning of fuel, is associated with lower risk of all-cause dementia and Alzheimer’s disease.

Both increasing levels of air pollution and increasing cases of dementia are worldwide public health crises. While research has linked air quality and cognition previously, these new data at AAIC 2021 explore how air pollutants might impact dementia and what reducing them might mean for long-term brain health.

Among the key findings are:

Solar-powered cycling paths and more coming … Harvard

As a daily bike rider here in Chicago, I was thrilled to learn of the advancements for cyclists overseas reported by Harvard.

Solar-powered bike paths that can melt snow and ice; pollution-eating vacuum towers near bicycle paths; bicycle parking stations with lockers, rest rooms, and showers; and bicycle wheels with rechargeable batteries that help propel riders up hills are just a few of the 70 innovations—some already in place, others still on the drawing board—outlined in a new compilation of inventive ideas aimed at encouraging people to bike. “Promoting Bicycling Through Creative Design: Innovations for Bicycles and Cycling Facilities” was compiled by Anne Lusk,  research scientist in the Department of Nutrition, in partnership with the U.S. Environmental Protection Agency and the League of American Bicyclists, with support from the Helen and William Mazer Foundation.

In a podcast, Lusk talks about ways to make biking safer and easier.

“The hope is that these innovations will move the needle faster in getting people to take up cycling,” said Lusk. There are lots of good reasons for doing so, she said, noting that bicycling is good for people’s health and good for reducing greenhouse gas emissions. It may also boost local economies, she said. She cited a 2010 study of a retail area in Melbourne, Australia that found that $31 was generated per hour for each square meter of parking allotted to bikes compared with $6 for similar space allotted to cars—because bikes take up so much less space than cars, thus allowing for more shoppers in the area.
