Air pollution may be to blame for thousands of dementia cases each year, researchers say
Nearly 188,000 dementia cases in the U.S. each year may have been caused by air pollution, researchers estimate, with bad air quality from wildfires and agriculture showing the strongest links to a person's risk of Alzheimer's disease and other kinds of dementia later in life. Published Monday in the journal JAMA Network Open, the new estimates are the latest to underscore the range of health risks scientists have long warned are being driven by air pollution. While studies have already linked overall bad air quality to a number of health problems, including the risk of developing dementia, the new study offers a finer-grained look at how specific causes of air pollution seem to be more strongly linked to dementia than others.
