Exposure to wildfire smoke could increase the risk of dementia, researchers have discovered.A 10-year study of more than 1.2 million people in southern California — an area experiencing frequent wildfire activity — found that wildfire smoke can be “particularly hazardous” for brain health.The Alzheimer’s Association announced the findings during the Alzheimer’s Association International Conference in Philadelphia on Monday.ALZHEIMER’S BLOOD TEST DETECTS DISEASE WITH 90% ACCURACY IN ROUTINE DOCTORS’ APPOINTMENTS: STUDYThe study found that wildfire smoke increases dementia risk more than other types of air pollution, including emissions from motor vehicles and factories called fine particle matter (PM2.5), according to a press release from the Alzheimer’s Association. A 10-year study of more than 1.2 million people in southern California — an area experiencing frequent wildfire activity — found that wildfire smoke can be “particularly hazardous” for brain health.

Researchers analyzed the health records of 1,227,241 southern Californians, none of whom had been diagnosed with dementia at the start of the study. (iStock)Dr. Claire Sexton, senior director of scientific programs and outreach for the Alzheimer’s Association, told Fox News Digital that exposure to air pollution is known to be bad for brain health, as previous reports have linked PM2.5 to dementia.”Each year, approximately 44 million people are exposed to unhealthy air quality due to wildfires worldwide.” Improving air quality could help to protect cognitive function and reduce dementia risk, according to Sexton. “Each year, approximately 44 million people are exposed to unhealthy air quality due to wildfires worldwide,” she said. “Wildfires are increasing around the globe in frequency, severity and duration.”AMID CONCERNS ABOUT BIDEN’S MENTAL ACUITY, EXPERTS REVEAL HOW COGNITIVE TESTS WORK AND WHAT THEY REVEALThis new study highlighted several reasons that wildfire smoke is more dangerous, Sexton said.Wildfire smoke is produced at higher temperatures and contains a greater concentration of toxic chemicals compared to other forms of air pollution, she noted.

To lower the risk of exposure, Sexton recommends that people update their home air filtration systems and stay inside during periods of unhealthy air quality.CLICK HERE TO GET THE FOX NEWS APPResearchers also suggest wearing an N95 mask outdoors when the Air Quality Index is over 100.
