UK study: Air pollution may increase the risk of dementia September 25, 2018 Source: Global Network Author: Wang According to foreign media reports on September 19, a joint study by several universities in London found that there is a correlation between neurodegenerative conditions and microscopic particles exposed to nitrogen dioxide and known as PM2.5, prolonged exposure to air pollution. May increase the risk of dementia. The researchers used an anonymous patient health record from the clinical practice research data link, which came from routine medical care. In 2004, they studied 131,000 patients between the ages of 50 and 79 who did not have dementia. The patients registered 75 routine treatments in the M25. The researchers conducted an average of seven years of follow-up of the health of these patients until they were diagnosed with dementia, died, or left the family doctor's office. The survey found that from 2005 to 2013, a total of 2,181 patients (1.7%) were diagnosed with dementia, 39% of whom had Alzheimer's disease and 29% had vascular dementia. Based on a survey of patients in the vicinity of the patient's residence in 2004, these findings are related to the levels of nitrogen dioxide and PM2.5 in the surrounding environment. Those who live in the five regions with the highest levels of nitrogen dioxide are 40% more likely to be diagnosed with dementia than those living in areas with the lowest levels of nitrogen dioxide. In addition, the same effect on the human level of PM2.5 levels. Regional and urban pollutants may be as important as near traffic pollutants. Last year, studies showed that people living near busy roads were at increased risk of developing Alzheimer's disease and other dementias. Despite this, the cause of neurodegenerative diseases remains unclear, and it is difficult to exclude other explanations. The causes may be multifaceted. It may be that 20 years ago, there were diseases in the brain that caused dementia. Therefore, the interpretation of these findings should be cautious, and there is still much room for research on the link between air pollution and the risk of dementia.
