研究显示改善空气质量或有助于预防阿尔茨海默病

Core Viewpoint - Long-term exposure to severe air pollution is associated with an increased risk of Alzheimer's disease, suggesting that improving air quality may help in preventing the disease [1] Group 1: Research Findings - A study published in the journal PLOS Medicine analyzed data from over 27.8 million patients aged 65 and older in the U.S. from 2000 to 2018 [1] - The study found a stronger association between severe air pollution exposure and Alzheimer's risk in individuals who had previously suffered a stroke [1] - High blood pressure and depression had a smaller impact on the association between air pollution and Alzheimer's disease [1] Group 2: Implications - The findings indicate that air pollution may directly affect the brain, leading to Alzheimer's disease rather than through common chronic diseases like high blood pressure, stroke, or depression [1] - The research suggests that improving air quality could be a strategy for preventing Alzheimer's disease in the elderly population [1]
