2026年的一项研究将长期接触细空气污染与65岁以上美国人阿尔茨海默氏病的风险增加联系起来,这表明脑部受到直接伤害。 A 2026 study links long-term exposure to fine air pollution with increased Alzheimer’s risk in Americans over 65, suggesting direct brain harm.

2026年埃默里大学对超过2700万65岁及以上的美国人进行的一项研究将长期暴露于微量空气污染 (PM2.5) 与阿尔茨海默病的风险更高联系起来,这表明直接影响大脑而不是通过其他健康状况间接影响. A 2026 Emory University study of over 27 million Americans aged 65 and older links long-term exposure to fine air pollution (PM2.5) with a higher risk of Alzheimer’s disease, suggesting direct brain impacts rather than indirect effects through other health conditions. 这项研究以2000年至2018年《医疗保健计划》的数据和环境污染水平为基础,发现前中风患者的联系更加紧密,并表明污染可能损害血液脑部屏障,加速大脑老龄化,增加痴呆症风险。 The research, based on Medicare data and environmental pollution levels from 2000 to 2018, found stronger associations in people with prior strokes and indicates pollution may damage the blood-brain barrier, accelerate brain aging, and increase dementia risk. 虽然这项研究不能证明因果关系,但它增加了越来越多的证据,表明空气质量在神经退化中起着作用,支持公共卫生努力减少对脑健康的污染。 Though the study cannot prove causation, it adds to growing evidence that air quality plays a role in neurodegeneration, supporting public health efforts to reduce pollution for brain health.
