根据一项新的研究,长期受到空气污染,即使是在低水平,也会增加运动神经元疾病的风险和速度。 Long-term exposure to air pollution, even at low levels, increases risk and speeds progression of motor neurone disease, according to a new study.

JAMA神经学的一项新研究将长期遭受空气污染(即使在瑞典典型的低水平)与包括ALS在内的运动神经元疾病(MND)的20%至30%的较高风险以及更快的疾病蔓延联系起来。 A new study in JAMA Neurology links long-term exposure to air pollution—even at low levels typical of Sweden—to a 20–30% higher risk of motor neurone disease (MND), including ALS, and faster disease progression. 研究人员对来自10 000多人的数据进行了分析,发现在诊断前10年,在家庭附近接触PM2.5、PM10和氮氧化物等污染物与风险增加、早期需要呼吸系统支持和死亡率提高有关。 Analyzing data from over 10,000 individuals, researchers found that exposure to pollutants like PM2.5, PM10, and nitrogen dioxide near homes up to ten years before diagnosis was associated with increased risk, earlier need for respiratory support, and higher mortality. 在对遗传学和共同环境进行核算之后,这种联系仍然存在,这表明当地交通污染可能发挥关键作用。 The connection remained after accounting for genetics and shared environments, suggesting local traffic-related pollution may play a key role. 虽然这项研究不能证明因果关系,但它补充了空气污染损害神经系统健康的证据,并强调清洁空气对疾病预防的重要性。 While the study cannot prove causation, it adds to evidence that air pollution harms neurological health and underscores the importance of cleaner air for disease prevention.
