新研究：长期暴露于空气污染中或增加罹患渐冻症风险

Core Findings - A new study from the Karolinska Institute in Sweden indicates that long-term exposure to air pollution may increase the risk of motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), and accelerate the disease's progression [1][2] Group 1: Study Overview - The study involved 1,463 confirmed patients with motor neuron diseases, assessing air pollution levels in their residences over the longest period of 10 years prior to diagnosis, focusing on PM2.5, PM10, and nitrogen dioxide concentrations [1] - Two control groups were established: 1,768 siblings of the patients and over 7,000 matched controls from the general population for comparative analysis [1] Group 2: Key Findings - Long-term exposure to air pollution, even at low concentrations, increases the risk of developing motor neuron diseases by 20% to 30% [2] - Patients living in areas with higher air pollution levels experience faster deterioration in motor and lung functions post-diagnosis, are more likely to require invasive ventilation, and have a higher mortality risk [2] - The study confirms previous findings that air pollution can lead to neuroinflammation and oxidative stress, establishing a link between air pollution and motor neuron diseases, although the underlying mechanisms remain unclear [2]
