新加坡的一项研究发现,MRI上扩大的脑流体空间可能预示早期阿尔茨海默氏症。 Enlarged brain fluid spaces on MRI may signal early Alzheimer’s, a Singaporean study finds.

新加坡的一项研究将扩大的围内空间(EPVS)与早期阿尔茨海默氏病联系起来。 A Singaporean study links enlarged perivascular spaces (EPVS)—fluid-filled areas around brain blood vessels, likened to "clogged drains"—to early Alzheimer’s disease. 研究人员对近1 000名参与者进行了分析,发现有轻度认知障碍的人的EPVS比其他人多。 Analyzing nearly 1,000 participants, researchers found those with mild cognitive impairment had more EPVS than others. 这些空间是大脑废物清理系统的一部分,使用标准的磁共振扫描扩大这些空间可能预示早期阿尔茨海默氏症,并有可能促成早期诊断和干预。 These spaces are part of the brain’s waste-clearance system, and their enlargement on standard MRI scans may signal early Alzheimer’s, potentially enabling earlier diagnosis and intervention. 调查结果表明,欧洲PVS可以提供一种非侵入性、无障碍的工具,在疾病大幅下降之前能够发现该疾病。 The findings suggest EPVS could offer a non-invasive, accessible tool for detecting the disease before significant decline.
