研究：脑血管功能变化可能与阿尔茨海默病风险相关

Core Insights - A new study in the United States indicates that vascular function in the brain declines before the noticeable symptoms of Alzheimer's disease appear, suggesting that simple, non-invasive vascular examinations could be used for large-scale screening to identify high-risk populations for Alzheimer's disease [1] Group 1 - Alzheimer's disease is the primary type of dementia, and its underlying pathological processes can begin decades before the onset of symptoms [1] - Declines in brain vascular function and insufficient oxygen and nutrient supply to brain tissue may be among the earliest pathological changes associated with Alzheimer's disease [1]
