Study design:

Cohort study 

研究目的:

1、建立可早期识别脑白质高信号合并认知障碍的肠道菌群与代谢的多组学标志物体系。  2 、明确脑白质高信号认知障碍患者认知功能恶化的预警标记物,实现早期识别脑白质认知功能恶化的高危风险人群,精准预防。 3、明确菌群-代谢-血脑屏障的内在关联及潜在机制。  

Objectives of Study:

1.Establish a multi-omics marker system of gut microbiota and metabolism that can identify white matter hypersignaling combined with cognitive impairment at an early stage. 2. Identify the early warning markers of cognitive function deterioration in patients with high-signal cognitive impairment in white matter, and achieve early identification of high-risk factors for cognitive function deterioration in white matter For people at risk, precise prevention is essential. 3. Clarify the intrinsic correlation and potential mechanisms among the microbiota, metabolism, and blood-brain barrier.
