研究目的: |
本研究结合影像学指标诊断为脑小血管病的患者,收集参与者的基本信息和认知水平,检测血中反映营养状况的相关指标。分析营养状况与脑小血管病认知障碍发生的关联,并探讨其可能的机制,为叶酸对脑小血管病患者的防治和脑小血管病认知障碍改善作用提供依据。 |

Objectives of Study: |
This study combines imaging indicators to diagnose patients with cerebral small vessel disease, collects basic information and cognitive levels of participants, and detects relevant indicators reflecting nutritional status in the blood. Analyze the correlation between nutritional status and cognitive impairment in patients with cerebral small vessel disease, and explore its possible mechanisms, providing a basis for the prevention and treatment of cerebral small vessel disease with folic acid and the improvement of cognitive impairment in patients with cerebral small vessel disease. |
