研究目的:

(1)探索ALA 与 MCI 患病风险及发病风险的量效关系。 (2)探索ALA 干预对 MCI 人群认知功能的影响。 (3)探索ALA 能否通过调节肠道菌群及其代谢产物进而发挥改善认知功能的作用。  

Objectives of Study:

(1) To explore the quantitative and qualitative relationship between ALA and the risk of MCI and the risk of morbidity. (2) To explore the effect of ALA intervention on cognitive function in MCI population. (3) To explore whether ALA can improve cognitive function by regulating intestinal flora and its metabolites.
