Clinical Trial Summary

NMDA neurotransmission plays an important role in learning and memory. NMDA receptors (NMDAR) were found to decrease in the frontal lobe and hippocampus of Alzheimer's disease (AD). This study is a randomized, double-blind, placebo controlled drug trial for testing the efficacy of NMDAR-enhancer. All subjects will be allocated randomly to 4 groups: (1) DAOI-A group; (2) DAOI-B group; (3) DAOI-C group; (4) placebo group. The study period is 24 weeks. The investigators hypothesize that DAOI may yield better efficacy than placebo for cognitive function in patients with AD.
