Study Details

Study Description

Brief Summary

NMDA neurotransmission plays an important role in learning and memory. NMDA receptors were found to decrease in the frontal lobe and hippocampus of mild cognitive impairment. This study is a randomized, double-blind, placebo-controlled drug trial. All subjects will be allocated randomly to 2 groups: (1) NMDA-enhancer: DAOIB group (starting dose: 250-500 mg/d); (2) placebo group. The study period is 24 weeks. The investigators hypothesize that DAOIB may yield better efficacy than placebo for cognitive function in patients with mild cognitive impairment.
