摘要
观察研究结果表明，老年人血浆同型半胱氨酸浓度与认知功能呈逆相关。本研究试图检验这一假设，确定降低血浆同型半胱氨酸浓度是否可改善健康老人的认知功能。
Some observational studies suggest that plasma homocysteine concentrations are inversely related to cognitive function in older people. This study tried to test the hypothesis that lowering the plasma homocysteine concentration improves cognitive function in healthy older people.
