摘要目的 随访观察老年轻度认知功能损害(MCI)患者认知水平的变化特点.方法 以2008年某军队干休所MCI患者47例及正常对照21名为研究对象,随访一年,在初次确诊以及一年后分别进行蒙特利尔认知评估表(MoCA)中文版、简易精神状态检查表(MMSE)和画钟测验(CDT)等神经心理评估.结果 随访一年后,MCI组MMSE量表总分、MoCA量表总分及视空间、延迟回忆分项得分和CDT得分与基线得分比较均有不同程度下降,其中MoCA量表总分及延迟回忆分项得分随访后与基线间差异有统计学意义(P=0.041,P=0.003);正常对照组MoCA量表总分、定向力、视空间、延迟回忆分项得分以及CDT得分也有不同程度下降,但差异无统计学意义.结论 延迟回忆受损是老年MCI患者认知水平变化的早期特征性表现.

abstractsObjective To observe and assess the cognitive changes of mild cognitive impairment (MCI) in the elderly. Methods A cohort study design was conducted among 47 patients with MCI and 21 control selected from the same convalescent camp, Montreal cognitive assessment ( MoCA ), mini mental state examination (MMSE)and clock drawing test (CDT) were performed to all subjects at the onset of study and 12 months later. Results The score of MMSE, CDT, MoCA and its subitems including visuospatial skill and delayed recall of MCI group were lower than the baseline afer12 months, with significantly decline in the score of MoCA( P= 0. 041 )and delay recall (P = 0. 003 ). There was no obvious difference in the score of control between the baseline and that afer12 months. Conclusion The decline of delayed recall occurred early and significantly, which may be a predictor in the conversion of mild cognitive impairment to dementia.
