摘　　要：目的探讨蒙特利尔认知评估量表（Montreal Cognitive Assessment，MoCA）对短暂性脑缺血发作（transient isehemie attack，TIA）患者认知功能损害评估的意义。方法选择61例临床诊断为TIA的患者，在其最后一次发作的72h内应用MoCA及简易智力状态量表（Mini—mental State Examination，MMSE）检测其认知功能，与40例健康体检人员进行对照比较。结果TIA组的MoCA总评分、MMSE总评分[分别为（16．59±5．74）分，（20．80±4．20）分]低于健康体检对照组[分别为（27．58±1．36）分，（27．69±2．00）分]，差异具有显著性（P〈0．01）；TIA患者的MoCA和MMSE总评分随TIA发作次数增加而降低，TIA患者的MoCA总评分与MMSE总评分呈显著性正相关r=0．777，P〈0．01），且相关系数随发作次数增加而增高；MoCA对TIA认知障碍诊断的敏感性、诊断效率（分别为86．89％、90．10％）高于MMSE（分别为67．21％、79．21％），差异具有显著性（P=0．010、P=0．032）。结论MoCA量表测试可以反映TIA认知功能损害的临床特征，可作为TIA患者认知功能受损筛查的良好工具，其应用价值优于MMSE。Objective To evaluate the clinical significance of Montreal cognitive assessment （MoCA） in detecting cognitive impairment in patients with transient ischemic attack（TIA）. Methods Sixty-one patients with transient ischemic attack in seventy-two hours and forty healthy individuals were assessed with MoCA and Mini- mental State Examination. Results The MoCA scores（ 16.59 ±5.74） and MMSE scores （20.80 ± 4.20 ） of the TIA group were obviously lower than that of the control group（ 27.58 ± 1.36,27.69 ± 2.00, respectively P 〈 0. 01 ）. With the increase of attack times,the MoCA scores and MMSE scores decreased gradually. The correlation analysis indicated that there was a positive correlation between MoCA and MMSE in patients with TIA（r = 0. 777, P 〈 0.01 ）. With the increase of the frequency of attack, the correlation coefficient advanced gradually. The sensitivi- ty （86.89%） and diagnostic effect （90.10%） of MoCA were obviously higher than that of MMSE（P = 0. 010, P = 0. 032,respectively） in TIA diagnosis. Conclusion The TIA patients exist cognitive dysfunction, and MoCA may be a better measure to evaluate the cognitive dysfunction in patients with TIA than MMSE.
