摘要：

      摘要 目的：对脑血管病非痴呆患者进行现实理解时钟测验（RCCT）的结果进行分析，并与正常人组进行比较，初步了解RCCT在血管性认知损害筛检中的作用。 方法：运用RCCT与简明精神状态量表（MMSE）两种测验方法对20例脑血管病非痴呆患者及年龄、受教育年限相匹配的20例正常人组被试进行评估,分析RCCT与MMSE得分之间的差异。 结果：脑血管病非痴呆组的RCCT得分明显低于正常人组（P＜0.01）；正常人组年龄、文化程度与RCCT得分无明显相关性（P＞0.05）；正常人组显示年龄与MMSE得分呈高度负相关（P＜0.01）,受教育年限与MMSE得分呈正相关（P＜0.05）；所有RCCT测试时间均在15min/次以内。 结论:RCCT作为一种标准化的简便的认知功能检测工具，对血管性认知损害有一定的筛检作用；RCCT成绩在正常成人中受年龄、文化程度的影响可能较MMSE成绩所受到的影响要小。建议RCCT可与MMSE同时应用于血管性认知损害的筛检。

Abstract:

      Abstract Objective： To ensure the advantages of reality comprehension clock test(RCCT) as a screening method by comparing RCCT with mini mental state examination(MMSE) in screening patients with vascular cognitive impairment-no dementia（VCIND）. Method： The cognitive function of 20 cerebral vascular disease(CVD) patients and 20 normal persons were evaluated by RCCT and MMSE. The RCCT and MMSE scores of two groups were compared. Result: There was significant difference in RCCT scores between CVD patients and normal persons（P＜0.01）. RCCT scores had no correlation with age and education of normal people（P＞0.05）. For normal persons, MMSE scores had a great negative correlation with age and（P＜0.01）and a positive correlation with education（P＜0.05）. RCCT was needed to take less than 15 min for the evaluation in each patient. Conclusion：RCCT is a good screening method to evaluate the cognitive function of CVD patients. MMSE scores are easily affected by age and education factors. Age and education factors are no effect on RCCT scores.
