摘　　要：目的探讨不同CDT评分系统在筛查认知功能障碍中的效能。方法在苏州市立医院本部相关科室收治的老年患者中选择确诊为MCI的患者75例,以及健康对照组80例,在接受平衡测试后由受专业指导的医师对两组患者进行画钟测验(CDT),随后以不同的CDT评分系统对结果进行评分,并根据各自评分系统的划界分来筛查MCI。结果总体上,虽然不同的评分系统的复杂程度和评分点数量不同,但是各种CDT评分系统显示出了基本相近的灵敏度和特异度。结论增加CDT评分系统的细节和复杂性不会增加CDT在筛查MCI时的敏感度和特异度,因此建议在临床认知功能障碍筛查中使用简单的评分系统,如CERAD评分系统等。Objective To probe the validities of different scoring systems of CDT in cognitive screening. Methods 75 patients with MCI and 80 normal patients from Suzhou municipal hospital were received CDT. The results were scored under different scoring systems to screen MCI. Results Overall, although different scoring systems differred in complexity and scoring points, however, the various CDT scoring systems showed almost similar sensitivity and specificity. Conclusion Increasing the details and complexity of the CDT scoring system does not increase the sensitivity and specifcity of CDT in screening for MCI, it is therefore recommended that a simple scoring system be used in clinical cognitive impairment screening, such as CERAD scoring system and so on.
