文摘目的研究轻度认知损害（mild cognitive impairment，MCI）患者空间结构能力的缺损与保持状况。方法将被试者分为3组：健康对照组122名，其中男51名、女71名；MCI组205例，男95例、女110例，其中遗忘型MCI（aMCI）133例，非遗忘型MCI（naMCI）72例；阿尔茨海默病（AD）组75例，男36例、女39例。全部进行Rey—Osterrieth复杂图形测验（CFT）、画钟测验（CDT）、搭火柴测验3个结构能力测验，同时完成简易精神状态量表（MMSE）等测验。健康对照组、MCI组和AD组MMSE平均得分分别为28．24±1．74、27．39±1．83和19．98±3．23。采用SPSS for windows11．5统计软件，计数资料采用卡方检验，3组间比较采用One—way方差分析，然后采用Bonferroni（LSD）法进行多重比较。结果（1）以健康组为对照，CFT模仿得分和CDT总分与年龄、教育年限没有显著相关性，搭火柴测验-旋转部分（STR）与年龄有相关性（r=-0．179，P〈0．05），与教育年限没有显著相关性。（2）CFT模仿得分与CDT总分（r=0．337）、STR（r=0．232），CDT总分与STR（r=0．235），均有显著相关性（均P〈0．01）。（3）CFT模仿和CDT总分分别与反映执行功能的连线测验B、Stroop色词测验卡片C耗时数的相关性最高，而STR与反映记忆的指标听觉词语学习测验的相关性高。CFT模仿、CDT总分和STR在健康对照组、MCI组和AD组之间差异有统计学意义。（4）在识别MCI方面，经过对3组结构测验表现的比较得出STR优于CFT模仿、CDT总分。结论结构能力损害是MCI的表现之一，空间旋转能力的评估在识别MCI方面优于CFT模仿、CDT总分。
