摘要
目的通过比较遗忘型轻度认知障碍(amnestic mild cognitive impairment,aMCI)和血管性认知障碍非痴呆型(vascular cognitive impairment-no dementia,VCI-ND)患者及正常老年人群在简易智能精神状态检查量表(mini mental state examination,MMSE)、听觉词语学习测验(auditory verbal learning test,AVLT)、画钟试验(clock drawing test,CDT)及临床痴呆评定量表(clinical dementia rating scales,CDR)中的表现,进一步分析aMCI和VCI-ND在认知损害方面的不同特点。方法选取首都医科大学宣武医院神经内科门诊收治aMCI患者23例及VCI-ND患者27例(CDR=0.5分),同时选取40名正常老年人(CDR=0分)作为对照组。每位受试者均进行MMSE、AVLT、CDT及CDR等神经心理学量表测查,分析以上3组被试各项神经心理学测查得分之间的差异。结果各组受试者的年龄、性别及受教育程度差异无统计学意义(P>0.05),具有可比性。aMCI和VCI-ND组在MMSE、CDT、即刻记忆、延迟记忆及延迟再认检测中的平均值均低于对照组,且差异均具有统计学意义(P<0.05)。aMCI和VCI-ND两组除延迟再认检测外,其余各项测查的平均分均无统计学意义(P>0.05)。在延迟再认检测中,aMCI组(6.65±4.00)较VCI-ND组(8.67±2.76)再认词语数量少,两组延迟再认的得分均低于对照组(12.83±1.77),差异有统计学意义(P<0.05)。结论 aMCI和VCI-ND在记忆力、执行能力和信息处理能力方面较正常老年人均有所损害。由于aMCI和VCI-ND不同的病理改变,导致患者存在不同类型的记忆储存和提取机制。
