摘要
目的了解轻度认知功能障碍 (MCI)和轻度阿尔茨海默病 (AD)患者的持续注意功能。方法采用持续作业任务(CPT) ,对 10例轻度AD患者、10例MCI患者和 10例正常老年人进行对照研究。结果轻度AD患者的反应时显著长于对照组 (P<0 0 0 1) ,漏报率高于对照组 (P <0 0 5 ) ,虚报率与对照组无显著性差异 (P =0 0 64 ) ,漏报率随时间延长增高。MCI组各指标与对照组无显著性差异。结论轻度AD患者存在持续注意功能障碍 ,MCI患者持续注意功能正常。
ObjectiveTo deter mine the sustained attention function of the patients with mild Alzheimer's disease(AD) and mild cognitive impairment(MCI).Methods10 patients with MCI, 10 with mild AD and other 10 healthy elderly controls were tested with Continuous Performance Task(CPT) aimed to assess sustained attention. ResultsCompared with the normal controls, the mild AD patients reacted very more slowly( P <0.001), missed more targets( P <0.05), while that the MCI patients did was as well as the control group. ConclusionThe mild AD patients shows impairment in sustained attention function, but the MCI patients shows a preserved ability of sustained attention function.
