轻度阿尔茨海默病持续性注意功能的相关性研究

摘要

Objective To explore the condition and the related risk factors for attention function damage in patients with mild Alzheimer'S disease(AD). Methods　Continuous performance test (CPT)was performed in 100 healthy elder people and in 68 patients with mild AD before treatment and after 8 weeks'treatment.Mini-mental state examination(MMSE)and behavioral pathology in Alzheimer's disease rating scale(BEHAVE-AD)were used to assess the disease.Regression analysis was also used in this study. Resuits The omission rate,mistake rate,reaction time and coefficient of variation of most iterns(visual one objective continuous ear continuous performance test,VOT;visual successive objective objective continuous performance test,VST;ear continuous performance test,ET)of CPT inpatients with AD were abnormal,even after 8 weeks'treatment.These parameters were improved after 8 weeks'treatment although they were higher than those in control group.The parameters before treatment had correlation with the course of disease and the behavior and psychological symptoms of dementia(BPSD). Conclusions　Attention function damage in patients with AD is wide and severe,and the parameters of CPT before treatment are correlated with the course'of disease and BPSD.%目的 了解轻度阿尔茨海默病(AD)患者注意功能损害情况及其相关因素. 方法 对68例轻度AD病患者在入组时、入组治疗8周后和100例健康老年人进行了连续操作试验(CPT)测试,以简易精神状态量表(mini-mental state examination,MMSE)和AD病理行为评分表(BEHAVE-AD)评定病情,并对测试结果、病程、病情严重度、年龄等进行回归分析. 结果 AD患者的所有CPT指标视觉单目标持续性注意测验(VOT)、视觉连续目标持续性注意测验(VST)、听觉持续性注意测验(ET)的漏答率、误答率、反应时间和变异系数均高于健康对照组,人组治疗8周后略有好转,但仍比健康人高,人组时CPT结果与病程、病情严重程度有关. 结论 AD患者注意损害广泛而严重,注意损害与病程、精神行为症状有关.
