神经心理测验和评价量表在阿尔茨海默病临床试验中的应用

2014-03-13 赵建中 审评四部审评八室

    阿尔茨海默病为慢性进行性神经变性疾病,以认知功能损害、日常生活能力进行性下降及神经心理症状和精神行为异常为主要特征。阿尔茨海默病同很多其它精神类 疾病一样,没有非常特异的生物学标志,临床诊断主要依据病史、体检、实验室检查和辅助检查结果进行综合分析得出,确诊则有赖于脑神经病理检查。在临床诊断 标准中,需要心理测验和量表检查帮助诊断,病情严重程度的判断

阿尔茨海默病为慢性进行性神经变性疾病,以认知功能损害、日常生活能力进行性下降及神经心理症状和精神行为异常为主要特征。阿尔茨海默病同很多其它精神类 疾病一样,没有非常特异的生物学标志,临床诊断主要依据病史、体检、实验室检查和辅助检查结果进行综合分析得出,确诊则有赖于脑神经病理检查。在临床诊断 标准中,需要心理测验和量表检查帮助诊断,病情严重程度的判断,治疗效果的判断也主要依赖一系列的量表,特别在相关治疗药物的临床试验中,量表的选择就显 得尤为重要,可能直接关系到试验结果的科学性、可靠性,以致试验的成败。本文旨在对有关药物临床试验中所使用的量表作一个初步简单的讨论,以抛砖引玉,引 起大家对此问题的关注。     目前国内外批准用于阿尔茨海默病治疗的药物主要有他克林、多萘哌齐、利凡斯的明、加兰他敏、石杉碱甲等胆碱酯酶抑制剂,还有许多新药和新的治疗方法处于探 索阶段,正在进行临床试验。这些药物临床试验中所使用的量表可以分为两类,一类为用于疾病筛查、诊断和鉴别诊断;另一类用于疗效判断。后者又分为认知、总 体、日常生活能力、精神行为等几个方面。
