【摘要】 目的:分析阿尔茨海默病(AD)和脑淀粉样血管病(CAA)的临床关联性和影像学关联性。方法:选取2016年1月-2017年7月本院收治的15例AD患者(A组)、20例CAA患者(B组)、9例AD合并CAA患者(C组)。评价三组认知障碍进展程度,观察三组MRI影像学表现。结果:第1、2次评估时,A、B组患者MMSE评分、CDR评分、ADL评分、ADAS-Cog评分、MOCA评分比较,差异均无统计学意义(P>0.05);C组上述指标与A、B组比较,差异均有统计学意义(P<0.05)。MRI表现上,A组颞叶萎缩较明显,B组皮质萎缩较明显,C组全脑萎缩较明显。结论:AD、CAA的临床表现均以认知障碍为主,两者的合并发生会导致患者病情发展速度加快,两者互为疾病发展的促进因素。

Clinical and Imaging Correlation of Alzheimers Disease and Cerebral Amyloidosis/LIAN Yongjun,ZOU Liangyu.//Medical Innovation of China,2018,15(16):0-020
【Abstract】 Objective:To analyze the clinical relevance and imaging correlation of Alzheimers disease(AD) and amyloid angiopathy (CAA).Method:A total of 15 AD patients(A group),20 CAA patients(B group) and 9 AD patients complicated with CAA(C group) were admitted to our hospital from January 2016 to July 2017 were selected.They were evaluated on the progress of cognitive impairment,and the MRI imaging findings of three groups were observed.Result:In the first,second assessment,the MMSE score,CDR score,ADL score,ADAS-Cog score and MOCA score of A and B group were compared,the differences were not statistically significant(P>0.05),the above indexes in C group were compared with those of A and B group,the differences were statistically significant(P<0.05).On the MRI performance,the atrophy of temporal lobe was more obvious in A group,the atrophy of cortex was more obvious in B group,and the whole brain atrophy was more obvious in C group.Conclusion:The clinical manifestations of AD and CAA have been mainly cognizant disorders,the combination of them can accelerate the development of patients condition,and they are mutually promoting factors of disease development.

阿尔茨海默病(AD)和脑淀粉样血管病(CAA)在病理改变及临床表现有较多相似之处,也存在明显差异[1-2]。本研究对AD和CAA的临床关联性和影像学关联性进行分析,旨在进一步明确两种疾病的发病机制,为医疗领域探索AD、CAA以及AD合并CAA新的治疗靶点提供参考价值。现报道如下。
1 资料与方法
1.1 一般资料 选取2016年1月-2017年7月本院收治的15例AD患者(A组)、20例CAA患者(B组)、9例AD合并CAA患者(C组)为研究对象。纳入标准:明确诊断为AD或CAA。排除标准:合并严重器质性疾病的患者。本研究在获取患者直系亲属知情、同意后开展,且已经院伦理委员会审核批准。
1.2 方法
1.2.1 临床关联性分析 应用简易精神状态评价量表(MMSE)、临床痴呆评定量表(CDR)、日常生活能力量表(ADL)、AD评价量表-认知分表(ADAS-Cog)、摩卡量表(MOCA)评估三组患者认知障碍进展程度,半年1次,均评估2次。(1)MMSE评分标准:评价维度包括定向力、记忆力、注意力和计算力、回忆能力、语言能力,最高得分30分,得分>26分为正常,21~26分为轻度认知障碍,10~20分为中度认知障碍,<10分为重度认知障碍[3]。(2)CDR评分……
