中文摘要：

阿尔茨海默病（AD）与血管性痴呆（VD）为两类独立的脑实质性疾病,但两者在临床工作中往往难以区分,且国际上尚未有统一标准鉴别这两种疾病。AD患者记忆力以及语言表达能力弱于VD患者,而VD患者的注意力受损程度重于AD患者。此外,AD与VD患者尚存在着血糖、血脂等血管因素,MRI以及脑电波方面的差异。本篇将着重探讨两种疾病的鉴别要点以及其在临床上的应用价值。

英文摘要：

Alzheimer＇s disease （AD） and vascular dementia （~D） are two types of independent substantial brain disease, often difficult to differentiate in clinical work, and there is no unified standard in the world to identify these two diseases. Patients with AD have weaker memory and language expression ability than VD patients, but attention degree of damage is more serious in VD than in AD, and with more differences for values of blood sugar, blood lipids and blood vessels, MRI, and the brain waves between AD and VD. This paper will focus on the identification of two kinds of diseases and its clinical application value.
