先前的一项研究评估了Bender格式塔测试（BGT）区分路易体痴呆（DLB）和阿尔茨海默病（AD）的能力，结果表明总分98分是区分这两种疾病的最佳临界值，而DLB往往表现出独特的错误；即“元素变形”和“格式塔破坏”。本研究的目的是：(1)检验BGT总分98分作为截断值在比以往研究更多的DLB患者中的敏感性和特异性；(2)如果截断值98不是最优，则设置新的截断值；(3)阐明DLB患者中单元变形和格式塔破坏的频率。参与者是133名DLB患者，65名AD患者和30名认知正常的老年人。所有的参与者都进行了小精神状态检查、BGT和脑磁共振成像。因此，BGT总分的临界值为98，灵敏度较低（0.58），临界值为84是区分DLB和AD的最佳临界值。此外，133例DLB患者中有32例，65例AD患者中有1例出现单元变形或格式塔破坏。本研究提示BGT是鉴别DLB和AD的有效神经心理学测试。此外，还讨论了评估DLB患者在不同类型视觉刺激下的空间和感知困难的必要性。
A previous study that evaluated the ability of the Bender Gestalt Test (BGT) to discriminate between dementia with Lewy bodies (DLB) and Alzheimer’s disease (AD) suggested that a total score of 98 is the optimal cutoff value for discriminating between these two diseases and that DLB tends to exhibit unique errors; i.e., “element deformation” and “gestalt destruction.” The objectives of the present study were: (1) to examine the sensitivity and specificity of a total BGT score of 98 as a cutoff value in greater numbers of DLB patients than in the previous study, (2) to set a new cutoff value if a cutoff value of 98 is not optimal, and (3) to clarify the frequency of element deformation and gestalt destruction in DLB patients. The participants were 133 DLB patients, 65 AD patients, and 30 cognitively normal elderly people. All of the participants underwent the Mini-Mental State Examination, BGT, and brain magnetic resonance imaging. As a result, the total BGT score cutoff value of 98 showed low sensitivity (0.58), and a cutoff value of 84 was indicated to be the optimal cutoff value for discriminating between DLB and AD. In addition, 32 out of 133 DLB patients and one out of 65 AD patients exhibited element deformation or gestalt destruction. This study suggested that the BGT is a useful neuropsychological test for differentiating DLB from AD. In addition, the need to evaluate the spatial and perceptual difficulties of DLB patients with various types of visual stimulation is also discussed.
