采用命名和理解任务对13例短暂性急性精神错乱（ACS）患者和11例可能患有阿尔茨海默病（AD）的患者进行了调查，他们的年龄和迷你精神状态评分具有可比性。后者既包括之前在命名任务中包含的单词，也包括不熟悉的项目。每组5例，1 ~ 3天后重复评估。两组的误命名数量相当。词频对命名成功的影响仅在AD组中被发现。在ACS组中，不相关的误命名明显更频繁。进一步分析表明，ACS患者中部分不相关的错误命名是由视觉错觉引起的。针对目标的行为策略在Ad患者中更为常见。持续性，尤其是侵入型，是ACS患者的特征，仅在AD患者中偶尔发现。随着时间的推移，AD组的命名失败有一个项目一致性，但ACS组没有。ACS组的跨模态表现一致性似乎高于AD组。
Thirteen patients suffering from transient acute confusional states (ACS) and 11 patients with probable Alzheimer's disease (AD) who were comparable for age and Mini-Mental State score were investigated with a naming and a comprehension task. The latter included both words that were previously included in the naming task and unfamiliar items. With five patients of each group, the assessment was repeated 1 to 3 days later. The number of misnamings was comparable for both groups. An effect of word frequency upon naming success was found only with the AD group. Unrelated misnamings were significantly more frequent in the ACS group. Closer analysis suggested that part of the unrelated misnamings in the ACS patients were caused by visual misperceptions. Behavioral strategies aiming at the target were more frequently exhibited by Ad patients. Perseverations, especially of the intrusion type, were characteristic for ACS patients and only occasionally found with AD. There was an item consistency over time with naming failure in the AD, but not in the ACS group. Cross-modal performance consistency seemed greater in the ACS than in the AD group.
