行为变异型额颞叶痴呆(FTD)患者在识别面部情绪方面存在困难，这一缺陷可能导致他们的社交技能受损。在三个实验中，我们通过比较6名社会行为受损患者、9名阿尔茨海默氏症患者和10名年龄匹配的健康成年人，调查了FTD在面部情绪识别方面的缺陷。实验一显示，FTD患者对负面面部情绪的识别能力受损。当参与者必须确定两张脸表达的是相同还是不同的情绪时，实验2重复了这些发现。实验3是一项对照研究，参与者必须辨别两张脸是否为同性。在这项非情绪处理任务中，两组患者的表现都比正常参与者差，但FTD患者的表现与阿尔茨海默病患者一样好。我们的结论是，FTD患者在对负面面部情绪的识别方面存在损害。(C)2005爱思唯尔有限公司。保留所有权利。
Patients with behavioral variant of frontotemporal dementia (FTD) have difficulties recognizing facial emotions, a deficit that may contribute to their impaired social skills. In three experiments, we investigated the FTD deficit in recognition of facial emotions, by comparing six patients with impaired social conduct, nine Alzheimer's patients, and 10 age-matched healthy adults. Experiment I revealed that FTD patients were impaired in the recognition of negative facial emotions. Experiment 2 replicated these findings when participants had to determine whether two faces were expressing the same or different emotions. Experiment 3 was a control study in which participants had to discriminate whether two faces were of the same sex. In this non-emotional processing task, both patient groups performed worse than normal participants, but FTD patients performed as well as Alzheimer's patients. We conclude that FTD patients are impaired in the recognition of negative facial emotions. (c) 2005 Elsevier Ltd. All rights reserved.
