识别面部情绪是人际交流的一个重要方面，可能会在阿尔茨海默病（AD）中受损。作者研究了AD患者、健康老年志愿者和老年非痴呆精神科门诊患者的面部情绪匹配、面部情绪标记和同异情绪区分。与两个对照组相比，AD患者在所有三项指标上均显著受损。AD患者在面部身份匹配任务中的情绪也受损.使用面部身份匹配分数作为协变量提供的证据表明，面部情绪处理缺陷可能是独立的损伤，在非情绪的面孔处理。AD患者在标记悲伤的面部表情时也有选择性损伤。作者得出结论，AD患者在识别面部情绪方面存在缺陷，这可能与他们在识别面部非情绪特征方面的障碍无关。
Recognizing facial emotions is aft important aspect of interpersonal communication that may be impaired in Alzheimer's disease (AD). The authors examined facial emotion matching, facial emotion labeling, and same-different emotion differentiation in AD patients, healthy elderly volunteers, and elderly, nondemented psychiatric outpatients. Compared with both control groups, AD patients were significantly impaired on all three measures. AD patients were also impaired emotion a facial identity matching task. Using facial identity matching scores as a covariate provided evidence suggesting the facial emotion processing deficit may be independent of impairment in nonemotional face processing. AD patients also had selective impairment in labeling facial expressions of sadness. The authors conclude that patients with AD have deficits in recognizing facial emotions, which may be independent of their impairment in recognizing nonemotional features of faces.
