To provide a review of the literature on the perception of emotion in Alzheimer's dementia (AD) and Mild cognitive impairment (MCI), and to evaluate if emotion intensity matters.
A systematic literature search of PubMed database was carried out using combinations or truncated versions of the keywords "MCI", "Alzheimer", "emotion recognition", "facial emotion recognition", "social cognition" or "emotion perception". Twenty-eight articles were found to meet the inclusion criteria.
Overall, AD patients performed worse on emotion perception than MCI patients and healthy controls. Half of the studies found an emotion-specific deficit for MCI patients on the emotions anger, sadness and fear. However, studies taking emotion intensity into account are still scarce.
An emotion-intensity based approach may be more sensitive to detect subtle impairments in facial emotion recognition. Future studies need to take emotion intensity into account and also consider confounding factors such as overall cognition and mood.
对有关阿尔茨海默病（AD）和轻度认知障碍（MCI）中情绪感知的文献进行综述，并评估情绪强度是否重要。
使用关键词“MCI”、“阿尔茨海默病”、“情绪识别”、“面部情绪识别”、“社会认知”或“情绪感知”的组合或截断版本，对PubMed数据库进行系统的文献检索。发现28篇文章符合纳入标准。
总体而言，AD患者在情绪感知方面的表现比MCI患者和健康对照更差。一半的研究发现MCI患者在愤怒、悲伤和恐惧情绪方面存在特定情绪缺陷。然而，考虑情绪强度的研究仍然很少。
基于情绪强度的方法可能对检测面部情绪识别中的细微损伤更敏感。未来的研究需要考虑情绪强度，同时也需要考虑诸如整体认知和情绪等混杂因素。
