AimThis study aimed to explore differences in the emotions of patients with mild cognitive impairment (MCI) and Alzheimer’s dementia (AD) in group rehabilitation using facial analysis.MethodWe conducted rehabilitation consisting of aerobic exercise, cognitive training, dual tasks (a combination of exercise and cognitive training), and creative activities in a group format with patients with MCI and dementia. The faces of the 30 patients (MCI: n=14; mild/moderate AD: n=16) who participated were filmed from the front with a small camera during the four tasks. Then, we used the Kokoro Sensor (CAC Corporation, Japan), a device which estimates emotion scores (anger, contempt, disgust, fear, joy, sadness, surprise) based on different parts of the face using artificial intelligence, to calculate emotion scores for each activity, and compared them between the MCI and AD groups.ResultsEmotion scores for fear and surprise were significantly higher for the AD group than for the MCI group during dual tasks (p=0.016), while emotion scores for joy were significantly higher for the MCI group than for the AD group during creative activities (p=0.012).ConclusionCreative activities and dual tasks, which require simultaneous physical activity and cognitive thinking, were difficult for patients with AD. On the other hand, tasks which used a range of cognitive functions, such as creative activities, evoked joy in patients with MCI. It may be beneficial to provide tasks and support to patients with respect to their unique emotions based on these results.目的：本研究旨在通过面部分析，探究轻度认知障碍（Mild Cognitive Impairment, MCI）患者与阿尔茨海默病（Alzheimer’s Dementia, AD）患者在团体康复过程中的情绪差异。 方法：我们针对MCI患者与痴呆患者开展团体形式的康复干预，干预内容涵盖有氧运动、认知训练、双任务（运动与认知训练的结合）及创意活动。对参与研究的30例患者（MCI组：n=14；轻中度AD组：n=16），在完成四项任务期间，通过小型摄像机从正面采集其面部影像。随后，我们采用日本CAC公司研发的Kokoro Sensor设备，该设备借助人工智能基于面部不同区域估算情绪评分（包含愤怒、轻蔑、厌恶、恐惧、愉悦、悲伤、惊讶七种情绪），计算各项活动对应的情绪评分，并对比MCI组与AD组的评分差异。 结果：在双任务阶段，AD组的恐惧与惊讶情绪评分显著高于MCI组（p=0.016）；而在创意活动阶段，MCI组的愉悦情绪评分显著高于AD组（p=0.012）。 结论：需要同时开展躯体活动与认知思考的双任务与创意活动，对AD患者而言难度较高。反之，涉及多类认知功能的创意活动可诱发MCI患者的愉悦情绪。基于上述研究结果，为患者提供契合其独特情绪特征的康复任务与支持方案，或可带来临床收益。
