Outline of Final Research Achievements	The purpose of this study was to explore the differences in emotions between people with mild cognitive impairment (MCI) and Alzheimer's disease (AD) during group rehabilitation using facial expression analysis. Thirty patients who participated in a group rehabilitation at our center were included in the study. During each task, the subject's face was photographed from the front with a small camera, and the emotional values (anger, contempt, disgust, fear, joy, sadness, and surprise) were estimated by artificial intelligence. Dual tasks and production activities, which require cognitive thinking simultaneously with physical activity, were more challenging for AD patients, while tasks that used diverse cognitive functions, such as production activities, elicited pleasure in MCI patients. In addition, feelings of anxiety about falling were higher in AD during the double task training.

Academic Significance and Societal Importance of the Research Achievements	本研究から、軽度認知障害やアルツハイマー型認知症患者のリハビリテーションにおいて、表情の観点からそれぞれの疾患に快・不快刺激となる課題について明らかとなった。これは、認知機能が低下した患者が認知症予防や認知機能維持のために継続的なプログラムに参加することに繋がると考えられる。また、認知機能が低下した患者の重症度に応じたプログラム難易度付けが可能で、患者にとって難易度が高すぎるプログラムを避けることで、行動・心理症状の出現や拒否を防ぐことも可能である。また、専門家のいない地域のデイサービスなどでも、レベルに応じたプログラムが実施可能であり、病院以外でのリハビリテーション実施場所の拡大に繋がる。
