Outline of Final Research Achievements

Cognitive function is considered important for schizophrenics to continue living in the community. In the present study, we used a "prediction-based weight-loading task" to examine the relationship between "impairment in prediction" and cognitive and social functions among schizophrenics, and a simple method for measuring impairment in prediction. The results suggested the following: (1) Regarding the relationship between prediction and cognitive function, the smaller the hand movements (impaired prediction), the greater the decline in cognitive function after the onset of schizophrenia. (2) We confirmed that "impairment in prediction" can be assessed with a cell phone built-in sensor as well as with a conventional device, and the analysis can be automated.

Academic Significance and Societal Importance of the Research Achievements

本研究は認知・運動機能の評価方法として「予測」に着目し，統合失調症の予測の障害と認知・社会機能との関連性を検討した結果、統合失調症者の予測の障害と発症後の認知機能低下との関連性が示唆された。また、評価方法として、特別な装置を用いず、携帯内蔵のセンサとアプリで実施する方法を確立した。よって、今後はこの測定方法を用いることにより、統合失調症患者に限らず、高齢者など様々な対象者の予測の障害と認知機能について検討することが可能となる。
