Outline of Final Research Achievements

To elucidate the cognitive mechanisms that cause functional disability in patients with mild cognitive impairment (MCI) and early-onset Alzheimer’s disease (eAD), we analyzed behavioral, neurobiological, and neuropsychological data using the number of fixation and action errors during instrumental activities of daily living tasks; brain imaging data by voxel-based morphometry, diffusion tensor imaging, and so on; and the scores of neuropsychological test such as memory, executive function, and so on. The analysis of action errors revealed that a subtle decline in functional ability was observed not only in eADs but also in MCIs. A very short fixation of MCIs, which was considered an indicator of action planning, was significantly higher in the experimental group compared to controls. Action planning increased during the early phase of functional disability correspond to a compensatory operation for the implicit disorder of automated action.

Academic Significance and Societal Importance of the Research Achievements

認知症者とその介護者のQOLに最も影響する問題の1つは生活機能の自立である.しかし科学的妥当性を持った早期介入方法は未だ確立されていない.軽度認知障害者や早期アルツハイマー病患者の生活機能障害の認知メカニズムの解明により,早期介入方法確立に向けた貢献が期待できる.高次認知機能である遂行機能の下位機能である運動計画等がIADL遂行過程に与える影響について検討した.簡易なIADLであっても軽度認知障害者は運動計画を反映する眼球運動指標が高いことから,学習し自動化された運動であっても,より意識的努力によって遂行していることが考えられた.遂行機能の別の下位機能の検討が今後さらに必要である.
