Outline of Final Research Achievements

The present study has the following findings: 1) Time compression in PD internal clock may be entrained even after learning accurate time duration. This may be associated with disrupted cognition in PD; 2) these is impaired cross-modal function for vision/olfaction due to posterior putamen deficit. Cross-modal dysfunction may serve as the basis of a novel precursor for PD; 3) AD patients alternate past and present without complete awareness and cannot imagine a future other than one ending in death; 4) Correct age awareness is essential for realistic recognition of the remote past in relation to the present.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は多岐に渡る神経疾患の障害を横断的に検討することによって「こころの時間」を生成・表出・保持するメカニズムが脳部位ごとに分かれており、またそれぞれの機能によって中心的な役割を担う脳部位があることを示した点である。一方社会的意義としては、これらの研究成果は疾患の診断に有用である点、また治療法の選択肢が増えることで、患者の希望に合わせたより柔軟な治療方針を作成するのに役立つと考えられる。
