Outline of Final Research Achievements

This study was conducted to ascertain whether a Natural Language Processing (NLP) based system can detect dementia or not. We obtained materials of two types from dementia patients: (1) speech samples, and (2) cognitive function level test scores from Hasegawa’s Dementia Scale; Revised (HDS-R), a test used in Japan for dementia patients.
Then, we investigated that the language based index is related to the level of dementia.

Academic Significance and Societal Importance of the Research Achievements

現時点で対象としているアルツハイマー型認知症のみならず,本研究により得られる知見や成果は,言語と関係した他の疾患についても有効である可能性が高い.本研究によって測定法が確立されることで,これら他の障害や疾患への応用も可能となり,大きな波及効果が期待される.
加えて,本研究の方法論である<患者の語りを引き出す>という行為そのものが,社会を変える可能性がある.本来口を閉ざしがちである認知症やASD者の語りを引き出し,その土台となる場を生み出すことによって,これらの疾患への社会的理解を促進し,結果的に疾患への社会的無理解からくる偏見や診断への抵抗感を大きく軽減できる可能性がある.
