Outline of Final Research Achievements

In order to expand the application of skin blotting, which has originally been developed as an skin assessment technique, to a whole-body assessment such as blood tests, we attempted to apply it for the examination of mild cognitive impairment (MCI) in this study. In a cross-sectional study subjected older population, we analyzed the accuracy of the Amyloid b/Albumin ratio measured by skin blotting in determining MCI, identified by the Japanese version of the Montreal Cognitive Assessment (MoCA-J). The sensitivity and specificity of the Amyloid b/Albumin ratio were 0.889 and 0.889, respectively. These results indicate that skin blotting is an effective biochemical test for MCI identification as an alternative to blood tests.

Academic Significance and Societal Importance of the Research Achievements

超高齢化社会において認知症予防が社会的な要請となるなか、MCIのスクリーニングに基づく早期介入の重要性が認識されている。血液検査によるMCI同定法が開発され普及が図られているが、スキンブロッティングによる非侵襲的MCI検査が実現することにより、継続的なセルフモニタリングを実現することができる。また、Amyloid βは血液検査などでも広く用いられているMCIマーカーであるが、Albumin比は新たな指標として学術的意義も高い。
