Outline of Final Research Achievements

We observed that several metabolomics were associated with change in congnitive function. After excluding metabolomics which highly correlated with other metabolomics, we selected 6 metabolme markers to establish metabolome score. Using the score, higher metabolome score showed lower decline of cognitive function. Especially, participnts with metabolome score 0 showed marked decline in cognitive function
The prediction model with metabome score showed larger area under the ROC curve(0.772) compared with the model without. Prediction model with metabolome score may have better potential to predict cognitive dysfucnction. Validation study using ToMMo is now analyzing.

Academic Significance and Societal Importance of the Research Achievements

血液中の代謝物質を用いることで認知機能低下を予測できる可能性が示された。現段階では1つのコホートデータだけでのモデル構築であり、再現性の確認が必要である。またそれぞれのメタボロームがマーカーなのか原因物質かは不明であり、その検証が必要ではあるが介入の対象となる可能性もあり、今後の検討が必要になる。
モデルの構築が進めば認知機能低下ハイリスク者の同定が可能となり、認知機能低下予防事業にも貢献すると考えている。
