Outline of Research at the Start

臨床症状のない認知症プレクリニカル期の重要性が認識されているが、患者特定には、バイオマーカーが高額・侵襲性を伴う、簡易スクリーニングの臨床検査は十分な精度がない、という課題がある。
近年、AI技術を用いた音声や歩行などの行動特徴の定量化を利用する事で、高い精度での認知症スクリーニングが可能であること、及び臨床検査と組み合わせることでその精度が更に向上することが示されている。
本研究では、この研究をプレクリニカル期に拡張し、バイオマーカーによるプレクリニカル期進行度と相関する行動特徴を同定し、日常生活及び臨床現場の双方で利用可能な非侵襲で簡便なスクリーニング手法として新規に定式化する事を目指す。

Outline of Final Research Achievements

The purpose of this study was to identify the behavioral features that correlate with various biomarkers and neuropsychological tests, and to develop a non-invasive and low-cost early screening method for dementia that can be used in both daily life and clinical settings. We constructed a screening model by using AI technology to extract and combine the features from behavioral data, including gait, speech and drawing, obtained from activities of daily living. The results showed that the cases with mild cognitive impairment and those with Alzheimer’s disease could be discriminated from healthy controls with a high accuracy of more than 90%.

Academic Significance and Societal Importance of the Research Achievements

本研究で得た、歩行、音声、描画などの行動特徴を用いたスクリーニング手法は、非侵襲的で安価な手段として、医療機関におけるAD及びMCIの早期発見に役立つだけでなく、多数例のスクリーニングが必要な疾患修飾薬等の新薬の治験の際にも力を発揮すると思われる。さらに、本手法は、地域の健康診断や介護予防教室などの専門家がいない環境においても、認知症の早期スクリーニングのツールとして利用できる可能性があり、今後の発展が期待できる。
