Outline of Research at the Start

脳内リンパ系の活動性は、覚醒時と比較して睡眠時に大幅な効率の増大を示す事が示されている。本研究では、ヒトを対象として、睡眠に関連した脳内リンパ系の動態を、新たな手法を用いて非侵襲~無侵襲的に評価することを目的とする。研究に用いる主な手法はDiffusion Tensor Image analysis Along the Perivascular Space (DTI-ALPS)法である。この手法は、放線冠部分では、血管周囲腔の走行方向と投射繊維、連合線維の走行方向が互いに直交する事を利用して、拡散テンソル法で得られた3次元拡散データから、血管周囲腔の方向の拡散成分の比を算出する方法である。

Outline of Final Research Achievements

An imaging assessment of cerebral interstitial fluid dynamics related to sleep revealed significant correlations with the ALPS-index. The analysis showed an inverse correlation between the index and latency to persistent sleep, and positive correlations with total sleep time and sleep efficiency. Multiple regression analysis demonstrated that poor sleep parameters, excluding latency to sleep onset, led to a decrease in the ALPS-index. A linear mixed model suggested that initial sleep conditions might influence the ALPS-index later. Additionally, Ktrans measurements showed a significant correlation with latency to sleep onset, and choroid plexus volume negatively correlated with total sleep time, indicating that worse sleep conditions are associated with major changes in the ALPS-index. These findings emphasize the impact of sleep quality on brain fluid dynamics and the importance of managing sleep disorders.

Academic Significance and Societal Importance of the Research Achievements

Glymphaticシステムは、脳内の老廃物を排出する重要な機序であり、血管周囲腔を中心に脳脊髄液や脳間質液が流れることで機能する。このシステムは特に睡眠中に排泄効率が向上する。本研究ではその非侵襲的な評価の方法として、拡散画像を用いたdiffusion tensor image analysis along the perivascular space(DTI-ALPS)などでの評価を行った。これらの手法を活用することにより、睡眠とGlymphaticシステムの関係を明らかにし、睡眠の質の低下が認知機能に与える影響の評価や予防、改善策の開発が期待されている。
