「腸と脳のコミュニケーション」を強化することで記憶力や認知機能の老化を逆転させられる可能性 - GIGAZINE

This page reports on research by Stanford University and other institutions demonstrating that enhancing gut-brain communication can potentially reverse age-related cognitive decline in mice. The study identified that the bacterium Parabacteroides goldsteinii increases with aging and directly correlates with cognitive impairment. Researchers found that administering molecules to activate the vagus nerve restored memory function in elderly mice to levels comparable to young mice, suggesting a three-stage mechanism linking gut aging, immune responses, and memory loss.
