The microbiome-gut-brain axis: a new perspective on the pathogenesis and intervention of frailty.

Microbiome changes linked to aging-related weakness suggest a potential pathway for future interventions targeting frailty.

This review presents the gut microbiome-gut-brain axis as a mechanistic framework for understanding frailty in aging, highlighting how dysbiosis promotes systemic inflammation, sarcopenia, and cognitive decline. The review is most useful as a theoretical synthesis connecting microbiome interventions to frailty endpoints, though clinical evidence for microbiome-based anti-frailty interventions remains early-stage.
