"The study demonstrates that exercise-conditioned plasma transfers cognitive benefits, but the identity of the active circulating factors remains unknown. Understanding these factors is critical for developing targeted therapeutic interventions for POCD without requiring exercise.

Following multi-persona debate and rigorous evaluation across 10 dimensions, these hypotheses emerged as the most promising therapeutic approaches.
Direct pharmacological agonism of M1 muscarinic acetylcholine receptors (CHRM1) can substitute for exercise by activating the medial septum-hippocampal cholinergic circuit, enhancing PV interneuron function and gamma oscillations, without requiring circulating plasma factors.
Exercise-conditioned plasma contains factors that suppress microglial C1q expression and complement cascade amplification, preserving PV-positive interneuron function and gamma oscillations. This directly extends the established SASP-complement model to explain exercise neuroprotection.
