My shallow understanding is that myelin improves neurons' connectivity, so the decrease of it would imply degrading performance in neural activities? Also, the myelination process happens when you learn new things, so it might be interesting to analyze how the recovery period might be exploited to facilitate learning. Would love to hear brain scientists thoughts.
