Rochester Study: Circadian Rhythms Aid Stroke Recovery

A new study by scientists at the University of Rochester Medical Center, led by neuroscientist Lauren Hablitz and building on the foundational work of Maiken Nedergaard, suggests that reinforcing the body's natural daily rhythms can significantly improve brain recovery after a stroke. Published in the Journal of Clinical Investigation, the research found that interventions like timed light exposure, Melatonin, the drug KL001, and time-restricted feeding improved recovery in mouse models of stroke. These benefits were linked to improvements in the glymphatic system, the brain's waste-clearing network, and reductions in inflammatory molecules. The study highlights that stroke is not just a vascular event but also a 'disorder of timing,' and that restoring circadian rhythms could offer a new strategy for stroke rehabilitation, potentially even at home.
