University of Rochester study finds circadian rhythm strengthening aids stroke recovery in mice

Scientists at the University of Rochester Medicine discovered that strengthening the body's natural daily rhythms improved stroke recovery in mice by enhancing the brain's waste-clearing system and reducing inflammation. The treatment showed effectiveness even when started three days after stroke, published in the Journal of Clinical Investigation.

Top claims

▪Researchers from the University of Montana noted that unequal access to stroke prevention, acute care, and rehabilitation services complicates recovery, highlighting the need for accessible therapies like birdwatching.
▪University of Rochester Medicine researchers suggest that stroke impairs glymphatic function, causing a failure in the clearance of inflammatory signaling molecules that leads to tissue damage.
▪The glymphatic system, discovered in 2012 by Maiken Nedergaard's laboratory at University of Rochester Medicine, moves cerebrospinal fluid through the brain to clear waste products and debris.
