New data from animal models explains why.   Georgetown University Medical Center neuroscientists say rest allows the brain to reset neural networks and repair any short-term injury. The new study in mice also shows that repeated mild concussions with only a day to recover between injuries leads to mounting damage and brain inflammation that remains evident a year after injury. “It is good news that the brain can recover from a hit if given enough time to rest and recover.
