Cognitive and functional recovery after a stroke or traumatic injury requires intense rehabilitative therapy to help the brain repair and restructure itself. New findings by researchers at University of California, San Diego School of Medicine report that not only is rehabilitation vital – in an animal model, rats with cortical injury that did not receive intensive rehab did not rebuild brain structure or recover function – but that a longer, even more intense period of rehabilitation may produce even greater benefit.
