Predicting prolonged recovery after concussion

With mild traumatic brain injury (concussion) labeled as a “signature” war injury, and heightened awareness of possible long-term effects of multiple concussions, including chronic traumatic encephalopathy, numerous studies are underway. The natural history of sports concussion is not fully defined, but research suggests that 90% of concussed individuals recover within 1 week.1 The ability to predict who might have a prolonged recovery would have great clinical import in guiding patient therapy and expectations.
