Previous concussion – According to prospective studies involving thousands of athletes, a history of concussion substantially increases the risk of recurrence and prolonged recovery from subsequent injury.
Patients with unresolved symptoms from a prior injury appear to be at greatest risk; recurrent injury is most likely to occur within the first 10 days after the initial injury.
