severity of the injury, duration of signs and symptoms, time between injuries, and availability of experienced personnel to conduct repeated assessments and monitor recovery. It is important to combine tests of cognitive function, postural stability, and symptomatology to determine the athlete's status.

4. The injury should be graded or classified only after the athlete has been rendered asymptomatic, whether it is 5 minutes, 5 hours, 5 days, or 5 weeks following the injury. Your goal should always be to try to prevent a recurrent injury, and research suggests that all the aforementioned factors can influence the outcome.

5. Athletic trainers, team physicians, neurosurgeons, and neuropsychologists should work together as a team to determine the athlete's readiness to return safely to competition following a head injury.
