Appendix A: Summary of evidence-based guideline for clinicians, Update: Evaluation and management of concussion in sports.

A 19-year-old female with no significant past medical history is referred to the neurology clinic by her athletic department for management of a recent concussion. The patient plays collegiate soccer. Three days previously, she had been playing in a highly contested match with her college’s main rival. While going to “head the ball,” she collided with another player and struck her head. She immediately fell to the ground. There was a brief loss of consciousness. Afterward, she was conversant but dazed. The team’s athletic trainer promptly used the Standard Assessment of Concussion (SAC) to collect acute clinical data and removed her from play because of a suspected concussion. Due to concerns for an emergent injury, she was taken to the emergency room, where an appropriate trauma evaluation was performed, including a head CT, and was unremarkable. She was then diagnosed with a concussion and discharged home.
