TL;DR: Data are insufficient to show that any intervention enhances recovery or diminishes long-term sequelae postconcussion, and practice recommendations are presented for preparation counseling, management of suspected concussion, and management of diagnosed concussion.

TL;DR: The presence of amnesia, not loss of consciousness, appears predictive of symptom and neurocognitive deficits following concussion in athletes, and athletes presenting with on-field amnesia should undergo comprehensive and individualized assessment.

TL;DR: The failure of this study to find any relationship between LOC and neuropsychological functioning in a large sample of patients with mild head trauma calls into question the assignment of primary importance to LOC in grading severity of concussion.

TL;DR: Critically examines concussion management guidelines and makes recommendations for the development of practical strategies and two actual concussion cases illustrate these issues.

TL;DR: When evaluating concussion, symptoms of headache >3 hours, difficulty concentrating >3hours, retrograde amnesia, or loss of consciousness may indicate a more severe injury or prolonged recovery; great caution should be exercised before returning these athletes to play.
