Sports-related concussion affects an estimated 3.8 million Americans annually, with many more undiagnosed due to failure to recognize or report symptoms. Current management has moved beyond the outdated approach toward evidence-based assessment, graded return-to-play protocols, and individualized recovery management. Healthcare facilities treating athletes benefit from diagnostic equipment supporting concussion assessment.
Recognition: The Most Critical Step
Concussion symptoms span physical, cognitive, emotional, and sleep domains. Physical: headache (87% of concussions), dizziness, nausea/vomiting, visual disturbances, light and noise sensitivity. Cognitive: "foggy" feeling, difficulty concentrating, slowed processing. The SCAT5 standardizes sideline assessment with symptom checklist, cognitive assessment, neurological screening, and balance evaluation. Any athlete with suspected concussion should be immediately removed from play — the "when in doubt, sit it out" principle is absolute.
Graduated Return-to-Play Protocol
GRTP protocols consist of 6 stepwise stages: (1) Symptom-limited activity; (2) Light aerobic exercise below symptom threshold; (3) Sport-specific exercise; (4) Non-contact training; (5) Full-contact practice after medical clearance; (6) Return to competition. Each stage requires 24 hours minimum; any return of symptoms mandates regression and rest. The "Buffalo Protocol" of early sub-threshold aerobic exercise initiated within 24–48 hours reduces symptom duration — a 2019 JAMA Pediatrics RCT found athletes randomized to early aerobic exercise were 3× more likely to recover within 2 weeks versus strict rest.
