Time to symptom resolution, return to school, and return to play after a sport-related concussion in children and adolescents (8-17 years of age) was examined using a retrospective cohort design. A total of 198 patients aged 8 to 17 years were included, with a mean age of 13.5 years (SD = 2.2). Patients aged 8 to 12 years were symptom-free in a median of 12.0 (range 1-60) days whereas 13- to 17-year olds were symptom-free in a median of 14.0 (range 1-300) days (P = .04). Patients aged 8 to 12 years returned to learn in a median of 4.0 (range 0-30) days compared with 2.5 (range 0-55.0) days in 13- to 17-year-olds (P = .86). Patients aged 8 to 12 years returned to play in a median of 14.0 (range 4-75) days compared with a median of 19.5 (range 5-75) days in 13- to 17-year-olds (P = .06). These results indicate that children and adolescents generally take 2 to 4 weeks to recover from a sport-related concussion.
