The developing brain, specifically in adolescents, is sensitive to the effects of sport-related concussion—even more so than adults or children.15
The time required to return to normal function (determined through brain and symptom testing) is fastest in adults and professional athletes (3-5 days)16, followed by college athletes (5-7 days)17 and high school athletes (10-14 days)18. Clinical evidence suggests that youths aged 10-14 took as long as high school athletes to heal, if not longer.
Dr Michael Clarfield answers the question:
Women are more susceptible to concussion than men and can take longer to recover. This may be due to having less neck muscle strength than men, making women more vulnerable to whiplash motion on the brain.19
