Experts urge caution in concussion management for athletes.

Athletes who suffer from mild concussion should avoid total rest and resume light physical and mental activities to aid their recovery, according to a consensus statement issued by more than 100 international researchers and clinicians. The statement contradicts recent UK guidance to avoid contact sport for 21 days after sustaining a concussion and avoid any form of training for 14 days. The Concussion in Sport Group (CISG) hosts a conference every four years and subsequently issues a consensus statement aimed at optimising the care of athletes who have or are at risk of brain injury.
