Recent research has brought into question the conventional wisdom that more rest is better for concussion recovery in pediatric patients. One study found that patients prescribed only 24-48 hours of rest recovered just as well or better than those prescribed 5 days of rest. Additionally, "Heads Up", a CDC initiative, aims to increase concussion awareness and prevention through educating athletes, parents, and coaches. Finally, all 50 states now have laws regarding concussions in youth sports that primarily focus on education, removal from play, and medical clearance to return to play. A study of Rhode Island's law found it doubled emergency room visits for concussions without increasing medical imaging, suggesting greater awareness of pediatric concussions.
