The study says there needs to be a national registry to monitor the rates of sports-related concussions.
Those who play football will tell you, it's a rough game especially for younger athletes.
Wednesday the committee of sports-related concussions in youth released a report calling for action on concussions among young athletes. New research shows the actual number of concussions is under-reported nationwide.
"There is a culture of resistance when it comes to reporting concussions. because you can't see a concussion, people hide their symptoms because they don't want to let their teammates or their parents or their coaches down ...sometimes it's because athletes don't recognize symptoms as a concussion," said Dr. Neha Raukar from Brown University.
The highest rate of concussions was found in football. Some coaches believe athletes can be taught to protect themselves at a younger age.
"Something that has gotten better is the education as far as the technique and teaching them proper tackling and how to not use their helmet as a weapon but to keep it up at all times," said Billy Chadwick, coach for the Wichita Golden Bulldogs.
Helmets were designed to protect against skull fractures, not concussions, and doctors recommend athletes continue to wear them.
