Obama: Too Little Info About Youth Concussions

Obama is calling attention to youth sports concussions during a White House summit with coaches, students, parents and medical professionals.

Obama says there's a huge public interest in having kids participate in sports. He says it's a central part of American culture that teaches teamwork.

But Obama also says there's both concern and uncertainty about sports concussions. He says it's not limited to football.

Obama says there still aren't solid numbers and at every level, experts are still trying to grasp the scope of the issue.

Obama says people must learn to recognize and respond to concussion symptoms. He says awareness about the problem has improved, but not by much.
