President Obama has called for improved research and protocols to address concussions in youth sports. Speaking at a White House summit on the issue, Obama said he likely suffered a concussion when he was young.

President Obama: “Before the awareness was out there, when I was young and played football briefly, there were a couple times where I’m sure that that ringing sensation in my head and the need to sit down for a while might have been a mild concussion, and at the time you didn’t think anything of it. The awareness is improved today, but not by much. So the total number of young people who are impacted by this early on is probably bigger than we know.”
