NFL concussion expert Dr. Richard Ellenbogen told Popular Science that he doesn't want to worry about the past and, instead, wants to deal with the future of head injuries.
Ellenbogen, a professor and chair of the department of neurological surgery at the University of Washington, is the co-chairman of the NFL's Head, Neck and Spine Committee. He talked about what his committee's work entails, what the NFL is doing to be safer and what's next for concussion technology.
He said he has seen big improvements in dealing with concussions since he joined the committee in 2010.
Ellenbogen said he wants to move forward rather than worry about what happened in the past.
As for what to expect in the future, Ellenbogen said we could see major changes in helmets. We definitely will see changes in how head injuries are diagnosed and treated.
