Anyone catch the news item on a new way to check for concussions? I believe the doctor that came up with this equipment is located in Seattle. By looking at your eyes the machine can tell if your eyes are tracking together. When a person injures their brain their eyes will not track as a pair. The doctor likened it to the old cartoons that showed a character getting beaned and then their eyes would roll around.
In the testing so far this new machine can identify a concussion even if a scan shows clean. Sounds very promising.
