I found it very interesting that researchers are suggesting that there may be a new test that could help with quick diagnosis. The King- Devick test would involve a one-minute test where the athlete would read a series of single-digit numbers on index-sized cards. After an injury, the athlete reads those cards again, and if the time is slower, it suggests there’s been a concussion.


The study results suggest the King-Devick test "is a strong candidate as a rapid, sidelines screening test for concussion," the authors write. It could be particularly helpful in identifying athletes who should be removed from play and assessed for possible concussion in such contact sports as football, soccer, hockey, mixed-martial arts fighting and boxing, according to a study published this week online in the journal "Neurology".

The more we are learning about the long term affects of concussions, the more likely it is that this type of early and affective diagnosis can make a difference.
