According to a recent study, parents should be concerned about even mild concussions.
Initially, those with concussions had thinking and memory test scores that were 25 percent lower than those in healthy people. One year after injury, however, while the scores for those with and without concussions were similar, those who had had brain injuries still had evidence of brain damage on imaging tests, with clear signs of continued disruption to key brain cells.
It sure seems like the more we learn about concussions, the worse it gets. I can’t help but wonder what that’ll do for participation rates in some sports for kids. On the other hand, kids can get a mild concussion from a lot of non-sport activities too!
