Head Trauma and Learning
November 23, 2012
Researchers at my alma mater have joined their voices to the growing chorus of concerns about the effects of repeated blows to the head.
A study of the cognitive effects of head impacts on members of Dartmouth College football, hockey, track, crew and Nordic ski teams compared before and after season results on learning and memory skills. Participating athletes also came from Brown and Virginia Tech.
-
22 percent of athletes in contact sports had lower results on learning and memory skills tests after their season.
-
Only 4 percent of athletes in non-contact sports posted lower test results.
The researchers caution that it is unknown at this point how long these negative effects may last, but they also note there is some correlation between test results and how hard the athletes were hitting heads.
This adds to the mounting evidence that rules writers, program sponsors, coaches and officials must look for and implement a variety of measures to reduce the frequency and severity of head impacts in both practice and competition in all sports.
What We’ve Learned
July 12, 2017
Here’s some of what we’ve learned from the first two years of having all Michigan High School Athletic Association member high schools report suspected concussions and make follow-up reports for each.
First and foremost, concussions are of concern beyond football and boys. While football – the highest participation sport – has had the most concussions, the sports that follow are girls basketball (second) and girls soccer (third).
Which leads to the second lesson: Girls report two to three times as many concussions as boys in basketball and soccer, as well as in softball compared to baseball.
Which leads to the third lesson: Whether girls actually experience more concussions than boys or are more forthcoming than boys in reporting suspected concussions, coaches need to coach and communicate with females differently than males; and coach educators must prepare coaches to interact differently with boys and girls.
We’ve also learned that more than 80 percent of concussions caused the athlete to be withheld from activity for six days or longer; and again, there was a tendency to withhold girls longer than boys. In any event, the data suggests that people are taking concussions seriously and not rushing students back into practices or contests.
The data also reveals that more than two-thirds of reported concussions arise from competition, and less than one-third occur during the many longer hours of practice. This is a reversal of the data we were provided a decade ago based on smaller samplings from other states; and this suggests that coaches are finding ways to teach skills and conduct drills without requiring as much player-to-player contact as in the past.
That’s good news. But we’ve also learned from the first two years of data that there is still more to research, more to learn and more to do to make our good games even better.
