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.
One Concussion Conclusion
August 25, 2017
After both the first and second years of collecting head injury reports from all Michigan High School Athletic Association member high schools for all practices and events in MHSAA sports, we cautioned people to refrain from making too many conclusions.
It’s too soon. We now have a baseline, but we will need several years before we can be certain that we’ve spotted trends or trouble spots.
Nevertheless, one observation screams out. Girls report two to three times the number of concussions that boys do. In basketball, soccer, and in softball compared to baseball, girls report two to three times as many concussions. That was true in year one; it remained true in year two.
It may be that girls sustain more concussions than boys, or that girls are more forthcoming in reporting than boys are, or both. In the past, researchers have published both conclusions.
In either case, it means we need to coach boys and girls differently, and we need to prepare coaches differently for boys and girls teams, as we are doing in the MHSAA Coaches Advancement Program.
