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.
Early Results
May 17, 2016
On May 3 we released a preliminary summation of results of winter season concussions reported by Michigan High School Athletic Association member schools. It was reported that 48 percent of the concussions reported were to female athletes, who make up only 38 percent of all winter season participants.
We will be digging deeper into the reports and providing a more comprehensive summary for all three seasons – fall, winter and spring; but we already see one suspected theme is being confirmed: more concussions reported for girls than for boys.
Even though girls’ participation in basketball is 36 percent lower than boys in MHSAA member high schools, there were 88 percent more concussions reported for girls than boys in that sport this past season.
We hope that researchers will step forward to inquire into the physiological, psychological, social and other reasons for the significant disparity in concussions reported by males and females; and perhaps they will be able to suggest what administrators, coaches, rule-makers and others might do in response to that research.
We expect that other themes suggested by the data from this first-year reporting requirement and then year-over-year comparisons will create interest in other research, all of which will help make school sports an even healthier experience for boys and girls than it already is.
