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.
Health Histories
September 4, 2012
Eighteen months ago we completed two new preparticipation physical examination forms: (1) a two-sided card delivered without charge to schools in whatever quantity they need; and (2) a four-page form that is downloadable at MHSAA.com.
Both are improved from the previous card in that they ask more about family and student health history which, more than any cursory exam, helps identify potential health risks before participation. Both were developed with the cooperation and consensus of a diverse panel of medical experts assembled by the Michigan Department of Community Health.
At schools’ requests, the MHSAA has distributed more copies of the two-sided card than there are students enrolled in MHSAA member schools; so we know the form has widespread use. But still, this particular form is not required, which allows schools with a special local resource to utilize something they like better, and this also allows families with special needs to use the documents that best meet their child’s circumstances.
The take-away on this topic is that today’s standard of care is a comprehensive physical with detailed family history prior to first participation in school sports and, thereafter, more cursory annual exams, except when the student has had an injury or illness that requires more review.
