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.

Summer Football Safety

July 23, 2018

(This blog first appeared on MHSAA.com on June 23, 2017.)


Across the U.S. this summer, school-age football players are flocking to camps conducted by colleges and commercial interests. They get outfitted in full gear and launch themselves into drills and skills work.

Unlike the start of the interscholastic football season, the players usually do this without several days of acclimatization to avoid heat illness, and without limits on player-to-player contact to reduce head injuries.

Required precautions of the school season are generally ignored at non-school summer camps.

One notable exception to this foolish behavior is found in Michigan where the Michigan High School Athletic Association prohibits member schools’ student-athletes from using full equipment and participating in full-contact activities outside the high school football season. This is not a recent change; it’s been the MHSAA’s explicit policy for more than four decades.

And it’s a policy that has never been more in style and in favor than it is today.
