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.

It’s a Blizzard

March 18, 2015

Like the good people in Boston and other eastern cities and towns who couldn’t find anywhere to put all the snow they were getting this past winter, those in charge of school sports can’t find anywhere to put all the advice and expertise pouring down on us. We are well beyond the tipping point between too little and too much information regarding concussions.

In one stack before me are different descriptions of concussion signs and symptoms. I could go with a list as short as five symptoms or as long as 15.

In a second stack before me are different sideline detection solutions – tests that take 20 seconds to more than 20 minutes, some that require annual preliminary testing and others that do not.

In a third stack are a variety of return-to-play or return-to-learn protocols, ranging from a half-dozen steps to more than twice that number.

When I read that the National Football League, with all of its resources, was “overwhelmed by all of the expert opinion right now,” I was not comforted.

We have to cut through the clutter and provide our constituents clear and concise recommendations for the efficient education of coaches, student-athletes, parents and others; for electronic sideline detection solutions that are not only quick and effective in assessing injuries but also provide immediate reports and permanent records of concussions; and for protocols that place return to play well behind return to practice and further behind return to learn.
