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 & Safety Journey

September 30, 2014

The Michigan High school Athletic Association is a bit more than halfway through an eight-year effort to shine the light on, and provide leadership for, four health and safety issues for school sports.

Four and five years ago our health and safety focus was adding more health history to the preparticipation physical examination process and printed forms. With the essential assistance of the Michigan Department of Community Health, this was done, and it earned widespread, positive reaction from Michigan’s diverse medical community.

Two and three years ago our focus was the head; and our early adoption of an all-sports return-to-play protocol after concussion symptoms became a national model.

Last year and this, heat and hydration has been the focus. The MHSAA imposed on its own tournaments, and recommended for member schools’ practices and contests, policies to manage heat and humidity that include a reduction or modification of activities when the heat index reaches a certain level and cessation of all activities when the heat index reaches an even higher level.

Next school year and in 2016-17 the focus will be the fourth “H”: hearts. Tests for heart defects are expensive and results are often misleading, and the triggers of sudden cardiac arrest are unpredictable. Therefore, we will be pointing to the two actions medical authorities appear to agree upon most: (1) the need for planned and practiced emergency procedures, and (2) the need to have AEDs nearby, in good working order.

We urge MHSAA member schools not to wait for the MHSAA focus to make this a local school focus, and we recommend the MI HEARTSafe Schools initiative. See the HeartSafe Action Plan or the HeartSafe School information for details.
