Improving Concussion Data

August 18, 2017

The Michigan High School Athletic Association’s 750 member high schools reported nearly 500 fewer concussions for the 2016-17 school year than the year before – 11 percent fewer.

That’s good news, but it’s not a trend we can bank on. It’s too soon to do that. There are too many variables that might explain or contribute to the decline from 4,452 to 3,958 concussions.

But of this we are certain: Schools are taking head injuries seriously. It is not a lack of concern or a lack of care in reporting that has led to the 11 percent decline.

It’s more likely the second year’s data is just better than the first year. The process was better understood. The numbers are more accurate.

Our data will become most reliable and useful when we have several years to compare and analyze. Only then will we really know where the trouble spots remain; and only then can those areas be most effectively addressed.

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.
