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.

Skepticism

October 4, 2011

One of the greatest catalysts of the environmental movement in Michigan was the rise of the middle class working family as our state industrialized in the early 1900s.  Forty-hour-a-week workers with good pay and benefits sought out clean rivers, streams, lakes and parks for recreation and relaxation during their weekends and vacations.  Many industries that created the jobs soon realized they had to provide their employees a clean environment as well.

Now as we struggle through a prolonged period of economic malaise in America, economists and politicians focus on what is needed to stimulate growth in the U.S. and world economies.  They appear to worship at the altar of economic expansion, few seeming to question if our planet can sustain the growth rates they pursue.  What price to our environment does a robust economy extract?

Of course, it is easier for a person with a job, insured benefits and a retirement program to question the obsession with economic growth; but a job without clean air to breathe and water to drink will not be satisfying for long.  So a healthy dose of skepticism about economic growth is needed.

As I read the scathing indictment of corruption in college sports in the October issue of The Atlantic Magazine, I kept thinking that a healthier dose of skepticism about ever-increasing hype might have avoided the crass commercialism and exploitation of what once was but may no longer be justifiably connected to institutions of higher learning.

And of course, a healthy dose of skepticism must be maintained by those in charge of school sports as we trend during difficult economic times in directions more commercial than our founding principles may have envisioned.
