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.
Domestic Solutions

Kudzu was introduced to this continent in the late 1800s to control soil erosion in the southern United States. Now, this fast-growing Asian climbing vine is choking out all other vegetation. This seriously invasive species is growing at a rate faster than 150,000 acres each year in spite of millions of dollars spent to control it.
Asian carp were introduced to this continent one hundred years later, primarily for the purpose of cleaning commercial catfish ponds in Arkansas. They escaped into the Mississippi River and have proliferated, eating voraciously and growing to immense proportions. They now threaten the commercial fishing industry of the Great Lakes.
When we invite what appear to be relatively easy outside solutions to difficult internal problems, we invite more serious problems.
Whatever issues we face in school sports are best addressed by schools themselves using the resources at hand. No outside agent can be introduced to solve the problems we confront. No software is the silver bullet, and no sponsor provides the sustenance to keep educational athletics not only alive, but well.
It is up to us alone – administrators, coaches, officials. Using the natural resources right in front of us. Here and now.
I’d prefer to see the kudzu and carp when I travel in Asia, not America.
