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.
Controlled Fires
July 24, 2012
Forest fires have recently been scorching the United States with unusual reach and rage. Infernos in the Upper Peninsula of Michigan, as well as Arizona, Colorado, Idaho, Nevada, New Mexico, Oregon, South Dakota, Utah and Wyoming, have made news in our state.
Behind the headlines of the lightning-ignited 150-square-mile devastation near Fort Collins, Colorado is the analysis of forestry and conservation experts that it has been the absence of small fires that has helped to fuel the large fire. Turns out that Smokey the Bear’s campaign to prevent forest fires may be partly at fault.
In most of life, little problems here and there help to avoid larger problems later. The little fires consume the fuel that would feed a catastrophic conflagration exploding out of pent-up fears or frustrations or long-festering problems.
Even those who work in the “prevention business” – whether that’s the US Forest Service or a statewide athletic association – must tolerate a few fires. They can have positive, productive effects, one of which is to keep small problems from growing large and more destructive.
