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.

Panama Points

January 25, 2012

Author David Kord Murray opines in Borrowing Brilliance that almost all good ideas are borrowed, and the farther afield one roams from the topic at hand the more useful the idea may be (and the more brilliant it may appear to be).

So it didn’t surprise me to discover useful ideas for modern day leadership and management in a book written in the 1970s about a period many years before that – David McCullough’s history of the building of the Panama Canal titled The Path Between the Seas.

I learned first that the primary task of this huge project was not what it appears to be. It was not primarily an engineering feat, but medical. Not removing dirt, but disease. Not conquering the largest obstacles, but the smallest insects. It was only after the diseases were understood and controlled that the construction could advance and the project could be completed.

Second, I learned that once the construction was begun, there was a bigger challenge than digging the pathway clear. It was removing the unwanted dirt and debris to other places. It wasn’t the front end of the project alone that mattered, but the back end as well: where to put the hundreds of millions of tons of rock and dirt on or around this narrow isthmus of land.

For every project there is need to assess what the underlying issues are that might get in the way of accomplishing the more apparent tasks before us.

And for every project there is need to fully assess consequences. We don’t want merely to move the dirt around, creating new problems as we do so.

I will be considering these thoughts as I soon see with my own eyes the Panama Canal, constructed over four decades and completed almost 100 years ago. And gratefully, I will be fully immunized for diseases largely conquered during the completion of this engineering marvel.
