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.

Simons Says

December 12, 2014

As an almost inveterate traveler – one who begins planning his next adventure to sweeten the sadness during the return trip of the current adventure – I took special note of and pleasure in this statement of Eric Simons in his book Darwin Slept Here:

“Optimism may be one of the biggest benefits of travel. When you spend all your time in a small area, trekking back and forth to work, getting all your news on the Internet, it’s easy to think the world is a lot worse off than it is. Then you get out in it, even for a short bit, and you get a summit view or find a friendly person who cares about nature just like you do, and then even when you go home, you remember: Hey, it’s not all bad. We’re really doing ok.”

When I see advertisements that promote travel as an escape, I cannot agree. For me, travel is a change from the daily routine, but it’s hardly an escape. In fact, I see more sights, hear more sounds, smell more scents and taste more flavors when I travel. I interact with countless more people – in airports, markets, parks, museums. But even moments of isolation – perhaps on a remote beach or trail – are somehow richer, more contemplative, when traveling.

It is not escape but engagement with new cultures and customs that travel causes; and it creates opportunities for personal reflection that routine obscures.

As Simons says, “Traveling connects us to the world and renews our capacity to wonder.”
