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.

Butterflies and Helicopters

July 9, 2014

I’m doing as much as I know how to attract butterflies to my garden. For example, I’ve planted a butterfly bush and milkweed plants. I do this because these plants are supposed to attract butterflies and bees, and I know butterflies and bees are essential to producing vegetables.

One of the greatest miracles any person can observe is to watch a butterfly emerge from a cocoon. It was as wondrous to me last summer as the first time I saw it occur when I was a young child, when I first saw a butterfly emerge with damp, shriveled wings. 

I was told then that we shouldn’t interfere, that we shouldn’t help the butterfly escape the cocoon and shouldn’t help spread the wings. We had to let the butterfly struggle. We were instructed that the struggle would give strength to the wings, and that would be essential to the butterfly’s survival.

Childhood is much like this, but too often helicopter parents intervene and interfere with the growth process and, ultimately, weaken their children’s ability to fend for themselves, to overcome adversity and to take flight.

Helicopter parents endanger our butterfly children.
