The brain is vulnerable to trauma
I feel like I've opened the proverbial can of worms, finding, in this case, a topic that keeps expanding. I started with reading an article in The New York Times about the death of a professional hockey player, but I quickly delved into the medical literature.
I've spent much of the day reading article after article on traumatic brain injury (TBI), which can be mild or severe, and another entity called chronic traumatic encephalopathy or CTE, one that's frequently been in the news over the last two years. Let's start with TBI. I'll be writing about teens and younger kids. I'll deal with CTE in another post focused on adults.
A Center for Disease Control and Prevention (CDC) report in the most recent edition of the Journal of the American Medical Association reviewed nonfatal TBI related to either sports or recreational activities in kids age 19 or younger. The numbers involved were staggering, nearly 175,000 per year being seen in Emergency Departments (EDs).
A large majority of those sports and recreation-related TBI ED visits were by boys and the annual total of those ED trips increased markedly during that nine-year time frame. They were injured biking, playing football, soccer, basketball or while engaging in miscellaneous playground activities. They went to the ED in smaller numbers for injuries suffered in many other activities, including horseback riding, ice skating, ATV riding, tobogganing and even golfing (here the injuries included those related to golf carts). Surprisingly, skateboarding accounted for only a fourth of the ED visits for biking and football accidents and TBI was less frequently seen.
A helmet is a good start
As my wife and I drive around town, we often see college students riding their bikes at night while helmet-less and light-less. I fear for their brains.
There's another, less well-accepted entity, so-called "Second Impact Syndrome." I read an article about this in a February 2009 article by two authors on the faculty of the University of California, Irvine School of Medicine. In this scenario athletes who've had a TBI then have a second brain injury when they go back to playing their sport far too quickly. The initial injury may have been relatively mild; the recurrent trauma may kill them in a matter of minutes.
Another review of this syndrome said 94 catastrophic head injuries had been reported in American high school and college football players in a 13-year time frame, 92 in high schoolers. Seven of ten had a prior concussion in the same football season; over a third played with continuing symptoms.
This speaks to the crucial question of when an athlete (or a bike or horseback rider) who has suffered TBI should return to their sport/activity. Last night I called a younger friend who had been bucked off his spooked mare and suffered a concussion eight days ago. He was still having headaches and agreed with me that it was far too soon to get back on his horse.
A new CDC program called Heads Up offers TBI guidelines for coaches, parents and physicians.
