Knocked Out - Great Journalism on Concussion


Across the country, people have awakened to the sometimes irreversible damage of concussions, especially in high-impact professional sports. With much of the attention focused on the National Football and National Hockey leagues, the Houston Press — following a months-long, nationwide investigation into the consequences of concussion on youth athletes, who are bigger and more aggressive than in past generations, and often play year-round — has found the following:

• The effect of a concussion on kids can be much more devastating than on adults. Doctors say that until a person is in his early to mid-20s, his brain is not fully developed and can't take the same level of trauma as an adult brain can.

• Postmortem analysis, the only surefire way to measure concussions' devastating effects, shows that repeated blows to the head may be linked with Alzheimer's, Parkinson's, ALS and a number of other fatal diseases.

• An athlete who doesn't exhibit outward signs of a concussion (headaches, dizziness, vomiting, temporary amnesia) can still experience changes in brain activity similar to those in a player who has been clinically diagnosed with a concussion.

• The ImPACT test, widely regarded as the go-to neurological exam to measure concussive blows, doesn't always accurately gauge a player's readiness to return to action. And you can cheat on it.
