Study: Kids Competing Too Soon After Concussions
By Sean Gregory

Too many kids are returning to the playing field too soon after a concussion. How many? According to an alarming new study, from 2005 to 2008, 41% of concussed athletes in 100 high schools across the U.S. returned to play too soon, under guidelines set out by the American Academy of Neurology. The 11-year-old guidelines say, for example, that if an athlete's concussion symptoms, such as dizziness or nausea, last longer than 15 minutes, he should be benched until he's been symptom-free for a week. The most startling data point--uncovered by the same researchers who in 2007 brought to light the fact that girls have a higher incidence of concussion than boys--is that 16% of high school football players who lost consciousness during a concussion returned to the field the same day.
The consequences of going back early can be dire. Last September, Jaquan Waller, 16, suffered a concussion during football practice at J.H. Rose High School in Greenville, N.C. A certified athletic trainer educated in concussion management wasn't onsite, and the school's first responder who examined Waller cleared him to play in a game two days later. During that game, Waller was tackled. Moments later, he collapsed on the sidelines. He died the next day. A medical examiner determined Waller died from what is called second-impact syndrome, noting that "neither impact would have been sufficient to cause death in the absence of the other impact." (See pictures of eccentric college mascots.)
Research indicates that younger, less developed brains are at greater risk of second-impact syndrome, which is why the new concussion study from the Center for Injury Research and Policy at Nationwide Children's Hospital in Columbus, Ohio, is so troubling. Submitted to a scientific journal for peer review, the yet-to-be-published study examined 1,308 concussion incidents reported by athletic trainers and found that in girls' volleyball and boys' basketball and baseball, more than half of concussed players returned to play too soon.
"These levels are way too high," says Dawn Comstock, an Ohio State pediatrics professor and co-author of the new study. She cites several factors that are driving the numbers. Not enough high schools have certified trainers who know how to deal with concussions--just 42% do, according to the National Athletic Trainers' Association. In some instances, overcompetitive coaches, who are not required to be trained in concussion management, are pushing players back onto the field. And too often the players themselves aren't reporting head trauma, with team spirit giving them too much of a warrior mentality.
Why is playing sports with concussion symptoms so risky? During a concussion, arteries constrict, slowing blood flow to the brain. At the same time, calcium floods the energy-producing portions of brain cells. That calcium plays a mean defense, blocking oxygen- and glucose-rich blood from replenishing neurons' energy supply. Brain cells get sluggish, and a concussed athlete who can't focus or suffers from slower reaction times is left more susceptible to a slew of other injuries, including another concussion. A second blow to the head could lead to more arterial constriction and more calcium infusions. "Concussion produces an energy crisis in the brain," says David Hovda, director of the Brain Injury Research Center at UCLA's David Geffen School of Medicine. "A second concussion will cause such an energy demand that it will overwhelm the survival capability of the brain." (See the Year in Health, from A to Z.)
That's why caution should be the name of the game. Robert Cantu, a neurosurgeon and concussion expert, insists that even after a mild first-time concussion, athletes must be free of all symptoms for at least a week, both at rest and during exertion, before returning to the field. Cantu's mantra: "When in doubt, sit them out."
But coaches, parents and medical personnel should expect resistance from athletes and remain on the lookout for those trying to downplay or hide less visible symptoms like headaches. What if a college scout was at the game you sat out because you got your bell rung? "For these kids, their goals in life sometimes revolve around athletics," says Todd Lipe, Waller's coach at J.H. Rose High School, who has promised to be more vigilant in detecting and managing concussions. (The school district did not blame any individual for Waller's death, though the first responder who examined him was relieved of his duties.)
Waller's death helped prompt an athletic-safety task force in North Carolina to recommend that all public high schools in the state be required to employ a full-time certified athletic trainer by August 2011. Meanwhile, after a high school student in New Jersey died of a brain injury suffered while playing football in October, New Jersey Representative Bill Pascrell introduced legislation in late 2008 that would set aside federal funding for computerized preseason baseline and postinjury neurocognitive testing for student athletes. This is a tough time to be asking for money, he says, but "when you compare this to the other injuries and ailments that we've responded to, it's embarrassing we haven't done more about concussions."
Given that concussions can be difficult to spot, the trickiest aspect may be getting kids to bench themselves after they're thumped. "You don't want to miss out," says Ryan Williams, a senior at Cibola High School in Albuquerque, N.M., who suffered two concussions this season and one last season. "You want to help your brothers." Of course, you can't help them, or yourself, if you don't know when to stay out of the game.

My brother got a new Nikon SLR today. It feels so good to be able to use such a cool camera, instead of some plastic compact.
Well said, mostly, but don't you feel you're oversimplifying?

Thank you for a great post
That was interesting but I can`t agree at all.
I'm not too sure what I want to pursue as a career. Its between optometry, ophthalmology and dentistry. Can I do a certain bachelor for 3-4 years to give me time to decide what I really want to do? Or does each career require a different bachelor degree?
ahahaha nice one tcchamps.
i think the athletic trainers are trained well (at least in TC - we love our trainer, Emily) to spot concussions and spot liars and real concussions. We get sidelined for a couple days/weeks depending on severity (most come from hell week -- you get 3,4 days but not a week).
This could explain "Academic Ineligibility."
Amen to that. Having kids that played contact sports and them having concussions - it takes a full month or so before the brain starts to recover.
One child suffered post concussive syndrome which was awful. I got lectured by the ER dr. that contrary to what the child says (I feel well I want to play) and what the coach says (They feel fine let them play) a good 6-8 weeks should be utilized.
