I am a pediatric neurosurgeon at Wake Forest University Baptist Medical Center and I love sports. Sometimes these two passions collide.
I grew up playing soccer, basketball, baseball and rowed crew. I also have three children, including two boys, ages 6 and 8, who play Pop Warner football. But I worry about youth sports as much as I love the games because of the risk of head injury. That's why, when I'm not in the operating room, I've been on a mission to raise awareness about the signs and symptoms of traumatic brain injury.
I'm also working on a research project with the football teams at Virginia Polytechnic Institute and Wake Forest University to better quantify the relationship between a hit on the playing field and a brain injury.
Let me start with some figures. According to the Centers for Disease Control and Prevention, each year U.S. emergency departments treat an estimated 135,000 children ages 5 to 18 for sports-related brain injuries. Most of these injuries are concussions, and the children recover. But the prognosis for children who suffer repeated concussions, even mild ones, is unknown. It's hard to imagine your child as a disabled, middle-aged man, but repeated concussions could put a child at risk for such crippling conditions as early onset dementia, Parkinson's disease and other neurological disorders no one wants to think about on the sidelines at a football game.
Overall, more than 1.7 million people a year injure their brains in an accident, a fall or on the playing field. About 75 percent of these brain injuries are concussions or other milder injuries. But some are deadly. About 52,000 people a year die from brain injuries and 275,000 are hospitalized.
Serious brain injury is pretty easy to diagnose. A player gets hit on the soccer field and loses consciousness; everyone knows to call an ambulance. But what about the subtler injuries? Two players collide on the basketball court. One of them is your best shooter. He looks a little dazed, but says he's okay so you keep him in the game. Later, it turns out he can't even remember knocking heads with the other player. He can't remember score and when he gets home he has a splitting headache. Sounds like a concussion to me. What he needs is rest --- lots of it. No playing time. No school. No TV. His young brain needs time to heal.
But our culture works against taking a player out of a game, let alone excusing him from practice for a couple of weeks. Young athletes are supposed to be tough. Coaches - and parents - expect them to keep playing, in spite of injury.
I hear too many youth football coaches say, "He just took a ding," when the fact is the player was hit hard enough for a brain injury. He needs rest, not playing time. Young brains are still growing. That's why children and teenagers have such an enormous capacity to learn. Their growing brains also make them more vulnerable to injury. Children and teens are more likely to get a concussion than an adult. And the younger they are, the longer it takes for them to recover.
My colleagues in Sports Medicine and Neurology at Wake Forest Baptist run a sports concussion program where they've developed technology to more accurately diagnose concussion. And I'm working with a team of researchers at Virginia Tech on a study that will take some of the guesswork out of diagnosing concussion on the playing field. We've installed a simple device inside the players' helmets that measures the force with which they're hit and transmits that data to the sidelines. The device, known as an accelerometer, fits snugly in the top of the helmet. The team doctor can monitor from the sidelines. When a hit registers a high level of force, he'll take the player off the field and examine him for signs of a concussion.
Already we've learned some interesting data. For example, different players in different positions sustain different kinds of blows and may need different kinds of protective gear. Linemen sustain many low-impact frontal blows. Wide receivers sustain fewer blows, but they're harder. And when a linebacker gets hit, the force is generally higher than when a lineman gets hit.
My hope is that eventually all football helmets will be equipped with devices that measure the force of a blow. We'll provide coaches with hard data, so they know that if a player gets hit at a certain force he needs to come out of the game and rest. The hope is to be able to say, "That guy had a hit. Even though he's not showing signs of concussion, he needs to be checked out before another play." Until then, I'll be preaching prevention.
The website for Brenner Children's Hospital includes lots of information about brain injury for coaches, parents and young athletes: www.brennerchildrens.org/. I urge anyone involved with youth sports to learn about the symptoms. The main ones to watch for are confusion, memory loss, dizziness, blurred vision, headache and nausea. Some of the subtler symptoms include moodiness, trouble sleeping and anxiety.
When I was a resident in training no one wanted to take care of concussions. They are too subtle, too hard to diagnose. You can't see a concussion on an MRI and there's nothing to operate on or remove. The only treatment is rest, until all the symptoms clear up. When I say rest, I mean no reading, no watching TV, no video games.
Then you ease the child back into a normal routine after the symptoms have cleared - even if that means missing the championship game or the practice that will give him a shot at starting next season.
Often young players and their parents don't want to take my advice. They want their child to play - in spite of a lingering headache, in spite of an injury to their growing brain. I understand. Remember, I love sports as much as the next guy. But I have a rule for my own boys. If either one suffers a concussion at this tender age, he's done with football. The risk for future complications is too great. That's their dad, the neurosurgeon and sports lover, speaking.
