Web Chat: The Risks Of Concussions In Youth Sports

The problem of concussions in professional sports gets a lot more attention now than it used to, especially in the NFL and NHL.

But Dr. Robert Cantu worries that concussions in youth sports aren't taken as seriously. Cantu is a clinical professor of neurosurgery at the Boston University School of Medicine, and he's co-author with Mark Hyman of the new book "Concussions and Our Kids: America's Leading Expert on How to Protect Young Athletes and Keep Sports Safe," excerpted below.

They write that sometimes in youth sports there's a "walk it off" attitude among some players and parents and coaches. And that means head injuries in young athletes sometimes go overlooked, even though they can be especially detrimental in kids.

Do you worry about risks to your child in his or her sport? How can we make youth sports safer?

Youth sports expert Mark Hyman weighed in on those issues and more in a live web chat, watch a replay below.

What is a Concussion?

“We need to do something now, this minute. Too many kids are at risk.”
— Dr. Ann McKee (Time)

“We still have this culture where it’s hard to convince people that a concussion is a very serious brain injury.”

— Dawn Comstock, principal investigator, Center for Injury Research and Policy, The Research Institute, Nationwide Children’s Hospital, Ohio State University (Time)

IN THE LATE 1950s, I was a student at Cal-Berkeley and a member of Cal’s baseball team. We were playing Stanford one afternoon, and I came to bat. This was the dark ages before batters wore helmets with ear flaps. Our protection—if you can call it that—was a flimsy liner inside our felt caps.

A pitch came inside and tight, and I didn’t react as quickly as I needed to. The ball caught me flush on the side of the head. The cap and the hard liner were just about worthless. The force of the blow stunned me, and I wobbled a bit as I made my way down the line to first base. This didn’t seem to bother anyone as much as the blood trickling from my ear. It wasn’t really coming from my ear—the force of the pitch had shattered the cap liner, which sliced into my scalp.

The coaches didn’t know that, of course. They took one look at me and thought, “My God, Cantu has a skull fracture! Get him to the hospital!”

In those days, it wouldn’t have occurred to anyone in either dugout that I might have had a concussion. Even at the hospital it wasn’t diagnosed. It’s only looking back with years of experience in this field that I can say—based on my symptoms, which included not knowing where I was for a while, lightheadedness, and a violent headache—that I certainly had a concussion.

We’ve come a long way since those unenlightened times. Now head trauma in sports is a topic that leads nightly newscasts and is debated at every level of amateur and professional sports. I knew that concussions had become something of a national obsession when Jerry Seinfeld built an entire monologue around the question “Why did we invent the helmet?” Normally, there isn’t a lot of humor associated with head trauma of any kind, but Seinfeld’s take is amusing. First, he says, we invented sports, the main feature of which is slamming our heads into each other over and over. Then, “We chose not to avoid these activities but to make little plastic hats so we could continue our head-cracking lifestyles.”

A Concussion Is...

The word derives from the Latin concutere for “to shake violently.” Concussions are just that—a shaking of the brain inside the skull that changes the alertness of the injured person. That change can be relatively mild. (She is slightly dazed.) It can be profound. (She falls unconscious.) Both fall within the definition.

According to the Centers for Disease Control and Prevention, almost four million sports- and recreation-related concussions are recognized every year, with many times that number occurring but going unrecognized. For young people ages fifteen to twenty-four years, sports are the second leading cause of traumatic brain injury behind only motor vehicle crashes. According to research by the New York Times, at least fifty youth football players (high school or younger) from twenty different states have died or sustained serious head injuries on the field since 1997. One study estimates that the likelihood of an athlete in a contact sport experiencing a recognized concussion is as high as 20 percent each season. In my office, there is a very discernible cycle in the number of concussion patients. In the fall (football season) and winter (ice hockey) the numbers go up, sometimes exceeding fifteen new young athletes with a concussion per week. In the spring and summer, they slide back down.

How They Happen

Concussions happen to all types of athletes—young and old, boys and girls, and in every conceivable sport. In a typical year, I see hundreds of children and adolescents in my office. We see more than athletes, of course. Some patients have suffered concussions in traffic accidents, mishaps around the house (they walked into a door), or a slip and fall in the grocery store.

In a chapter later in this book, I offer observations about concussions in “non-collision” sports such as volleyball and tennis that parents—for good reason—do not think of as posing a great risk of concussion. However, there is risk in every sport. I would have to think a long time before naming one that has not sent a single patient to our office at Emerson Hospital in Concord, Massachusetts.

Many patients get well over two to three weeks, pretty much as expected. Other cases take unexpected turns. Mario was an eleven-year-old kid making one of those typical recoveries. After his concussion, he had a number of symptoms. We held him back from sports, gym, and physical activity. He was also under restrictions regarding his schoolwork. Just as he was about ready to resume normal activity, Mario hit his head on a bedpost and suffered another concussion. The process started all over again. I can’t count the number of stories like that. Unfortunately, they happen a lot.

Concussions in sports occur when an athlete is slammed and makes sudden and forceful contact. That contact can be with the ground, court, or pool deck. It also can be with a batted ball, a thrown ball, a kicked ball, a goalpost (football), the boards (hockey), the scorer’s table (basketball), and of course another player. Dylan Mello, a high school soccer and ice hockey player from Rhode Island, suffered a severe concussion in a collision with a player who smashed him with the plaster cast on his arm.

Concussions can and frequently do occur without any contact with the head. Rather, the player’s body receives a jolt that causes his shoulders and head to change speed or direction violently. It’s the whiplash effect. Inside the skull, the brain shifts in the cerebrospinal fluid and bangs against the inside of the skull. Even falling from five or six feet and landing upright, if it’s unexpected, and therefore jarring, can send a shock through the spine and shake the head with a force that may cause a concussion. Concussions that are the most damaging to the brain tend to be the ones that involve a direct blow to the head, however. When you’re struck in the head, the forces generated are about fifty times greater than being struck in another part of the body.

With such a blow, the brain pushes forward until it crashes into the skull, reverses, and bumps against the back of the skull.
