The number of sports-related concussions reported by young athletes is on the rise, prompting awareness campaigns from athletic and medical groups, as well as proposed federal legislation to set minimum standards for concussion management in public schools.
Concussions are caused by a jolt to the body or a blow to the head that causes the head to move rapidly back and forth. Concussion symptoms include dizziness, nausea, confusion, slurred speech, and memory problems.
Estimates of brain injuries suffered by people of all ages during sports activities range from 1.6 million to 3.8 million a year. Further studies on high school football players specifically range from 43,200 to 67,200 annually.
The and the this month launched a campaign to educate athletes, coaches, teachers, and parents about concussions. Their efforts coincided with introduced last week from the U.S. House 91制片厂视频 and Labor Committee that would require schools to develop a plan for concussion safety and management, implement an 鈥渋f in doubt, sit it out鈥� policy, and provide supports for student athletes recovering from concussion as they return to school and play. Rep. Timothy H. Bishop, D-N.Y., is the bill鈥檚 sponsor.
Those moves come in the wake of several recent events that have put concussions in the news.
In April, a 21-year-old University of Pennsylvania athlete who committed suicide was found to have had early signs of chronic traumatic encephalopathy, a brain disorder seen in people who have suffered repeated head trauma. Though the onset of the disease cannot be directly tied to the suicide, the disorder is linked to cognitive impairment and depression.
In May, the U.S. Government Accountability Office, the investigative arm of Congress, released on concussion in high school sports that said there was no mechanism to track an overall estimate of occurrence, but that the injuries may be underreported because athletes don鈥檛 want to be removed from games.
Four months later, published in the September issue of the medical journal Pediatrics noted that visits to the emergency room for concussions for children ages 8 to 19 had doubled from 1997 to 2007. This increase came despite an overall decline in participation in organized team sports, the study noted.
Last year, Rep. William J. 鈥淏ill鈥� Pascrell, D-N.J., introduced the , which would direct the U.S. Department of Health and Human Services to establish concussion-management guidelines and pay for computerized preseason baseline and post-injury neuropsychological testing for student athletes. That bill has been referred to the health subcommittee of the House Committee on Energy and Commerce.
鈥楳acho鈥� Mentality
Experts believe at least some of the increase in concussion diagnoses may be due to greater awareness of the problem. Coaches and athletes are less likely to dismiss a head injury as something to 鈥渟hake off.鈥�
But then there are well-publicized situations where the monitoring system appears to break down. In the Philadelphia Eagles鈥� season opener earlier this month, linebacker Stewart Bradley stumbled and fell to the ground after sustaining a hard hit to the head after a play. Quarterback Kevin Kolb also suffered a concussion in the game. Both briefly returned to play before being taken out.
鈥淔ootball is such a macho sport. There鈥檚 a pervasive mentality in that sport鈥� to ignore injuries, said Mike Carroll, the head athletic trainer at the 1,000-student Stephenville High School in Stephenville, Texas. 鈥淚 really have to emphasize that this is not something you can walk off.鈥�
Mr. Carroll, who has been an athletic trainer for 20 years and at Stephenville High for eight, doesn鈥檛 have to fight too hard with the coaches when it comes to holding students out who have received concussions.
But some students are still slow to report their injuries. Recently, one student who was injured in a Thursday night game didn鈥檛 report the problem to the athletic trainer until Friday morning when his father noticed troubling symptoms.
鈥淎s the athletic trainer, I can鈥檛 be everywhere. It鈥檚 important that everyone in the circle [around the athlete] be aware of these injuries and what they can mean,鈥� Mr. Carroll said.
The riskiest sport for concussion is football, according to the Pediatrics report. However, soccer, lacrosse, ice hockey and cheerleading are also sports where participants face a concussion risk. In some sports, such as ice hockey, female athletes report a higher concussion rate than their male counterparts.
Experts suggest the disparity may be due to physiological differences that make women more prone to concussion injuries, and female athletes being more willing to admit to injury.
Steven P. Broglio, an assistant professor of kinesiology and community health at the University of Illinois at Urbana-Champaign, has studied head impacts during high school football. He noted that the force of impacts at the high school level exceeds those at the collegiate level.
One hypothesis, he said, is that high school athletes may not have yet developed the musculature that can help protect against sharp head movements.
鈥淲orse yet, you have the worst medical care at that level,鈥� he added. College and professional athletes have medical staff at practices and games. Those personnel may not be present at the high school level, he said.
He supports having athletic trainers both at games and practices. 鈥淭he injury rates are a lot higher in games. Kids hit harder,鈥� Mr. Broglio said, 鈥渂ut you practice a lot more than you have games.鈥�
Once a child has a concussion, administrators and teachers have to be aware that transitioning back into school may take time, said Ruben J. Echemendia, a neuropsychologist in State College, Pa., who is chairman of the concussion-management groups for the National Hockey League and Major League Soccer. Mr. Echemendia sees high school athletes as well in his private practice.
鈥淭heir workload has to be adjusted. A lot of administrators don鈥檛 get that, they think they鈥檙e trying to milk it or play up the symptoms. But the student actually has a disincentive to exaggerate, because they know they鈥檙e not going to play,鈥� Mr. Echemendia said.
