_Editor’s note: The following is a roundup of archival stories about concussions, including advice on how to recognize symptoms and explanations of why they can be so dangerous to children._

A study published July 25 based on examinations of brains of deceased NFL players reported disturbing news about the prevalence of concussions. Of 111 brains examined, all but one were

found to have chronic traumatic encephalopathy, or CTE, the degenerative brain disease caused by repeated blows to the head. The concerns are many. Evidence has been growing that concussions

among young athletes occur far more frequently than reported. This leads to concerns among parents for the safety of their children who play football, soccer and other sports in which they

could suffer head injuries. The report also raises questions about the role and function of professional football in our society. On the one hand, we love it, with Super Bowl Sunday having

become close to a national holiday and one of the most important advertising days of the year. But on the other hand, the number of injuries to the heads of these professional

athletes-entertainers is becoming as hard to ignore as a penalty flag on a game-winning touchdown. Yes, there are red flags, some argue, and then there are sirens – and in too many cases,

they are coming from ambulances transporting wounded football players. WHAT DO PARENTS NEED TO KNOW? Youth sports are a major part of childhood and adolescence, with an estimated 44 million

children playing sports each year. Many parents and teachers actively encourage sports so that kids will stay physically active. In light of the growing concerns around concussions and brain

injury, parents need to know that brain injuries can occur in many ways, explained Cindy Trowbridge, an associate professor of kinesiology at the University of Texas Arlington. The young

brain differs from the adult brain in ways that place it in particular peril. > “Children have smaller brains in relation to their skulls. > Compared to an adult, the young child brain

 has less mass and more > cerebrospinal fluid between the brain and the skull. By way of > analogy the child’s brain is like the egg yolk in an egg – there > is room for it to move.

 Because children’s brains have less mass > in relation to the skull, their brains experience more acceleration. > This means the brain can hit the skull with more force.” Gerald

Zavorsky, an associate professor at Georgia State University, explained last year just how under-reported concussions are among children. This is a big concern not only because of the health

effects but also because of how children’s ability to learn can be impaired. > “[One] study estimated that between 1.1 million and 1.9 million > concussions occur in children each 

year. That is far greater than > the number of children with concussions reported by emergency > departments; their records indicates the number ranges between > 115,000 to 

167,000.” Zavorsky went on to detail how this not only affects children’s health but also their learning. > “While rare, the effects of an untreated concussions can stay with > a child

 for many years. The effects can cause brain malfunction, > including a lack of focus and difficulty learning. Also, the risk > for longer-term problems increases if a child has a 

second > concussion… It is imperative to avoid sending a child back into a > game or activity if head trauma has occurred.” WHAT DO KIDS NEED TO KNOW? Young athletes need to be

encouraged to report a blow to the head, dizziness and, indeed, any type of pain they feel, wrote J. Douglas Coatsworth of Colorado State University. But adults need to help children change

a culture of “taking one for the team,” or continuing to play when injured. > “We know characteristics of youth athletes, such as the knowledge > they have about concussion, their 

attitudes about how serious > symptoms are and their beliefs that if they report a concussion they > will let the team down, all influence whether they will report > concussion 

symptoms.” Coatsworth is conducting a study to see whether changes in adult attitudes could affect how children report. > “Hiding symptoms of concussion and continuing to play in sports

> can result in subsequent injury, delayed recovery, delayed access to > treatment and risk of catastrophic injury. An Institute of Medicine > and National Research Council report 

on youth concussion concluded > young athletes face a ‘culture of resistance’ to reporting.” WHAT OUR SOCIETY MAY NEED TO CONSIDER Even though football is one of our nation’s most beloved

pastimes, some people are wondering not only whether they should forbid their children to play the game but even whether to allow them to watch it. In turn, they also wonder whether they

themselves should watch the games. Kathleen Bachynski, a doctoral candidate in sociomedical sciences at Columbia University Medical Center, explained how this can be a difficult decision.

> “Parents generally have final say over the activities their kids > participate in. Should they…forbid their children from playing > football? Unfortunately, there’s no simple 

answer. Instead, a host > of issues – cultural, social and physical – need to be > weighed.” And, Trowbidge reminded parents that the discussions go beyond football. Children can be

injured in many types of activities and parents should know that concussions can occur from trauma other than a blow to the head.
