CHICAGO, May 24, 2012 -- Riddell Sports and USA Football today announced a renewed commitment to educating athletes and parents about concussion awareness. Starting today every new Riddell football helmet shipped to retailers and customers will include a hangtag offering concussion education that includes information from the Centers for Disease Control and Prevention (CDC) Heads Up program. Riddell's concussion education hangtag is the first of its kind among sports helmet manufacturers. "We have a longstanding commitment to player protection and continue to look for new ways to educate athletes and parents. As the leading manufacturer of football helmets, Riddell has raised concussion awareness through on-helmet labels and informational hangtags for over a decade," said Dan Arment, President of Riddell. "The new hangtag contains valuable information from the CDC and is the latest example of how Riddell will address concussion awareness with athletes and parents." Approximately three million American children age 6-14 play organized tackle football, placing it among the country's most popular youth sports. Since May 2009, 35 states and the District of Columbia have passed legislation to strengthen concussion education across youth and high school sports. Riddell's new hangtag will be attached to each helmet through an ear hole. The tag is titled "Raise Your Concussion Awareness" and lists concussion signs and symptoms, including CDC guidelines on what to do if a concussion is suspected. "Riddell shares USA Football's commitment to player safety and concussion awareness," USA Football Executive Director Scott Hallenbeck said. "Every parent who has a child playing youth football should ask their league two questions: 'How are your coaches trained to teach my child?' and 'Are your coaches educated on the symptoms and management of concussion?' Helmet hangtags will make certain that Riddell customers have a baseline of knowledge in this area and are directed on where they can learn more online." Riddell is the official football helmet and protective equipment partner of USA Football, the sport's national governing body in the United States.

As a new womens' lacrosse referee I initially had mixed feelings about the ongoing debate on the use of helmets in play. Listening to the discussion in referee training sessions that stressed the finesse of the game and the need of the referee to control or slow down play, verses the struggle I felt as a person having a medical degree and realizing the potential hazards of brain injuries, I tried to see both sides. Some people think that helmets will make the game more physical. But after my first official day as a referee standing on the sidelines watching my daughter’s middle school team begin their game, my beliefs became clear. Female lacrosse players need to wear helmets. During the first eight minutes of the game there were three injuries, one related to a child’s head and neck. This player had been checked from behind causing her neck to snap back. She then fell and hit her head on the turf. I witnessed every parent’s/referee’s/coach’s nightmare: a player down and seizing. To my dismay, this player returned to play in less than three weeks and went on to have another concussion and seizure. She is now barred from impact sports for the rest of her life. What I found out about my local school district surprised me and motivated me to try to educate parents and give people the best information possible. After speaking to the athletic trainers in my school district, I was made aware that high school students are given baseline concussion testing but younger players are not. We are now in the process of offering that testing to younger players. Also, while coaches can have in-person or online concussion training it seems that more could be done to help the coaches and parents become more informed about concussions. There are numerous issues that could explain the high incidence of concussions in women's lacrosse. One might be to consider the nutrition and health of girls playing the game today. Both men and women today are better nourished and physically stronger, faster and more powerful than the players of previous years. This has created a weight imbalance as some players can actually outweigh others by a large margin. The physics of combining speed and extra mass can lead to a dangerous combination. Equipment has also evolved to allow for lighter and faster sticks, causing unintended hits in some instances, I'm sure. Another factor is the increase in new players due to the popularity of the sport. Putting players of different skill levels in the same game can set up a difficult dynamic. It is important for players to be aware of their body position in space and reference to other players. This is a skill that comes with time and coaching. Coaching is another aspect of the game that helps teams work together better and control the speed of their game. Neck strengthening exercises can decrease the whiplash motion often caused by a hit to the cranial region. As for me, I have now completed my first season as a referee. I feel that helmets and proper body equipment in womens' lacrosse will make the game safer for everyone. My feeling is that there are too many factors that increase the potential for head injuries and we should mitigate them as best we can. While I realize helmets do not prevent concussions, I do believe they would be helpful to protect young women from unintended hits to the head.

SEQUIM, Wash. -- Battle-tested and a little weary from last fall’s high school football season, Travis Anderson, an experienced EMT and paramedic John Riley, understand the nuances of concussions. Athletes who — if they are conscious – say they are ‘fine,’ coaches who may not be sure an athlete needs medical attention, and parents told by ER staff that rest is the prescription for recovery, trying to make sense of the mountain of hospital medical bills. They’ve seen it all, and it’s not easy. First responders like Anderson and Riley from Clallam County Fire District #3 in Sequim, Wash., are a luxury for school districts around the country. Part of a crew made up of paid staff and volunteers, they wait in the corners until given the signal by a coach or referee, or a player goes down and stays there. Like other on-field personnel they can’t see every impact and don’t always know if an athlete is deteriorating on the bench after a big hit. They depend on an educated coaching staff and fellow teammates for their cues. Anderson said,”We’d like to be called sooner rather than later. If there’s any question, especially with a suspected concussion, call us.” Too little care Only about 42 percent of high schools nationally employ athletic trainers, a dismal number in the eyes of many concussion experts who continue to advise against any school district or private organization offering contact sports without proper sideline medical care. Given the budget crises facing many school districts, it is not surprising so few heed this advice. But the challenges in rural areas are even greater. Long distances separate football fields from hospitals and fire stations can serve several high schools. Resources are simply too lean. Many sports-related concussions “Our fire department provides sideline staff for high school football games, and as many junior varsity games as we can. We consider it part of our community service effort and quite frankly, we feel strongly about protecting our student-athletes and their futures,” said District #3’s Fire Chief, Steve Vogel. His first responders have been on the sidelines at Sequim School District's games since 1982. Chief Vogel’s staff has a long history dealing with sports concussions. Former Sequim football player Adrien Gault suffered a catastrophic brain injury during a game in 2006 and was airlifted to a Seattle trauma center where doctors gave him a four-percent chance of survival. He continues to work through his recovery. This past fall, a Sequim student suffered a brain aneurysm during a Friday afternoon PE class and died a few days later. That same Friday there were six significant concussions on the football field a few hundred yards away, said a well-informed source, turning the field into a war zone. Fire District #3 was there for it all. “There were more concussions during that one game than I’ve seen in my entire career, including my time as a running back in high school,” said Anderson. “It was a rarity.” Neither he nor Riley, who played tight end in high school remember suffering concussions during their football careers. They believe they’re seeing so many due to increased awareness trickling down from the NFL. Anderson said, “I think the attention on the concussion issue in the NFL is having an affect on all levels of the game, all the way down to the youngest players.” Emergency Medical Services for Children (EMSC) Guidelines and training for first responders come in the form of online education modules and concussion-related drills practiced several times a year. Soon-to-be-released state protocols developed by emergency room physicians, critical care nurses, EMTs, and others who make up the state committee of the federal Emergency Medical Services for Children program include a sports-concussion guide for first responders. Upon distribution, this document will provide a handy reference for those who attend youth and high school athletic events. “The Emergency Medical Services for Children (EMSC) program works to ensure proper pediatric care is available on ambulances and in hospital emergency departments nationwide,” said Ian Weston, Co-Director of the EMSC program headquartered in suburban Wash. D.C. “Emergency care providers are integral in ensuring our children get the right care when it counts.” When to call 911 Concussion symptoms can be subtle and may not appear right away, leaving room for mistakes to be made if athletes are not properly monitored when a concussion is suspected. The following are symptoms that require a call for emergency evaluation: •headaches that worsen •seizures •neck pain •very drowsy, can't be awakened •repeated vomiting •increasing confusion or irritability •weakness, numbness in arms and legs •unable to recognize people/places, less responsive than usual For more information see Should we call 911?, signs and symptoms Photo: (L) John Riley (firefighter/paramedic); (R) Travis Anderson (firefighter/EMT) Questions/comments? contact Jean Rickerson at jean@SportsConcussions.org

Alzheimer’s disease and Chronic Traumatic Encephalopathy (CTE) are both “neurodegenerative diseases.” That is, they are brain diseases that result in the progressive destruction of brain cells, eventually leading to cognitive, behavioral, and other impairments. Both diseases also lead to dementia. The distinction between Alzheimer’s and dementia is very often misunderstood, even by many doctors. “Dementia” is a clinical syndrome defined by memory and other cognitive impairments that are severe enough to cause difficulties in social and/or occupational functioning (i.e., reduced independence in functioning). Dementia is not an illness or a disease. Dementia is not a “mild” form of Alzheimer’s. Rather, it is analogous to “fever,” in that it tells you that you are sick, but doesn’t say what is causing the problem. Similarly, dementia means that there is something wrong with the brain’s functioning, but not what is causing it. Several illnesses and diseases can lead to dementia, including Alzheimer’s disease which accounts for approximately 75% of all cases of dementia. However, several other neurodegenerative diseases result in dementia, including CTE. Alzheimer’s and CTE are distinct diseases. Both Alzheimer’s and CTE can only be accurately diagnosed postmortem through a neuropathological examination of the brain. There have been several new scientific breakthroughs over the past few years that now allow doctors and scientists to be much more accurate in diagnosing Alzheimer’s during life. However, at this time, there is no method of diagnosing CTE during life, although our group at the Boston University Center for the Study of Traumatic Encephalopathy (CSTE) recently received a grant from the National Institutes of Health to begin developing these types of tests. One of the major differences between Alzheimer’s and CTE involves what causes each of the diseases. There is no known specific risk factor that leads to Alzheimer’s. For CTE, however, it is believed that repetitive brain trauma (including concussions and subconcussive blows to the head) is a necessary, but not sufficient risk factor. That is, everyone that has been found to have CTE in postmortem examination has had a history of repetitive brain trauma, including athletes (e.g., football and hockey players, boxers and wrestlers), as well as others, such as combat military personnel, developmentally disabled individuals who repeatedly bang their heads, and victims of domestic abuse. Boxers and football players (especially lineman) appear to be the most likely to get the disease because of the repetitive brain trauma exposure. But, it is important to note that not everyone with a history of repetitive brain trauma will develop CTE. Our center is currently conducting research into the other potential additive risk factors, such as genetics, age of initial brain trauma exposure, frequency and overall duration of exposure, etc. This research will hopefully lead us to understand why one person gets the disease and another person does not. This line of investigation, along with our new study to develop methods of diagnosing CTE during life, will eventually lead to effective treatments and prevention strategies. Robert A.

Q: What would you tell athletes about concussions? The NFL is in a state of evolution and recent changes will only make it safer for younger athletes. The league and the NFLPA (National Football League Players’ Association) have made huge strides to address the concussion issue, while maintaining the excitement of the game for both fans and players. It’s important that all athletes remember that you only get one brain and as we learn more about the long-term and adverse effects of contact sports and repetitive head injury, we know that smaller hits over the course of a career- even a high school career- can accumulate. Learn to recognize the symptoms of head trauma. You can have headaches or you might be slightly dizzy …these are all bearable and many athletes mask these symptoms by taking a Tylenol and then they go out and play again. But a concussion is not an ankle or shoulder injury…later in life you can have surgery on that ankle or have knee replacement surgery but you only get one brain. You can’t get a brain replacement. If you mask head trauma you can be risking increased problems in the future for Alzheimer’s or dementia. Head trauma has to be looked at very differently. Yes, in a way it’s a body part like a shoulder, but your brain must be treated very differently. You can ice and elevate an ankle but can’t do that with your brain. Real damage may show up later in life …and it’s not just football, it can happen in any sport. We used to look at toughness and playing through injuries as a badge of honor. That you were tough both mentally and physically and that continuing to play while hurt brought you the respect of your peers. But we need to change the culture now, and that starts with you. You need to believe that it’s OK to miss a game or a week or longer. If you do have to sit out, it means you were playing hard and you took one for the team. You shouldn’t feel ashamed. And if you care about your friends and your teammates, keep them from harm. If you see a friend of yours doing something to hurt themselves, like playing with a concussion, step up and help them. You’re doing them a huge injustice by allowing them to continue to play. You are your brother’s keeper. Become a hero in their life and help them realize what they probably know deep down inside anyway. Someday they’ll look back and know what you did for them, and they’ll respect you more, later in their lives. Be a leader and help change the game. Help create a new norm.

Pop Warner, the nation's largest youth football organization announced Tuesday it is taking steps to eliminate hits to the head and reduce the number of concussions suffered by players. Chairman of the Pop Warner medical advisory board, Dr. Julian Bailes said, "The impact of head-to-head contact causes the most severe concussions, so we felt it was imperative that Pop Warner take a proactive approach and limit contact in practices. We're trying to take away all at once the head-to-head contact in practice." Pop Warner is the nation's oldest and largest youth football, cheerleading and dance program, with over 400,000 members ranging in age from 5-14. Starting in August many teams practice nine hours a week until Labor Day when most are then shortened to six hours. Research has shown that some of the hardest hits and many concussions occur during practice, not games. New rules prohibit head-to-head hits and limit contact in practices to 40 minutes a day. Full-speed head-on blocking and tackling drills where players line up more than three feet apart are no longer allowed. In April 2012, veteran journalist and former Dateline co-anchor, Stone Phillips produced a report entitled, "Hard Hits, Hard Numbers," detailing a Virginia Tech study on head impacts in youth football. Accelerometers placed inside 7- and 8-year-old players' helmets recorded hits from 15g-100g, surprising researchers. Previously, many believed that players that age did not have the speed or strength to deliver hits of those magnitudes. Over 4 million sports- and recreation-related concussions occur each year in the United States and more than half of those are suffered as a result of football, reported NBC News.

Common sense has led many to believe that youth football players can't possibly sustain high-impacts like their adult counterparts. But veteran correspondent Stone Phillips' report "Hard Hits, Hard Numbers," features researchers at Virginia Tech (VT) who recently turned that theory upside down when they analyzed impact data from the helmets of 7- and 8-year old players in Montgomery County, Virginia. Accelerometers placed inside seven helmets wirelessly transmitted data to scientists on the sideline for a season's worth of practices and games, with surprising results. The bottom line? Maybe it's time to take another look at practices, drills, and helmet design to minimize the forces absorbed during an average season. Regardless of the significance of the impact, none of the players sustained concussions during the season. Therein lies an enduring mystery, why small impacts can cause concussions in some players while others walk away from big hits. The force of acceleration is often measured in g. Fighter pilots may "pull" 9g in an F-16, a sneeze may register 3g. They're part of everyday life. But because of the heightened interest in sports-related concussions, researchers are looking at a multitude of ways to reduce brain impacts for everyone from adults to youth. But first, they had to identify if there was even an issue at all. Worth a look The VT study was the first of its kind to measure the impacts sustained during youth football. Having worked for nine years recording over 150,000 hits with the helmet impact system at the university, researchers turned their attention to an area youth league. The forces averaged about 15g, meaning half of the hits measured below that level, the other half above. In one case, well above. One hit measured 100g, a big hit by college standards. Most of the more forceful impacts came during practice. Highlights from PBS NewsHour include: - reseachers believe 98g or above is a red flag for a possible concussion - a total 753 impacts were recorded - average player sustained 107 impacts in one season; high school players average about 500; college players sustain about 1,000/season - there were 38 impacts of 40g or greater; almost every one occurred during practice - six impacts measured over 80g the lower range VT researchers consider to be the risk of concussion - youth football players lack strong neck and chest muscles of older players to maintain head stability - 50, 60, 70g loads were surprising - location of impact is important as are individual differences and tolerances - there is more helmet-to-helmet contact in youth football than occurs in older players; most impacts occurred to the front of the helmet - more head-to-ground impacts found at college level Changes afoot Researchers concluded that addressing changes in practice would likely reduce the number of impacts per season, an important factor in any youth sport. Less contact drills, fewer contact practices and other modifications would be beneficial, particularly as the effects of sub-concussive hits, impacts that may cause changes in the brain without causing symptoms, continue to be studied.

Shepherdstown, W.V. — Senator Jay Rockefeller convened a roundtable discussion at Shepherd University's Wellness Center on Friday with medical experts, sports professionals, coaches, and parents to help raise awareness of many of the causes and impacts of concussions and head injuries in young athletes. He also highlighted problems with the marketing of some sports safety equipment which claim to prevent concussions among athletes. “We all have a responsibility to make sure that kids who play sports are as safe as they can be,” said Rockefeller. “Much of the conversation about concussions has focused on professional athletes, but it affects so many children on the field, court, mat, or track. Last October, I chaired a Senate hearing to help raise awareness about concussions in youth sports, but our job is not done. We need to make sure that everyone in West Virginia knows how to reduce the number of concussions, since they can have long-term consequences for our children’s health. “Playing sports doesn’t just make kids stronger and healthier. It also teaches them important values – hard work, leadership, and the importance of working together. I encourage everyone here today to tell their friends and family about how to better protect student athletes so that we can reduce injuries, increase awareness about some false marketing of sports equipment, and make sure our kids stay healthy.” The roundtable provided an opportunity to discuss the dangers of concussions for young athletes, the steps that parents and coaches should take to protect young athletes from concussions, and the limitations of sports equipment in preventing concussions. The discussion included medical experts from West Virginia to discuss the dangers and frequency of concussions for young athletes, sports officials from the state to explain the steps currently being taken to protect young athletes from concussions on the field, and representatives from the Consumer Product Safety Commission and the Federal Trade Commission to discuss the role of the federal government in creating safety standards for products and investigating marketing claims made by manufacturers. On October 19, Rockefeller, Chairman of the Senate Committee on Commerce, Science, and Transportation, held a hearing on concussions and the marketing of sports equipment to increase awareness of both the dangers of concussions for athletes participating in sports at all levels and the misleading marketing claims about concussions made by sports equipment manufacturers. Rockefeller convened the hearing because much of the discussion on concussions had largely focused on the dangers of concussions at the professional level, even though a significant percentage of those suffering concussions are children and high school students participating in sports, especially contact sports like soccer, football, and hockey.

Bronx, NY — Patients vary widely in their response to concussion, but scientists haven’t understood why. Now, using a new technique for analyzing data from brain imaging studies, researchers at Albert Einstein College of Medicine of Yeshiva University andMontefiore Medical Center have found that concussion victims have unique spatial patterns of brain abnormalities that change over time. The new technique could eventually help in assessing concussion patients, predicting which head injuries are likely to have long-lasting neurological consequences, and evaluating the effectiveness of treatments, according to lead author Michael L. Lipton, M.D., Ph.D., associate director of the Gruss Magnetic Resonance Research Center at Einstein and medical director of magnetic resonance imaging (MRI) services at Montefiore. The findings are published today in the online edition of Brain Imaging and Behavior. The Centers for Disease Control and Prevention estimates that more than one million Americans sustain a concussion (also known as mild traumatic brain injury, or mTBI) each year. Concussions in adults result mainly from motor vehicle accidents or falls. At least 300,000 adults and children are affected by sports-related concussions each year. While most people recover from concussions with no lasting ill effects, as many as 30 percent suffer permanent impairment – undergoing a personality change or being unable to plan an event. A 2003 federal study called concussions “a serious public health problem” that costs the U.S. an estimated $80 billion a year. Previous imaging studies found differences between the brains of people who have suffered concussions and normal individuals. But those studies couldn’t assess whether concussion victims differ from one another. “In fact, most researchers have assumed that all people with concussions have abnormalities in the same brain regions,” said Dr. Lipton, who is also associate professor of radiology, ofpsychiatry and behavioral sciences, and in the Dominick P. Purpura Department of Neuroscience at Einstein. “But that doesn’t make sense, since it is more likely that different areas would be affected in each person because of differences in anatomy, vulnerability to injury and mechanism of injury.” In the current study, the Einstein researchers used a recently developed MRI technique called diffusion tensor imaging (DTI) on 34 consecutive patients (19 women and 15 men aged 19 to 64) diagnosed with mTBI at Montefiore in the Bronx and on 30 healthy controls. The patients were imaged within two weeks of injury and again three and six months afterward. The imaging data were then analyzed using a new software tool called Enhanced Z-score Microstructural Assessment Pathology (EZ-MAP), which allows researchers for the first time to examine microstructural abnormalities across the entire brain of individual patients. EZ-MAP was developed by Dr. Lipton and his colleagues at Einstein. DTI detects subtle damage to the brain by measuring the direction of diffusion of water in white matter. The same technology was used by Dr. Lipton and his team in widely publicized research on more than 30 amateur soccer players who had all played the sport since childhood. They found that frequent headers showed brain injury similar to that seen in patients with concussion. The uniformity of diffusion direction – an indicator of whether tissue has maintained its microstructural integrity – is measured on a zero-to-one scale called fractional anisotropy (FA). In the latest study, areas of abnormally low FA (reflecting abnormal brain regions) were observed in concussion patients but not in controls. Each concussion patient had a unique spatial pattern of low FA that evolved over the study period. Surprisingly, each patient also had a unique, evolving pattern of abnormally high FA distinct from the areas of low FA. “We found widespread high FA at every time point, all the way out to six months and even in patients more than one year out from their injury.” said Dr. Lipton. “We suspect that high FA represents a response to the injury. In other words, the brain may be trying to compensate for the injury by developing and enhancing other neural connections. This is a new and unexpected finding.” At present, diagnosis of concussions is based mainly on the nature of the patient’s accident and the presence of symptoms including headache, dizziness and behavioral abnormalities. DTI, combined with EZ-MAP analysis, might offer a more objective tool for diagnosing concussion injuries and for predicting which patients will have persistent and progressive symptoms.
