As female participation in sports grows rapidly, there is a popular notion that there are gender-related differences in athletes' responses to sports-related concussion, and prior research has supported these gender discrepancies. However, a Vanderbilt University Medical Center study, conducted to review symptoms and neurocognitive findings in male and female high school soccer players, shows no gender-related differences. "There has been good data that suggests girls score worse on neurocognitive testing following a sports-related concussion. Our hypothesis was that a tightly-controlled study would replicate what others have shown previously," said Scott Zuckerman, M.D., a neurosurgery resident who conducted the study with colleagues at the Vanderbilt Sports Concussion Center. The researchers selected 40 male and 40 female concussed patients who were matched, as closely as possible, for age, medical/psychiatric history, years of education, lack of special education assistance, history of psychiatric treatment, number of prior concussions, timing of pre- and post-concussion testing, and sport (all engaged in soccer). This is the first study to control for type of sport played when looking a gender differences, Zuckerman said. "Prior studies have used mixed groups of athletes from a variety of sports. We suspected that since concussions vary from sport to sport (i.e., helmets vs. none, varying biomechanical forces, etc.), if the variable of sport was controlled, gender differences might disappear." The only significant gender-related difference they could identify was that female soccer players reported a greater number of symptoms post-concussion. There were no significant differences in post-concussion neurocognitive scores. "We were somewhat surprised and were not sure what to expect in such a tightly controlled population," Zuckerman said. "Our hypothesis was that females would experience greater levels of acute, post-concussive, neurocognitive impairment than males, fitting with what most of the prior literature says, but we found virtually no difference between males and females." Zuckerman said this is a significant finding for the treatment of sports-related concussion. "When we see any child after concussion, we don't want to make snap decisions based on gender. Gender may not be as big a modifying factor as previously thought." This study is the first from V-SCoRe, or Vanderbilt Sports Concussion Research. Collaborators include Allen Sills, M.D., Gary Solomon, Ph.D., Andrew Gregory, M.D., Alex Diamond, D.O., and Jonathan Forbes, M.D., and medical students Mitchell Odom and Young Lee. "This effort is just getting off the ground, and we're investigating many more modifying factors in concussion, including age, sleep, symptoms, prior history of attention deficit disorder," Zuckerman said. "Our goal is to create new knowledge in this area and help providers better understand when a young athlete can return to play safely."

NFL Hall of Famer "Iron Mike" Webster's life ended in 2002 when he suffered a heart attack at age 50. Four Super Bowl rings, nine Pro Bowls, and voted to the NFL's all-time team in 2000, the driven, ultra-competitive Steelers' center drifted into a life of drug use, homelessness, and enormous suffering after retiring in 1988. In 2005, his son Garrett told ESPN that the only way his father could get to sleep was to taser himself into unconsciousness. Former teammates and friends offered assistance over the years but it wasn't enough. After Webster's death, forensic neuropathologist Dr. Bennet Omalu was determined to find neurological reasons for his cognitive decline. Seventeen years in the NFL at a time when safety precautions and concussion awareness were both minimal had resulted in thousands of impacts to his head. Though his brain looked normal at autopsy, Omalu pressed on until he found the abnormalities that we now call Chronic Traumatic Encephalopathy, or CTE. CTE and Alzheimer's CTE and Alzheimer's 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 Alzheimer’s and CTE can only be accurately diagnosed postmortem through a neuropathological examination of the brain and their progression has remained elusive. But clues about how Alzheimer's spreads from neuron to neuron are now emerging. Whether the same process of progression applies to CTE is currently unclear. Photo: Alzheimer's infects from neuron to neuron The inexorable spread of Alzheimer’s disease through the brain leaves dead neurons and forgotten thoughts in its wake. Researchers at Linköping University in Sweden are the first to show how toxic proteins are transferred from neuron to neuron. Through experiments on stained neurons, the research team – under the leadership of Martin Hallbeck, associate professor of Pathology – has been able to depict the process of neurons being invaded by diseased proteins that are then passed on to nearby cells. “The spread of Alzheimer’s, which can be studied in the brains of diseased patients, always follows the same pattern. But until now how and why this happens has not been understood,” says Hallbeck, who along with his research group has now published their results in The Journal of Neuroscience. The illness starts in the entorhinal cortex – a part of the cerebral cortex, and then spreads to the hippocampus. Both of these areas are important for memory. Gradually, pathological changes take place in more and more areas of the brain, while the patient becomes even sicker. Two proteins have been identified in connection with Alzheimer’s: beta amyloid and tau. Normally tau is found in the axons – the outgrowths that connect between neurons – where it has a stabilising function, while beta amyloid seems to have a role in the synapses where the neurons transfer signal substances to each other. But in Alzheimer’s patients, something happens with these proteins; autopsies reveal abnormal accumulations of both. Why they become abnormal is still unknown, but what is known is that it’s not the large accumulations, or plaques, that damage the neurons. Instead, smaller groups of beta amyloid – called oligomeres – seem to be the toxic form that gradually destroy the neurons and shrink the brain. “We wanted to investigate whether these oligomeres can spread from neuron to neuron, something many researchers tried earlier but didn’t succeed,” Hallbeck says. The study was inaugurated with an experiment on neuron cultures, where researchers injected oligomeres stained with a phosphorescent red substance called TMR using a very thin needle. The next day the neighbouring, connected neurons were also red, which showed that the oligomeres had spread. To test whether a sick neuron can “infect” others, they conducted a round of experiments with mature human neurons stained green and mixed with others that were red after having taken up stained oligomeres. After a day, approximately half of the green cells had been in contact with a few of the red ones. After two more days, the axons had lost their shape and organelles in the cell nucleus had started to leak. “Gradually more and more of the green cells became sick. Those that hadn’t taken up the oligomeres, on the other hand, weren’t affected,” Hallbeck says. The study is a breakthrough in understanding Alzheimer’s and its progress. If a way of stopping the transfer can be found, it could lead to a more effective inhibitor against the disease.

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.

What does it mean to have a head concussion? Much has been written in recent years about the short- and long-term consequences of concussions sustained in sports, combat, and accidents. However, there appear to be no steadfast rules guiding the definition of concussion: the characteristics associated with this type of traumatic head injury have shifted over time and across medical disciplines. Within the context of a larger longitudinal investigation of the biomechanical factors in play that correlate with concussions in collegiate helmeted contact sports, researchers in New England and Virginia used data they obtained to investigate which signs, symptoms, and clinical histories were used by athletic trainers to define concussion in individual players. The investigators found that a heterogeneous collection of acute clinical characteristics currently exists for those events diagnosed as concussion in college athletes engaged in contact sports. Together with her colleagues, Dr. Duhaime, Director of Pediatric Neurosurgery and of Neurotrauma and Intensive Care in the Neurosurgical Service of Massachusetts General Hospital, examined concussions diagnosed in athletes participating in helmeted contact sports (football and ice hockey) at three universities: Dartmouth, Brown, and Virginia Tech. Both male and female athletes participated in the study. The students' helmets were outfitted with Head Impact Telemetry (HIT) System™ technology to record and measure peak linear and angular acceleration of impacts. The helmets were worn during practice sessions and games throughout two to four seasons. The investigators did not attempt to influence how trainers and team medical personnel defined concussion operationally, but instead relied on the clinical characteristics deemed indicative of concussion by the universities' athletic departments. More than 486,000 head impacts were recorded in 450 athletes, and concussion was diagnosed in 44 of these athletes (48 concussions) by team medical staff. Unlike concussions more often diagnosed in emergency departments, where a single, identified contact event leads to a loss of consciousness or other clear alteration in consciousness, most diagnoses in this sports setting were based on self-reports by athletes, and only a few were based on changes in athletes' clinical conditions that were observed by others. Thirty-one concussions could be directly associated with a specific impact, whereas a relationship with a specific impact could not be verified in the other cases of concussion. Only half of the athletes noted symptoms immediately after a contact event; in many athletes, the onset of symptoms was delayed. The most common reported symptoms were mental clouding, headache, and dizziness; only one case involved a loss of consciousness. The diagnosis of concussion by trainers often occurred in an even more delayed fashion: the diagnosis was made immediately after the event in 6 cases and at a later time in the other cases (median 17 hours postinjury). In general, the mean peak linear and angular accelerations for specific impact events that could be directly linked to concussions tended be in the high percentiles for the sports examined; however, there was considerable variability in the ranges of these measurements (mean peak linear acceleration 86.1 ± 42.6 g [range 16.5.9 g], mean peak angular acceleration 3620 ± 2,166 rads/sec2 [range 183,589 rads/sec2]). The variety of signs and symptoms, the imprecise timing of symptom appearance and relationship to a specific contact event, the lack of externally observed findings, and the broad ranges of the linear and angular accelerations of the impacts that coalesce in a diagnosis of concussion in college sports make it difficult to identify predictors of acute, intermediate, and long-term risks of adverse consequences resulting from sports-related head impacts. By describing the heterogeneity inherent in diagnoses of concussion as a "concussion spectrum," the authors point out the need for renewed efforts to determine which factors -- clinical, mechanical, genetic, or others -- influence outcomes in patients with single as well as repeated head impacts. The authors point out that while a clinical diagnosis is important to protect players from additional and potentially more serious consequences, it is also possible that athletes who do not receive the diagnosis of "concussion" may be at similar risk. Likewise, it is possible that some players who receive a diagnosis of concussion do not fall into a high-risk category for specific consequences. The authors note that there is still much to be learned, and that the terminology in use can sometimes oversimplify a more complex set of processes that still need to be teased apart. In their response to an accompanying editorial, they state, "By carefully characterizing exactly what we are talking about and by continued investigation, which will take more time ... , neurosurgeons and others will be best positioned to offer effective treatments and to advocate knowledgeably for appropriate injury-prevention strategies."

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.

USA Football and Steelers' staff had a host of recommendations for increasing concussion safety for area youth football players at Saturday's coaches clinic at the UPMC Sports Complex in Pittsburgh. Know the signs and symptoms. Teach proper tackling technique. Limit full-contact padded practices. "The whole idea is to help our kids play the game of football the right way," Steelers president Art Rooney II said to nearly 100 youth coaches, according to the Pittsburgh-Post Gazette. The Centers for Disease Control and Prevention estimates there are 3.8 million sports and recreation-related concussion annually. Most injuries are sustained while bicycling, followed by organized contact sports such as football and ice hockey and playground mishaps. Last month, data were released on the forces incurred over the course of a full season by 7- and 8-year-old football players in northern Virginia. The magnitude of the hits were measured using accelerometers placed inside several helmets. Many were comparable to forces felt in a pillow fight, but some were on par with those sustained by high school or collegiate players. The higher magnitude forces typically occurred during practices, not games. Ed Passino, Northeast regional manager for USA Football urged coaches to limit full-contact practices. "One thing that we're teaching throughout the country is that you don't have to hit every day in practice," Passino said. "It's not 1950 anymore. Update the way you handle practice. "Maybe you only hit one day a week, you can still conduct form tackling without full-on collisions." The eight Ivy League presidents, two of whom are medical doctors, limited contact practices for their football teams last summer, allowing fewer than the NCAA.

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.

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.
