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.

It is not yet known why girls suffer concussions at a higher rate than boys. The most prevalent theories range from lesser neck and upper body strength, to better reporting among females, to hormonal differences. Researchers at Emory University in Atlanta are currently in the third phase of a clinical trial designed to determine if the hormone progesterone, normally associated with female reproductive processes, can protect damaged neurons. Administered within four hours of the injury and lasting for three days, results of the treatment have been positive so far. Although catastrophic injuries in sports are rare, the question regarding applicability of a related treatment for concussion remains open. Pilot study highlighted efficacy Every 15 seconds, someone in the United States sustains a significant traumatic brain injury. Approximately 2 million adults and children in the United States suffer from traumatic brain injuries each year - leading to 50,000 deaths and 80,000 new cases of long-term disability, according to the Centers for Disease Control and Prevention. Despite the enormity of the problem, scientists have failed to identify effective medications to improve outcomes following a traumatic brain injury. Emory researchers, however, concluded in an earlier pilot clinical trial that giving progesterone to trauma victims shortly following brain injury appears to be safe and may reduce the risk of death and long-term disability. Their previous three-year study, called ProTECT I (Progesterone for Traumatic brain injury--Experimental Clinical Treatment), enrolled 100 participants at Grady Memorial Hospital. It was designed to evaluate whether progesterone can be administered intravenously in a safe and reliable way. "We found evidence that progesterone is not only safe for use in patients suffering from traumatic brain injuries," says Wright. "We also found a 50 percent reduction in mortality in those patients treated with progesterone. Even though this was a small pilot study, we found signs that progesterone improved functional outcomes and reduced disability in patients with moderate brain injury. "By expanding our test sites to 17 major trauma centers across 15 states and enrolling more than 1,000 patients, we hope to confirm these preliminary findings and determine if progesterone benefits victims of acute traumatic brain injury," says Wright. Progesterone common in males and females Progesterone is naturally present in small but measurable amounts in the brains of males and females. Human brain tissue is loaded with progesterone receptors. Laboratory studies suggest that progesterone is critical for the normal development of neurons in the brain and exerts protective effects on damaged brain tissue. Donald G. Stein, PhD, Asa G. Candler Professor of Emergency Medicine, Emory School of Medicine, and director of Emory's Department of Emergency Medicine Brain Research Laboratory, pioneered discoveries regarding the effect of progesterone following traumatic brain injury - first discovering the neuro-protective properties of progesterone in the laboratory more than 25 years ago. "The results that we are now seeing, and hope to continue validating, are an incredible and gratifying reward for more than 25 years of concentrated research," says Stein. "My work first started when I began to notice evidence that women tended to respond to treatment and recover better than men after suffering from brain injury and stroke. Many people do not realize that it's not just a female hormone; both men and women produce progesterone directly in the brain, as well as other tissue. "Ultimately, we learned that progesterone basically does in brain injuries what it also does during fetal development - protect cells and tissue," says Stein. "To now witness the translation of this laboratory research into a treatment that may have life-saving benefits is breathtaking."

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.

KANSAS CITY, Mo. -- The National Operating Committee on Standards for Athletic Equipment (NOCSAE) issued a warning to athletes and parents of athletes to thoroughly understand the extent of protection provided by – or not provided by – athletic equipment worn while playing sports. This warning follows claims made by several companies that products such as head bands, supplements or mouth guards reduce the incident of concussion. NOCSAE issued the warning at the onset of its summer meeting held this year in Kansas City. NOCSAE is an independent organization with the dual purpose of setting standards for the performance of athletic equipment and funding research necessary to advance the science of sports. Through NOCSAE's independent process, physicians, academic researchers, coaches, trainers and manufacturers come together to establish standards based on accepted science and reliable data. "Parents, athletes and coaches are becoming more informed about concussions, and this increased awareness is vitally important to advancing athlete safety. But it also creates a demand for quick solutions. Unfortunately there are quick solutions offered for sale which have neither scientific nor medical support that validate their claims to prevent or reduce concussions," said Mike Oliver, NOCSAE executive director. "Any device or supplement promoted as being able to prevent, diagnose or cure a concussion must be supported by scientific data and peer-reviewed research. Currently there is no definitive scientific research linking mouth guards, head bands, supplements or other specialty products to a reduction in concussion risk or severity. For companies to suggest otherwise misleads athletes, parents and coaches into a dangerous false sense of protection against concussion. NOCSAE warns athletes and parents of athletes to get the facts about sports equipment and concussion protection and not rely solely on marketing and promotional materials when making equipment decisions." NOCSAE does not maintain any standards for such products, and, therefore, no such products can be claimed as meeting the NOCSAE standards. While protective equipment certified to the NOCSAE standard play an incredibly important role in protecting athletes on the field of play, they should be not the primary approach to protecting against concussion. Learning to avoid unnecessary head impacts, reporting concussion symptoms to a coach or parent and following trained medical management decisions about when a concussed athlete can return to play are far more likely to prevent a concussion or reduce the chance of chronic problems that may be related to untreated concussions.

The brain appears to be wired more like the checkerboard streets of New York City than the curvy lanes of Columbia, Md., suggests a new brain imaging study. The most detailed images, to date, reveal a pervasive 3D grid structure with no diagonals, say scientists funded by the National Institutes of Health. “Far from being just a tangle of wires, the brain’s connections turn out to be more like ribbon cables -- folding 2D sheets of parallel neuronal fibers that cross paths at right angles, like the warp and weft of a fabric,” explained Van Wedeen, M.D., of Massachusetts General Hospital (MGH), A.A. Martinos Center for Biomedical Imaging and the Harvard Medical School. “This grid structure is continuous and consistent at all scales and across humans and other primate species." Wedeen and colleagues report new evidence of the brain’s elegant simplicity March 30, 2012 in the journal Science. The study was funded, in part, by the NIH’s National Institute of Mental Health (NIMH), the Human Connectome Project of the NIH Blueprint for Neuroscience Research, and other NIH components. “Getting a high resolution wiring diagram of our brains is a landmark in human neuroanatomy,” said NIMH Director Thomas R. Insel, M.D. “This new technology may reveal individual differences in brain connections that could aid diagnosis and treatment of brain disorders.” Knowledge gained from the study helped shape design specifications for the most powerful brain scanner of its kind, which was installed at MGH’s Martinos Center last fall. The new Connectom diffusion magnetic resonance imaging (MRI) scanner can visualize the networks of crisscrossing fibers – by which different parts of the brain communicate with each other – in 10-fold higher detail than conventional scanners, said Wedeen. “This one-of-a-kind instrument is bringing into sharper focus an astonishingly simple architecture that makes sense in light of how the brain grows,” he explained. “The wiring of the mature brain appears to mirror three primal pathways established in embryonic development.” As the brain gets wired up in early development, its connections form along perpendicular pathways, running horizontally, vertically and transversely. This grid structure appears to guide connectivity like lane markers on a highway, which would limit options for growing nerve fibers to change direction during development. If they can turn in just four directions: left, right, up or down, this may enforce a more efficient, orderly way for the fibers to find their proper connections – and for the structure to adapt through evolution, suggest the researchers. Obtaining detailed images of these pathways in human brain has long eluded researchers, in part, because the human cortex, or outer mantle, develops many folds, nooks and crannies that obscure the structure of its connections. Although studies using chemical tracers in neural tracts of animal brains yielded hints of a grid structure, such invasive techniques could not be used in humans. Wedeen’s team is part of a Human Connectome Project Harvard/MGH-UCLA consortiumExternal Link: Please review our disclaimer. that is optimizing MRI technology to more accurately to image the pathways. In diffusion imaging, the scanner detects movement of water inside the fibers to reveal their locations. A high resolution technique called diffusion spectrum imaging (DSI) makes it possible to see the different orientations of multiple fibers that cross at a single location – the key to seeing the grid structure. In the current study, researchers performed DSI scans on postmortem brains of four types of monkeys – rhesus, owl, marmoset and galago – and in living humans. They saw the same 2D sheet structure containing parallel fibers crossing paths everywhere in all of the brains – even in local path neighborhoods. The grid structure of cortex pathways was continuous with those of lower brain structures, including memory and emotion centers. The more complex human and rhesus brains showed more differentiation between pathways than simpler species. Among immediate implications, the findings suggest a simplifying framework for understanding the brain’s structure, pathways and connectivity. The technology used in the current study was able to see only about 25 percent of the grid structure in human brain. It was only apparent in large central circuitry, not in outlying areas where the folding obscures it. But lessons learned were incorporated into the design of the newly installed Connectom scanner, which can see 75 percent of it, according to Wedeen. Much as a telescope with a larger mirror or lens provides a clearer image, the new scanner markedly boosts resolving power by magnifying magnetic fields with magnetically stronger copper coils, called gradients. Gradients make it possible to vary the magnetic field and get a precise fix on locations in the brain. The Connectom scanner’s gradients are seven times stronger than those of conventional scanners. Scans that would have previously taken hours – and, thus would have been impractical with living human subjects – can now be performed in minutes. “Before, we had just driving directions. Now, we have a map showing how all the highways and byways are interconnected,” said Wedeen. “Brain wiring is not like the wiring in your basement, where it just needs to connect the right endpoints. Rather, the grid is the language of the brain and wiring and re-wiring work by modifying it.” Curvature in this DSI image of a whole human brain turns out to be folding of 2D sheets of parallel neuronal fibers that cross paths at right angles. This picture came from the new Connectom scanner.Source: Van Wedeen, M.D., Martinos Center and Dept. of Radiology, Massachusetts General Hospital and Harvard University Medical School Reference Wedeen VJ, Rosene DL, Ruopeng W, Guangping D, Mortazavi F, Hagmann P, Kass JH, Tseng W-YI.

Starting in 2012, helmet reconditioners will no longer accept helmets 10 years or older. Leagues that have depended on reconditioning their helmets every year and cannot afford replacement gear will be most affected. Although helmets do not prevent concussions, most experts agree that newer ones are preferable to used, and an older, unreconditioned helmet might increase the risk of injury. Many leagues ask their booster clubs for assistance with fundraising as this issue has now reached a critical phase. Limited grants for replacement helmets by leading manufacturers are now available for eligible youth leagues in several areas around the country. Applications are now being accepted for youth football programs seeking to replace their league's helmets before the start of the 2012 season. The Centers for Disease Control and Prevention, USA Football and partnering organizations have introduced a helmet replacement program for youth in underserved communities. It is estimated the program will provide almost 13,000 new helmets to athletes in low-income communities beginning in July 2012. To qualify a league must meet the following criteria: - Operate a youth football league (no middle or high school programs) - Live in one of the following areas: Cleveland, New Orleans, New York, or the San Francisco Bay area - Serve an economically disadvantaged area The application process requires registration at USA Football, the governing body for youth football under the NFL. The application is accessible only after viewing a concussion awareness video and pledging to utilize USA Football's resources to educate members of your league before the 2012 season. A visit from an official to verify the ages and number of helmets exceeding 10 years of age in your inventory will occur by mid-June, with new helmets arriving prior to the beginning of the 2012 season. Participating helmet manufacturers include Rawlings, Xenith, Riddell and Schutt. Questions/comments? contact Jean Rickerson at jean@SportsConcussions.org

Researchers at Nationwide Children's Hospital in Columbus, Ohio, found that of the 14,635 high-school sports injuries reported during the 2008-2010 school year, 13% were concussions. The majority of them were uncomplicated, in fact, 40% of the students who suffered concussions saw their symptoms disappear within three days. Most returned to play within three weeks, but a significant number -- about 25% -- returned to play the same day they were injured, a situation many state concussion laws are designed to address. "This improper practice was widespread," noted researchers Mallika Marar, Natalie McIlvain, Sarah Fields and R. Dawn Comstock, who found it in 12 of the 20 sports they studied. "This clearly violates the consensus statement on sports-related concussion, which recommends that no adolescent athlete who sustains a concussion should return to play on the day of the injury,"reported WPTV.com. Other findings included: Most common symptoms: headache (94.2%), dizziness (75.6%) and difficulty concentrating (54.8%) More than one: Eleven percent had suffered concussions before, highest rate of recurrence was boys' wrestling (20%) Most by number: football (47%) followed by girls' soccer (8.2%) Most common practices/games: games; exception was cheerleading, participants were 10x more likely to be hurt during practice Most by gender: boys; although concussions in girls' sports represented a higher number of overall injuries Most common occurrence: athlete-to-athlete contact; girls were more likely to suffer a concussion from striking the ground or being struck by another players' piece of equipment such as a hockey stick The study was published in the January edition of the American Journal of Sports Medicine.

PITTSBURGH – The unpredictable nature of concussions is one of the most frustrating factors to the millions of sufferers each year, but early neurological indicators and symptoms can predict a protracted healing time in certain cases, according to specialists at UPMC and the University of Pittsburgh School of Medicine. “It’s a highly variable injury with a variety of outcomes,” said Michael “Micky” Collins, Ph.D., director of the UPMC Sports Medicine Concussion Program and co-investigator of the Pitt/UPMC study published in the February issue of Neurosurgery. “We see some patients who take a day or two to recover, and some who take a year or longer to recover. If clinicians had a way of determining within two days of injury who’s going to take a month or longer to recover, that’s a very important piece of information to have. It’s a game-changer.” The study, one of the first to examine concussion prognoses, showed that specific neurocognitive “cut-off” scores derived from ImPACT™ (Immediate Post-concussion Assessment and Cognitive Testing) improved clinicians’ ability to predict which sports-related concussions could take longer –- as much as five times longer -- to rehabilitate than others. They found, in as many as 85 percent of the cases, the scores could warn athletes, parents, coaches, schools, teams and health professionals when a concussion is likely to take on average a month to heal. Such an objective prognosis could help clinicians to better prepare a treatment plan, arrange academic accommodations for students and set tangible expectations for return to play and school, Dr. Collins said. The study reviewed 108 high-school football players who were given ImPACT tests within a median of two days after their concussions. Fifty boys experienced a recovery lasting, on average, 33 days before returning to play, and those longer rehabilitations could be forecast by specific “cut-off” scores in ImPACT Visual and Processing Speed testing. Migraine and cognitive symptoms also appeared to have predictive power. Study participants who scored above the threshold levels recovered within a median of seven days. “We’ve established statistical ‘cut-offs’ that indicate people who take a month or longer to recover,” Dr. Collins said. “Eighty percent of concussed people recover inside of three weeks. This prognostic information allows us to develop a risk profile of athletes who don’t recover well from this injury. Other study authors include Brian Lau, B.S., from the Pitt School of Medicine, and Mark Lovell, Ph.D., the Concussion Program’s founding director who retired from UPMC last summer.

Wisconsin governor Scott Walker signed youth concussion legislation into law today at Lambeau Field in Green Bay. Support for the bill came from physicians, student-athletes, the NFL's Green Bay Packers and other organizations. NFL Commissioner Roger Goodell has exhibited an unwavering committment to the adoption of concussion legislation nationwide, starting with the Washington state concussion law named after middle school football player Zackery Lystedt, who was injured during a game in 2006. Like the Lystedt Law, Wisconsin's concussion law calls for the removal of any athlete suspected of having suffered a concussion and requires a player to obtain written medical authorization before resuming activity. The new law also requires the state Department of Public Instruction to work in conjunction with the Wisconsin Interscholastic Athletic Association to develop guidelines and education standards for parents, coaches, and athletes.
