survivors and caregivers. The Concussion Health Summit will also provide opportunities to network through social events and round table discussions.

“Hearing from the diverse panel of experts assembled will afford attendees an opportunity to expand their knowledge and skill base in caring for concussion patients,” said Mark A. Letendre, ATC, Co-Chair of The Concussion Health Summit and Director of Umpire Medical Services for Major League Baseball. “Allowing a hands-on approach as part of the Summit will take thoughts and information shared and turn them into actionable patient care trajectories.”

The Summit will be highlighted by Dr. Kevin Guskiewicz who will serve as Luncheon Keynote Speaker on Saturday, July 29th.  Dr. Guskiewicz is a neuroscientist, nationally recognized expert and leading researcher in the field of sport-related concussions. He became dean of the College of Arts and Sciences at the University of North Carolina at Chapel Hill in January 2016.

Other highlights include but are not limited to:

  • Nationwide Children’s Hospital Speaker –Thomas Pommering, DO, is Division Chief for Sports Medicine and Medical Director for Nationwide Children’s Sports Medicine. He is a Clinical Assistant Professor in the Department of Pediatrics and Family Medicine at The Ohio State University College of Medicine. “The Concussion Health Summit is a great opportunity for medical professionals to learn and begin the process of applying the latest concussion diagnosis and clinical treatment advances supported by vigorous research,” said Pommering. “On behalf of Nationwide Children’s Hospital and Nationwide Children’s Sports Medicine, we are pleased to partner with Concussion Health and offer continued education and discussion on this very important topic.”
  • Baseline/Performance and Rehab/Progression Hands-On Workshops – These 30 minute hands-on workshops mimic clinical settings, providing interactive experiences with experts and attendees. Topics include: Train Above the Neck; Neck Strengthening; Lower Extremity Functional Testing; Vestibular; Vision; Exertion; Sport Specific Training.
  • Cutting-Edge Topics – Treatment of Concussion Starting Day 2; Baseline Testing as a Comprehensive Injury Program; Correlation Between Mild Head Trauma in Elderly Falls and Repeated Visits to the Emergency Department; Treatment Program for PTSD; Latest Non-Traditional Adjunctive Brain Recovery Therapies; Sub-Concussive Head Injuries; Neuropsychological Testing.
  • Continuing Education Credits – The Concussion Health Summit has been approved for 14 EBP Category hours/CEUs for Athletic Trainers and 14 continuing education credit hours for Physical Therapists and Occupational Therapists.

“Traumatic brain injury (TBI) has received notable attention in the literature over many years with a consensus that each individual presents uniquely and recovery requires an intra-disciplinary and customized approach,” said Bridgett Wallace, PT, DPT and Co-Chair of The Concussion Health Summit. “Yet, such ideas towards concussion (a type of TBI) has lagged in both research and clinical application. It is extremely exciting and promising to see experts from a variety of medical specialties sharing their knowledge on the evolving field of concussion management, especially the evolution of concussion as a treatable injury.”

ICHIRF: PFA To Support Concussion in Sport Project

The Concussion Foundation has announced that the PFA (Professional Footballers Association) has donated funds to support the Concussion in Sport study set up by ICHIRF (International Concussion & Head Injury Research Foundation). This project is looking at the long-term effects of concussion in men and women who have competed in impact sports and the support of the PFA will ensure that retired footballers are now included in this study.

Dr Michael Turner, Director of Concussion in Sport, says: “The support of the PFA is a major step forward and will ensure that our research now includes retired footballers. This will broaden the scope of the ICHIRF project and we are extremely grateful to Gordon Taylor and John Bramhall for their confidence in our ground-breaking study”

The ICHIRF project is part of a multi-national collaboration between concussion research centres in Australia, Switzerland and the USA. This independent research seeks to establish whether retired sportsmen and sportswomen have an increased incidence of, or suffer an earlier onset of neuro-degenerative disorders such as Parkinson’s Disease, Alzheimer’s Disease and the condition currently described as chronic traumatic encephalopathy (CTE).

ICHIRF is also looking for control subjects who have never suffered a concussion and further information can be found at www.ichirf.org or by contacting Pippa Theo at the ICHIRF Office, pippa@ichirf.org 0207 935 3015.

How Blows to the Head Cause Numerous Small Swellings Along the Length of Neuronal Axons

Researchers from The Ohio State University have announced they have discovered how blows to the head cause numerous small swellings along the length of neuronal axons. The study, “Polarity of varicosity initiation in central neuron mechanosensation,” which will be published June 12 in The Journal of Cell Biology, observes the swelling process in live cultured neurons and could lead to new ways of limiting the symptoms associated with concussive brain injuries.

Mild traumatic brain injuries, or concussions, cause a variety of temporary symptoms, including headache, nausea, and memory loss. But the effects of concussive impacts on neurons in the brain are poorly understood. One such effect is the development of “axonal varicosities,” small, bead-like swellings that appear along the length of neuronal axons, which are the parts of neurons that transmit electrical and chemical signals to neighboring nerve cells. Similar swellings are seen in the degenerating axons of Alzheimer’s and Parkinson’s patients.

Chen Gu and colleagues at The Ohio State University discovered that they could induce the formation of axonal varicosities in hippocampal neurons grown in the lab by “puffing” them with bursts of liquid from a small pipette. The pressure exerted by these puffs was similar to the forces neurons might experience after a blow to the head.

The axonal varicosities formed rapidly, particularly in younger neurons where they swelled up within 5 seconds of being puffed. A surprise to the researchers was that the varicosities disappeared several minutes after puffing, indicating that they are not a sign of irreversible axon degeneration.

Gu and colleagues could also induce axonal varicosities by repeatedly puffing cultured neurons with shorter bursts of liquid, mimicking the effects of repetitive, subconcussive impacts. Accordingly, the team also saw axonal varicosities in the brains of mice subjected to repeated light blows to the head.

The researchers found that puffing activated a mechanosensitive channel protein called TRPV4, which is enriched in the membrane of neuronal axons and allows calcium ions to enter the cell. Inhibiting this channel blocked the formation of axonal varicosities.

After entering axons through activated TRPV4 channels, calcium ions appear to disrupt the microtubule cytoskeleton by inhibiting a microtubule-stabilizing protein called STOP. This interrupts the transport of cellular materials along axonal microtubules, causing these materials to accumulate at several points along the axon where they may give rise to varicosities.

Older neurons, which are more resistant to the effects of puffing, express lower levels of TRPV4 and higher levels of STOP. “It will be interesting to determine whether these factors make a mature brain more resistant to mild traumatic brain injury than a young brain,” says Gu.

Puffing didn’t induce varicosities along the lengths of dendrites, the parts of neurons that receive chemical signals from neighboring nerve cells. Instead, the researchers found that dendritic, but not axonal, varicosities could be induced by prolonged treatment with glutamate, an excitatory neurotransmitter that is released from damaged axons.

“Taken together, our findings provide novel mechanistic insights into the initial stage of a new type of neuronal plasticity in health and disease,” says Gu, who points out that axonal varicosities have also been observed in healthy brains where neurons may respond to mechanical signals from their environment. “This process may therefore play a key role in neural development and central nervous system function in adults, as well as in chronic brain disorders and various acute brain injuries.”
