OBJECTIVE: Attention deficit hyperactivity disorder (ADHD) and other academically-relevant diagnoses have been suggested as modifiers of neurocognitive testing in sport-related concussion, such as Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). These preexisting conditions may suppress ImPACT scores to the extent that they are indistinguishable from low scores because of poor effort. The present study hypothesized that student athletes with history of ADHD or academic difficulties produce lower ImPACT composite scores and are more likely to produce invalid protocols than those without such conditions...

OBJECTIVE: The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a commonly used tool in sports concussion assessment. While test-retest reliabilities have been established for the ImPACT cognitive composites, few studies have evaluated the psychometric properties of the ImPACT's Post-Concussion Symptom Scale (PCSS). The purpose of this study was to establish the test-retest reliability of symptom indices associated with the PCSS. PARTICIPANTS AND METHODS: Participants included 38 undergraduate students (50...

OBJECTIVE: This study investigated the utility of sideline concussion tests, including components of the Sports Concussion Assessment Tool, 3rd Edition (SCAT3) and the King-Devick (K-D), a vision-based test of rapid number naming, in an outpatient, multidisciplinary concussion center treating patients with both sports-related and non-sports related concussions. The ability of these tests to predict clinical outcomes based on the scores at the initial visit was evaluated. METHODS: Scores for components of the SCAT3 and the K-D were fit into regression models accounting for age, gender, and sport/non-sport etiology in order to predict clinical outcome measures including total number of visits to the concussion center, whether the patient reached a SCAT3 symptom severity score≤7, and the total types of referrals each patient received over their course...

The search for effective treatment facilitating recovery from concussive injury, as well as reducing risk for recurrent concussion is an ongoing challenge. This study aimed to determine: a) feasibility of selective brain cooling to facilitate clinical symptoms resolution, and b) biological functions of the brain within athletes in acute phase of sports-related concussion. Selective brain cooling for 30 minutes using WElkins sideline cooling system was administered to student-athletes suffering concussive injury (n=12; tested within 5±3 days) and those without history of concussion (n=12)...

BACKGROUND: Several professional contact and collision sports have recently introduced the use of sideline video review for club medical staff to help identify and manage concussions. As such, reviewing video footage on the sideline has become increasingly relied upon to assist with improving the identification of possible injury. However, as yet, a standardized method for reviewing such video footage in rugby league has not been published. The aim of this study is to evaluate whether independent raters reliably agreed on the injury characterization when using a standardized observational instrument to record video footage of National Rugby League (NRL) concussions...

PURPOSE: Sports related concussion (SRC) is a risk for players involved in high impact, collision sports. A history of SRC is a risk factor for future concussions, but the mechanisms underlying this are unknown. Despite evidence that most visible signs and symptoms associated with sports concussion resolve within 7-10 days, it has been proposed that subclinical loss of neuromuscular control and impaired motor functioning may persist and be associated with further injury. Alternatively, indicators of poor sensorimotor performance could be independent risk factors...

OBJECTIVE: The growth in participation in men's lacrosse has increased the likelihood of sport-specific injuries. Despite the exponential growth in men's lacrosse participation, there continues to be a need for specific epidemiological data concerning lacrosse injuries. The sport's rapid growth in participation could have a profound effect on injury prevalence characteristics. The purpose of this literature review is to aggregate available published data on injuries that occur in the sport of men's lacrosse at the youth, high school, collegiate, and professional levels...

Sport-related concussion is a frequent and complex pathology whose physiopathological mechanisms are not completely understood yet. A recent consensus statement has been published with the objective to provide practicioners with an overview of literature and give some guidelines based on the current state of knowledge. An 11R approach (Recognise, Remove, Re-evaluate, Rest, Rehabilitation, Refer, Recover, Return to sport, Reconsider, Residual effects and sequelae, Risk reduction) is proposed to evaluate and manage sport-related concussion...

There is a pressing need to identify objective biomarkers for the assessment of sport-related concussion to reduce the reliance on clinical judgment for the management of these injuries. The goal of the current study was to prospectively establish the acute effects of sport-related concussion (SRC) on serum levels of S100B, GFAP, and UCH-L1. Collegiate and high school football players were enrolled and provided blood at preseason. Injured athletes participated in follow-up visits at approximately 6 and 24-48 hours following documented SRC (N=32)...

Concussions are common neurologic events that affect many athletes. Very little has been studied on the treatment of concussions with supplements and medications. The U.S. Food and Drug Administration (FDA) reminds us that no supplement has been proven to treat concussions. Many animal studies show that supplements have potential for improving the effects of a brain injury but none have been shown to be of consistent benefit in human studies. Animal studies on severe traumatic brain injury (TBI) may not therefore be applicable transfer to sports-related concussions (SRC)...

Despite the high prevalence of traumatic brain injuries (TBI), there are few rapid and straightforward tests to improve its assessment. To this end, we developed a tablet-based software battery ("BrainCheck") for concussion detection that is well suited to sports, emergency department, and clinical settings. This article is a study of the diagnostic accuracy of BrainCheck. We administered BrainCheck to 30 TBI patients and 30 pain-matched controls at a hospital Emergency Department (ED), and 538 healthy individuals at 10 control test sites...

Mild traumatic brain injury (mTBI), common in juveniles, has been reported to be caused by sports-related concussion. Many young children may suffer from post-concussion syndrome. mTBI, in early stages of life, could play a part in neuron apoptosis and degeneration, cognitive and motor coordination impairment, as well as dementia. Our study was aimed at further investigating the post therapeutic efficacy of rapamycin in the recuperation of mTBI whiles at the same time investigating the metamorphosis in both autophagy and mitophagy in mTBI...

With 300 million riders annually, roller coasters are a popular recreational activity. Although the number of roller coaster injuries is relatively low, the precise effect of roller coaster rides on our brain remains unknown. Here we present the quantitative characterization of brain displacements and deformations during roller coaster rides. For two healthy adult male subjects, we recorded head accelerations during three representative rides, and, for comparison, during running and soccer headers. From the recordings, we simulated brain displacements and deformations using rigid body dynamics and finite element analyses...

The influence of the falx and tentorium on brain injury biomechanics during impact was studied with finite element (FE) analysis. Three detailed 3D FE head models were created based on the images of a healthy, normal size head. Two of the models contained the addition of falx and tentorium with material properties from previously published experiments. Impact loadings from a reconstructed concussive case in a sport accident were applied to the two players involved. The results suggested that the falx and tentorium could induce large strains to the surrounding brain tissues, especially to the corpus callosum and brainstem...
