The Sport Concussion Assessment Tool (SCAT2) for evaluating civilian mild traumatic brain injury. A pilot normative study.

PLoS One 2019 20;14(2):e0212541. Epub 2019 Feb 20.

Neurotraumatology and Neurosurgery Research Unit (UNINN), Vall d'Hebron Research Institute (VHIR), Barcelona, Spain.

Self-report measures, particularly symptom inventories, are critical tools for identifying patients with persistent post-concussion symptoms and their follow-up. Unlike in military or sports-related assessment, in general civilian settings pre-injury levels of concussion-like symptoms are lacking. Normative data are available in adolescent and college populations, but no reference data exist to guide clinical adult explorations. Read More

Factors contributing to parent-child interaction quality following mild traumatic brain injury in early childhood.

J Neuropsychol 2019 Feb 19. Epub 2019 Feb 19.

Ste-Justine Research Center, Montreal, Quebec, Canada.

There is emerging evidence that parent-child interactions are affected by early childhood traumatic brain injury (TBI). These findings are of functional importance when considering the high prevalence of TBI in early childhood alongside evidence that young children exposed to positive relationships with their parents early in life exhibit better social functioning concurrently and longitudinally. Given that the overall quality of parent-child interactions is the result of both parent and child emotional and behavioural dispositions, it remains unclear which parental or child-related factors contribute to the quality of interactions post-TBI.

NFL blood levels are moderated by subconcussive impacts in a cohort of college football players.

Brain Inj 2019 11;33(4):456-462. Epub 2019 Jan 11.

d Department of Neuroscience , Lewis Katz School of Medicine at Temple University , Philadelphia , PA , USA.

Introduction: Repetitive subconcussive head impacts in contact/collision sports such as in US football are believed to contribute to long-term brain changes and chronic symptoms. However, the lack of tools to measure the effects of repeated subconcussion limits our understanding of potential contributions to neuropathological alterations including cellular damage.

Methods: We examined subconcussive head impacts using an accelerometer-embedded mouthguard on changes in blood levels of neurofilament light (NFL) chain in 18 Division I college football players. Read More

DNA damage as a marker of brain damage in individuals with history of concussions.

Lab Invest 2019 Feb 13. Epub 2019 Feb 13.

Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, ON, Canada.

Mild traumatic brain injury (mTBI) is common in many populations, including athletes, veterans, and domestic abuse victims. mTBI can cause chronic symptoms, including depression, irritability, memory problems, and attention deficits. A history of repetitive mTBI has been epidemiologically associated with developing early-onset dementia and neurodegenerative diseases and, in particular, is thought to be the underlying cause of chronic traumatic encephalopathy (CTE)-a progressive tauopathy diagnosed by the presence of perivascular hyperphosphorylated tau protein (p-tau) in the depths of cortical sulci.

The role of cervical muscles in mitigating concussion.

J Sci Med Sport 2019 Jan 18. Epub 2019 Jan 18.

Injury Biomechanics Laboratory, Department of Biomedical Engineering, Duke University, United States.

Objectives: Increased neck strength has been hypothesized to lower sports related concussion risk, but lacks experimental evidence. The goal is to investigate the role cervical muscle strength plays in blunt impact head kinematics and the biofidelity of common experimental neck conditions. We hypothesize head kinematics do not vary with neck activation due to low short term human head-to-neck coupling; because of the lack of coupling, free-head experimental conditions have higher biofidelity than Hybrid III necks.

Disrupted motor performance is increasingly recognized as a critical sequela of concussion which may have relevance for diagnosis and treatment. In 17 adolescents with recent concussion and 20 never-concussed controls, we evaluated the discriminant ability of a commonly used neurocognitive measure compared to a motor subtle sign exam, which evaluates gait, balance, and fine and gross motor control. We found that the motor subtle sign exam had better discriminant ability than the neurocognitive measure, but combining both measures was superior to analyses with individual measures (Wilks' ƛ = .

Development and validation of a high-speed video system for measuring saccadic eye movement.

Behav Res Methods 2019 Jan 31. Epub 2019 Jan 31.

School of Kinesiology, Faculty of Health Sciences, Western University, London, Ontario, Canada.

Laboratory-based retroreflective and magnetic scleral search-coil technologies are the current standards for collecting saccadometric data, but such equipment is costly and cumbersome. We have validated a novel, portable, high-speed video camera-based system (Exilim EX-FH20, Casio, Tokyo, Japan) for measuring saccade reaction time (RT) and error rate in a well-lit environment. This system would enable measurements of pro- and antisaccades in athletes, which is important because antisaccade metrics provide a valid tool for concussion diagnosis and determining an athlete's safe return to play.

American Medical Society for Sports Medicine position statement on concussion in sport.

Br J Sports Med 2019 Feb;53(4):213-225

Department of Family Medicine and Community Health, University of Minnesota, Minneapolis, Minnesota, USA.

Sport-related concussion (SRC) is a common injury in recreational and organised sport. Over the past 30 years, there has been significant progress in our scientific understanding of SRC, which in turn has driven the development of clinical guidelines for diagnosis, assessment and management of SRC. In addition to a growing need for knowledgeable healthcare professionals to provide evidence-based care for athletes with SRC, media attention and legislation have created awareness and, in some cases, fear about many issues and unknowns surrounding SRC.

Long-term factor structure of the Rivermead Post-Concussion Symptom Questionnaire in mild traumatic brain injury and normative sample.

Brain Inj 2019 Jan 30:1-5. Epub 2019 Jan 30.

b National Institute for Stroke and Applied Neuroscience, School of Public health & Psychosocial Studies , Auckland University of Technology , Auckland , New Zealand.

Background: Previous studies of the Rivermead Post-Concussive Questionnaire(RPQ)'s factor structure were conducted within 1 year post-injury. Post-concussive symptoms may persist, and are common in the general population, so determining if the factor structure in mild-TBI and controls differ is important. This study examined factor structure of the RPQ in adults 4 years post-mild-TBI and in age-/gender-matched controls. Read More
