OBJECTIVE: To determine whether central and peripheral vision reaction times (PVRTs) are prolonged in patients with visual dysfunction after sustaining a concussion. DESIGN: Comparison of Dynavision D2 central and PVRTs in patients with postconcussion visual dysfunction were compared with control data from a normative patient database. Concussion patients without visual dysfunction were not included in this study. SETTING: National Collegiate Athletic Association Division 1 college training room and university based, academic health center...

OBJECTIVE: Traumatic brain injury (TBI) occurs in a substantial minority of military personnel, and commonly is associated with mental health disorders and postconcussive symptoms (PCS). The implications of TBI for mental health treatment are not well understood. The present study sought to describe psychotherapy response in veterans with and without TBI. DESIGN: This is a secondary analysis from a 2-group randomized controlled trial. SETTING, PARTICIPANTS, AND MEASURES: One hundred and sixty male and female veterans participated in a multisite randomized controlled trial of Acceptance and Commitment Therapy versus Present Centered Therapy; a subset of 129 veterans were included in these analyses...

BACKGROUND: Acute symptoms of dizziness and/or imbalance commonly experienced in athletes postconcussion are speculated to arise from dysfunction at multiple levels (i.e., inner ear or central vestibular system) to appropriately integrate afferent sensory information. Disruption along any pathway of the balance system can result in symptoms of dizziness, decreased postural control function (vestibulospinal reflex), and reduced vestibulo-ocular reflex function. This may also lead to decreased gaze stability with movements of the head and may account for symptoms of blurred vision or diplopia reported in almost half of athletes sustaining a concussion...

Although most patients with a mild traumatic brain injury (mTBI) recover within days to weeks, some experience persistent physical, cognitive and emotional symptoms, often described as postconcussion syndrome (PCS). The optimal recovery time including return-to-work (RTW) after mTBI is unclear. In this single-centre parallel-group trial, patients assigned three days (3D-group) or seven days (7D-group) sick leave were compared with a comprehensive neuropsychological test battery including the Post Concussion Symptom Scale (PCSS) within one week, after three and twelve months post-injury...

Importance: Although concussion treatment guidelines advocate rest in the immediate postinjury period until symptoms resolve, no clear evidence has determined that avoiding physical activity expedites recovery. Objective: To investigate the association between participation in physical activity within 7 days postinjury and incidence of persistent postconcussive symptoms (PPCS). Design, Setting, and Participants: Prospective, multicenter cohort study (August 2013-June 2015) of 3063 children and adolescents aged 5...

We sought to further define the epidemiology of the complex, multiple injuries collectively known as polytrauma/blast-related injury (PT/BRI). Using a systems science approach, we performed Bayesian network modeling to find the most accurate representation of the complex system of PT/BRI and identify key variables for understanding the subsequent effects of blast exposure in a sample of Florida National Guard members (1,443 deployed to Operation Enduring Freedom/Operation Iraqi Freedom and 1,655 not deployed) who completed an online survey during the period from 2009 to 2010...

BACKGROUND: Research on the acute effects of a concussion among lacrosse players is limited, and postconcussion patterns between male and female athletes have yet to be clearly established. Differences in the style of play and protective gear worn among male and female lacrosse players potentially confound a direct comparison of sex-based differences in this population. PURPOSE: To explore sex-based differences in postconcussive neurocognitive functioning and symptom reporting outcomes in concussed adolescent male and female lacrosse players compared with a group of soccer players...

OBJECTIVE: We sought to examine the prevalence, scope, and specificity of provisions governing school reintegration in current state concussion laws. METHODS: State concussion laws as of May 2016 were independently assessed and classified by 2 trained coders. Statutes were classified as "Return-to-Learn" (RTL) laws if they contained language mandating institutional action at the state, district, or school level related to academic reintegration of youth who have sustained a concussion...

CONTEXT:  Computerized neurocognitive assessments are commonly used to manage sport-related concussion. Variations in baseline performance may influence neurocognitive performance after injury as well as the amount of time needed for an athlete to be cleared for return to sport participation. OBJECTIVE:  To investigate the relationship between mean baseline Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) scores and postconcussion reliable decline as well as the association between postconcussion cognitive decline and days missed after injury...

BACKGROUND: Impaired balance is common after concussion. The third edition of the Sport Concussion Assessment Tool (SCAT-3) recommends the Balance Error Scoring System (BESS) and/or tandem gait for postconcussion balance assessment. The limitations of the BESS are well documented; however, tandem gait has received little attention throughout concussion literature. The purpose of this study was to provide normative data for tandem gait in collegiate student-athletes based on sport type, concussion history, and gender...

Approximately 20% of current-era Veterans have sustained a traumatic brain injury (TBI), which can result in persistent postconcussive symptoms. These symptoms may disrupt family and social functioning. We explored psychiatric, postconcussive, and cognitive factors as correlates of objective functioning and subjective satisfaction in family and social relationships. At entry into a supported employment study, 50 unemployed Veterans with a history of mild to moderate TBI and current cognitive impairment were administered baseline assessments...

As the awareness of concussions increases, it is imperative to be able to evaluate, diagnose, and treat concussed individuals properly to prevent further complications or death. The primary purpose of this study was to compare a provider's current awareness and comfort level as it relates to the return-to-play guidelines for concussions. A secondary aim was to evaluate current protocols that are in use and determine whether they coincide with the suggested guidelines. An educational intervention was implemented to assess the knowledge and confidence of health care providers...

: Clinical Scenario: Concussions are a prevalent topic in medicine. Concussion symptoms include headaches, dizziness, nausea, neuropsychiatric symptoms, and cognitive impairments, the persistence of these referred to as postconcussion syndrome. The use of hyperbaric oxygen therapy (HBOT) has been proposed and evaluated as an additional treatment of these symptoms. Using HBOT is an innovative approach that has been considered by many, but has received both criticism and acceptance. CLINICAL QUESTION: Is hyperbaric oxygen therapy treatment an effective means of reducing symptoms for individuals suffering from postconcussion syndrome (persistence of symptoms for > 3 months)? Summary of Search: The literature was searched for studies that were relevant to the clinical question...

Education to improve symptom management is an agreed-upon strategy to reduce the impact of symptoms on the quality of life for persons with mild traumatic brain injury. The purpose of this study was to investigate whether current discharge education practices are deemed adequate by persons treated and released from the emergency department with concussion. A review of current literature identified a need for patient education improvements in emergency departments. Strategies for improving information retention in the mild traumatic brain injury patient population for effective symptom management are identified...

Blast-related mild traumatic brain injury (mTBI) has been unfortunately common in veterans who served in the recent conflicts in Iraq and Afghanistan. The postconcussion syndrome associated with these mTBIs has frequently appeared in combination with post-traumatic stress disorder (PTSD). The presence of PTSD has complicated diagnosis, since clinically, PTSD and the postconcussion syndrome of mTBI have many overlapping symptoms. In particular, establishing how much of the symptom complex can be attributed to the psychological trauma associated with PTSD in contrast to the physical injury of traumatic brain injury has proven difficult...
