BACKGROUND/OBJECTIVE: Conventional neuroimaging is not recommended for the routine diagnosis of concussion, but some patients with concussion undergo computed tomography (CT) or magnetic resonance imaging (MRI). The objective of this study was to explore the clinical factors that predict neuroimaging utilization in concussion. METHODS: Concussion-related CT and MRI data were analysed from 1953 patients, aged 10-19 years, who presented to a sports concussion clinic within 30 days of injury...

BACKGROUND: Though recovery after concussion is spontaneous and typically occurs within two to three weeks, a subset of adolescents develop persistent symptoms after a sports-related concussion. Medications are frequently prescribed as part of a comprehensive treatment approach to alleviate these symptoms; however, there are no guidelines for prescription of pharmacologic therapy after concussion. OBJECTIVE: To investigate common factors that are associated with the use of medications (anti-epileptic, anti-depressant, neurostimulant, or sleeping medication) during recovery from a sports-related concussion...

The Assessment of Military Multitasking Performance (AMMP) is a battery of functional dual-tasks and multitasks based on military activities that target known sensorimotor, cognitive, and exertional vulnerabilities after concussion/mild traumatic brain injury (mTBI). The AMMP was developed to help address known limitations in post concussive return to duty assessment and decision making. Once validated, the AMMP is intended for use in combination with other metrics to inform duty-readiness decisions in Active Duty Service Members following 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...

REVIEW
William Johnston, Garrett F Coughlan, Brian Caulfield
The assessment and management of sports-related concussion has become a contentious issue in the field of sports medicine. The current consensus in concussion evaluation involves the use of a subjective examination, supported by multifactorial assessment batteries designed to target the various components of cerebral function. Balance assessment forms an important component of this multifactorial assessment, as it can provide an insight into the function of the sensorimotor subsystems post-concussion. In recent times, there has been a call to develop objective clinical assessments that can aid in the assessment and monitoring of concussion...

OBJECTIVE: Evidence from previous studies suggests that greater sleep pressure, in the form of EEG-based slow waves, accumulates in specific brain regions that are more active during prior waking experience. We sought to quantify the number and coherence of EEG slow waves in subjects with mild traumatic brain injury (mTBI). METHODS: We developed a method to automatically detect individual slow waves in each EEG channel, and validated this method using simulated EEG data...

INTRODUCTION: Mild traumatic brain injury (mTBI) has traditionally been considered to cause no significant brain damage since symptoms spontaneously remit after a few days. However, this idea is facing increasing scrutiny. The purpose of this study is to demonstrate the presence of early cognitive alterations in a series of patients with mTBI and to link these findings to different markers of brain damage. METHODS: We conducted a prospective study of a consecutive series of patients with mTBI who were evaluated over a 12-month period...

Statins constitute a class of medications commonly used in the treatment of elevated cholesterol. However, in experimental studies statins also have other non-cholesterol mediated mechanisms of action, which may have neuroprotective effects. The purpose of this study was to determine if administration of atorvastatin for 7 days after injury would improve neurological recovery in patients with mild traumatic brain injury (mTBI). The hypothesis was that atorvastatin administration would reduce post-concussion symptoms and also that atorvastatin administration for one week post-injury would be safe...

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...

The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to assess cognitive functioning after a concussion. It is recommended that application of ImPACT utilizes a baseline administration so athletes have an individualized baseline with which to compare post-injury results should they sustain a concussion. It has been suggested that athletes may provide suboptimal effort, called "sandbagging," in order to return to their baseline cognitive scores, and thus to play, more quickly...

OBJECTIVES: Concussion is defined as a complex pathophysiological process affecting the brain. Although the cumulative and long-term effects of multiple concussions are now well documented on cognitive and motor function, little is known about their effects on emotion recognition. Recent studies have suggested that concussion can result in emotional sequelae, particularly in females and multi-concussed athletes. The objective of this study was to investigate sex-related differences in emotion recognition in asymptomatic male and female multi-concussed athletes...

Post-concussion impairments may result in unsafe driving performance, but little research is available to guide consensus on when concussed individuals should return to driving. The purpose of this study was to compare driving performance between individuals with and without a concussion and to explore relationships between neuropsychological and driving performance. Fourteen participants with concussion (Age:20.2±0.9yo) and 14 non-concussed age and driving experience matched controls (Age:20.4±1.1yo) completed a graded symptom checklist, a brief neuropsychological exam, and a 20...

INTRODUCTION: Nurse practitioners (NPs) are authorized to manage concussion recovery. Common adolescent activities, like driving, are omitted from guidelines. We investigated NP driving guidance and its clinical basis for restriction or limitation following adolescent concussion. METHOD: NPs completed a web-based questionnaire after viewing a scripted video scenario of an adolescent describing symptoms of concussion occurring 72 hours prior. Driving recommendations were collected using an open-ended query, then coded and categorized by type, characteristic, and basis...

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...

INTRODUCTION: Mild traumatic brain injury (mTBI) outcomes are variable, and 10-15% may suffer from prolonged symptoms beyond 3 months that impair the child's return to normal activities. Neurophysiological mechanisms of mTBI are incompletely understood, particularly in children, but alterations in cortical excitability have been proposed to underlie post-concussion syndrome. Improved understanding is required to advance interventions and improve outcomes. OBJECTIVE/HYPOTHESIS: To determine if cortical excitability is altered in children with mTBI, and its association with clinical symptoms...
