The aim of this study was to examine the potential utility of a self-paced saccadic eye movement as a marker of post-concussion syndrome (PCS) and monitoring the recovery from PCS. Fifty-nine persistently symptomatic participants with at least two concussions performed the self-paced saccade (SPS) task. We evaluated the relationships between the number of SPSs and (i) number of self-reported concussion symptoms, and (ii) integrity of major WM tracts (as measured by fractional anisotropy [FA], and mean diffusivity [MD]) that are directly or indirectly involved in saccadic eye movements and often affected by concussion...

OBJECTIVES: There are notable gender differences in concussion as well as sleep. Sleep disturbance is a major symptom of post-concussive syndrome. The interplay between sleep disturbance, concussion, and gender has yet to be examined. The objective of this study was to determine whether sleep disturbance plays a role in the known gender differences associated with concussion. METHODS: Males and females (ages 10-35 years) completed a pre-concussion and post-concussion evaluation...

In this study, a noninvasive quantitative measure was used to identify short and long term post-concussion syndrome (PCS) both from each other and from healthy control populations. We used Electrovestibulography (EVestG) for detecting neurophysiological PCS consequent to a mild traumatic brain injury (mTBI) in both short-term (N = 8) and long-term (N = 30) (beyond the normal recovery period) symptomatic individuals. Peripheral, spontaneously evoked vestibuloacoustic signals incorporating - and modulated by - brainstem responses were recorded using EVestG, while individuals were stationary (no movement stimulus)...

INTRODUCTION: Pediatric head trauma is one of the commonest presentations to emergency departments. Over 90% of such head injuries are considered mild, but still present risk acute clinical deterioration and longer term morbidity. Identifying which children are at risk of clinically important brain injuries remains challenging and much of the data on minor head injuries is based on the adult population. CHALLENGES IN PEDIATRICS: Children, however, are different, both anatomically and in terms of mechanism of injury, to adults and, even within the pediatric group, there are differences with age and stage of development...

Post-concussion syndrome (PCS) is often caused by an uncomplicated mild head injury but followed by long-lasting somatic, cognitive and psychiatric symptoms. For many years PCS has been an area of controversy between clinicians. New diagnostic techniques and clinical researches has shed light to some neurobiological aspects behind PCS. In Diagnostic and Statistical Manual of Mental Disorders V PCS is redefined as a neuro-cognitive condition emphasizing the importance of neuropsychological deficits among these patients...

BACKGROUND: A minority of patients with mild traumatic brain injury (mTBI) experience a persistent symptom complex also known as post-concussion syndrome. Explanations for this syndrome are still lacking. OBJECTIVE: To investigate if the fear avoidance model, including catastrophizing thoughts and fear avoidance behaviour, poses a possible biopsychosocial explanation for lingering symptoms and delay in recovery after traumatic brain injury (TBI) with special focus on mTBI...

This systematic review and meta-analysis aimed to determine the prognostic value of S-100β protein to identify patients with post-concussion symptoms following a mild traumatic brain injury (mTBI). A search strategy was submitted to seven databases from their inception to October 2016. Individual patient data were requested. Cohort studies evaluating the association between S-100β protein level and post-concussion symptoms assessed at least seven days after the mTBI were considered. Outcomes were dichotomised as persistent (>= 3 months) or early (>= 7 days < 3 months)...

OBJECTIVE: Mild traumatic brain injury (mTBI) has been insufficiently researched, and its definition remains elusive. Investigators are confronted by heterogeneity in patients, mechanism of injury and outcomes. Findings are thus often limited in generalisability and clinical application. Serum protein biomarkers are increasingly assessed to enhance prognostication of outcomes, but their translation into clinical practice has yet to be achieved. A systematic review was performed to describe the adult populations included and enrolled in studies that evaluated the prognostic value of protein biomarkers to predict postconcussion symptoms following an mTBI...

Clinical Scenario: Patients who experience prolonged concussion symptoms can be diagnosed with Post-Concussion Syndrome (PCS) when those symptoms persist past 4 weeks. Aerobic exercise protocols have been shown to be effective in improving physical and mental aspects of health. Emerging research suggests that aerobic exercise maybe useful as a treatment for PCS, where exercise allows patients to feel less isolated and more active during the recovery process. CLINICAL QUESTION: Is aerobic exercise more beneficial in reducing symptoms than current standard care in patients with prolonged symptoms or PCS lasting longer than 4 weeks? Summary of Key Findings: After a thorough literature search, 4 studies were selected relevant to the clinical question...

Mild traumatic brain injury (mTBI) is a complex, neurophysiological condition that can have detrimental outcomes. Yet, to date, no objective method of diagnosis exists. Physical damage to the blood-brain-barrier and normal waste clearance via the lymphatic system may enable the detection of biomarkers of mTBI in peripheral circulation. Here we evaluate the accuracy of whole transcriptome analysis of blood to predict the clinical diagnosis of post-concussion syndrome (PCS) in a military cohort. Sixty patients with clinically diagnosed chronic concussion and controls (no history of concussion) were recruited (retrospective study design)...

Although the King-Devick (K-D) test has been used frequently in assessing sports related concussion early after injury, its characteristics over time after injury and in patients with prolonged persistent symptoms are unknown. The purpose of this paper was to: evaluate the ability of the K-D Test to distinguish patients seen early after concussion from those with symptoms persisting more than 3 months compared to controls, assess changes in the K-D test times over time after concussion, and determine the relationship of K-D times to the Stroop Color and Word Test scores...

A small but significant proportion of mild traumatic brain injury (mTBI) sufferers will report persistent symptoms, including depression, anxiety and cognitive deficits, in the months, or even years, following the initial event. This is known as post-concussion syndrome and its pathogenesis is not yet known. This study sought to investigate the role of a peripheral inflammatory insult in the development of ongoing behavioral symptoms following a mTBI. To investigate, male Sprague-Dawley rats were administered a single mTBI using the diffuse impact-acceleration model to generate ∼100G of force...
