abstract = {Purpose: Approximately 90% of concussions are transient, with symptoms resolving within 10\textendash14 days. However, a minority of patients remain symptomatic several months post-injury, a condition known as post-concussion syndrome (PCS). The treatment of these patients can be challenging. The goal of our study was to assess the utility and cost-effectiveness of neurologic imaging two or more weeks post-injury in a cohort of youth with PCS. Methods: We conducted a retrospective study of 52 pediatric patients with persistent post-concussion symptoms after 3 months. We collected demographics and neuroimaging results obtained greater than 2 weeks post-concussion. Neuroimaging ordered in the first 2 weeks post-concussion was excluded, except to determine the rate of re-imaging. Descriptive statistics and corresponding cost data were collected. Results: Of 52 patients with PCS, 23/52 (44 %) had neuroimaging at least 2 weeks after the initial injury, for a total of 32 diagnostic studies. In summary, 1/19 MRIs (5.3 %), 1/8 CTs (13 %), and 0/5 x-rays (0 %) yielded significant positive findings, none of which altered clinical management. Chronic phase neuroimaging estimated costs from these 52 pediatric patients totaled $129,025. We estimate the cost to identify a single positive finding was $21,000 for head CT and $104,500 for brain MRI. Conclusions: In this cohort of pediatric PCS patients, brain imaging in the chronic phase (defined as more than 2 weeks after concussion) was pursued in almost half the study sample, had low diagnostic yield, and had poor cost-effectiveness. Based on these results, outpatient management of pediatric patients with long-term post-concussive symptoms should rarely include repeat neuroimaging beyond the acute phase. © 2015, Springer-Verlag Berlin Heidelberg.},

abstract = {Background: Sports are a major cause of concussions, and little is known about the symptom experience and health-related quality of life (HRQL) in children who remain symptomatic for over 3 months following such head injuries. Methods: A cross-sectional study of children aged 10-18 years was performed who were referred to the Neurosurgery Clinic at our centre following a head injury. Symptom experience was measured using the modified Concussion Symptom Scale, and HRQL was measured using the Pediatric Quality of Life Inventory (PedsQL). The Immediate Postconcussion Assessment and Cognitive Test (ImPACT) was administered to assess neurocognitive and neurobehavioural sequelae. Results: Symptoms with the highest mean symptom scores on a Likert scale of 0-6 in 35 children at the time of assessment included headaches (3.1), poor concentration (2.7), memory problems (2.1), fatigue (2.1) and sensitivity to noise (2.0). Compared with normative data, children in this study had ImPACT summary scores between the 28th and 38th percentiles and a comparably low Cognitive Efficiency Index score. Mean scores for females were consistently statistically significantly lower (p \< 0.05) than for males across all of the HRQL domains. Trouble falling asleep and memory problems explained 62% of the variance in the PedsQL total scores. Conclusions: Children continue to experience many symptoms at least 3 months following sport-related head injuries that significantly impact their HRQL and neurocognitive abilities. © 2015 S.

abstract = {Context: Chronic traumatic encephalopathy (CTE) is a rare progressive neurologic disorder that can manifest as a combination of cognitive, mood and behavioral, and neurologic symptoms. Despite clinically apparent symptoms, there is no imaging or other diagnostic test that can confirm diagnosis in living subjects. Diagnosis can only be confirmed postmortem by specific histopathologic features within the brain tissue identified on autopsy. CTE represents a unique tauopathy that is distinct from other neurodegenerative diseases. Evidence Acquisition: PubMed was searched from 1990 to 2013 for sport concussion and chronic traumatic encephalopathy. Articles were also identified from bibliographies of recent reviews and consensus statements. Study Design: Clinical review. Level of Evidence: Level 5. Results: Although CTE is postulated to occur as a result of repetitive mild traumatic brain injury, the specific etiology and risk factors have not yet been elucidated, and postmortem diagnosis makes causality difficult to determine. Conclusion: When counseling athletes and families about the potential association of recurrent concussions and the development of CTE, discussion of proper management of concussion is cornerstone. Unfortunately, to date, there is no equipment that can prevent concussions; however, rule changes and legislation may decrease the risk. It is imperative that return to play is medically supervised by a provider trained in the management of concussion and begins only once symptoms have resolved. In addition, athletes with permanent symptoms should be retired from contact sport. © 2014 The Author(s).},

Evidence based diagnostic guidelines have been established,1 but the diagnosis and treatment are largely grounded in clinical decision-making. Clinical and research issues around sports concussion have even reached the levels of government policy with the White House. At the moderate to severe range of traumatic brain injury, neuroimaging provides well-established, objective pathoanatomical biomarkers of the injury. In contrast, conventional neuroimaging findings in mTBI are typically absent. The cognitive and neurobehavioral symptoms of mTBI overlap with any number of neurologic or psychiatric disorders, providing no definitive marker of injury or for tracking injury effects. Reliable biomarkers of mTBI could lead to better clinical decision-making and potential treatments. Deformation-based biomechanical studies of mTBI have shown the thalamus is situated in a particularly vulnerable zone. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

(The following abstract of the original article appeared in record [rid]2010-23062-009[/rid]). Concussive head injury opens a temporary window of brain vulnerability due to the impairment of cellular energetic metabolism. As experimentally demonstrated, a second mild injury occurring during this period can lead to severe brain damage, a condition clinically described as the second impact syndrome. To corroborate the validity of proton magnetic resonance spectroscopy in monitoring cerebral metabolic changes following mild traumatic brain injury, apart from the magnetic field strength (1.5 or 3.0 T) and mode of acquisition, we undertook a multicentre prospective study in which a cohort of 40 athletes suffering from concussion and a group of 30 control healthy subjects were admitted. Athletes (aged 16\textendash35 years) were recruited and examined at three different institutions between September 2007 and June 2009. They underwent assessment of brain metabolism at 3, 15, 22 and 30 days post-injury through proton magnetic resonance spectroscopy for the determination of N-acetylaspartate, creatine and choline-containing compounds. Values of these representative brain metabolites were compared with those observed in the group of non-injured controls. Comparison of spectroscopic data, obtained in controls using different field strength and/or mode of acquisition, did not show any difference in the brain metabolite ratios. Athletes with concussion exhibited the most significant alteration of metabolite ratios at Day 3 post-injury (N-acetylaspartate/creatine: −17.6%, N-acetylaspartate/choline: −21.4%; P \< 0.001 with respect to controls). On average, metabolic disturbance gradually recovered, initially in a slow fashion and, following Day 15, more rapidly. At 30 days post-injury, all athletes showed complete recovery, having metabolite ratios returned to values detected in controls. Athletes self-declared symptom clearance between 3 and 15 days after concussion. Results indicate that N-acetylaspartate determination by proton magnetic resonance spectroscopy represents a non-invasive tool to accurately measure changes in cerebral energy metabolism occurring in mild traumatic brain injury. In particular, this metabolic evaluation may significantly improve, along with other clinical assessments, the management of athletes suffering from concussion. Further studies to verify the effects of a second concussive event occurring at different time points of the recovery curve of brain metabolism are needed.

abstract = {INTRODUCTION: Problems with balance and dizziness are one of the most common complaints of individuals who have experienced a brain injury and are reported in up to 90% of cases. Despite the ubiquity of vestibular disturbance in this population, there remains a dearth of research on the interaction between physiological and cognitive systems responsible for maintaining balance. PURPOSE: The purpose of this article is to review studies on the interaction of physiological and cognitive processes required to maintain balance that may aide assessment and recovery of balance disturbance in patients with brain injury. SUMMARY: This article provides a review of research on the role of higher order cognitive processes in maintaining balance and rational for further inclusion of neurocognitive measures in the assessment of vestibular disturbance. CONCLUSION: Greater inclusion of neurocognitive measures in assessment of vestibular disturbance provides a method of assessment containing increased ecological validity compared to traditional assessments, better prepares patients for discharge, and may reduce the incidence of future injury.},

Two different approaches to intervention and treatment for those with a suspected concussion from a work-related injury were utilised by an urban, interdisciplinary, outpatient rehabilitation facility. The first approach, Group Treatment (GT), provided minimal early education at time of initial intake, emphasising an extensive group-focused interdisciplinary assessment and treatment. The second approach, Individualized Education and Treatment, (IET) emphasised early education, instead coupled with specific individualised services. Both groups received employment services. Post-discharge, GT ( N = 26) resulted in 46% ( n = 12) of individuals returning to competitive employment, while IET ( N = 23) resulted in 78% ( n = 18) of individuals returning to competitive employment. An asset-oriented early individualised educational approach appears to be a more effective for employment re-engagement. ABSTRACT FROM AUTHOR},

abstract = {Primary objective: To evaluate low-level to complex information processing using visual electrophysiology and to examine the latter's prognostic value in regards to vocational outcome in persons having sustained a mild traumatic brain injury (mTBI). Research design/methods: Event-related potentials (ERPs) were recorded to pattern-reversal, simple motion, texture segregation and cognitive oddball paradigms from 17 participants with symptomatic mTBI at onset of specialized clinical intervention and from 15 normal controls. The relationship between abnormal electrophysiology and post-intervention return to work status was also examined. Main outcomes and results: Participants with mTBI showed a statistically significant (p \< .05) amplitude reduction for cognitive ERPs and delayed latencies for texture (p \< .05) and cognitive paradigms (p \< .005) compared to controls. Furthermore, participants with mTBI presenting texture or cognitive ERP latency delays upon admission were at significantly (p \< .01) greater risk of negative vocational outcome than mTBI participants with normal electrophysiology. Conclusions: The findings suggest that individuals with symptomatic mTBI can present selective deficits in complex visual information processing that could interfere with vocational outcome. ERP paradigms such as those employed in this study thus show potential for evaluating outcome prognosis and merit further study. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

Results from studies examining the development of more persistent symptoms have found relationships with a number of psychological factors, including expectation and maladaptive coping styles. Systematic reviews of intervention strategies have indicated that psychological approaches to treatment of MTBI, such as early education and support, are more effective than any form of drug treatment.
