Concussion is a common form of mild traumatic brain injury. Despite the descriptor "mild," a single injury can leave long-lasting and sustained alterations to brain function, including changes to localized activity and large-scale interregional communication. Cognitive complaints are thought to arise from such functional deficits. We investigated the impact of injury on neurophysiological and functionally specialized resting networks, known as intrinsic connectivity networks (ICNs), using magnetoencephalography...

Concussion is associated with significant adverse effects within the first week post-injury, including physical complaints and altered cognition, sleep and mood. It is currently unknown whether these subjective disturbances have reliable functional brain correlates. Resting-state functional magnetic resonance imaging (rs-fMRI) has been used to measure functional connectivity of individuals after traumatic brain injury, but less is known about the relationship between functional connectivity and symptom assessments after a sport concussion...

Catherine D Chong, Todd J Schwedt
Even when concussions are associated with prolonged physical and cognitive sequelae, concussions are typically "invisible" on diagnostic brain imaging, indicating that the neuropathology associated with concussion lies under the detection threshold of routine imaging. However, data from brain structural and functional research imaging studies using diffusion tensor imaging, resting-state functional magnetic resonance imaging, and brain perfusion imaging indicate that these imaging sequences have a role in identifying concussion-related neuropathology...

PURPOSE OF REVIEW: The purpose of this study was to review the frequency, risk factors, phenomenology, and course of prolonged recovery from concussion and of psychiatric sequelae in pediatric populations. RECENT FINDINGS: Youth with prolonged recovery from concussions have higher initial symptoms, a history of multiple and/or recent concussions, and a tendency to somatization. Depression, post-traumatic stress disorder, behavioral disorders, and perhaps, suicidal behavior disorder are more common as both short- and longer-term sequelae of concussions...

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...

Question Despite recent interest in the pathophysiology and management of concussion in children, as well as the ongoing concern about return to activity, advice regarding the type and length of cognitive rest has been inconsistent. What should I recommend to the children and adolescents in my clinic regarding cognitive rest following mild concussion? Answer Strict cognitive rest is not needed in those with mild concussion. Evidence suggests a decrease in usual activity to a level that allows children to remain asymptomatic, followed by a gradual return to learning, is appropriate...

A short cut review was carried out to establish whether strict physical rest following sports related concussion in children is better than normal activity in reducing post-concussional symptoms. two recent systematic reviews presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. It is concluded that children who present with a sport-related concussion should have a brief period of cognitive and physical rest followed by a gradual increase in activity...

Following a concussion, both cognitive and physical rest are imperative aspects of injury management. The inclusion of academic adjustments and the formation of an interprofessional concussion management team (ICMT) provide a mechanism to manage academic issues following a concussion. As one of the sole healthcare providers presents during school hours, the school nurse may offer unique insight regarding the infrastructure of an ICMT in the secondary school setting. The purpose of this study was to explore school nurses' perceptions of and experiences with an ICMT for adolescents following a concussion in the secondary school setting...

OBJECTIVE: While reintegration of concussed youth back into sports has been increasingly studied over the past decade, a noticeably lacking yet growing body of research has begun to focus on issues surrounding return to academics or "return-to-learn" (RTL). The objective of this article was to conduct a comprehensive literature review to identify the full range of themes and gaps in the current body of RTL research. STUDY DESIGN: Researchers analyzed PubMed, PsycINFO, and ERIC databases to identify all recent (January 2000 through May 2016) empirical publications on the RTL process following youth concussions...

Sport-related concussions in young athletes are common, generally under reported and often go unrecognized. Concussion in sport may result either from a direct impact to the head or from indirect forces transmitted to the brain from impact elsewhere on the body. Concussions may also result from sudden acceleration, deceleration or rotational forces to the brain. The key features of concussion include confusion, impaired memory and reduced speed of information processing. Recovery may occur from a few days to several weeks or months...

INTRODUCTION: Rest until symptom-free, followed by a progressive stepwise return to activities, is often prescribed in the management of paediatric concussions. Recent evidence suggests prolonged rest may hinder recovery, and early resumption of physical activity may be associated with more rapid recovery postconcussion. The primary objective is to determine whether the early reintroduction of non-contact physical activity beginning 72 hours postinjury reduces postconcussive symptoms at 2 weeks in children following an acute concussion as compared with a rest until asymptomatic protocol...
