Concussion is currently a serious health problem and can lead to severe brain dysfunction. There is a definite need for sensitive and reliable tests to detect and evaluate the subtle changes in brain function caused by concussion. This study details the development of a low cost portable eye tracking device that can aid in the detection of concussions. The device evaluates ocular motor function and can be used on the sidelines of sporting events to give a quick indication of the severity of head trauma. It can further be used to evaluate and monitor mild Traumatic Brain Injuries and aid in the return to play decision making process...

Assessment, treatment, and management of sport-related concussions are a widely recognized public health issue. Although several neuropsychological and motor assessment tools have been developed and implemented for sports teams at various levels and ages, the sensitivity of these tests has yet to be validated with more objective measures to make return-to-play (RTP) decisions more confidently. The present study sought to analyze the residual effect of concussions on a sample of adolescent athletes who sustained one or more previous concussions compared to those who had no concussion history...

PURPOSE: The injury mechanisms of midfacial fractures may be typical causes of concussion, but hardly any scientific data on midfacial injuries sustained in football are available. Head and brain trauma represent frequent injuries in athletes of different sports that require appropriate treatment by sports and trauma physicians. This study investigated the management of midfacial fractures in football and the association of such fractures with concomitant brain injury. METHODS: In a prospective cohort study lasting 24 months (2012 to 2013), midfacial injuries of football players were analysed with regard to the injury mechanisms, first aid procedures on the field, treatment and return-to-play...

BACKGROUND: Symptoms related to concussion are generally found to be nonspecific in nature, as they are also reported by nonconcussed individuals. What is currently not known is whether the symptoms vary over time, and whether they are also influenced by a multitude of factors. OBJECTIVE: The aim of this study was to investigate the potential influence of psychological, lifestyle, and situational factors on the change in postconcussion-like symptoms reported over 7 consecutive days in a cohort of normal individuals...

Combat sports are growing in popularity, viewership, and participation. The nature of these sports involves repetitive head contact, yet unlike most other professional contact sports, there are no endorsed guidelines or mandates for graduated and systematic return to play following concussion. Here, we review the literature related to concussion and fighting sports, and propose guidelines for concussion management and safe return to play following concussion.

Concussion injury of the brain is still a frequently underestimated injury, which can be associated with long-lasting consequences. Compared to adults, the recovery phase is often prolonged in childhood. Primary treatment consists of symptom-dependent physical and mental activities. Re-integration into daily life is crucial. In childhood, the primary focus is therefore on returning to school. New symptoms, or an increased presence of symptoms must be detected, to avoid prolonged recovery courses. School restrictions have to be minimized...

PURPOSE: Lingering neurologic injury after concussion may expose athletes to increased risk if return-to-play is premature. We explored whether on-field performance after concussion is a marker of lingering neurologic injury. METHODS: Retrospective cohort study on 1,882 skill-position players who played in the National Football League (NFL) during 2007-2010. Players with concussion based on the weekly injury report, were compared to players with other head and neck injuries (controls) on measures of on-field performance using Football Outsiders' calculation of Defense-Adjusted Yards Above Replacement (DYAR): a measure of a player's contribution controlling for game context...

The aim of this study was to evaluate longitudinal changes in the diffusion characteristics of brain white matter (WM) in collegiate athletes at three time points: prior to the start of the football season (T1), after one season of football (T2), followed by six months of no-contact rest (T3). Fifteen male collegiate football players and 5 male non-athlete student controls underwent diffusion MR imaging and computerized cognitive testing at all three timepoints. Whole-brain tract-based spatial statistics (TBSS) were used to compare fractional anisotropy (FA), radial diffusivity (RD), axial diffusivity (AD), and trace between all timepoints...

Concern about what has been termed, "second impact syndrome" (SIS) is a major factor determining return-to-play decisions after concussion. However, definitions of SIS vary. We used Scopus to conduct a systematic review and categorize the definitions used to describe SIS. Of the 91 sources identified, 79 (87%) clearly specified that SIS involved either cerebral edema or death after a concussion when a prior concussion had not resolved. Twelve articles (13%) could be interpreted as merely the events of two consecutive concussions...

Concussions are becoming increasingly important to manage properly as sports participation continues to rise. Repeated injuries occurring before the brain has had a chance to recover from an initial insult are particularly dangerous and must be prevented. Although much national media attention has been devoted to concussions in professional sports, it is important to appreciate that athletes in any age group, children and adolescents in particular, are at risk of sports-related concussion. It is crucial to remove an athlete from play any time concussion is suspected...

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...

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...
