Background Previous studies have identified the effect of sport-related concussion on health-related quality of life through the use of patient-reported outcome measures. However, there has been little research exploring the underlying mechanisms that influence these perceptions of health-related quality of life among adolescent athletes who have sustained a sport-related concussion. Purpose ...

Sports-related concussions have unique features that distinguish them from those mild traumatic brain injuries (MTBI's) caused by other mechanisms. Sports-related MTBI's may result from relatively lower-velocity impacts as compared with high-speed motor vehicle collisions, and are thought to cause different neurophysiologic injury. A survey of youth coaches revealed 42% believed a concussion on...

CONTEXT Troops deployed to Iraq and Afghanistan are at high risk for exposure to combat events resulting in mild traumatic brain injury (MTBI) or concussion and posttraumatic stress disorder (PTSD). The longer-term impact of combat-related concussion/MTBI and comorbid PTSD on troops' health and well-being is unknown. OBJECTIVE To assess longitudinal associations between concussion/MTBI and PT...

The aim of this investigation was to examine the influence of pediatric sport-related concussion on brain and cognitive function. To do so, we used a between-participants design, measures of executive control, and event-related potentials (ERPs). The findings demonstrate that children with a history of concussion exhibit behavioral deficits in attention, working memory and impulse control, as w...

OBJECTIVE The primary aim was to assess experience and knowledge of adult concussion among international, professional and semiprofessional players, coaches, medical staff, and referees within Rugby Union. The secondary aim was to identify preferred education dissemination routes. DESIGN Questionnaires devised specifically for players, coaches, medical staff, and referees. SETTING AND PARTI...

The purpose of this study was to examine the effectiveness of an active rehabilitation intervention for adolescents who are slow-to-recover after a sport-related concussion. Ten adolescents (three girls and seven boys) seen at the Montreal Children's Hospital Concussion Clinic participated in this case series. Adolescents who were symptomatic more than 4 weeks after the injury were provided wit...

Sport-related concussion is a common injury that occurs in a variety of sports. In recent years, more attention has been focused on the importance of this injury as well as the long-term complications of unrecognized, repetitive, and/or severe injury. The acute presentation of concussion as well as the diagnosis of concussion is often straightforward and obvious, but it can also be subtle and d...

Recent studies have shown that the detrimental effects of sports concussions on cognitive and motor function may persist up to a few years post-injury. The present study sought to investigate the effects of having sustained a sports concussion more than 30 years prior to testing on cognitive and motor functions. Nineteen healthy former athletes, in late adulthood (mean age = 60.79; SD = 5.16), ...

OBJECTIVES To evaluate the efficacy of cognitive and physical rest for the treatment of concussion. STUDY DESIGN High school and collegiate athletes (N = 49) underwent post-concussion evaluations between April 2010 and September 2011 and were prescribed at least 1 week of cognitive and physical rest. Participants were assigned to groups on the basis of the time elapsed between sustaining a co...

Concussion from sport is increasingly recognized as a public health priority. In response, all states and the District of Columbia have enacted youth concussion legislation. This paper first examines key developments in concussion-related policy and legislation and then uses the findings from recent scientific studies to highlight the need to incorporate evolving scientific evidence into concus...
