Post-concussion syndrome has been related to axonal damage in patients with mild traumatic brain injury, but little is known about the consequences of injury on brain networks. In the present study, our aim was to characterize changes in functional brain networks following mild traumatic brain injury in patients with post-concussion syndrome using resting-state functional magnetic resonance ima...

In some individuals, return to normal function after a concussion occurs quickly and is easy to assess. In these individuals, neuropsychological testing is not necessary and adds little additional information to the clinical exam. In more difficult circumstances, such as a timely return to a contact or collision sport, or prolonged severe symptoms, additional information may be helpful to the c...

BACKGROUND Concussions remain a serious public health concern. It is important that persons involved in youth sports, particularly coaches, be made aware and educated on the signs and symptoms of concussion. This study assessed the perceptions of youth sport coaches who have received the Centers for Disease Control and Prevention's (CDC's) "Heads Up: Concussion in Youth Sports" materials in pre...

PRIMARY OBJECTIVE Balance disturbances occur in ∼30% of concussion injuries, with vestibular dysfunction reported as the main contributor. However, few have studied oculomotor control post-concussion to assess vestibular dysfunction. RESEARCH DESIGN The current research measured the differences in oculomotor control between athletes post-concussion (PC) and athletes without concussion (NC) du...

OBJECTIVE To evaluate symptoms and neurocognitive recovery patterns after sports-related concussion in high school and college athletes. STUDY DESIGN College athletes (n = 371) and high school athletes (n = 183) underwent baseline neuropsychological evaluation between 1997 and 2000. Individuals who received a concussion during athletic competition (n = 54) underwent serial neuropsychologic ev...

Concussion, or mild traumatic brain injury (mTBI), is a growing concern, especially among the pediatric population. By age 25, as many as 30% of the population are likely to have had a concussion. Many result in long-term disability, with some evolving to postconcussion syndrome. Treatments are being developed, but are difficult to assess given the lack of measures to quantitatively monitor con...

BACKGROUND Many professional sports have introduced sideline video review to help recognise concussions. The reliability and validity of identifying clinical and observable signs of concussion using video analysis has not been extensively explored. This study examined the reliability and validity of clinical signs of concussion using video analysis in the National Rugby League (NRL). METHODS ...

This article provides a review of current important issues in the management of athletes who have sustained a concussion during athletic competition. Recent research in the area of concussion management is reviewed with specific reference to the side line evaluation of concussion and the follow-up of the athlete during the recovery period. The use of neuropsychological testing in sports is also...

OBJECTIVE: To characterize the causes, effects, and risks associated with concussion in sports. BACKGROUND: Concussion is an injury associated with sports and is most often identified with boxing, football, ice hockey, and the martial arts. In addition, recent research has shown that concussion occurs in many different sports. In the decade of the 1990s, concussion became a primary issue for di...

F physicians, particularly those who work in emergency rooms or act as physicians for sports teams, are often confronted with concussion. Although concussion can result from a variety of everyday activities, this article will focus on sports-related concussion. When the injury happens, physicians must consider whether a player can resume play. If a player cannot resume play immediately, the iss...
