PURPOSE: Young children have a high risk of concussion or mild traumatic brain injury (mTBI). Children often appear healthy soon after mTBI, but some have pervasive cognitive and/or motor impairments. Understanding underlying mechanisms recruited after concussion may help for return to play protocols and mitigating what might be lifelong impairments. METHODS: We investigated molecular and behavioral changes in a rat model of childhood concussion. Rats received an injury or sham procedure at an age approximately equivalent to the human period of early childhood...

Background: Return-to-play protocols describe stepwise, graduated recoveries for safe return from concussion; however, studies that comprehensively track return-to-play time are expensive to administer and heavily sampled from elite male contact-sport athletes. Purpose: To retrospectively assess probable recovery time for collegiate patients to return to play after concussion, especially for understudied populations, such as women and nonelite athletes. Study Design: Cohort study; Level of evidence, 3...

Common sports injuries include bone stress injuries (BSIs), anterior cruciate ligament (ACL) injuries, and concussions. Less commonly recognized are the specific sex differences in epidemiology, risk factors, and outcomes of these conditions by sex. An understanding of these factors can improve their clinical management, from prescribing appropriate prehabilitation to guiding postinjury rehabilitation and return to play. This narrative review summarizes the sex differences in the diagnosis and management of BSIs, ACL injuries, and concussions...

OBJECTIVE: Concussions can result in auditory processing deficits even in the absence of hearing loss. In children and adolescents, the extent to which these impairments have functional consequences for everyday listening, such as the ability to understand speech in noisy environments, is unknown. RESEARCH DESIGN: Case-control study. SUBJECTS AND METHODS: Forty youth comprised the participants: 20 had sustained a concussion and were recovering from their injury, and 20 controls had sustained non-concussive orthopaedic (e...

Sports concussions are recognized as significant injuries among young athletes. Research demonstrates that return-to-play prior to becoming asymptomatic has significant repercussions including sustained cognitive deficits. Many programs have begun to use computerized testing rather than traditional neuropsychological tests to (a) determine baseline performance, (b) track symptoms, and (c) measure symptoms following concussion. Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is one such tool...

BACKGROUND AND OBJECTIVES: Postconcussion syndrome (PCS) has been controversial for more than 150 years. As there have not been any surveys of PCS among neurologists in the United States since 1992, another was performed using most of the prior items to assess current opinions and practices and whether there have been any changes since 1992. METHODS: Two hundred and eighty-nine neurologists attending the Texas Neurological Society 20th Annual Winter Conference continuing medical education meeting in 2017 were supplied the survey instrument with registration materials...

Even in the presence of underreporting, sports-related concussions/mild traumatic brain injuries (mTBI) are on the rise. In the absence of proper diagnosis, an athlete may return to play prior to full recovery, increasing the risk of second-impact syndrome or protracted symptoms. Recent evidence has demonstrated that sub-concussive impacts, those sustained routinely in practice and competition, result in a quantifiable pathophysiological response and the accumulation of both concussive and sub-concussive impacts sustained over a lifetime of sports participation may lead to long-term neurological impairments and an increased risk of developing neurodegenerative diseases...

There is conflicting evidence regarding whether females are more adversely affected after concussion than males. Further, recent research suggests that hormonal contraceptive (HC) use may affect symptom severity and duration post-concussion. The objective of this study was to examine the effects of sex and HC use on outcomes following concussion among collegiate varsity athletes. We hypothesized that females would have longer length of recovery (LOR), and that peak symptom severity would be associated with longer LOR in both males and females...

OBJECTIVES: The incidence of sport-related concussion (SRC) continues to rise. Presentations of concussed athletes vary from subtle symptoms to notable signs. Between the 4th and 5th iterations of the Concussion in Sport Group (CISG) guidelines, concussive convulsions were removed as a modifying factor, but little evidence or discussion supported this change. While considerable research exists regarding post-traumatic epilepsy in moderate to severe traumatic brain injury, convulsions following SRC are relatively understudied...

Vestibular and oculomotor testing is emerging as a valuable assessment in sport-related concussion (SRC). However, their usefulness for tracking recovery and guiding return-to-play decisions remains unclear. Therefore the purpose of this study was to evaluate their clinical usefulness for tracking SRC recovery. Vestibular and oculomotor assessments were used to measure symptom provocation in an acute group (n=21) concussed≤10 days, prolonged symptoms group (n=10) concussed ≥16 days (median=84 days), healthy group (n=58) no concussions in >6 months...
