Summary: This study examines the association between the severity of acute concussion symptoms and the time taken to return to school and sports in NCAA Division III collegiate athletes. The findings show that athletes with a high burden of acute symptoms have a slower return to school and sports, while those with a low burden of symptoms have a faster return.

Summary: Poor sleep is common among collegiate student-athletes and may increase the risk of sport-related concussions (SRC) in the long term. Factors such as symptom reporting and neurocognitive performance at baseline are also associated with insufficient sleep. This study examines the implications of baseline insufficient sleep and its association with SRC risk.

Summary: The study identified prevalent negative, anxiety-related perceptions about concussions among collegiate athletes, with female athletes showing higher anxiety beliefs. Addressing these perceptions through evidence-based education and management initiatives is crucial for improving emotions surrounding concussions, particularly for female athletes in this population.

Summary: This study aimed to assess the odds and time of lower extremity musculoskeletal injury (LEMSKI) after concussion in US collegiate athletes. The results showed that there was no significant increase in the odds of LEMSKI after concussion, but higher odds of non-time loss (NTL) LEMSKI and lower odds of time loss (TL) LEMSKI were observed in football.

Summary: This study investigated gender differences in head impact rates in high school varsity soccer players over two seasons. Results showed that regardless of the calculation method used, males had higher head impact rates than females, with substantial variations in individual head impact exposure within a team.

Summary: The study found that previous concussions are associated with smaller hippocampal volumes and more severe subjective clinical symptoms in otherwise healthy athletes. The diagnostic criteria used to quantify previous concussions also play a significant role in these associations.

Summary: The study aimed to assess injury patterns in collegiate club quidditch athletes over three seasons. The overall injury incidence rate for quidditch injuries was 4.55 per 1000 athlete exposures. Male athletes had a higher injury rate compared to females, with the most common injuries being lower extremity injuries and sprains. The study identified areas for improvement in education, injury prevention, and athlete care, particularly in relation to concussions in quidditch.

Summary: Female athletes are more susceptible to sport-related concussions, especially in soccer. They experience more somatic symptoms such as headache, migraine, and sleep disturbance, and may require longer recovery time. The 6th ICSS does not extensively address sex differences, which are crucial for concussion management protocols in many sports.

Summary: A study on sports concussion assessments among college athletes found that there are some differences between females and males in symptom reporting and neurocognitive impairments. Although no sex-based differences were observed in most concussion assessment parameters, females showed significant differences in symptom provocation using the VOMS.

Summary: By studying videos of concussions in professional football games, Zimmerman et al. found that head impacts leading to loss of consciousness are associated with higher forces and deformation in brainstem regions involved in arousal. The biomechanical effect of impacts can be estimated using computational models of strain within the brain. This research aims to understand why similar head impacts produce distinct neurological effects.

Summary: This study described the epidemiology of spine injuries in NCAA wrestlers, finding that most injuries were new and athletes commonly returned to sport within 24 hours. The injury rate was higher in competition than in practice, and both the preseason and postseason had higher injury rates compared to the regular season.

Summary: The study aimed to test the hypothesis that individuals with a history of traumatic brain injury (TBI) before the collegiate pre-season are at a higher risk for re-injury. The findings revealed that collegiate athletes with a lifetime history of TBI had a significantly higher risk of sustaining a subsequent concussion.

Summary: The study found that Veterans with a history of mild traumatic brain injury showed higher intraindividual variability in executive functions compared to military controls, even after adjusting for PTSD symptoms. PTSD symptoms were significantly negatively correlated with the mean executive function performance, but not with intraindividual variability. Intraindividual variability in executive functions was negatively associated with the microstructure of white matter pathways connecting frontal and more posterior regions.

Summary: The study found differences in self-efficacy and coping style among combat-exposed Veterans with comorbid mTBI and PTSD, PTSD-only, and mTBI-only groups. The comorbid and PTSD-only groups generally had lower self-efficacy, while the PTSD-only group used less action-focused coping compared to the mTBI-only and control groups.

Summary: Previous research has shown a relationship between the APOE e4 allele and worse neurobehavioral functioning following MTBI. In the MTBI group, participants with the APOE e4 allele had significantly worse scores on various measures, and consistently had a higher number of elevated measures compared to other subgroups. The APOE e4 allele could potentially be used in screening tools to predict SMVs at risk for poor long-term neurobehavioral outcomes and provide early intervention.

Summary: The study examined neurobehavioral symptom reporting in military veterans and found significant associations between TBI diagnostic status and symptom etiology group with neurobehavioral symptoms. Specifically, the Comorbid and Behavioral Health groups generally reported greater symptoms. The findings highlight the importance of prioritizing integrated behavioral health interventions for this vulnerable population.

Summary: This study examined the impact of remote history of mild traumatic brain injury (mTBI) on health-related quality of life (HR-QOL) in Veterans, finding that mTBI contributes to poorer HR-QOL, especially in physical health and social functioning. Depression and neurobehavioral symptoms were consistent predictors of HR-QOL, with employment status and number of lifetime mTBIs also playing important roles in specific HR-QOL domains.

Summary: This study examined the interactive relationships between a common BDNF polymorphism (Val66Met) and biological sex on cognitive functioning in healthy adolescent athletes. The results showed that although there were no significant main effects for BDNF genotype and sex on cognitive functioning, there was a significant interaction between BDNF genotype and sex for visual-motor speed performance. Female Met carriers demonstrated better performance than male Met carriers, while there were no differences between females and males without a Met allele on visual-motor speed performance. These preliminary findings suggest that the Met allele may have some neuroprotective effects in healthy adolescent females.

Summary: This study examines sex differences in clinical and functional outcomes among military veterans with traumatic brain injury (TBI). The results show that males have a higher frequency of TBI diagnoses and are more likely to experience blast-related injuries and employment, while females are more likely to report falls, TBI since deployment, and more severe neurobehavioral symptoms. These findings emphasize the importance of including females in TBI research to enhance understanding of sex-specific experiences and improve targeted clinical care.

Summary: Subjective memory complaints in Veterans with histories of mild traumatic brain injury (mTBI) are associated with lower cortical thickness in right frontal and temporal regions, but not with objective memory performance. These subjective complaints may indicate underlying brain morphometry independently of objective cognitive testing.

Summary: The study aimed to examine clinical outcomes and employment status in Veterans with and without a dual diagnosis of traumatic brain injury (TBI) and spinal cord injury (SCI). The findings showed that Veterans with a history of TBI had poorer clinical outcomes, regardless of SCI status. However, the rates of unemployment were similarly high across all three groups.
