Summary: This systematic review and meta-analysis evaluated prevention strategies, unintended consequences, and modifiable risk factors for sport-related concussion (SRC) and/or head impact risk. The findings suggest that protective gear, policy and rule changes, training strategies, and SRC management strategies may help to prevent SRC. The study highlights the importance of further research on modifiable risk factors for informing effective concussion prevention strategies. Rating: 8/10.

Summary: The study aims to quantify and assess Head Impact Exposure (HIE) metrics among youth and collegiate football players. The study found that youth players experienced fewer impacts and lower impact magnitudes compared to collegiate players, with impacts during competition being more frequent and of greater magnitude than during practice at both levels.

Summary: This study evaluated the frequency and risk of same-year repeat concussions in the NFL, and found that the risk of repeat concussion was similar to that of a single concussion. Same-year repeat concussions also resulted in longer time missed compared to single or initial concussions.

Summary: The study found that most pediatric concussion patients undergoing early medical assessment and follow-up seem to achieve complete clinical recovery within 4 weeks, regardless of whether the concussion was sport-related or non-sport-related. Patients with higher initial symptom scores were more likely to have delayed physician-documented recovery. Additionally, greater material and social deprivation were associated with an increased risk of delayed recovery.

Summary: This study examines the factors associated with concussion management behavior in adult Ladies Gaelic Football players. The findings suggest that being diagnosed with a concussion greatly influences the subacute management behavior. It is recommended to improve access to medical personnel and introduce comprehensive concussion education to ensure proper medical care for players.

Summary: This study investigated plasma proteomic profiling to identify biomarkers related to return to sport (RTS) following sport-related concussion (SRC). Results showed that there were 87 dysregulated plasma proteins in concussed athletes with recovery >= 14-days, associated with the STAT3 pathway, regulation of the epithelial mesenchymal transition by growth factors pathway, and acute phase response signaling. These findings provide insights into the neurobiological recovery mechanism.

Summary: The study aimed to describe head impact biomechanics outcomes in youth flag football and explore factors associated with head impact magnitudes. Results showed relatively low head impact rates but relatively high linear and rotational acceleration magnitudes, with variations across seasons and age groups.

Summary: This study aims to validate the 4-factor model of the Post-Concussion Symptom Scale (PCSS) among adolescent student-athletes and provide normative reference data for each factor and the total score, stratified by gender and preexisting health conditions. The study confirms that gender, number of preexisting conditions, and mental health history are important factors to consider when interpreting PCSS symptom severity.

Summary: This study examines how the wording of questions can influence the reporting of traumatic brain injury (TBI). The results show that a greater percentage of respondents reported a lifetime history of concussion compared to mild TBI, suggesting that the terminology used can impact reporting.

Summary: Although acute effects of concussion and mild TBI are well understood, certainty regarding long-term outcomes in sports-related concussion is limited. Long-term deficits may include cognitive dysfunction, depression, and executive dysfunction, with a potential link to neurodegenerative diseases. The decision to return to play after recovery from injury and informed of potential risks should be the athlete's own choice.

Summary: The survey revealed areas of expert agreement and disagreement regarding the diagnosis of mild traumatic brain injury (TBI), suggesting that observable signs are more diagnostically important than subjective symptoms, with certain symptoms and test findings consistently rated as highly important for increasing the likelihood of a mild TBI diagnosis.

Summary: This study showed that a 12-week combined physical training program had a positive impact on executive function in adults with epilepsy, particularly in attention and language tasks. It is recommended that individuals with epilepsy actively participate in physical exercise to reduce the impact of the disease on cognitive function.

Summary: The IC-CoDE is a classification system for cognitive diagnostics in epilepsy research that produces definable and stable cognitive phenotypes. It has been applied in studies across multiple epilepsy centers and has consistently generated distributions of cognitive phenotypes.

Summary: No significant association was found between subjective cognition and objective measures of cognitive functioning among former collegiate football players. However, a greater self-reported concussion history was inversely associated with subjective cognition. Distress was significantly related to all subjective cognition metrics as well as performance on delayed recall and verbal fluency. Sleep quality was only significantly related to timed visuospatial sequencing.

Summary: This study aimed to evaluate subjective memory complaints in patients with epilepsy using the Memory Assessment Clinics Self-Rating Scale (MAC-S) and to create a shorter version - the Memory Assessment Clinics Scale for Epilepsy (MAC-E). Through various analyses, a five-factor structure was identified and the MAC-E was reduced from 49 to 30 items.
