Article Synopsis
  • * A study analyzed 174,878 student-athletes to assess the frequency of low scores on a concussion management test (ImPACT) for those with self-reported ADHD and/or LD, comparing them to a control group without these disorders.
  • * Results indicated that student-athletes with LD frequently scored low on the ImPACT (30-37%) and those with both ADHD and LD also showed significant low scoring rates (24-31%), highlighting the need for better understanding of these conditions in concussion assessments.

Article Synopsis
  • The review aimed to assess how much sport-related concussion research has incorporated social determinants of health (SDoH) and health equity, while offering suggestions for improvement.
  • Analysis of 31 studies (2,698 participants) revealed a lack of focus on race, ethnicity, and socioeconomic status in concussion research, with many studies excluding participants based on various demographic factors.
  • The updated consensus statement encourages researchers to include underrepresented groups in studies to better understand their specific needs and improve treatment effectiveness and adherence.

Valid performance on preseason baseline neurocognitive testing is essential for accurate comparison between preseason and post-concussion test results. Immediate Post-Concussion and Cognitive Testing (ImPACT) is commonly used to measure baseline neurocognitive function in athletes. We examined the prevalence of invalid performance on ImPACT baseline testing and identified correlates of invalid performance.

Graded exertion testing (GXT) is an important tool for concussion management, as it is used to personalize post-concussion exercise prescription and return athletes to sport. However, most GXT requires expensive equipment and in-person supervision. Our objective was to assess the safety and feasibility of the ntreal irtual xertion (MOVE) protocol, a no-equipment, virtually compatible GXT, in healthy children and children with subacute concussion.

Article Synopsis
  • The content analysis focused on how social determinants of health (SDoH) are represented in the CDC Guideline for diagnosing and managing mild traumatic brain injury in children.
  • Out of 37 studies reviewed, none explicitly mentioned SDoH, and only a small percentage tackled them as a central topic, with a focus on domains like Education Access and Quality, Social and Community Context, and Economic Stability.
  • The analysis found that SDoH were mainly viewed as predictors of outcomes rather than being integrated into diagnosis or treatment discussions, indicating their minimal role in shaping the Guideline.

Clinical recovery after sport-related concussion varies as a function of pre-injury and acute factors. Whether, or the extent to which, concussion history is associated with clinical outcome after sport-related concussion is uncertain, because research has produced mixed findings. The present study aimed to assess whether a history of previous concussions was associated with prolonged clinical recovery after a subsequent sport-related concussion.

Adolescents with ADHD have a greater lifetime history of concussion and experience concussion-like symptoms of a concussion, complicating concussion assessment and management. It is well established that individuals who experience greater acute symptoms following concussion are at risk for slower recovery and persistent symptoms. We examined whether youth with ADHD experience worse acute effects, within the first 72 h following concussion, compared to youth without ADHD.

We examined the association between the severity of acute concussion symptoms and time to return to school and to sports in adolescent student athletes. We hypothesized that there would be an association between the severity of acute symptoms experienced in the first 72 hours and functional recovery such that adolescents with the lowest burden of acute symptoms would have the fastest return to school and sports and those with the highest burden of symptoms would have the slowest return to school and sports. This injury surveillance cohort included 375 adolescent student athletes aged 14-19 years who sustained a sport-related concussion between 2014 and 2020.

Authoritative sources advise clinicians and parents that a history of prior concussion confers increased risk for worse outcome from a future concussion. However, the strength of the evidence supporting such pronouncements and thus the extent to which clinicians should incorporate this information into their care and management of pediatric concussion is unclear. This systematic review critically analyzed and synthesized the literature on the association between a history of prior concussion and prognosis/clinical outcome following a subsequent sport-related concussion among children and adolescents.
