Psychological resilience, emotional symptoms, and recovery duration in adolescent sport-related concussion.

OBJECTIVE: This study aimed to explore the relation between resilience, emotional changes following injury, and recovery duration in sport-related concussion. METHODS: Thirty-one high school student-athletes (ages 14-18) with sports-related injuries (concussion, n = 17 orthopedic injury, n = 14) were recruited from a pediatric sports medicine clinic. Participants completed self-report resilience ratings and self- and parent-reported post-concussion symptoms as part of a neuropsychological test battery. Hierarchical regression analyses examined predictors of recovery duration, including: (1) injury group and sex, (2) self- and parent-reported emotional symptom changes, and (3) resilience score. RESULTS: Injury group and sex alone were not predictors of recovery duration (p = .60). When parent and patient reported emotional response to injury were added to the analysis, 35% of the variance in length of recovery was explained, making the model statistically significant (F (2.26) = 3.57, p = .019). Including resilience did not reach statistical significance (p = .443). Post hoc analysis revealed parent-report of emotional changes was significantly associated with recovery duration t(31) = 3.16, p < .01), while self-report was not (p = .54). CONCLUSIONS: Parent-reported emotional change plays a pivotal role in predicting recovery length among adolescents recovering from sport-related concussion and orthopedic injury. These pilot findings highlight the significance of caregiver input in the clinical exam and emphasize the potential for acute interventions supporting psychological resources to enhance recovery outcomes across adolescent sport-related injuries.

Effects of Cumulative Head Impact Exposure in Adolescent Male Contact and Collision Sport Student Athletes.

OBJECTIVE: This prospective cohort study aimed to investigate the association between head impact exposure (HIE) and neuropsychological sequelae in high school football and ice hockey players over 1 year. SETTING: Community sample. PARTICIPANTS: A cohort of 52 adolescent American football and ice hockey players were enrolled in the study, with a final study sample of 35 included in analyses. DESIGN: The study followed a prospective cohort design, with participants undergoing neuropsychological screening and accelerometer-based measurement of HIE over 1 season. MAIN MEASURES: Changes in cognition, emotions, behavior, and reported symptoms were assessed using standardized neuropsychological tests and self-reported questionnaires. RESULTS: Cumulative HIE was not consistently associated with changes in cognition, emotions, behavior, or reported symptoms. However, it was linked to an isolated measure of processing speed, showing inconsistent results based on the type of HIE. History of previous concussion was associated with worsened verbal memory recognition (ImPACT Verbal Memory) but not on a more robust measure of verbal memory (California Verbal Learning Test [CVLT]). Reported attention-deficit/hyperactivity disorder history predicted improved neurocognitive change scores. No associations were found between reported history of anxiety/depression or headaches/migraines and neuropsychological change scores. CONCLUSION: Overall, our findings do not support the hypothesis that greater HIE is associated with an increase in neuropsychological sequelae over time in adolescent football and ice hockey players. The results align with the existing literature, indicating that HIE over 1 season of youth sports is not consistently associated with significant neuropsychological changes. However, the study is limited by a small sample size, attrition over time, and the absence of performance validity testing for neurocognitive measures. Future studies with larger and more diverse samples, longer follow-up, and integration of advanced imaging and biomarkers are needed to comprehensively understand the relationship between HIE and neurobehavioral outcomes. Findings can inform guidelines for safe youth participation in contact sports while promoting the associated health and psychosocial benefits.

Longitudinal Outcomes of Cumulative Impact Exposure on Oculomotor Functioning in Professional Motorsport Drivers.

Importance: Professional motorsport drivers are regularly exposed to biomechanical forces comparable with those experienced by contact and collision sport athletes, and little is known about the potential short-term and long-term neurologic sequelae. Objective: To determine whether cumulative impact exposure is associated with oculomotor functioning in motorsport drivers from the INDYCAR professional open-wheel automobile racing series. Design, Setting, and Participants: This is a longitudinal retrospective cohort study conducted across 3 racing seasons (2017-2019). Statistical analyses were conducted in November 2021. Data were retrieved from a secondary care setting associated with the INDYCAR series. INDYCAR series drivers who participated in 3 professional level racing seasons and were involved in at least 1 contact incident (ie, crash) in 2 of the 3 seasons were included in the study. Exposure: Cumulative acceleration and deceleration forces and total contact incidents (ie, crashes) measured via accident data recorder third generation chassis and ear accelerometers. Main Outcomes and Measures: Postseries oculomotor performance, including predictive saccades, vergence smooth pursuit, and optokinetic nystagmus, was measured annually with a head-mounted, clinical eye tracking system (Neurolign Dx 100). Results: Thirteen drivers (mean [SD] age, 29.36 [7.82] years; all men) sustained median resultant acceleration forces of 38.15 g (observed range, 12.01-93.05 g; 95% CI, 30.62-65.81 g) across 81 crashes. A 2-way multivariate analysis of variance did not reveal a statistically significant association between ear and chassis average resultant g forces, total number of contact incidents, and racing season assessed (F9,12 = 0.955; P = .54; Wilks Λ = 0.44). Conclusions and Relevance: In this cohort study of professional drivers from the INDYCAR series, there were no statistically significant associations among cumulative impact exposure, racing season assessed, and oculomotor performance. Longitudinal studies across racing seasons using multidimensional examination modalities (eg, neurocognitive testing, advanced imaging, biomarkers, and physical examination) are critical to understand potential neurological and neurobehavioral sequelae and long-term consequences of cumulative impact exposure.

Assessing Preseason Baseline Cognitive Functioning in High School Student Athletes: A "Hybrid" Approach.

OBJECTIVE: International consensus statements highlight the value of neuropsychological testing for sport-related concussion. Computerized measures are the most frequently administered assessments of pre-injury baseline and post-injury cognitive functioning, despite known measurement limitations. To our knowledge, no studies have explored the convergent validity of computerized Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) and traditional, well-validated paper and pencil (P&P) neuropsychological tests in high school student athletes. This study aimed to assess a "hybrid" adolescent test battery composed of ImPACT and P&P measures to determine the extent of shared variance among ImPACT and P&P tests to inform comprehensive yet streamlined assessment. METHOD: Participants included male and female high school student athletes in the Southeastern United States participating in American football, hockey, and soccer who completed a battery of ImPACT and P&P tests (N = 69). RESULTS: We performed principal component analysis with ProMax rotation to determine components of the hybrid battery that maximally accounted for observed variance of the data (Kaiser-Meyer-Olkin factor adequacy = 0.71). Our analysis revealed four independent factors (Verbal Learning and Memory, ImPACT Memory and Speed, Verbal Processing Speed/Executive Functions, and Nonverbal Processing Speed/Executive Functions) explaining 75% of the variance. CONCLUSIONS: Findings of this study in adolescent student athletes support those from the adult literature demonstrating the independence of ImPACT and P&P tests. Providers should be aware of limitations in using standalone ImPACT or P&P measures to evaluate cognitive functioning after concussion. If confirmed in a larger, clinical sample, our findings suggest that a hybrid battery of computerized and P&P measures provides a broad scope of adolescent cognitive functioning to better inform recovery decisions, including return to play after concussion.

Pediatric mTBI during the COVID-19 pandemic: considerations for evaluation and management.

The COVID-19 pandemic has changed healthcare utilization patterns and clinical practice, including pediatric mTBI evaluation and management. Providers treating pediatric mTBI, including neuropsychologists, have a unique role in evaluating and managing an already complex injury in the context of the COVID-19 pandemic with limited empirically based guidelines. In the present paper, we review usual, evidence-based pediatric mTBI care, highlight changes experienced by healthcare providers since the onset of the pandemic, and provide possible considerations and solutions. Three primary challenges to usual care are discussed, including changes to post-injury evaluation, management, and treatment of persistent symptoms. Changing patterns of healthcare utilization have created unique differences in mTBI identification and evaluation, including shifting injury frequency and mechanism, reluctance to seek healthcare, and increasing access to telemedicine. Typical injury management has been compromised by limited access to usual systems/activities (i.e., school, sports, social/leisure activities). Patients may be at higher risk for prolonged recovery due to pre-injury baseline elevations in acute and chronic stressors and reduced access to rehabilitative services targeting persistent symptoms. Considerations and solutions for addressing each of the three challenges are discussed. Neuropsychologists and other pediatric healthcare providers will need to continue to flexibly adapt to the changing needs of youth recovering from mTBI through the duration of the pandemic and beyond. Consistent with pre-pandemic consensus statements, neuropsychologists remain uniquely qualified to evaluate and manage mTBI and provide an increasingly integral role as members of multidisciplinary teams in the context of the global pandemic.Abbreviations: AAP: American Academy of Pediatrics; CDC: Centers for Disease Control and Prevention; COVID-19: coronavirus disease 19; ED: emergency department; mTBI: Mild traumatic brain injury.

Pediatric Teleneuropsychology: Feasibility and Recommendations.

OBJECTIVE: Teleneuropsychology (TeleNP) is a growing and promising practice within the telemedicine landscape that has been well established within the adult neuropsychology literature. This project aimed to demonstrate the feasibility of TeleNP in a pediatric clinical population and disseminate clinical decision-making procedures to guide best practices for pediatric TeleNP. METHOD: This project conducted during the 2019 coronavirus (COVID-19) pandemic reflects the largest clinical cohort to date of TeleNP in a pediatric population (N = 129). Data were gathered retrospectively from patients who were rescheduled from in-person assessment to TeleNP between March to June 2020. RESULTS: TeleNP was an accessible option for most patients and families, with no differences in demographic variables in patient appointment attendance, whether testing was conducted, and whether the patient was referred for face-to-face follow-up. Patients using laptops/desktops were more likely to undergo remote test administration in comparison with patients using phones/tablets (χ2 = 23.83, p < .002). Sixty-three percent of the sample were referred for a face-to-face follow-up assessment. CONCLUSIONS: TeleNP is feasible in a pediatric clinical population ranging to begin the process of differential diagnosis and treatment planning. Pediatric TeleNP may be most efficacious as a screening procedure due to limited measures suited for remote administration and behavioral challenges interfering with testing requiring in-person follow-up. TeleNP screening as standard practice for patients who do not require a full, traditional neuropsychological battery may provide a more efficient care model, with more patients able to be seen using shorter batteries with less wait time.

Applying an Evidence-Based Assessment Model to Identify Students at Risk for Perceived Academic Problems following Concussion.

OBJECTIVES: The aim of this study was to demonstrate the utility of an evidence-based assessment (EBA) model to establish a multimodal set of tools for identifying students at risk for perceived post-injury academic problems. METHODS: Participants included 142 students diagnosed with concussion (age: M=14.95; SD=1.80; 59% male), evaluated within 4 weeks of injury (median=16 days). Demographics, pre-injury history, self- and parent-report measures assessing symptom severity and executive functions, and cognitive test performance were examined as predictors of self-reported post-injury academic problems. RESULTS: Latent class analysis categorized participants into "high" (44%) and "low" (56%) levels of self-reported academic problems. Receiver operating characteristic analyses revealed significant discriminative validity for self- and parent-reported symptom severity and executive dysfunction and self-reported exertional response for identifying students reporting low versus high academic problems. Parent-reported symptom ratings [area under the receiver operating characteristic curve (AUC)=.79] and executive dysfunction (AUC=.74), and self-reported ratings of executive dysfunction (AUC=.84), symptoms (AUC=.80), and exertional response (AUC=.70) each classified students significantly better than chance (ps<.001). Hierarchical logistic regression indicated that, of the above, self-reported symptoms and executive dysfunction accounted for the most variance in the prediction of self-reported academic problems. CONCLUSIONS: Post-concussion symptom severity and executive dysfunction significantly predict perceived post-injury academic problems. EBA modeling identified the strongest set of predictors of academic challenges, offering an important perspective in the management of concussion by applying traditional strengths of neuropsychological assessment to clinical decision making.

Academic effects of concussion in children and adolescents.

OBJECTIVE: The aim of this work is to study the nature and extent of the adverse academic effects faced by students recovering from concussion. METHOD: A sample of 349 students ages 5 to 18 who sustained a concussion and their parents reported academic concerns and problems (eg, symptoms interfering, diminished academic skills) on a structured school questionnaire within 4 weeks of injury. Postconcussion symptoms were measured as a marker of injury severity. Results were examined based on recovery status (recovered or actively symptomatic) and level of schooling (elementary, middle, and high school). RESULTS: Actively symptomatic students and their parents reported higher levels of concern for the impact of concussion on school performance (P < .05) and more school-related problems (P < .001) than recovered peers and their parents. High school students who had not yet recovered reported significantly more adverse academic effects than their younger counterparts (P < .05). Greater severity of postconcussion symptoms was associated with more school-related problems and worse academic effects, regardless of time since injury (P < .001). CONCLUSIONS: This study provides initial evidence for a concussion's impact on academic learning and performance, with more adverse effects reported by students who had not yet recovered from the injury. School-based management with targeted recommendations informed by postinjury symptoms may mitigate adverse academic effects, reduce parent and student concerns for the impact of the injury on learning and scholastic performance, and lower the risk of prolonged recovery for students with active postconcussion symptoms.

An open-label trial of duloxetine in patients with irritable bowel syndrome and comorbid generalized anxiety disorder.

OBJECTIVE: Irritable bowel syndrome (IBS) is commonly comorbid with generalized anxiety disorder (GAD). We evaluated whether duloxetine would lead to improvement in symptoms and quality of life in patients with both conditions. METHOD: A 12-week, open-label trial of duloxetine was conducted in 13 subjects with IBS and GAD. The primary outcome measure was the Clinical Global Impression (CGI) Scale. Secondary measures included the Hamilton Anxiety Rating Scale, IBS Quality of Life (IBS-QOL) Scale, and IBS Symptom Severity Scale (IBS-SSS). RESULTS: Repeated measures ANOVA was used to examine the effect of treatment with duloxetine on ratings of anxiety and IBS. Significant improvement was observed on the CGI-Improvement (F = 14.19, df = 1,12, p < 0.001) and Severity scales (F = 16.16, df = 1,12, p < 0.001). Secondary measures revealed significant reduction in symptoms of anxiety (F = 11.66, df = 1,12, p < 0.01), ηp(2) = 0.56, and IBS-SSS (F = 6.05, df = 1,12, p < 0.001), ηp(2) = 0.34, in addition to IBS-QOL improvements (F = 11.66, df = 1,12, p < 0.01), ηp(2) = 0.56. CONCLUSION: Results of this pilot study support the efficacious use of duloxetine in comorbid IBS and GAD. Participants reported significant reductions in IBS components, as well as improvement in GAD.

Interpersonal interactions on online forums addressing eating concerns.

OBJECTIVE: Although some research suggests that online eating disorder forums promote "pro-eating-disorder" lifestyles and discourage recovery, other research suggests that such forums are an important source of interpersonal support. The current study extends this research by exploring the positive and negative behaviors encouraged on these forums and by comparing forum members' perceptions of support received from online and offline relationships to support received in relationships of age-matched controls. METHOD: In a survey of 60 forum members, we assessed information exchanged and support provided on eating disorder forums. Further, we assessed perceptions of social support for general and specific life concerns in this group of forum members as well as 64 age-matched university controls. RESULTS: Results show that both adaptive and maladaptive behaviors are encouraged on the forums, and that this encouragement has some influence on forum members trying out these behaviors. Overall, forum members reported receiving less support for their eating concerns as compared to their general life stressors, and they perceived less support for both their general concerns and eating concerns in their offline relationships as compared to their online forum relationships. Moreover, forum members reported receiving less support from their offline relationships as compared to support received in relationships by age-matched controls. DISCUSSION: Forum members perceive less support in their important relationships than other peers do, and they seek out and participate in forums as a means of attaining greater social support. However, our research suggests that these forums also encourage dysregulated eating behaviors. Implications of online forum support and its impact on recovery are discussed further.
