RESUMEN
Mild traumatic brain injury (mTBI) is a known risk factor for neurodegenerative diseases, yet the precise pathophysiological mechanisms remain poorly understand, often obscured by group-level analysis in non-invasive neuroimaging studies. Individual-based method is critical to exploring heterogeneity in mTBI. We recruited 80 mTBI patients and 40 matched healthy controls, obtaining high-resolution structural MRI for constructing Individual Differential Structural Covariance Networks (IDSCN). Comparisons were conducted at both the individual and group levels. Connectome-based Predictive Modeling (CPM) was applied to predict cognitive performance based on whole-brain connectivity. During the acute stage of mTBI, patients exhibited significant heterogeneity in the count and direction of altered edges, obscured by group-level analysis. In the chronic stage, the number of altered edges decreased and became more consistent, aligning with clinical observations of acute cognitive impairment and gradual improvement. Subgroup analysis based on loss of consciousness/post-traumatic amnesia revealed distinct patterns of alterations. The temporal lobe, particularly regions related to the limbic system, significantly predicted cognitive function from acute to chronic stage. The use of IDSCN and CPM has provided valuable individual-level insights, reconciling discrepancies from previous studies. Additionally, the limbic system may be an appropriate target for future intervention efforts.

INTRODUCTION: Mild traumatic brain injury (mTBI) or concussion is prevalent among trauma patients, but symptoms vary. Assessing discharge safety is not standardized. At our institution, occupational therapy (OT) performs cognitive assessments for mTBI to determine discharge readiness, potentially increasing resource utilization. We aimed to describe characteristics and outcomes in mTBI trauma patients and hypothesized that OT consultation was associated with increased length of stay (LOS). METHODS: This is a retrospective study at a level 1 trauma center over 17 mo. All patients with mTBI, without significant concomitant injuries, were included. We collected data regarding OT assessment, LOS, mechanism of injury, Glasgow coma score, injury severity score (ISS), concussion symptoms, and patient disposition. Statistical analysis was performed, and significance was determined when P < 0.05. RESULTS: Two hundred thirty three patients were included. Median LOS was 1 d and ISS 5. Ninety percent were discharged home. The most common presenting symptom was loss of consciousness (85%). No symptoms were associated with differences in LOS or discharge disposition (P > 0.05). OT consult (n = 114, 49%) was associated with longer LOS and higher ISS (P < 0.01). Representation with concussive symptoms, discharge disposition, mechanism of injury, and patient demographics were no different regardless of OT consultation (P > 0.05). CONCLUSIONS: mTBI is common and assessment for discharge safety is not standardized. OT cognitive assessment was associated with longer LOS and higher injury severity. Despite institutional culture, OT consultation was variable and not associated with improved concussion-related outcomes. Our data suggest that OT is not required for mTBI discharge readiness assessment. To improve resource utilization, more selective OT consultation should be considered. Further prospective data are needed to identify which patients would most benefit.

OBJECTIVE: To assess psychosocial treatment preferences and factors that may affect treatment participation among young adults with a recent concussion and co-occurring anxiety. DESIGN: In-depth, semi-structured individual qualitative interviews, followed by thematic analysis using a hybrid deductive-inductive approach. SETTING: Academic medical center in the US Northeast. PARTICIPANTS: Seventeen young adults (18-24y) who sustained a concussion within the past 3-10 weeks and reported at least mild anxiety (≥5 on the Generalized Anxiety Disorder-7 questionnaire). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Primary outcomes include preferences for program content (eg, topics and skills), delivery modality, format, and barriers and facilitators to participation. RESULTS: We identified 4 domains characterizing participants' perceptions of and preferences for treatment. (1) Program content: Participants preferred a program early after injury that included psychoeducation and coping skills (eg, activity pacing, deep breathing, mindfulness). (2) Therapeutic processes: Participants preferred a person-centered approach in which clinicians normalized anxiety postconcussion and reassured them of recovery. (3) Program logistics: Participants endorsed that a brief, virtual program would be acceptable. They preferred access to program components through multiple modalities (eg, audio, video) and accommodations to manage concussion symptoms. (4) Barriers and facilitators to participation: Barriers included acute concussion symptoms (eg, screen sensitivity), time constraints, and forgetting sessions. Facilitators included a program that is flexible (format, scheduling), personalized (self-chosen mode for reminders, measure of accountability), and accessible (ie, advertising through health care professionals or social media). CONCLUSIONS: Participants need psychosocial support that normalizes their experiences and provides education and coping tools. Treatments should be accessible, flexible, and person centered. Psychosocial treatments meeting these preferences may help optimize the recovery of young adults with recent concussion and anxiety.

OBJECTIVE: The Common Sense Model (CSM) describes cognitive, emotional, and psychosocial factors that influence how health threats are processed and subsequently inform health-related decisions or actions. The purpose of this study was to examine psychosocial factors influencing coherence, or usefulness, of mild traumatic brain injury (mTBI) representations and their relationship to health-related decisions and actions. SETTING: Public university. PARTICIPANTS: There were 458 graduate and undergraduate college students who participated in a web-based survey (mean age = 22 years; SD = 3.6). DESIGN: A mixed-methods design randomized participants into 2 groups to examine perceptions of mTBI across differing injury mechanisms, or causes, by comparing actions recommended to a friend (Other; n = 214) with those generated for self (Self; n = 244). MAIN MEASURES: Seven common injury mechanisms representative of university student mTBI experiences were presented as vignettes (cause). Each vignette included open- and closed-ended questions framed from CSM constructs (identity, consequences, action plans, timeline, and social context). Data were analyzed using a series of chi-square tests and multiple analysis of variance. Post hoc analysis identified differences in the injury vignettes. RESULTS: Students were more likely to identify the injury as mTBI ( = 8.62, P = .035) and recommend immediate healthcare (F1,415 = 316.89, P < .001) for all causes if the injury occurred to a friend as compared with themselves. Action plans also varied by cause, with post hoc analysis revealing a higher likelihood of healthcare seeking for motor vehicle crashes and assault and a lower likelihood for falls while intoxicated. Students were generally more likely to talk to closest confidants than doctors (F8,398 = 33.66, P < .001). CONCLUSION: Cause appears to be a key construct in generating illness representations and associated action plans for seeking care, with lower perceived severity causes (eg, falls) resulting in little to no health-seeking action. In addition, social support appears to be important for college students when making decisions about their health.

OBJECTIVE: Psychological symptoms following a sport-related concussion may affect recovery in adolescent athletes. Therefore, the aims of this study were to 1) describe the proportion of athletes with acute psychological symptoms, 2) identify potential predictors of higher initial psychological symptoms, and 3) determine whether psychological symptoms affect recovery in a cohort of concussed high school athletes. METHODS: A retrospective cohort study of high school athletes (14-18 years of age) who sustained a sport-related concussion from November 2017 to April 2022 and presented to a multidisciplinary concussion center was performed. The main independent variable was psychological symptom cluster score, calculated by summing the four affective symptoms on the initial Post-Concussion Symptom Scale (PCSS) (i.e., irritability, sadness, nervousness, feeling more emotional). The psychological symptom ratio was defined as the ratio of the psychological symptom cluster score divided by the total initial PCSS score. The outcomes included time to return to learn (RTL), symptom resolution, and time to return to play (RTP). Univariable and multivariable regressions were performed to adjust for demographic factors and health history. RESULTS: A total of 431 athletes (58.0% female, mean age 16.2 ± 1.3 years) were included. Nearly half of the sample (45%) reported at least one psychological symptom, with a mean psychological symptom cluster score of 4.2 ± 5.2 and psychological symptom cluster ratio of 0.10 ± 0.11. Irritability was the most commonly endorsed psychological symptom (38.1%), followed by feeling more emotional (30.2%), nervousness (25.3%), and sadness (22.0%). Multivariable regression showed that female sex (B = 2.15, 95% CI 0.91-3.39; p < 0.001), loss of consciousness (B = 1.91, 95% CI 0.11-3.72; p = 0.037), retrograde/anterograde amnesia (B = 1.66, 95% CI 0.20-3.11; p = 0.026), and psychological history (B = 2.96, 95% CI 1.25-4.70; p < 0.001) predicted an increased psychological symptom cluster score. Female sex (B = 0.03, 95% CI 0.00-0.06; p = 0.031) and psychological history (B = 0.06, 95% CI 0.02-0.10; p = 0.002) predicted an increased psychological symptom ratio. Multivariable linear regression showed that both higher psychological symptom cluster score and ratio were associated with longer times to RTL, symptom resolution, and RTP. CONCLUSIONS: In a cohort of high school athletes, 45% reported at least one psychological symptom, with irritability being most common. Female sex, loss of consciousness, amnesia, and a psychological history were significantly associated with an increased psychological symptom cluster score. Higher psychological symptom cluster score and psychological symptom ratio independently predicted longer recovery. These results reinforce the notion that psychological symptoms after concussion are common and may negatively impact recovery.

PRIMARY OBJECTIVE: It is unclear of the correlation between a mild traumatic brain injury (mTBI) and repeated subconcussive (RSC) impacts with respect to injury biomechanics. Thus, the present study was designed to determine the behavioral and histological differences between a single mTBI impact and RSC impacts with subdivided cumulative kinetic energies of the single mTBI impact. RESEARCH DESIGN: Adult male Sprague-Dawley rats were randomly assigned to a single mTBI impact, RSC impact, sham, or repeated sham groups. METHODS AND PROCEDURES: Following a weight drop injury, anxiety-like behavior and general locomotive activity and were assessed using the open field test, while motor coordination was evaluated using a rotarod unit. Neuronal loss, astrogliosis, and microgliosis were assessed using NeuN, GFAP and Iba-1 immunohistochemistry. All assessments were undertaken at 3- and 7-days post impact. MAIN OUTCOMES AND RESULTS: No behavioral disturbances were observed in injury groups, however, both injury groups did lead to microgliosis following 3-days post-impact. CONCLUSIONS: No pathophysiological differences were observed between a single mTBI impact and RSC impacts of the same energy input. Even though a cumulative injury threshold for RSC impacts was not determined, a threshold still may exist where no pathodynamic shift occurs.

OBJECTIVE: To identify differential trajectories of neurocognitive outcomes following pediatric concussion and investigate predictors associated with patterns of recovery up to 3 months. METHODS: 74 participants aged 8-17 years completed attention/working memory, processing speed, and executive function measures at 2 weeks, 1 month, and 3 months post-injury. We used principal component analysis to generate a composite of information processing. Group-based trajectory modeling identified latent trajectories. Multinominal logistic regression was used to examine associations between risk factors and trajectory groups. RESULTS: We identified three trajectories of neurocognitive outcomes. The medium (54.6%) and high improving groups (35.8%) showed ongoing increase in information processing, while the low persistent group showed limited change 3 months post-injury. This group recorded below average scores on Digit Span Forward and Backward at 3 months. History of pre-injury headache was significantly associated with the persistent low scoring group, relative to the medium improving (p = 0.03) but not the high improving group (p = 0.09). CONCLUSIONS: This study indicates variability in neurocognitive outcomes according to three differential trajectories, with groups partially distinguished by preexisting child factors (history of frequent headaches). Modelling that accounts for heterogeneity in individual outcomes is essential to identify clinically meaningful indices that are indicative of children requiring intervention.

OBJECTIVE: Following mild traumatic brain injury (mTBI), children show reduced processing speed (PS). Evidence suggests that slowed PS after TBI is associated with working memory deficits. Our aim was to investigate several forms of PS and to examine its impact on working and episodic memory performance in children after mTBI. METHOD: We included data of 64 children after mTBI and 57 healthy control children aged 8-16 years. PS (Color Naming, Coding, Symbol Search, Alertness) was compared between groups 1 week (T1) and 3-6 months (T2) after the injury; working and episodic memory outcome was compared between groups at T2. RESULTS: Alertness at T1 and Color Naming at T1 and T2 were significantly reduced following mTBI compared to controls, although most group differences in PS disappeared when patients with previous impairments and mTBI were excluded. PS was predictive for episodic and working memory performance 3-6 months after injury, whereas group was a significant predictor of working memory. CONCLUSIONS: Compared to healthy controls, children after mTBI showed reduced performance in verbal PS, which was associated with working memory. In children who are symptomatic after mTBI, diagnostic screening of PS could be helpful in identifying patients that could profit from speed-improving strategies.

BACKGROUND: We investigated the extent of literature and findings on relationships between vestibular issues, noise sensitivity (NS), and anxiety. We were interested in how relationships among these factors impacted adults' recovery three months or more after mild traumatic brain injury (mTBI). METHODS: We conducted a scoping review to evaluate the extent of evidence linking relationships between vestibular issues, NS and anxiety with recovery after mTBI. Data relating to study characteristics and key findings were extracted and used to inform a critical narrative synthesis of findings. RESULTS: After screening and full-text review, we included two studies. Both studies considered the combination of vestibular issues, NS and anxiety and mTBI recovery. Vestibular issues, NS and anxiety were all significantly associated with one another and their presence was the strongest indicator that symptoms would extend beyond three-months after mTBI. CONCLUSION: Few studies have focused on the relationships that vestibular issues, NS and anxiety have with one another and recovery after mTBI. Given the apparent strong relationships between these factors and prolonged recovery, we highlight this as an area warranting further investigation.
Vestibular issues, noise sensitivity and anxiety all appear to impact on recovery from mild traumatic brain injury.There appear to be quite strong relationships between vestibular, noise sensitivity and anxiety symptoms following mild traumatic brain injury.More work exploring these key symptoms and how they impact recovery from mild traumatic brain injury using a wide range of study methods and approaches are needed to advance the field.

OBJECTIVE: Evaluate the independent effect of age on baseline neurocognitive performance. STUDY DESIGN: Baseline ImPACT scores from tests taken by 7454 athletes aged 12-22 from 2009 to 2019 were split into three age cohorts: 12-14 years (3244), 15-17 years (3732), and 18-22 years (477). Linear regression analyses were used to evaluate the effect of age on ImPACT composite scores while controlling for demographic differences, medication-use, and symptom burden. Significance values have been set at p < 0.05. RESULTS: Linear regression analyses demonstrated that increased age does not significantly affect symptom score (ß = 0.06, p = 0.54) but does improve impulse control (ß = -0.45, p < 0.0001), verbal memory (ß = 0.23, p = 0.03), visualmotor (ß = 0.77, p < 0.0001), and reaction time (ß = -0.008, p < 0.0001) scores. However, age did not have an effect on visual memory scores (ß = -0.25, p = 0.07). CONCLUSIONS: Age was shown to be an independent modifier of impulse control, verbal memory, visual motor, and reaction time scores but not visual memory or symptom scores. This underscores the previous literature showing developmental differences as age increases among the adolescent athlete population. This data also indicates the need for repeat neurocognitive baseline testing every other year as baseline scoring is likely to change as athletes become older.

INTRODUCTION: In adolescent and collegiate athletes with sport-related concussion (SRC), we sought to evaluate the prevalence and predictors of long-term psychological symptoms. METHODS: A cohort study was conducted of athletes 12-24-year-old diagnosed with SRC between November 2017 and April 2022. Athletes/proxies were interviewed on psychological symptoms (i.e. anger, anxiety, depression, and stress). Participants who scored ≥75th percentile on one or more PROMIS (Patient-Reported Outcomes Measurement System) measures were operationalized to have subclinical, long-term psychological symptoms. Uni/multivariable regressions were used. RESULTS: Of 96 participants (60.4% male), the average age was 16.6 ± 2.6 years. The median time from concussion to interview was 286 days (IQR: 247-420). A total of 36.5% athletes demonstrated subclinical, long-term psychological symptoms. Univariate logistic regression revealed significant predictors of these symptoms: history of psychiatric disorder (OR = 7.42 95% CI 1.37,40.09), substance use (OR = 4.65 95% CI 1.15,18.81), new medical diagnosis since concussion (OR = 3.43 95% CI 1.27,9.26), amnesia (OR = 3.42 95% CI 1.02,11.41), other orthopedic injuries since concussion (OR = 3.11 95% CI 1.18,8.21), age (OR = 1.24 95% CI 1.03,1.48), days to return-to-play (OR = 1.02 95% CI 1.00,1.03), and psychiatric medication use (OR = 0.19 95% CI 0.05,0.74). Multivariable model revealed significant predictors: orthopedic injuries (OR = 5.17 95% CI 1.12,24.00) and return-to-play (OR = 1.02 95% CI 1.00,1.04). CONCLUSIONS: Approximately one in three athletes endorsed long-term psychological symptoms. Predictors of these symptoms included orthopedic injuries and delayed RTP.

OBJECTIVE: Considering that diagnostic decisions about mTBI are often predicated on clinical symptom criteria, it is imperative to determine which initial presentation features of mTBI have prognostic significance for identifying those at high risk for long-term functional impairment. SETTING: Zoom interview Participants: Male, former NCAA Division I, and professional-level National Football League (NFL) athletes (n = 177) between the ages of 27 and 85 (M = 54.1, SD = 14.7). DESIGN: Cross-sectional case-control. Main Measures: History of mild TBI, history of loss of consciousness (LOC), depression symptoms, insomnia, neurobehavioral symptoms. RESULTS: Number of mTBI exposures did not predict neurobehavioral symptoms (B = 0.21, SE = 0.18, p = 0.23), but number of mTBI + LOC events did (B = 2.27, SE = 0.64, p = <.001). Further analysis revealed that the number of mTBI + LOC events predicted neurobehavioral symptoms indirectly through both depression (B = 0.85, 95% CI = [0.27, 1.52) and insomnia (B = 0.81, 95% CI = [0.3, 1.4]). Further, the direct effect of mTBI + LOC events on neurobehavioral symptoms became non-significant when depression and insomnia were added to the model (B = 0.78, SE = 0.45, p = 0.08). CONCLUSIONS: Findings support LOC at time of injury as an important predictor of long-term outcomes. Additionally, results suggest depression and insomnia as potential mediators in the association between mTBI + LOC and neurobehavioral symptoms. These findings provide justification for early depression and insomnia symptom monitoring following mTBI + LOC.

OBJECTIVE: Persistent symptoms post-mild traumatic brain injury (mTBI) includes autonomic dysregulation (AD). The composite autonomic symptoms score, (COMPASS-31), was developed to quantify AD symptom severity in the last year, which limits clinical utility. The primary aim was to determine validity of a modified-COMPASS-31 measuring symptoms in the last month compared to the original, secondarily to compare both original and modified versions to the Neurobehavioral Symptom Inventory (NSI), and tertiarily to detect change post-treatment of the modified-COMPASS-31 compared to NSI and headache intensity (HI). PARTICIPANTS: Thirty-three military personnel with persistent headache post-mTBI. MAIN OUTCOME MEASURES: Total and domain scores for COMPASS-31 (original vs. modified) NSI and HI at baseline. Change in modified-COMPASS-31. NSI, and HI. RESULTS: Baseline COMPASS-31 versions were comparable and highly correlated (r = 0.72, p < 0.001), they were moderately correlated at best to the NSI (r < 0.6), which may suggest differences in measurement metrics. The mean change in modified-COMPASS-31 scores (15.4/100, effect size 0.8) was mild to moderately correlated to the change in HI (r = 0.39) score, but not to NSI (r = 0.28). CONCLUSION: The modified-COMPASS-31 appears to be valid, can measure change of AD symptom severity, and is recommended as an outcome measure.

OBJECTIVE: Older adults (OA) after mild traumatic brain injury (mTBI) have a high risk of developing persistent post-injury cognitive impairments. Lower pre-morbid cognitive reserve (CR) is increasingly investigated as a risk factor for cognitive dysfunction in OA. However, how CR protects against effects of mTBI at the brain level remains largely understudied. METHODS: We examined 22 OA who sustained mTBI (mean 67.69 years, SD 5.11) in the sub-acute phase and 15 age- and CR-matched healthy OA (mean 68 years, SD 5.55) performing a three-level visual N-back task using electroencephalography. We calculated inverse efficiency scores of performance from accuracy and reaction times. Event-related potentials served as neurocognitive correlates of attentional (P2) and working memory (P3) processing. RESULTS: Overall, mTBI OA performed worse than healthy OA (p = 0.031). Lower CR generally decreased performance (p < 0.001). Furthermore, with increasing task difficulty, task performance was more affected by CR (p = 0.004). At the brain level, P2 amplitude was lower in mTBI OA than in healthy OA (p = 0.05). There was no clear effect of CR on P2 or P3 measures. CONCLUSION: As mTBI OA with lower CR performed worse on a working-memory task, lower CR may be a risk factor for worse recovery after mTBI in this group.

BACKGROUND: Population-based data regarding the associations between prior concussion or brain injury symptoms/diagnosis and mental/social well-being is lacking for U.S. children. METHODS: Associations between prior concussion or brain injury symptoms/diagnosis (reported by parents of children ages 5-17 from the 2020 National Health Interview Survey) and current mental/social well-being were determined in multivariable models. RESULTS: Amongst 2020 US children, 8.7% and 5.3% had previous symptoms and diagnosis of concussion/brain injury, respectively. 23% of children with symptoms were never checked for a concussion/brain injury, with younger children at higher risk of not getting checked after symptomatic head trauma. Prior concussion or brain injury symptoms/diagnosis was associated with a higher likelihood of current depressive symptoms (odds ratio [OR] = 1.60; 95% CI = 1.21-2.14; p < 0.001), anxiety (OR = 2.07; 95% CI = 1.52-2.82; p < 0.001), difficulty making friends (OR = 1.57; 95% = 1.06-2.33; p = 0.03), use of medications for mental/social/behavioral issues (OR = 1.69; CI = 1.21-2.36; p = 0.002), and mental health therapy/counseling (OR = 1.52; 95% CI = 1.13-2.04; p = 0.006). CONCLUSION: U.S. children with prior concussion or brain injury symptoms/diagnosis have a higher rate of mental and social disturbances and a more frequent need for mental health services. Nearly one-quarter of children with significant symptoms after head trauma are never checked for a concussion/brain injury; routine concussion evaluation after head trauma should be emphasized especially in younger children.

OBJECTIVE: This study examined associations between Sport Concussion Assessment Tool-5 (SCAT-5) symptom reporting and gold-standard measures of anxiety and depression, and explored the utility SCAT-5 symptom subscales to identify anxiety and depression symptomology. DESIGN: Prospective cross-sectional study. SETTING: York University in Toronto, Canada. PARTICIPANTS: Preseason data were collected for varsity athletes (N = 296) aged between 17 and 25 years ( M = 20.01 years, SD = 1.69 years; 52% male). MAIN OUTCOME MEASURES: The SCAT-5 symptom evaluation scale was used to assess baseline symptoms. The Generalized Anxiety Disorder Index-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) were used to assess symptoms of anxiety and depression, respectively. RESULTS: Endorsement of SCAT-5 symptoms of feeling anxious, sadness, irritability, and feeling more emotional had the strongest correlations with the GAD-7 ( r' s > 0.400; P' s < 0.001). Sadness, trouble falling asleep, concentration problems, feeling slowed down, anxious, irritability, mental fog, fatigue, and memory problems had the highest correlations with the PHQ-9 ( r' s >0 .400; P' s < 0.001). The Emotional subscale from the SCAT-5 predicted mild to severe anxiety on the GAD-7 ( P < 0.001). The Sleep, Cognitive, and Emotional subscales predicted mild to severe depression on the PHQ-9 ( P' s < 0.05). CONCLUSIONS: These findings provide better delineation of symptoms endorsed on the SCAT-5 symptoms that aid in identification of athletes with symptoms of anxiety or depression who may be at risk for developing a clinical disorder or experiencing persistent symptoms after a concussion.

INTRODUCTION: Concussion symptoms following a traumatic accident are both common and known to adversely affect mental health and recovery in patients with traumatic brain injury. Depression, highly prevalent among patients with traumatic brain injury, is also associated with the important factors of sleep quality and resilience. However, the mediator and moderator roles of depression following concussion in patients with traumatic brain injury have been underexplored. The aims of this study were to investigate the mediating role of sleep quality in the relation between concussion symptoms and depression and to examine the moderating effect of resilience on this mediated model. DESIGN: Cross-sectional pretest data analysis of a randomized controlled trial. METHODS: A total of 249 adult patients with mild traumatic brain injury (Glasgow Coma Scale 13-15) at admission following brain injury were surveyed at a medical center in Taipei, Taiwan. The outcome variables were concussion symptoms (Rivermead Post-Concussion Symptom Questionnaire), sleep quality (Pittsburgh Sleep Quality Index), resilience (Resilience Scale for Adults), and depression (Beck Depression Inventory II). These data were analyzed using moderated mediation regressions with the SPSS PROCESS macro. RESULTS: In patients with mild traumatic brain injury, there was a significant positive relation between concussion symptoms and depression, of which sleep quality was a significant mediator. Additionally, resilience had a negative moderating effect on the relations between sleep quality and depression. Patients with less resilience showed a stronger negative effect of sleep quality on depression. CONCLUSION: Our findings suggest that ameliorating both concussion symptoms and sleep disturbance is important for reducing the risk of depression in patients with mild traumatic brain injury, especially in those patients with less resilience. CLINICAL RELEVANCE: It is essential for clinical nurses to develop interventions for patients with mild traumatic brain injury that will improve their sleep quality, while strengthening their resilience, to alleviate depression.

AIM: The primary aim of this study was to conduct an open pilot clinical trial of a brief mindfulness-based intervention for persistent postconcussion symptoms that occur after mild traumatic brain injury in military service members. For many service members, operational tempo and other time constraints may prevent them from completing a standard mindfulness-based stress reduction course. Thus, this study sought to examine the effectiveness of a five-session intervention called mindfulness-based stress, pain, emotion, and attention regulation (MSPEAR). METHODS: Participants were active duty service members with a history of mild traumatic brain injury (TBI) and persisting postconcussion symptoms, all of whom were recruited from an outpatient TBI rehabilitation program at a military treatment facility. Of the 38 service members that were initially enrolled, 25 completed the 5-session MSPEAR intervention, and 20 returned for a 5-week follow-up evaluation. Questionnaires assessing perceived stress, positive affect, pain interference and catastrophizing, sleep disturbances, perceived behavioral and attention regulation, self-efficacy and satisfaction with life were administered at preintervention, postintervention, and at 5-week follow-up intervals. Neuropsychological testing at preintervention and 5-week follow-up included performance validity measures, attention, working memory, and executive function measures. T-tests were run to compare for questionnaire measures at preintervention (Time 1) to postintervention (Time 2). Repeated analysis of variances were conducted to compare questionnaire and neuropsychological measures at Time 1, Time 2, and at Time 3 which is the 5-week follow-up. RESULTS: Improvements in perceived stress, positive affect, behavioral regulation, metacognition, sleep disturbance, self-efficacy, and satisfaction with life were found immediately after the MSPEAR intervention and were maintained at the 5-week follow-up. Magnification and helplessness aspects of pain catastrophizing improved when comparing preintervention to the 5-week follow-up. Pain interference was not significantly different across study assessment times. Neuropsychological testing revealed improvements in sustained attention, working memory, cognitive flexibility, and inhibitory control when comparing preintervention to the 5-week follow-up assessment. CONCLUSIONS: The MSPEAR intervention appears to show promise as a brief and effective therapy for specific postconcussion symptoms after mild traumatic brain injury in military service members. Each of the components of MSPEAR including stress, pain catastrophizing, emotion and attention regulation showed improvements in this study, and bears further investigation in a larger scale, preferably randomized controlled trial in those active duty military service members who experience persisting symptoms after a mild traumatic brain injury.

AIM: This study was designed to explore experiences of high school athletes in order to understand their occupational engagement after sustaining a sports-related concussion. The study explored the role occupational therapists (OTs) can play in post-concussion care while supporting adolescents in returning to meaningful occupations. METHODS: The study utilized a qualitative, phenomenological approach by conducting interviews with high school athletes to understand their participation in occupations during recovery. Six student-athletes from 14-18 years of age were interviewed. RESULTS: The five identified themes from the study included impacts on ADL performance, school performance, sleep, mental health, and driver safety. Student-athletes reported feelings of loneliness and loss of identity. Dressing, showering, grooming, and driving were disturbed due to balance deficits, headaches, and nausea. Participants reported decreased participation in social, sports, and leisure occupations due to heightened symptoms. CONCLUSIONS: Due to the considerable variability of disturbance in occupational participation post-concussion, occupational therapists can assist in creating and implementing individualized treatment plans to support high school athletes while recovering from a sports-related concussion.

Background: Mild Traumatic Brain Injury (mTBI) has been increasingly recognized as a public health concern due to its prevalence and potential to induce long-term cognitive impairment. We aimed to consolidate this observation by focusing on findings of neuropsychological assessments, neuroimaging, risk factors, and potential strategies for intervention to prevent and treat mTBI-associated cognitive impairments. Methods: A thorough search of PubMed, PsycINFO, and Embase databases was performed for studies published until 2024. Studies focusing on cognitive impairment after mTBI, with neurocognitive assessment as a primary outcome, were included. Results: We found consistent evidence of cognitive deficits, such as memory and attention impairments, and affected executive functions following mTBI. Neuroimaging studies corroborate these findings, highlighting structural and functional changes in the brain. Several risk factors for developing cognitive impairment post-mTBI were identified, including age, gender, genetics, and pre-existing mental health conditions. The efficacy of interventions, including cognitive rehabilitation and pharmaceutical treatment, varied across studies. Conclusions: Mild TBI can lead to significant long-term cognitive impairments, impacting an individual's quality of life. Further research is necessary to validate and standardize cognitive assessment tools post-mTBI, to elucidate the underlying neural mechanisms, and to optimize therapeutic interventions.
