A Pilot Randomized Controlled Trial of Cognitive-Behavioral Therapy for Insomnia in Adolescents With Persistent Postconcussion Symptoms

Interventions to Improve the Occupational Performance of Youth With Persistent Postconcussion Symptoms: A Systematic Review

IMPORTANCE

Persistent postconcussion symptoms (PPCS) may negatively affect youth's occupational performance in activities of daily living, education, play and leisure, social participation, and rest and sleep.

OBJECTIVE

This review provides occupational therapists with evidence related to interventions for youth with PPCS.

DATA SOURCES

Searches were performed in Embase, PubMed, SportDiscus, CINAHL, and Web of Science.

STUDY SELECTION AND DATA COLLECTION

Inclusion criteria were as follows: studies published in English from January 1, 2013, to February 7, 2023; youth ages 3 to 18 yr old; PPCS for at least 2 wk after injury; interventions within the scope of occupational therapy; and outcomes related to areas of occupation. All levels of evidence (1-5) were included and graded for quality using the Oxford Centre for Evidence-Based Medicine (2009) levels of evidence. This review followed Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines.

FINDINGS

Twenty articles met inclusion criteria (7 randomized controlled trials, 1 nonrandomized controlled group design, 3 single-group designs, 5 case series, and 4 single-subject designs). Interventions reviewed were active rehabilitation, vision-related interventions, psychoeducation, cognitive-behavioral therapy (CBT) techniques, the Cognitive Orientation to daily Occupational Performance (CO-OP), and music therapy. Strong evidence supports CBT, with significant clinical outcomes in sleep and education. Moderate strength of evidence supports psychoeducation and active rehabilitation for improving functional outcomes. More evidence is needed to make clinical recommendations regarding vision-related interventions, the CO-OP, and music therapy.

CONCLUSIONS AND RELEVANCE

Occupational therapists should consider CBT, psychoeducation, and active rehabilitation to improve occupational performance among youth with PPCS. Plain-Language Summary: Some youth will have persistent symptoms that do not resolve within 2 weeks after a concussion. Because of these persistent symptoms, they may have difficulty completing everyday activities. This review evaluated evidence addressing the ability of youth with persistent postconcussion symptoms (PPCS) to complete everyday activities. The authors found that cognitive-behavioral therapy, psychoeducation (aimed at helping youth understand and cope with their concussion symptoms), and active rehabilitation (aerobic and coordination exercises, such as jumping jacks and ball skills) should be considered when working with youth (ages 3-18 years) with PPCS. Using these interventions in occupational therapy sessions may improve the ability of youth to complete their everyday activities after a concussion.

Sport-Specific Recovery Trajectories for NCAA Collegiate Athletes Following Concussion

The recovery trajectories of collegiate athletes with sport-related concussion (SRC) are well characterized in contact/collision sports but are less well understood in limited contact sports with lower risk, reducing the ability of clinicians to effectively manage the return-to-play (RTP) process. The current study investigated the time to asymptomatic and RTP across a broad range of male and female collegiate sports and sought to group sports by recovery intervals. Data from the Concussion Assessment, Research and Education (CARE) Consortium included 1049 collegiate athletes who sustained a SRC while participating in game or practice/training of their primary sport. Injury setting and subsequent clinical presentation data were obtained. Survival analysis using the Cox Proportional Hazard model estimated the median recovery times for each sport. Optimal univariate K-means clustering grouped sports into recovery categories. Across all sports, median time to asymptomatic following SRC ranged from 5.9 (female basketball) to 8.6 days (male wrestling). Median RTP protocol duration ranged from 4.9 days (female volleyball) to 6.3 days (male wrestling). Median total RTP days ranged from 11.2 days (female lacrosse) to 16.9 days (male wrestling). Sport clusters based on recovery differences in time to asymptomatic (3) and RTP protocol duration (2) were identified. The findings from this study of a large sample of more than 1000 NCAA collegiate athletes with SRC show there exists ranges in recovery trajectories. Clinicians can thus manage athletes with similar guidelines, with individualized treatment and recovery plans.

How completely are randomized controlled trials of non-pharmacological interventions following concussion reported? A systematic review

PURPOSE

The study aimed to examine the reporting completeness of randomized controlled trials (RCTs) of non-pharmacological interventions following concussion.

METHODS

We searched MEDLINE, Embase, PsycInfo, CINAHL, and Web of Science up to May 2022. Two reviewers independently screened studies and assessed reporting completeness using the Template for Intervention Description and Replication (TIDieR), Consensus on Exercise Reporting Template (CERT), and international Consensus on Therapeutic Exercise aNd Training (i-CONTENT) checklists. Additional information was sought my study authors where reporting was incomplete. Risk of bias (ROB) was assessed with the Cochrane ROB-2 Tool. RCTs examining non-pharmacological interventions following concussion.

RESULTS

We included 89 RCTs (n = 53 high ROB) examining 11 different interventions for concussion: sub-symptom threshold aerobic exercise, cervicovestibular therapy, physical/cognitive rest, vision therapy, education, psychotherapy, hyperbaric oxygen therapy, transcranial magnetic stimulation, blue light therapy, osteopathic manipulation, and head/neck cooling. Median scores were: TIDieR 9/12 (75%; interquartile range (IQR) = 5; range: 5-12), CERT 17/19 (89%; IQR = 2; range: 10-19), and i-CONTENT 6/7 (86%; IQR = 1; range: 5-7). Percentage of studies completely reporting all items was TIDieR 35% (31/89), CERT 24% (5/21), and i-CONTENT 10% (2/21). Studies were more completely reported after publication of TIDieR (t87 = 2.08; p = 0.04) and CERT (t19 = 2.72; p = 0.01). Reporting completeness was not strongly associated with journal impact factor (TIDieR: rs = 0.27; p = 0.01; CERT: rs = -0.44; p = 0.06; i-CONTENT: rs = -0.17; p = 0.48) or ROB (TIDieR: rs = 0.11; p = 0.31; CERT: rs = 0.04; p = 0.86; i-CONTENT: rs = 0.12; p = 0.60).

CONCLUSION

RCTs of non-pharmacological interventions following concussion demonstrate moderate to good reporting completeness, but are often missing key components, particularly modifications, motivational strategies, and qualified supervisor. Reporting completeness improved after TIDieR and CERT publication, but publication in highly cited journals and low ROB do not guarantee reporting completeness.

Cognitive Behavioral Therapy for Insomnia Improves Sleep Outcomes in Individuals With Concussion: A Preliminary Randomized Wait-List Control Study

OBJECTIVE

Cognitive behavioral therapy for insomnia (CBT-I) is the gold standard treatment for insomnia, but there is limited evidence on the treatment effect of CBT-I in individuals after a concussion. Therefore, the main purpose of this study was to evaluate the treatment effect of CBT-I on sleep outcomes and postconcussion symptoms.

SETTING

This study was conducted at an academic institution. The CBT-I sessions were conducted using a teleconferencing system (Zoom).

PARTICIPANTS

Participants were eligible to participate if they were at least 4 weeks post- concussion, aged 18 to 64 years, and scored 10 or more on the Insomnia Severity Index. A total of 40 people were enrolled; 32 participants were included in analyses.

DESIGN

This was a randomized controlled wait-list study. Participants were randomized into starting the CBT-I intervention immediately after the baseline assessment or into the wait-list group for 6 weeks before starting CBT-I. Assessments were performed at baseline, 6, 12, and 18 weeks.

MAIN MEASURES

The primary outcome was the Insomnia Severity Index. Secondary measures included the Pittsburg Sleep Quality Index, Post-Concussion Symptom Scale, and Beck Depression and Anxiety Inventories. Statistical analyses included a repeated-measures analysis of variance, t tests, and mixed linear regression modeling.

RESULTS

There was a group-by-time interaction for the sleep outcomes but not for the concussion or mood outcomes. Differences were seen between groups on sleep outcomes, symptom severity, and depression. The treatment effect was maintained following CBT-I for all outcomes. Improvement in sleep outcomes was predictive of improvement in postconcussion symptom severity and number of symptoms.

CONCLUSIONS

CBT-I reduces insomnia in individuals with concussions, and improved sleep was associated with lower postconcussion and mood symptoms. These effects were maintained 6 to 12 weeks following the intervention.

Shorter Telomere Length Is Associated With Older Age, Poor Sleep Hygiene, and Orthopedic Injury, but Not Mild Traumatic Brain Injury, in a Cohort of Canadian Children

BACKGROUND

Predicting recovery following pediatric mild traumatic brain injury (mTBI) remains challenging. The identification of objective biomarkers for prognostic purposes could improve clinical outcomes. Telomere length (TL) has previously been used as a prognostic marker of cellular health in the context of mTBI and other neurobiological conditions. While psychosocial and environmental factors are associated with recovery outcomes following pediatric mTBI, the relationship between these factors and TL has not been investigated. This study sought to examine the relationships between TL and psychosocial and environmental factors, in a cohort of Canadian children with mTBI or orthopedic injury (OI).

METHODS

Saliva was collected at a postacute (median 7 days) timepoint following injury to assess TL from a prospective longitudinal cohort of children aged 8 to 17 years with either mTBI (n = 202) or OI (n = 90), recruited from 3 Canadian sites. Questionnaires regarding psychosocial and environmental factors were obtained at a postacute follow-up visit and injury outcomes were assessed at a 3-month visit. Univariable associations between TL and psychosocial, environmental, and outcome variables were assessed using Spearman's correlation. Further adjusted analyses of these associations were performed by including injury group, age, sex, and site as covariates in multivariable generalized linear models with a Poisson family, log link function, and robust variance estimates.

RESULTS

After adjusting for age, sex, and site, TL in participants with OI was 7% shorter than those with mTBI (adjusted mean ratio = 0.93; 95% confidence interval, 0.89-0.98; P = .003). As expected, increasing age was negatively associated with TL (Spearman's r = -0.14, P = .016). Sleep hygiene at 3 months was positively associated with TL (adjusted mean ratio = 1.010; 95% confidence interval, 1.001-1.020; P = .039).

CONCLUSION

The relationships between TL and psychosocial and environmental factors in pediatric mTBI and OI are complex. TL may provide information regarding sleep quality in children recovering from mTBI or OI; however, further investigation into TL biomarker validity should employ a noninjured comparison group.

Does Sleep Quality Influence Recovery Outcomes After Postconcussive Injury in Children and Adolescents?

OBJECTIVE

To determine whether objective parameters of sleep quality differ throughout recovery between children and adolescents who experienced an early return to school (RTS) and those who had a delayed RTS or did not return at all during the study period.

SETTING

Sleep parameters reflective of sleep quality were evaluated in participants' natural sleeping habitat throughout 9 weeks postinjury.

PARTICIPANTS

Ninety-four children and adolescents (aged 5-18 years) with diagnosed concussion.

DESIGN

Prospective cohort. Participants followed RTS protocols.

MAIN MEASURES

Actigraphy-derived estimates of total sleep time (TST), sleep efficiency (SE), wake after sleep onset (WASO), average arousal length (AAL), and number of arousals (NOAs) per hour were assessed. The length of time from injury until RTS was determined for each participant. Participants were categorized into an early RTS or delayed RTS group based on their time to RTS.

RESULTS

Both TST and SE were significantly greater in the early RTS group. WASO duration, AAL, and NOAs were significantly greater in the delayed RTS group. Differences between RTS groups were most apparent during weeks 1 to 5 postinjury.

CONCLUSIONS AND CLINICAL IMPLICATIONS

Participants who returned to school earlier had significantly better objective sleep quality than participants who experienced a delayed RTS. This study provides evidence in support of a relationship between sleep quality and time to RTS in children and adolescents with concussion. Considering early monitoring of sleep, education regarding sleep hygiene, and access to age-appropriate sleep interventions may be helpful in pediatric concussion recovery.

Management of Psychological Complications Following Mild Traumatic Brain Injury

PURPOSE OF REVIEW

It has been clear for decades that psychological factors often contribute to mild traumatic brain injury (mTBI) outcome, but an emerging literature has begun to clarify which specific factors are important, when, for whom, and how they impact recovery. This review aims to summarize the contemporary evidence on psychological determinants of recovery from mTBI and its implications for clinical management.

RECENT FINDINGS

Comorbid mental health disorders and specific illness beliefs and coping behaviors (e.g., fear avoidance) are associated with worse recovery from mTBI. Proactive assessment and intervention for psychological complications can improve clinical outcomes. Evidence-based treatments for primary mental health disorders are likely also effective for treating mental health disorders after mTBI, and can reduce overall post-concussion symptoms. Broad-spectrum cognitive-behavioral therapy may modestly improve post-concussion symptoms, but tailoring delivery to individual psychological risk factors and/or symptoms may improve its efficacy. Addressing psychological factors in treatments delivered primarily by non-psychologists is a promising and cost-effective approach for enhancing clinical management of mTBI. Recent literature emphasizes a bio-psycho-socio-ecological framework for understanding mTBI recovery and a precision rehabilitation approach to maximize recovery. Integrating psychological principles into rehabilitation and tailoring interventions to specific risk factors may improve clinical management of mTBI.

Efficacy of Cognitive Behavioral Therapy for Insomnia for the Treatment of Child and Adolescent Anxiety and Depression: A Systematic Review From Randomized Controlled Trials

ABSTRACT

Cognitive behavioral therapy for insomnia (CBT-I) has shown promising results in the adult population. However, there is not enough evidence for children and adolescents. Hence, we evaluated the current evidence of CBT-I in the treatment of anxiety and depression in children and adolescents. Published randomized clinical trials published before June 2020 were searched from PubMed, Cochrane Library of database, clinicaltrials.gov, and Google Scholar. Out of seven included studies, six studies assessed the effect of CBT-I on depression, and five assessed the effect on anxiety. In this review, most studies in this review showed a strong effect of CBT-I on symptoms of depression. Although a positive effect of CBT-I on anxiety was noted, only a small number of studies have considered this management. These findings should be considered preliminary, and further large-scale studies are warranted to further explore this finding further.

Functional Outcomes, Injury Variables, and Athlete Characteristics Associated with Post-Concussion Sleep Disturbance

OBJECTIVE

To examine the relationship between sleep disturbance and functional outcomes following a concussion. Also, to explore athlete and injury-related variables that may be related to risk factors for poor sleep following concussion.

METHOD

124 collegiate athletes completed a neuropsychological evaluation within 14 days of sustaining a sport-related concussion (SRC). Athletes were categorized as sleep disturbed (n = 52) or not sleep disturbed (n = 72). Outcome variables included symptom reports, cognitive performance (mean performance and variability), and mood (depression). Injury characteristics and athlete characteristics explored were loss of consciousness (LOC) associated with the injury, whether the athlete was immediately removed from play, and history of prior concussions.

RESULTS

Sleep disturbed athletes reported more symptoms, F(4, 119) = 7.82, p < 0.001, ƞ2 = 0.21, were more likely to be symptomatic at the time of testing, χ2(1, N = 124) = 19.79, p < 0.001, φ = 0.40, and were marginally more likely to experience clinically significant depression, χ2(1, N = 120) = 3.03, p = 0.08, φ = 0.16, than not sleep disturbed athletes. There were no cognitive differences between the groups, p > 0.05. A greater proportion of sleep disturbed athletes experienced LOC (30%) compared to not sleep disturbed athletes (13%), χ2(1, N = 118) = 4.99, p = 0.03, φ = -0.21.

CONCLUSION

Sleep disturbances following SRC are associated with a broad range of self-reported symptoms. LOC may be associated with an increased risk of developing sleep disturbances; alternatively, sleep disturbances may increase the risk of LOC following concussion.

Assessing Cognitive Behavioral Therapy for Insomnia to Improve Sleep Outcomes in Individuals With a Concussion: Protocol for a Delayed Randomized Controlled Trial

BACKGROUND

Sleep disturbances post concussion have been associated with more frequent and severe concussion symptoms and may contribute to poorer recovery. Cognitive behavioral therapy for insomnia (CBT-I) is an effective treatment for insomnia; however, it remains unclear if this treatment method is effective in improving sleep outcomes and reducing concomitant postconcussion symptoms.

OBJECTIVE

The hypotheses for this study are that (1) CBT-I will improve sleep outcomes and (2) CBT-I will improve concomitant postconcussion symptoms.

METHODS

In total, 40 individuals who are within ≥4 weeks of postconcussion injury and have insomnia symptoms will be enrolled in this randomized controlled trial. Participants will be randomized into either a group that starts a 6-week CBT-I program immediately after baseline or a waitlist control group that starts CBT-I following a 6-week waiting period. All participants will be reassessed 6, 12, and 18 weeks after baseline. Standardized assessments measuring sleep outcomes, postconcussion symptoms, and mood will be used. Linear regression and t tests will be used for statistical analyses.

RESULTS

Enrollment of 40 participants was completed July 2022, data collection will be completed in November 2022, and publication of main findings is anticipated in May 2023. It is anticipated that participants experience reduced insomnia symptoms and postconcussion symptoms following CBT-I and these improvements will be retained for at least 12 weeks. Additionally, we expect to observe a positive correlation between sleep and postconcussion symptom improvement.

CONCLUSIONS

Successful completion of this pilot study will allow for a better understanding of the treatment of insomnia and postconcussion symptoms in individuals following a concussion.

Hyperbaric oxygen therapy in children with post-concussion syndrome improves cognitive and behavioral function: a randomized controlled trial

Persistent post-concussion syndrome (PPCS) is a common and significant morbidity among children following traumatic brain injury (TBI) and the evidence for effective PPCS treatments remains limited. Recent studies have shown the beneficial effects of hyperbaric oxygen therapy (HBOT) in PPCS adult patients. This randomized, sham-control, double blind trial evaluated the effect of hyperbaric oxygen therapy (HBOT) on children (age 8–15) suffering from PPCS from mild-moderate TBI events six months to 10 years prior. Twenty-five children were randomized to receive 60 daily sessions of HBOT (n = 15) or sham (n = 10) treatments. Following HBOT, there was a significant increase in cognitive function including the general cognitive score (d = 0.598, p = 0.01), memory (d = 0.480, p = 0.02), executive function (d = 0.739, p = 0.003), PPCS symptoms including emotional score (p = 0.04, d = – 0.676), behavioral symptoms including hyperactivity (d = 0.244, p = 0.03), global executive composite score (d = 0.528, p = 0.001), planning/organizing score (d = 1.09, p = 0.007). Clinical outcomes correlated with significant improvements in brain MRI microstructural changes in the insula, supramarginal, lingual, inferior frontal and fusiform gyri. The study suggests that HBOT improves both cognitive and behavioral function, PPCS symptoms, and quality of life in pediatric PPCS patients at the chronic stage, even years after injury. Additional data is needed to optimize the protocol and to characterize the children who can benefit the most.

Interdisciplinary Rehabilitation for Concussion Recovery (i-RECOveR): protocol of an investigator-blinded, randomised, case series with multiple baseline design to evaluate the feasibility and preliminary efficacy of a 12-week treatment for persistent post-concussion symptoms

BACKGROUND

Up to 25% of concussed individuals experience persistent post-concussion symptoms (PPCSs) which may interfere with the return to pre-injury activities and cause significant stress. Given that multiple etiological factors are thought to contribute to PPCSs, an interdisciplinary approach is recommended. This pilot study aims to primarily investigate the feasibility of a novel interdisciplinary treatment for PPCSs. Given this intervention is novel, uncertainty exists in terms of potential recruitment and retention rates, adverse events, and treatment adherence and fidelity. These factors will be explored to inform the feasibility of a phase-2 randomised controlled trial. Preliminary efficacy of this intervention will also be explored.

METHODS

Fifteen individuals with mild traumatic brain injury and PPCSs will receive up to 12 weeks of interdisciplinary treatments including psychology, physiotherapy, and medical interventions. Primary feasibility outcomes including data on recruitment and retention rates and treatment adherence will be explored descriptively. The cognitive therapy rating scale will be used to assess treatment fidelity. A single-case series with multiple baseline design will be used to explore preliminary efficacy. Participants will be randomly assigned to baseline phases of 2, 4, or 6 weeks. Regarding patient-centred secondary outcomes, the Rivermead Post-Concussion Symptoms Questionnaire will be assessed three times a week during baseline and treatment phases. Secondary outcomes also include measures of mood, sleep and fatigue, physical functioning, return to activity, and health-related quality of life. Patient-centred outcomes will be assessed at baseline, pretreatment, post-treatment, and one- and three-month follow-up. Thematic analysis of participant experiences will be explored through qualitative interviews.

DISCUSSION

Results from this trial will inform the feasibility and preliminary efficacy of this interdisciplinary concussion intervention and whether proceeding to a future definitive phase-2 randomised controlled trial is worthwhile. Understanding the end-user perspective of the treatment will also enable modifications to the treatment protocol for future trials to best suit the needs of individuals with PPCSs after mTBI. Outcomes from this trial can be directly translated into community rehabilitation programmes.

Mental Health Outcomes Across the Lifespan in Individuals With Persistent Post-Concussion Symptoms: A Scoping Review

Objective:

Concussion is a common yet heterogenous injury. Approximately 15–30% of cases present with persistent post-concussion symptoms (PPCS), continuing 4 weeks or more post-injury in children, youth, and adolescents, and 3 months or more in adults. There are known bidirectional links between PPCS and mental health outcomes. The focus of this scoping review is to explore the literature on mental health outcomes in individuals experiencing PPCS. Research objectives were to explore: (1) the mental health outcomes of individuals with PPCS and types of assessments used to identify mental health outcomes this group, and (2) how mental health outcomes compare in terms of similarities and differences among pediatric and adult populations with PPCS.

Method

Ovid MEDLINE; EMBASE; CINAHL, and PsycInfo databases were searched. After title and abstract screening of 11,920 studies, 481 articles were reviewed. Twenty-five papers met inclusion criteria. Results were organized by mental health outcomes of pediatric and adult populations, separately.

Results

There was a significantly higher number of studies devoted to adult populations. Of the 25 studies, 19 (76%) focused on adults, while six (24%) focused on adolescents. In adult populations, studies focused on symptoms of: anxiety (n = 2), depression (n = 8), and anxiety and depression (n = 9). Two studies assessed other emotional outcomes (10.5%). Within pediatric populations, an equal number of studies explored symptoms of: anxiety (n = 2), depression (n = 2), and anxiety and depression (n = 2). No studies focused on other emotional outcomes. Studies ranged greatly in methods, design, and control group. Most studies reported higher psychiatric symptoms of anxiety and/or depression in those with PPCS compared to individuals with recovered concussion or healthy controls.

Discussion

This review contributes to the understanding of mental health outcomes in those experiencing PPCS. Mental health and PPCS requires greater attention in pediatric populations, and consider strategies for those experiencing PPCS and mental health impacts. Future studies should consider including a wider range of emotional outcomes in their design, not limited to anxiety and depression. Study results may lead to improvements and research in the identification, assessment, and management of PPCS and mental health.

Neuropsychiatric Treatment for Mild Traumatic Brain Injury: Nonpharmacological Approaches

Postconcussive symptoms following mild traumatic brain injury (mTBI)/concussion are common, disabling, and challenging to manage. Patients can experience a range of symptoms (e.g., mood disturbance, headaches, insomnia, vestibular symptoms, and cognitive dysfunction), and neuropsychiatric management relies heavily on nonpharmacological and multidisciplinary approaches. This article presents an overview of current nonpharmacological strategies for postconcussive symptoms including psychoeducation; psychotherapy; vestibular, visual, and physical therapies; cognitive rehabilitation; as well as more novel approaches, such as neuromodulation. Ultimately, treatment and management of mTBI should begin early with appropriate psychoeducation/counseling, and be tailored based on core symptoms and individual goals.

Effects of COVID-19-Related Anxiety and Sleep Problems on Loneliness and Feelings of School Refusal in Adolescents

BACKGROUND

COVID-19-related anxiety, sleep problems, and loneliness may be risk factors for school refusal in children and adolescents. However, few studies have examined the mechanisms by which these risk factors cause school refusal. This study examined the process by which COVID-19-related anxiety, sleep problems, and loneliness cause school refusal, using structural equation modeling.

METHODS

In this cross-sectional questionnaire-based study, 256 (109 male, 147 female, mean age: 15.37 ± 0.48 years) senior high school students were asked to complete the Stress and Anxiety associated with Viral Epidemics-6 questionnaire to assess COVID-19-related anxiety, the Athens Insomnia Scale (AIS), Sleep Debt Index (SDI), and chronotype (MSFsc) to assess sleep problems, the Three-Item Loneliness Scale (TILS) to assess loneliness, and Feelings of School-Avoidance Scale (FSAS) to assess school refusal.

RESULTS

Structural equation modeling showed that sleep problems affected loneliness (β = 0.52) and feelings of school refusal (β = 0.37), and that loneliness affected feelings of school refusal (β = 0.47). There was no significant pathway of COVID-19-related anxiety on sleep problems, loneliness, or feelings of school refusal. The indirect effect of sleep problems on feelings of school refusal through loneliness was significant. The results of hierarchical multiple regression analysis showed that AIS (β = 0.30) and SDI (β = 0.13) scores were associated with TILS, and AIS (β = 0.26) and MSFsc (β = -0.14) scores were associated with FSAS scores.

CONCLUSION

The findings of this study showed that sleep problems affected feelings of school refusal via both direct and indirect pathways through the exacerbation of loneliness. To prevent school refusal in adolescents, addressing the indirect pathway via loneliness could be effective in improving insomnia and sleep debt, while addressing the direct pathway could be effective in improving insomnia and chronotype.

Effects of Cognitive Behavioral Therapy on Pain and Sleep in Adults with Traumatic Brain Injury: A Systematic Review and Meta-Analysis

The objective of this study was to systematically review the literature on the effects of cognitive behavioral therapy (CBT) on insomnia and pain in patients with traumatic brain injury (TBI). PubMed, Embase, the Cochrane Library, Cumulative Index to Nursing and Allied Health, and Web of Science databases were searched. Outcomes, including pain, sleep quality, and adverse events, were investigated. Differences were expressed using mean differences (MDs) with 95% confidence intervals (CIs). The statistical analysis was performed using STATA 16.0. Twelve trials with 476 TBI patients were included. The included studies did not indicate a positive effect of CBT on pain. Significant improvements were shown for self-reported sleep quality, reported with the Pittsburgh Self-Reported Sleep Quality Index (MD, -2.30; 95% CI, -3.45 to -1.15; P < 0.001) and Insomnia Severity Index (MD, -5.12; 95% CI, -9.69 to -0.55; P = 0.028). No major adverse events related to CBT were reported. The underpowered evidence suggested that CBT is effective in the management of sleep quality and pain in TBI adults. Future studies with larger samples are recommended to determine significance. This trial is registered with PROSPERO registration number CRD42019147266.

Prevalence and risk factors for depression, anxiety and suicidal ideation in youth with persistent post-concussive symptoms (PPCS)

Objectives: To assess the prevalence and risk factors for emotional distress in youth with persistent post-concussive symptoms (PPCS) greater than one month.Methods: We used baseline data from an intervention study for youth with PPCS, utilizing Poisson regression to examine factors associated with exceeding clinical cut-points on measures of depression, anxiety, self-harm and suicidal ideation. Predictors included: age, sex, socioeconomic status, mental health history, duration of concussion symptoms, history of prior concussion, trauma history and sleep quality.Results: The sample included 200 youth with PPCS, (mean 14.7 SD 1.7 years, 82% white, 62% female). Forty percent reported clinically significant depressive symptoms, 25% anxiety, 14% thoughts of self-harm and 8% thoughts of suicide. History of depression was associated with 3-fold higher risk for thoughts of self-harm (95% CI:1.82-6.99) and 6-fold higher risk for suicidal ideation (95% CI:1.74-24.46). Better sleep quality was associated with lower risk for all outcomes. History of prior concussion and duration of PPCS were not significantly associated with any outcomes.Conclusions: Suicidal thoughts are common post-concussion, and history of depression is a strong risk factor. Tailored interventions may be needed to address mental health in this population.

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.

The Nocebo Effect and Pediatric Concussion

While placebo effects are well recognized within clinical medicine, "nocebo effects" have received much less attention. Nocebo effects are problems caused by negative expectations derived from information or treatment provided during a clinical interaction. In this review, we examine how nocebo effects may arise following pediatric concussion and how they may worsen symptoms or prolong recovery. We offer several suggestions to prevent, lessen, or eliminate such effects. We provide recommendations for clinicians in the following areas: terminology selection, explicit and implicit messaging to patients, evidence-based recommendations, and awareness of potential biases during clinical interactions. Clinicians should consider the empirically grounded suggestions when approaching the care of pediatric patients with concussion.

The persistence of sleep disturbance and its correlates in children with moderate to severe traumatic brain injury: A longitudinal study

OBJECTIVES

The primary aim was to examine whether sleep disturbances persist in children in the chronic stage of recovery from moderate or severe traumatic brain injury (TBI). The secondary aim was to examine whether memory difficulties and/or other previously identified factors relate to sleep disturbances in children with moderate to severe TBI.

METHODS

This longitudinal study included 21 children with moderate to severe TBI, 8-18 years old, recruited from an urban tertiary paediatric specialised brain injury rehabilitation unit. Participants were seen 5 years and again 7 years post-injury, on average. Sleep disturbances were assessed with Sleep Disturbance Scale for Children (SDSC). Correlates that were considered included indicators of TBI severity, and questionnaires assessing everyday memory, fatigue, internalizing and externalizing behaviors and pain intensity.

RESULTS

The SDSC scores of children with moderate to severe TBI indicated greater disturbances in initiating and maintaining sleep, arousal, sleep-wake transition, and excessive somnolence relative to the norms, at follow-up. The mean SDSC scores and the number of participants with subclinical to clinical sleep disturbances on the SDSC remained unchanged from baseline to follow-up. At follow-up, the SDSC initiating and maintaining sleep, and excessive somnolence scales were associated with poorer everyday memory and greater fatigue.

CONCLUSIONS

Children with moderate to severe TBI experience ongoing sleep disturbances for years post-injury. Greater sleep disturbances are associated with worse functional outcomes. Further research into sleep disturbances and development of treatments is important, as it could improve the outcomes of children with TBI.

Seeing the Whole Elephant: a scoping review of behavioral treatments for pediatric insomnia

Pediatric insomnia is common, impacting up to a third of typically-developing, healthy children, and over 80% of children with neurodevelopmental disorders or chronic medical conditions. Previous reviews of behavioral interventions for pediatric insomnia have had a limited focus on a single age group, a specific population, and/or only randomized controlled trials. Furthermore, few reviews have considered non-sleep outcomes of both children and their parents. This scoping review provides a broader context, including studies regardless of research design or population, along with sleep and non-sleep study outcomes. Clear gaps in the literature were identified, highlighting the need for additional research in different populations, including school-age children and adolescents, racial/ethnic groups around the world, as well as youth with medical or psychiatric disorders. In addition, more research is needed on different features of treatment, including the delivery mode, involvement of all family members, non-sleep outcomes, and long-term follow-up.

Determining the Effectiveness of Using Patient-Reported Outcomes in Pediatric Clinical Practices

PROBLEM

Patient-reported outcomes (PROs) are increasingly recognized in pediatric clinical care as adding essential information relevant to actual care. However, the effectiveness of using PROs in pediatric clinical settings has not been fully explored with synthesized evidence. The aim of this study was to evaluate the effectiveness of using patient-reported outcomes in pediatric clinical practices.

ELIGIBILITY CRITERIA

We searched four English and three Chinese databases to identify studies that examine the effectiveness of using PROs in pediatric clinical practices published from the inception date of each database to January 2020.

SAMPLE

Ten articles met the inclusion criteria.

RESULTS

There was wide a variation in the ten studies' designs, samples, PROs administered (type, length, timing, mode), and type of outcomes evaluated. The effect sizes of using PROs on three categories of outcomes (patient, process of care and health service) were assessed. Of 70 measured outcomes, 32 were positive, 5 were negative, and 33 were mixed.

CONCLUSIONS

Overall, there is a weak but trending positive impact of using PROs in pediatric clinical practice.

IMPLICATIONS

More rigorous study designs with sources of bias controlled are needed to more directly assess the impact of using PROs in pediatric care. If findings continue to be positive, then an implementation model addressing the numerous influencing factors is recommended to integrate PROs into pediatric care.

Efficacy of Melatonin for Sleep Disturbance in Children with Persistent Post-Concussion Symptoms: Secondary Analysis of a Randomized Controlled Trial

Sleep disturbances are commonly reported in children with persistent post-concussion symptoms (PPCS). Melatonin treatment is often recommended, yet supporting evidence is scarce. We aimed to evaluate the efficacy of treatment with melatonin for sleep disturbance in youth with PPCS following mild traumatic brain injury (mTBI). This article is a secondary analysis of a clinical trial of melatonin compared with placebo to treat PPCS. Youth (8-18 years of age) with PPCS and significant sleep-related problems (SRPs) at 4-6 weeks post-injury were eligible. Exclusion criteria: significant medical/psychiatric history; previous concussion/mTBI within 3 months. Treatment groups were: placebo, melatonin 3 mg, or melatonin 10 mg. Primary outcome was change in SRPs measured using the Post-Concussion Symptom Inventory (PCSI) after 2 weeks of treatment. Secondary outcomes included change in actigraphy sleep efficiency, duration, onset latency, and wake-after-sleep-onset. Behavior was measured using Behaviour Assessment for Children (2nd edition). Seventy-two participants (mean age 14.0, standard deviation [SD] = 2.6) years; 60% female) with PPCS and significant sleep disturbance were included in the secondary analysis: placebo (n = 22); melatonin 3 mg (n = 25); melatonin 10 mg (n = 25). Sixty-four participants had actigraphy data. SRPs decreased across all groups over time with a significant effect of melatonin 3 mg (3.7; 95% confidence interval [CI]: 2.1, 5.4) compared with placebo (7.4; 95% CI: 4.2, 10.6) and melatonin 10 mg (6.4; 95% CI: 3.6, 9.2). Sleep duration increased in the melatonin 3 mg (43 min; 95% CI: 6, 93) and melatonin 10 mg groups (55 min; 95% CI: 5, 104) compared with placebo. A per protocol analysis demonstrated improved sleep efficiency in the melatonin 10 mg group (p = 0.029). No serious adverse events were reported. Depressive symptoms significantly decreased with melatonin 3 mg (-4.7; 95% CI: -9.2, -.2) but not with melatonin 10 mg (-1.4, 95% CI: -5.9, 3.2) treatment compared with placebo. Changes in cognition or behavior were otherwise not significantly different between treatment groups. Short-term melatonin is a well-tolerated treatment for sleep disturbance in youth with PPCS following mTBI. In this context, it may also be associated with a reduction in depressive symptoms.

Concussion Symptom Treatment and Education Program: A Feasibility Study

OBJECTIVE

To evaluate the feasibility and potential benefits of a manualized, brief cognitive-behavioral therapy-based intervention program for children and adolescents with persistent postconcussive symptoms.

SETTING

Two outpatient pediatric concussion programs in the United States.

PARTICIPANTS

Patients aged 8 to 17 years who sustained concussions between 2 and 12 months prior to enrollment.

DESIGN

Pre-/postretrospective study.

MAIN MEASURES

SCAT-3; HBI; PedsQL 4.0 Generic Core Scales; and RCADS.

RESULTS

Thirty children and adolescents completed the treatment program. Self- and parent-reported postconcussive symptoms, quality of life, and internalizing symptoms significantly improved with treatment. Mixed-effects models revealed a significant decline in self-reported postconcussive symptoms across treatment sessions, a = -2.07, SE = 0.25, P < .001. The largest change occurred between sessions 2 and 3, following the session focusing on concussion psychoeducation and sleep hygiene (estimated mean change between sessions 2 and 3 = -4.72, P < .0001).

CONCLUSIONS

Our findings indicate that a 6-session manualized cognitive behavioral intervention is feasible to initiate in an outpatient clinic 1 to 12 months following a pediatric mild traumatic brain injury. With a manualized format, clinicians at most levels of training should be able to implement this treatment manual and flexibly adapt as needed when working with children and adolescents who are experiencing delayed symptom recovery following concussion.

Sleep Symptoms Predict School Attendance After Pediatric Concussion

This study examined the relationship between postconcussive symptom domain and school attendance. Retrospective chart review was completed for 88 children aged 6 to 18 years who were evaluated within 30 days postinjury. Hierarchical multiple regression was used to assess the association of physical, cognitive, emotional, and sleep symptoms with extent of school attendance. A subgroup multiple regression analysis was conducted to evaluate whether age affected the relationship of symptoms to school attendance. After controlling for demographic variables and total number of symptoms, a higher number of postconcussive sleep symptoms strongly predicted less school attendance. Specifically, older children (≥14 years old) with more sleep symptoms demonstrated less school attendance. For children presenting for specialty care after concussion, sleep symptoms are unfavorably associated with return to school. Future work aimed at optimizing sleep regulation following concussion may assist with early reengagement in school as recommended by current concussion management guidelines.

Sleep Parameters and Overnight Urinary Melatonin Production in Children With Persistent Post-concussion Symptoms

BACKGROUND

Sleep disturbance is common after a mild traumatic brain injury (mTBI) in children, yet its biology is poorly understood. We aimed to explore sleep-related problems (SRPs), sleep-activity patterns, and endogenous melatonin production in children with different recovery trajectories following mTBI. We hypothesized that children with delayed recovery would have more SRPs and abnormal sleep-activity patterns, which would correlate with lower overnight melatonin production.

METHODS

In this prospective controlled cohort study, we enrolled 83 children with persistent symptoms, 26 children who had clinically recovered following mTBI, and 25 healthy controls. SRPs were evaluated using the sleep subscale of the Post-Concussion Symptom Inventory. Sleep actigraphy was performed for five to seven days at 37 (S.D. 7) days post-injury. Health-related quality of life and mood disturbance was assessed using the Child Health Questionnaire and the Behavior Assessment System for Children, respectively. Endogenous melatonin production was assessed using overnight urine collection.

RESULTS

The groups were similar in age (13.9 [S.D. 2.6] years) and sex (52% female). Regression analysis demonstrated increased SRP in the symptomatic group (9.0; 95% confidence interval: 7.6, 11.1) compared with the recovered group (1.6; 95% confidence interval: 1.0, 2.4) and controls (2.0; 95% confidence intervals: 1.2, 3.2). Actigraphy parameters and urinary melatonin levels were not significantly different between groups. Neither SRPs nor actigraphy parameters correlated with anxiety and depression scores.

CONCLUSIONS

Although children with persistent post-concussion symptoms reported more SRPs, this was not related to actigraphy sleep parameters or melatonin production. Further research is warranted to understand the pathophysiology of post-traumatic sleep disturbance.

Acceptability, feasibility, and usability of a manualized cognitive behavioural programme for treatment of insomnia in children who sustained traumatic brain injury: A service providers' perspective

Sleep disturbances, especially insomnia, are common and associated with poor outcomes in children following traumatic brain injury (TBI). Yet, clinical treatment guidelines are lacking. Thus, we developed a manualized cognitive-behavioural programme for treatment of insomnia (CBT-I) in children who sustained TBI. The aim of this study was to determine acceptability, feasibility, and usability of the programme from the service providers' perspective. This observational study used an explanatory mixed-methods design. Fifteen clinicians experienced in working with children, patients with sleep disturbances or brain injuries participated. On review of the treatment programme, clinicians completed an online survey assessing (i) the overall format, aesthetics, and clarity of the programme, and (i) the overall quality of the intervention. Analyses involved descriptive statistics and a thematic analysis. Clinician's ratings indicated a high level of agreement in the acceptability, feasibility, and usability of the programme, ranging from 70.9% (the therapist manual) to 86.9% (the intervention approach). Thematic analysis revealed suggestions that related to the developmental appropriateness, feasibility, and usability of the programme. The findings of our study will be used to modify the CBT-I treatment programme that will be further validated in a feasibility clinical trial involving children aged 6-10 years who sustained TBI.

Outcomes of a brief coping skills group intervention for adults with severe postconcussion symptoms

Aim:

The aim of this study was to evaluate a brief psychologically informed coping skills group intervention for adults with severe prolonged symptoms following mild traumatic brain injury (mTBI).

Methodology & results:

Patients attended an education session about mTBI; 22 patients completed an additional coping skills group intervention, 16 declined/stopped the intervention early and 19 were not offered the intervention. At follow-up, patients who completed the intervention reported a similar degree of symptom improvement and disability as those who did not complete the intervention. The majority of patients who completed the intervention were satisfied with it and perceived it to be credible.

Conclusion:

The coping skills intervention was not associated with measurable clinical benefit. Recommendations for improving psychological interventions for mTBI are discussed.
