Depression and health related quality of life in adolescent survivors of a traumatic brain injury: a pilot study

Adverse childhood experiences and brain injury in younger children: Findings from the 2021-2022 National Survey of Children's Health

PURPOSE

The purpose of this study was to extend on previous research finding by investigating adverse childhood experiences (ACEs) and brain injury in children younger than 12 years old.

METHODS

A total of 58,601 US children under 12 years old were included in the 2020-2021 National Survey of Children's Health, a self-reported national survey administered to caregivers.

RESULTS

ACEs were significantly associated with increased risk for unconfirmed (χ2 (55891, 55904) = 141.84, p < 0.001, R2 = .03) and confirmed brain injury, χ2 (56481, 56494) = 508.28, p < 0.001, R2 = .05 when accounting for demographic characteristics. The association between ACEs and brain injury was not contingent on sports involvement; females not involved in sports had the strongest association between ACEs and brain injury (χ2 (10938, 10951) = 99.40, p < 0.001, R2 = .03) compared to sports-involved females and males. For children under 12 years old with brain injury, the relations between experiencing at least one ACE and health and educational outcomes were significant for all health and educational outcomes (p < 0.001).

CONCLUSIONS

Caregiver education on and screening for brain injury in families experiencing ACEs would likely support more timely identification and management of co-occurring brain injury in this population. Further research is needed to identify prevention, assessment, and management strategies that would be specifically beneficial to children at risk for co-occurring brain injury and ACEs to improve health and educational outcomes.

Traumatic brain injuries: a neuropsychological review

The best predictor of functional outcome in victims of traumatic brain injury (TBI) is a neuropsychological evaluation. An exponential growth of research into TBI has focused on diagnosis and treatment. Extant literature lacks a comprehensive neuropsychological review that is simultaneously scholarly and practical. In response, our group included, and went beyond a general overview of TBI's, which commonly include definition, types, severity, and pathophysiology. We incorporate reasons behind the use of particular neuroimaging techniques, as well as the most recent findings on common neuropsychological assessments conducted in TBI cases, and their relationship to outcome. In addition, we include tables outlining estimated recovery trajectories of different age groups, their risk factors and we encompass phenomenological studies, further covering the range of existing-promising tools for cognitive rehabilitation/remediation purposes. Finally, we highlight gaps in current research and directions that would be beneficial to pursue.

Final Validation of the Quality of Life after Brain Injury for Children and Adolescents (QOLIBRI-KID/ADO) Questionnaire

Until recently, no disease-specific health-related quality of life (HRQoL) questionnaire existed for pediatric traumatic brain injuries (TBIs). In this revalidation study, the psychometric properties and the validity of the 35-item QOLIBRI-KID/ADO questionnaire in its final German version were examined in 300 children and adolescents. It is the first self-reported TBI-specific tool for measuring pediatric HRQoL in individuals aged between 8 and 17 years. The six-factor model fits the data adequately. The questionnaire's internal consistency was excellent for the total score and satisfactory to excellent for the scale scores. Intraclass correlations indicated good test-retest reliability, and the measure's construct validity was supported by the overlap between the QOLBRI-KID/ADO and the PedsQL, which measures generic HRQoL. The discriminant validity tests showed that older children and girls reported a significantly lower HRQoL than comparison groups, and this was also true of children who were anxious or depressed, or who suffered from post-concussion symptoms, replicating the results of the questionnaire's first developmental study. Our results suggest that the QOLIBRI-KID/ADO is a reliable and valid multidimensional tool that can be used together with the adult version in clinical contexts and research to measure disease-specific HRQoL after pediatric TBI throughout a person's life. This may help improve care, treatment, daily functioning, and HRQoL after TBI.

Sex and Age-at-Injury as Determinants of Social Behavior Outcomes After TBI

While our understanding of long-term disability after traumatic brain injury (TBI) has habitually focused on cognitive and sensorimotor functioning, it is increasingly appreciated that changes in social function for survivors of a brain injury are common and have a profound impact on one's quality of life. In this chapter, we highlight the consequences of TBI on social behavior, taking into account evidence from studies of patient populations as well as from preclinical animal models. After first considering the protracted nature of the development of social behavior across the lifespan, including the neurobiological networks that underlie social functioning, we discuss how TBI results in social behavior impairments and how these manifest. We focus particularly on how age-at-injury influences TBI-induced social impairments, with most of the evidence suggesting age-dependent vulnerability after injury at a younger age. In addition, we explore how biological sex is a key determinant of social behavior impairments after TBI, while gender in humans may also influence the nature and extent of social outcomes. Finally, we identify key knowledge gaps and emphasize the need for further research in the field.

Diet's Impact on Post-Traumatic Brain Injury Depression: Exploring Neurodegeneration, Chronic Blood-Brain Barrier Destruction, and Glutamate Neurotoxicity Mechanisms

Traumatic brain injury (TBI) has a profound impact on cognitive and mental functioning, leading to lifelong impairment and significantly diminishing the quality of life for affected individuals. A healthy blood-brain barrier (BBB) plays a crucial role in guarding the brain against elevated levels of blood glutamate, making its permeability a vital aspect of glutamate regulation within the brain. Studies have shown the efficacy of reducing excess glutamate in the brain as a treatment for post-TBI depression, anxiety, and aggression. The purpose of this article is to evaluate the involvement of dietary glutamate in the development of depression after TBI. We performed a literature search to examine the effects of diets abundant in glutamate, which are common in Asian populations, when compared to diets low in glutamate, which are prevalent in Europe and America. We specifically explored these effects in the context of chronic BBB damage after TBI, which may initiate neurodegeneration and subsequently have an impact on depression through the mechanism of chronic glutamate neurotoxicity. A glutamate-rich diet leads to increased blood glutamate levels when contrasted with a glutamate-poor diet. Within the context of chronic BBB disruption, elevated blood glutamate levels translate to heightened brain glutamate concentrations, thereby intensifying neurodegeneration due to glutamate neurotoxicity.

Quality of Life after Brain Injury in Children and Adolescents (QOLIBRI-KID/ADO)-The First Disease-Specific Self-Report Questionnaire after Traumatic Brain Injury

The subjective impact of the consequences of pediatric traumatic brain injury (pTBI) on different life dimensions should be assessed multidimensionally and as sensitively as possible using a disease-specific health-related quality of life (HRQoL) instrument. The development and psychometrics of the first such self-report questionnaire for children and adolescents after TBI are reported here. Focus group interviews with children, adolescents, and their parents, cognitive debriefing, item pool generation and reduction using Delphi expert panels were performed. The resulting version was psychometrically tested on 300 individuals aged 8-17 years. After item reduction based on factor analyses, differential item functioning, reliability, and validity were investigated. The final 35 items were associated with six scales (Cognition, Self, Daily Life and Autonomy, Social Relationships, Emotions, Physical Problems). Internal consistency and construct validity were satisfactory. Health-related Quality of life (HRQoL) was significantly lower in older and in female participants, as well as those with cognitive disabilities, anxiety, depression and post-concussion symptoms, than in comparative groups. The new QOLIBRI-KID/ADO is a comprehensive, multidimensional, reliable, and valid instrument, comparable in content and items to the QOLIBRI adult version. Therefore, disease-specific HRQoL can now be measured across the lifespan and may support the amelioration of treatment, care, rehabilitation, and daily life of children and adolescents after TBI.

A Multidimensional Approach to Assessing Factors Impacting Health-Related Quality of Life after Pediatric Traumatic Brain Injury

In the field of pediatric traumatic brain injury (TBI), relationships between pre-injury and injury-related characteristics and post-TBI outcomes (functional recovery, post-concussion depression, anxiety) and their impact on disease-specific health-related quality of life (HRQoL) are under-investigated. Here, a multidimensional conceptual model was tested using a structural equation model (SEM). The final SEM evaluates the associations between these four latent variables. We retrospectively investigated 152 children (8-12 years) and 148 adolescents (13-17 years) after TBI at the recruiting clinics or online. The final SEM displayed a fair goodness-of-fit (SRMR = 0.09, RMSEA = 0.08 with 90% CI [0.068, 0.085], GFI = 0.87, CFI = 0.83), explaining 39% of the variance across the four latent variables and 45% of the variance in HRQoL in particular. The relationships between pre-injury and post-injury outcomes and between post-injury outcomes and TBI-specific HRQoL were moderately strong. Especially, pre-injury characteristics (children's age, sensory, cognitive, or physical impairments, neurological and chronic diseases, and parental education) may aggravate post-injury outcomes, which in turn may influence TBI-specific HRQoL negatively. Thus, the SEM comprises potential risk factors for developing negative post-injury outcomes, impacting TBI-specific HRQoL. Our findings may assist healthcare providers and parents in the management, therapy, rehabilitation, and care of pediatric individuals after TBI.

Adverse childhood experiences and traumatic brain injury among adolescents: findings from the 2016-2018 National Survey of Children's Health

Exposure to adverse childhood experiences (ACEs) is a significant public health issue for youth. However, traumatic brain injury (TBI) has been almost entirely overlooked in the ACEs and health outcomes literature, which has largely focused on the significant mental and behavioral health impact of ACEs. The goal the current study is to examine the association between ACEs and TBI among a nationally representative sample of adolescents in the United States and the extent to which ADHD and conduct problems inform this association. To assess this relationship, we use a sample of 42,204 adolescents (ages 12-17 years) in the United States whose caregivers were surveyed during the three most recent cohorts (2016-2018) of the National Survey of Children's Health (NSCH). The results revealed a dose-response relationship between ACEs and TBI, even after accounting for an array of confounding variables. Findings also indicated that associations were of a greater magnitude among youth who are not sports-involved. Supplemental mediation analyses showed that ADHD and conduct problems attenuated associations between ACE exposure and TBI, but only in the absence of youth sports involvement. Given that both ACEs and TBI carry long-term consequences for health and well-being, the findings from this study draw attention to the need for early intervention and prevention programming (e.g. home visiting) that can reduce the prevalence of ACEs and a history of TBI among adolescents.

Predictors of participation and quality of life following major traumatic injuries in childhood: a systematic review

OBJECTIVE

Review the literature on predictors of participation and quality of life in children and young people who sustained a traumatic brain injury (TBI), spinal cord injury (SCI), and/or multi-trauma in a motor vehicle or other accident or trauma.

DESIGN

This systematic review was conducted and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The protocol was registered on PROSPERO (registration number CRD42020131698). Electronic databases were searched for studies published between January 2000 and August 2020. Prospective and retrospective cohort studies were considered and risk of bias was assessed using the Quality In Prognosis Studies (QUIPS) tool.

RESULTS

The search yielded 5771 articles of which 30 studies met the inclusion criteria. Nineteen studies included patients with TBI and 11 with SCI. No studies of patients with multi-trauma met criteria. Evidence was found for associations with various factors (e.g., injury severity, level of education, mental health problems), although these findings are limited due to the quality of the studies (5 studies moderate and 25 high risk of bias).

CONCLUSION

Research on predictors of participation and quality of life following major traumatic injuries in childhood is lacking. More methodologically sound prospective, longitudinal studies are needed across different injury groups to further elucidate predictors of outcome.IMPLICATIONS FOR REHABILITATIONWhile long-term participation and quality of life is influenced by injury characteristics (i.e., injury severity), a number of potential modifiable factors can be targeted to improve outcomes following traumatic injuries in childhood.Young people should be provided with support to stay in school and pursue further education.Early intervention and prevention of mental health problems may improve long-term outcomes.Better management of ongoing medical problems and greater support for functional independence may improve participation.

[Formula: see text] Investigation of children and adolescents' mood and self-concept after acquired brain injury

Few studies have examined the self-reported mental health of children with an acquired brain injury (ABI). The current study aimed to: 1) identify levels of child-reported depressive and anxiety symptoms and poor self-concept, 2) investigate demographic and injury-related factors associated with children's mood and self-concept, and 3) examine associations between children's self-reported mental health and parents' reports of children's emotional and behavioral functioning in children specifically with traumatic brain injury (TBI). 122 children (66% male) aged 8-16 years with ABI of mixed etiology were consecutively recruited through an outpatient rehabilitation clinic. Children were administered the Beck Youth Inventories - Second Edition, and parents completed the Adaptive Behavior Assessment System and the Child Behavior Checklist (CBCL). Relative to the norms, 16.4% of children scored in the clinical range for the depression and anxiety scales, and 24.6% reported clinically low self-concept. Children with lower functional status had greater anxiety symptoms. Older children (13-16 years) reported significantly higher depressive and anxiety symptoms and lower self-concept than younger children (8-12 years). A significant interaction between age and sex indicated that older girls reported greater depressive and anxiety symptoms than younger girls whereas no age-based differences were found for boys. Parent-reported total emotional and behavioral problems were positively associated with children's self-reported depressive and anxiety symptoms and were negatively correlated with self-concept. These findings indicate that adolescents, particularly girls, may be at heightened risk of poor mental health following ABI. Further research investigating the reasons for these demographic differences may inform developmentally sensitive interventions.

Effects of Chronic Brain Injury on Quality of Life: A Study in Patients With Left- or Right-Sided Lesion

Objectives

To test the hypothesis that quality of life (QOL) is made up of different components, and each of these has different anatomic and demographic contributors.

Design

Questionnaire-based study.

Setting

Center for Cognitive Neuroscience, University of Pennsylvania.

Participants

People with chronic brain injury (N=52) volunteered for the study. After excluding patients with severe communication deficits, bilateral lesions, and incomplete data, 42 patients with focal lesions were included in the final study: 22 patients with left hemisphere injury (LHI) (9 women and 13 men; mean age ± SD, 60.6±11.2y [range: 36-83]; mean chronicity ± SD, 11.5±4.2y) and 20 patients with right hemisphere injury [RHI] (16 women and 4 men; mean age ± SD [62.7±12.8y] [range: 31-79]; mean chronicity ± SD 10.1±4.3y).

Interventions

Not applicable.

Main Outcome Measures

We administered the RAND36-Item Health Survey (RAND-Version-1.0), Stroke Impact Scale (version 3.0), Positive Affect and Negative Affect Scale, and Distress Thermometer to measure QOL in LHI and RHI patients. Exploratory factor analysis with principal component method reduced these measures to 5 factors, roughly categorized as-(1) physical functioning; (2) general health; (3) emotional health; (4) social functioning; and (5) cognitive functioning. Exploratory analyses attempted to relate these factor scores to demographic variables, neuroanatomical data, and neuropsychological measures.

Results

Physical functioning was the biggest contributor to reduced QOL, explaining 32.5%, of the variance. Older age, less education, and larger lesion size predicted poorer physical functioning (P<.001). Age also affected emotional health. (P=.019). Younger patients reported poorer emotional health than older patients. LHI patients reported less satisfaction with their cognitive functioning (P=.009) and RHI patients with their physical functioning (P=.06). Exploratory neuroanatomical analyses hinted at brain areas that may be associated with the perception of disability in each QOL component.

Conclusions

QOL is composed of 5 components. Clinical and demographic factors appear to differentially affect these aspects of patients' perceived QOL, providing hypotheses for further testing and suggesting potential relations for therapeutic interventions to consider.

Self- and parent-reported Quality of Life 7 years after severe childhood traumatic brain injury in the Traumatisme Grave de l'Enfant cohort: associations with objective and subjective factors and outcomes

PURPOSE

To investigate self- and parent-reported Health-Related Quality-of-Life (HRQoL) and their associations after severe childhood traumatic brain injury (TBI) in the Traumatisme Grave de l'Enfant (TGE) cohort.

METHODS

Self- (n = 34) and/or parent-reports (n = 25) of HRQoL were collected for 38 participants (age 7-22 years) 7 years after severe childhood TBI. The collected data included sociodemographic characteristics, injury severity indices, and overall disability and functional outcome at 3-months, 1- and 2-years post-injury. At 7-years post-injury, data were collected in the TBI group and in a control group (n = 33): overall disability (Glasgow Outcome Scale Extended), intellectual ability (IQ), and questionnaires assessing HRQoL (Pediatric Quality of Life Inventory), executive functions (Behavior Rating Inventory of Executive Functions), behavior (Child Behavior Checklist), fatigue (Multidimensional Fatigue Scale) and participation (Child and Adolescent Scale of Participation).

RESULTS

Parent- and self-reports of HRQoL were significantly lower in the TBI group than in the control group. Parent-rated HRQoL was not associated with objectively assessed factors, whereas self-reported HRQoL was associated with gender (worse in females) and initial functional outcome. All questionnaire scores completed by the same informant (self or parent) were strongly inter-correlated.

CONCLUSIONS

Reported HRQoL 7-years after severe childhood TBI is low compared to controls, weakly or not-related to objective factors, such as injury severity indices, clinically assessed functional outcomes, or IQ, but strongly related to reports by the same informant of executive deficits, behavior problems, fatigue, and participation.

Youth and young adults with acquired brain injury transition towards work-related roles: a qualitative study

PURPOSE

The purpose of this research was to explore the experiences of youth and young adults with acquired brain injury as they transition towards work-related roles. Little is known about employment experiences among this age group. Understanding their perspectives can inform programs and clinical practice.

MATERIALS AND METHODS

A descriptive qualitative design, including semi-structured interviews with 14 participants (8 females; 6 males) was used. Interviews were transcribed verbatim and analyzed using an open-coding, thematic approach.

RESULTS

Three major themes emerged related to the experience of work-related roles: (1) getting to know the new me; (2) navigating support systems; and (3) taking control of my experience. Some participants used coping strategies to acquire and/or maintain work-related roles, while others felt limited by their condition.

CONCLUSIONS

A variety of work-related roles, people, and environments directly and indirectly influenced the work-related transition of youth and young adults with acquired brain injury. Individuals expressed the importance of acquired brain injury awareness in informing others about their impairments. In fact, a lack of acquired brain injury awareness was often a main reason for receiving less than adequate support and accommodations. Without an understanding of acquired brain injury, people in the lives of these individuals were unable to perceive the legitimacy of acquired brain injury-related impairments. Implications for rehabilitation The purpose of this study is to understand the experiences of youth and young adults with acquired brain injury as they transition into work-related roles. Using these experiences as a guideline can promote acquired brain injury awareness, and contribute to how current interventions are designed and delivered. Clinicians should ensure that youth and young adults with acquired brain injury have access to the resources they need to maximize their independence. Healthcare professionals can play a pivotal role in relaying important acquired brain injury-related education, implementing suitable treatment plans, and providing them with effective tips to help them through their transition. A healthy transition to work-related roles should include ample social support and communication, acquired brain injury-related information that informs the community of acquired brain injury impairments, needs, and recovery trajectory, as well as adequate and consistent coordination within and between the person and the environment.

Social and Behavioral Outcomes following Childhood Traumatic Brain Injury: What Predicts Outcome at 12 Months Post-Insult?

This study sought to investigate social and behavioral outcomes 12 months following childhood traumatic brain injury (TBI) and to identify predictors of these outcomes. The study also compared rates of impairment in social and behavioral outcomes at 12 months post-injury between children with TBI and a typically developing (TD) control group. The study comprised 114 children ages 5.5 to 16.0 years, 79 with mild, moderate, or severe TBI and 35 TD children, group-matched for age, sex and socio-economic status. Children with TBI were recruited via consecutive hospital admissions and TD children from the community. Social and behavioral outcomes were measured via parent-rated questionnaires. Analysis of covariance models identified a significant mean difference between the mild and moderate groups for social problems only, but the moderate and severe TBI groups showed a higher rate of impairment, particularly in externalizing problems. Pre-injury function, injury severity, parent mental health, and child self-esteem all contributed significantly to predicting social and behavioral outcomes. Both injury and non-injury factors should be considered when identifying children at risk for long-term difficulties in social and behavioral domains.

Association between Hyperglycaemia with Neurological Outcomes Following Severe Head Trauma

INTRODUCTION

Head Trauma (HT) is a major cause of death, disability and important public health problem. HT is also the main cause of hyperglycaemia that can increase mortality.

AIM

The aim of this study was to assess the correlation between hyperglycaemia with neurological outcomes following severe Traumatic Brain Injury (TBI).

MATERIALS AND METHODS

This is a descriptive and correlation study that was carried out at the Imam Khomeini Hospital affiliated with Ilam University of Medical Sciences, Ilam, IR, during March 2014-March 2015 on patients with severe TBI. Data were collected from the patient records on mortality, Intensive Care Unit (ICU) length of stay, hospital length of stay, admission GCS score, Injury Severity Score (ISS), mechanical ventilation, Ventilation Associated Pneumonia (VAP) and Acute Respiratory Distress Syndrome (ARDS). Random Blood Sugar (RBS) level on admission was recorded. Patients with diabetes mellitus (to minimize the overlap between acute stress hyperglycaemia and diabetic hyperglycaemia) were excluded.

RESULTS

About 34(40%) of patients were admitted with hyperglycaemia (RBS ≥ 200 mg/dl) over the study period. The mortality rate, length of ICU stay, hospital stay, ISS and VAP & ARDS in patients with RBS levels ≥ 200 mg was significantly higher than patients with RBS levels below ≤ 200mg (p<0.05, p<0.001). A significant correlation was found between RBS with GCS arrival, length of ICU stay, length of hospital stay, ISS, mechanical ventilation and VAP & ARDS (p<0.05, p< 0.001). RBS is a predicate factor for ISS (p <0.05, OR : 1.36), GCS (p <0.001, OR : 1.69), mechanical ventilation (p< 0.05, OR : 1.27), VAP & ARDS (p <0.001, OR : 1.68), length of ICU stay (p <0.001, OR : 1.87) and length of hospital stay (p <0.05, OR : 1.24).

CONCLUSION

Hyperglycaemia after severe TBI (RBS ≥ 200) is associated with poor outcome. It can be a predictive factor for mortality rate, ICU stay, GCS arrival, VAP & RDS, hospital stay and ISS. Management of hyperglycaemia with insulin protocol in cases with value >200mg/dl, is critical in improving the outcome of patients with TBI.

Outcome and Predicting Factor Following Severe Traumatic Brain Injury: A Retrospective Cross-Sectional Study

INTRODUCTION

Severe traumatic brain injury (TBI) is a major and challenging problem in critical care medicine.

AIM

To assess the outcome and predicting factor following severe TBI.

MATERIALS AND METHODS

This is a retrospective and cross-sectional study. Data were collected from two sections; one section consisting of a questionnaire answered by the patients and other section from the patient records. The instruments used included the Glasgow Outcome Scale (GOS), SF-36 and the Hospital Anxiety and Depression Scale (HAD).

RESULTS

The mortality rate of the patients was 46.2%. The quality of life (QOL) of the patients in most dimension were impaired and (58%) of patients had unfavourable QOL. About (37.5%) of patients with anxiety and (27.5%) had a depression. A significant correlation was found between age, GCS arrival, length of ICU stay, mechanical ventilation, VAP & ARDS and pupil reactivity with QOL, GOS, HAD-A and HAD-D (p<0.05, p< 0.001). GCS arrival a predicate factor for QOL and GOS (p <0.001, OR: 1.75, 1.94 respectively); length of ICU stay a predicate factor for QOL and GOS (p <0.05, OR : 1.11, 1.28 respectively); mechanical ventilation a predicate factor for GOS (p <0.001, OR : 1.78); ventilation associated pneumonia (VAP) & acute respiratory distress syndrome (ARDS) and pupil reactivity a predicate factor for GOS (p <0.05, OR : 1.36; p<0.001, OR: 1.94 respectively). The GCS arrival and ICU stay a predicate factor for HAD-A (p<0.05, OR: 1.73, 1.38 respectively).

CONCLUSION

With respect to results advanced in pre hospital, medical and surgical care for the decrease in mortality rates of Head trauma (HT), the use of trauma triage tools and strict enforcement of traffic rules are necessary.

Mild Concussion, but Not Moderate Traumatic Brain Injury, Is Associated with Long-Term Depression-Like Phenotype in Mice

Mild traumatic brain injuries can lead to long-lasting cognitive and motor deficits, increasing the risk of future behavioral, neurological, and affective disorders. Our study focused on long-term behavioral deficits after repeated injury in which mice received either a single mild CHI (mCHI), a repeated mild CHI (rmCHI) consisting of one impact to each hemisphere separated by 3 days, or a moderate controlled cortical impact injury (CCI). Shams received only anesthesia. Behavioral tests were administered at 1, 3, 5, 7, and 90 days post-injury (dpi). CCI animals showed significant motor and sensory deficits in the early (1-7 dpi) and long-term (90 dpi) stages of testing. Interestingly, sensory and subtle motor deficits in rmCHI animals were found at 90 dpi. Most importantly, depression-like behaviors and social passiveness were observed in rmCHI animals at 90 dpi. These data suggest that mild concussive injuries lead to motor and sensory deficits and affective disorders that are not observed after moderate TBI.

Psychological Outcome in Young Survivors of Severe TBI: A Cross-Informant Comparison

Objective. To investigate the psychological outcome and the agreement between self-ratings and proxy-ratings in young individuals after severe traumatic brain injury (TBI). Methods. Twenty pairs of former patients who sustained a severe TBI in their adolescence or early adulthood and their significant others (SOs) were contacted around 66 months after injury to complete a measure of psychological and behavioral problems. The Adult Self-Report 18–59 and the Adult Behavior Checklist 18–59 were used. Results. Results showed significant differences compared to the normative sample in the domains withdrawal, attention, and intrusive and internalizing problems. Good or excellent levels of agreement were found between the self-rating and the proxy-rating in overt areas such as somatic complaints and aggressive and intrusive behavior. Fair or poor levels of agreement were found in nonovert areas such as anxiety and depression, withdrawal, thought and attention problems, and personal strength. Conclusion. The findings show that young patients experience psychological dysfunction. Our study suggests that the use of either a self-rating or a proxy-rating would be appropriate for evaluating overt domains, regarding the good to excellent levels of agreement. However, in nonovert domains, such as withdrawal and attention, an additional proxy-rating from a SO could provide supplementary information and build a more complete objective assessment.

Transcranial magnetic stimulation facilitates neurorehabilitation after pediatric traumatic brain injury

Traumatic brain injury (TBI) is the leading cause of death and disability among children in the United States. Affected children will often suffer from emotional, cognitive and neurological impairments throughout life. In the controlled cortical impact (CCI) animal model of pediatric TBI (postnatal day 16-17) it was demonstrated that injury results in abnormal neuronal hypoactivity in the non-injured primary somatosensory cortex (S1). It materializes that reshaping the abnormal post-injury neuronal activity may provide a suitable strategy to augment rehabilitation. We tested whether high-frequency, non-invasive transcranial magnetic stimulation (TMS) delivered twice a week over a four-week period can rescue the neuronal activity and improve the long-term functional neurophysiological and behavioral outcome in the pediatric CCI model. The results show that TBI rats subjected to TMS therapy showed significant increases in the evoked-fMRI cortical responses (189%), evoked synaptic activity (46%), evoked neuronal firing (200%) and increases expression of cellular markers of neuroplasticity in the non-injured S1 compared to TBI rats that did not receive therapy. Notably, these rats showed less hyperactivity in behavioral tests. These results implicate TMS as a promising approach for reversing the adverse neuronal mechanisms activated post-TBI. Importantly, this intervention could readily be translated to human studies.

Long-Term Behavioral Outcomes after a Randomized, Clinical Trial of Counselor-Assisted Problem Solving for Adolescents with Complicated Mild-to-Severe Traumatic Brain Injury

Family problem-solving therapy (FPST) has been shown to reduce behavior problems after pediatric traumatic brain injury (TBI). It is unclear whether treatment gains are maintained. We sought to evaluate the maintenance of improvements in behavior problems after a Web-based counselor-assisted FPST (CAPS) intervention compared to an Internet resource comparison (IRC) intervention provided to adolescents within the initial year post-TBI. We hypothesized that family socioeconomic status, child educational status, and baseline levels of symptoms would moderate the efficacy of the treatment over time. Participants included 132 adolescents ages 12-17 years who sustained a complicated mild-to-severe TBI 1-6 months before study enrollment. Primary outcomes were the Child Behavior Checklist Internalizing and Externalizing Totals. Mixed-models analyses, using random intercepts and slopes, were conducted to examine group differences over time. There was a significant group×time×grade interaction (F(1,304)=4.42; p=0.03) for internalizing problems, with high school-age participants in CAPS reporting significantly lower symptoms at 18 months postbaseline than those in the IRC. Post-hoc analyses to elucidate the nature of effects on internalizing problems revealed significant group×time×grade interactions for the anxious/depressed (p=0.03) and somatic complaints subscales (p=0.04). Results also indicated significant improvement over time for CAPS participants who reported elevated externalizing behavior problems at baseline (F(1, 310)=7.17; p=0.008). Findings suggest that CAPS may lead to long-term improvements in behavior problems among older adolescents and those with pretreatment symptoms.

Does what we measure matter? Quality-of-life defined by adolescents with brain injury

OBJECTIVES

To determine if domains included in popular measurement systems (e.g. the Peds QL™) reflect the adolescent survivor of a brain injury's sense of QoL and explore this relationship in reference to an emerging model of wellbeing in the adolescent with TBI.

METHODS

Mixed methods; adolescent QoL assessed using the PedsQL™ self-report and a semi-structured interview created by the lead author. Adolescent self-report was compared to adolescent narratives.

RESULTS

Ten adolescents participated. Adolescent PedsQL™ total was within normal limits. Adolescents reported that changes identified by the PedsQL were not important and did not impact on their sense of QoL. The importance on social components of QoL-as opposed to cognitive-provide additional support of the emerging model of wellbeing in adolescents with TBI.

CONCLUSIONS

The PedsQL can identify changes post-TBI, but fails to consider whether these changes are relevant to the adolescent. Alternate methods of exploring QoL-which emphasize the interaction of social networks and friendships, should be considered to avoid an oblique view of QoL outcomes after TBI.
