Abstract
Objective There is preliminary evidence that children after traumatic brain injury (TBI) have accelerated long-term forgetting (ALF), i.e., an adequate learning and memory performance in standardized memory tests, but an excessive rate of forgetting over delays of days or weeks. The main aim of this study was to investigate episodic memory performance, including delayed retrieval 1 week after learning, in children after mild TBI (mTBI). Methods This prospective study with two time-points (T1: 1 week after injury and T2: 3-6 months after injury), included data of 64 children after mTBI and 57 healthy control children aged between 8 and 16 years. We assessed episodic learning and memory using an auditory word learning test and compared executive functions (interference control, working memory, semantic fluency and flexibility) and divided attention between groups. We explored correlations between memory performance and executive functions. Furthermore, we examined predictive factors for delayed memory retrieval 1 week after learning as well as for forgetting over time. Results Compared to healthy controls, patients showed an impaired delayed recall and recognition performance 3-6 months after injury. Executive functions, but not divided attention, were reduced in children after mTBI. Furthermore, parents rated episodic memory as impaired 3-6 months after injury. Additionally, verbal learning and group, but not executive functions, were predictive for delayed recall performance at both time-points, whereas forgetting was predicted by group. Discussion Delayed recall and forgetting over time were significantly different between groups, both post-acutely and in the chronic phase after pediatric mTBI, even in a very mildly injured patient sample. Delayed memory performance should be included in clinical evaluations of episodic memory and further research is needed to understand the mechanisms of ALF.

Abstract
BACKGROUND Childhood traumatic brain injury (TBI) can result in impairments in learning, cognition, and behaviour; all of which can adversely influence educational outcomes. Schools can play a crucial role in rehabilitation, therefore it is important that evidence-based supports are available in these settings. OBJECTIVE The aim of this systematic review was to evaluate the effectiveness of school-based supports and interventions available following childhood TBI. METHODS A comprehensive search strategy involved eight research databases, grey literature, and backward reference searching. RESULTS The search identified 19 studies, reporting on sixteen distinct interventions, which used a variety of person-centred and systemic approaches, and typically contained multiple components, including: psychoeducation, behavioural scripts, and attention training. While offering some indication for future directions in intervention, the evidence base for individual interventions was typically limited, and does not take account of cost or issues in sustainability. CONCLUSION While there appears to be great potential to support students who may otherwise not gain access to services, there is insufficient evidence to guide widespread policy or practice change without further research. Greater collaboration between researchers, clinical practitioners, and educators is necessary to ensure that all interventions developed are robustly evaluated and disseminated.

Abstract
Youth with a history of traumatic or non-traumatic acquired brain injury are at increased risk for long-lasting cognitive, emotional, behavioral, social, and physical sequelae post-injury. Such sequelae have great potential to negatively impact this population’s academic functioning. Consistently, poorer academic achievement and elevated need for educational supports have been well-documented among youth with a history of acquired brain injury. The current paper reviews the literature on neuropsychological, psychiatric, and academic outcomes of pediatric acquired brain injury. A discussion of special education law as it applies to this patient population, ongoing limitations within the field, and a proposal of solutions are also included.

Abstract
AIM The Child Behavior Checklist (CBCL) includes several sleep items. We aimed to examine the convergent validity of CBCL sleep scores with validated sleep measures, and to explore their functional correlates. METHODS This cross-sectional study included 44 children with moderate to severe TBI, aged 6-15 years. Parents completed the CBCL and Sleep Disturbance Scale for Children (SDSC), and children wore actigraphy watches. RESULTS We found significant, albeit differential, associations between CBCL and SDSC sleep scores. Specifically: (i) "trouble sleeping" with SDSC total score, (ii) "trouble sleeping" and "nightmares" with SDSC initiating and maintaining sleep, (iii) "talks/walks in sleep" with SDSC arousal, and (iv) "overtired," "sleeps more" and CBCL sleep composite with SDSC excessive somnolence. The CBCL item "sleeps less" was the only significant predictor of functioning; children who slept less had lower social competence. No associations were found between CBCL sleep scores and actigraphy. CONCLUSIONS The CBCL does not provide a comprehensive assessment of sleep disturbances in children with moderate to severe TBI. Nevertheless, certain CBCL sleep items demonstrate initial convergent validity with subscales of the SDSC assessing select types of sleep disturbances. The CBCL may be useful in research and clinical situations when administration of more comprehensive assessment sleep tools is not viable.

Quality of family environment predicts child perceptions of competence 12 months after pediatric traumatic brain injury. Ann Phys Rehabil Med 2021; 65:101606. [PMID: 34780994 DOI: 10.1016/j.rehab.2021.101606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 10/12/2021] [Accepted: 10/17/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND . Demographic and environmental factors can affect child recovery after traumatic brain injury (TBI); however, little is known about their role in predicting child perceptions of competence (i.e., subjective judgments of ability or a sense of adequacy). OBJECTIVES . This prospective, cohort study examined the contribution of participant sex, age at assessment, socioeconomic status, parent-reported change in academic performance post-injury, and the quality of a child's relationship with their family (i.e., family affective involvement, intimacy, integration, and the nature of family roles) to child perceptions of global and academic competence 12 months after pediatric TBI. METHODS . Participants included 127 children, 84 with a TBI (53 mild, 31 moderate-severe TBI; injury age: 5-15 years) and 43 age-matched typically developing (TD) controls. Children rated their perceptions of global and academic competence and degree of family intimacy and integration. Parents completed questionnaires measuring socioeconomic status, family affective involvement, and the nature of family roles. Parents also indicated whether they perceived a change in their child's post-injury academic performance. RESULTS . Child perceptions of academic competence were significantly lower for children with moderate-severe TBI relative to TD children. In contrast, child perceptions of global competence were comparable between TBI and TD control groups. Socioeconomic status, age at assessment, parent-reported relative change in academic performance post-TBI, and family roles were associated with child perceptions of academic competence. Degree of family integration was the sole predictor of child perceptions of global competence. CONCLUSIONS . Child perceptions of academic competence are vulnerable to the effects of moderate-severe TBI, particularly among older children and those from low socioeconomic backgrounds. Well-defined family roles for handling family functions and greater integration of family units might enhance perceptions of global and academic competence in children with TBI.

Abstract
Abstract
Background:
Attention and memory deficits are common following paediatric acquired brain injury (ABI). However, there are few evidence-based interventions to improve these domains and benefit the everyday life of children post-injury. The Amsterdam Memory and Attention Training for children (Amat-c) has been translated from Dutch to English and shown to improve attention and memory skills in children following ABI. This protocol describes a study to expand accessibility of the program by using online, clinician-supported delivery with children post-ABI.
Method/design:
The study is a randomized controlled trial. Participants will be 40 children aged 8–16 a minimum of one-year post-ABI. Participants in the treatment group will complete 18 weekly sessions of the Amat-c program with weekly online clinician support. Participants in the active-control group will be administered ABI psychoeducation via a booklet for parents, with weekly online clinician contact. Attention and memory will be assessed at three time points up to six months post-intervention.
Results:
Analysis will be repeated measures multivariate planned comparisons; using the Statistical Package for the Social Sciences (IBM SPSS Statistics) General Linear Model procedure will compare pre- and post-intervention and six-month follow-up outcomes.
Discussion:
If shown efficacious in improving attention and memory, our team will then take a key role in implementing Amat-c into clinical care.

Abstract
OBJECTIVE To report preliminary empirical data on a novel, developmentally appropriate, observational postconcussive symptoms inventory for infants, toddlers, and preschoolers. SETTING Emergency departments of 2 tertiary, urban pediatric hospitals. PARTICIPANTS Ninety-eight children (0-8 years of age; mean age at injury = 33.00, SD = 24.7 months) with mild traumatic brain injury (concussion) divided into younger (0-2 years) and older (3-8 years) age groups. DESIGN Observational study. MAIN MEASURE The Report of Early Childhood Traumatic Injury Observations & Symptoms (REACTIONS) documents 17 postconcussive symptoms representing observable manifestations thereof and was completed by parents in the acute (24-48 hours; n = 65), subacute (7-14 days; n = 78), and/or persistent phase (25-35 days; n = 72) post-mild traumatic brain injury. RESULTS Different patterns of postconcussive symptoms were reported by age group, with behavioral manifestations particularly salient in younger children. More children younger than 2 years had sleep and comfort-seeking symptoms at each of the 3 postinjury time points. CONCLUSION Postconcussive symptoms may manifest differently after mild traumatic brain injury sustained during early childhood. To fully understand and address their presence and evolution, developmentally sound measures such as the REACTIONS inventory are required.

Abstract
OBJECTIVE To examine the efficacy of an online traumatic brain injury (TBI) professional development intervention, In the Classroom After Concussion: Best Practices for Student Success. DESIGN A randomized controlled trial with a sample of 100 general educators, who were randomly assigned to the In the Classroom Web site (treatment group) or the LEARNet Web site (control group). Participants completed the pretest, accessed the In the Classroom or LEARNet site and the posttest and completed follow-up assessments 60 days after posttest. MEASURES (1) Knowledge of effective strategies for working with students with TBI; (2) knowledge application; (3) self-efficacy in handling situations presented in text and video scenarios, and (4) a standardized self-efficacy measure. RESULTS On the posttest assessment, In the Classroom educators showed significantly greater gains in knowledge (P < .0001, d = 1.36 [large effect]), TBI knowledge application (P = .0261, d = 0.46), and general self-efficacy (P = .0106, d = 0.39) than the LEARNet controls. In the Classroom educators maintained significant gains in knowledge (P = .001, d = 0.82) and general self-efficacy (P = .018, d = 0.38) but not in TBI knowledge application (P = .921, d = 0.02). CONCLUSION Given the prevalence of TBI, it is important to develop evidence-based, cost-effective approaches to knowledge transfer and exchange in TBI professional development. In the Classroom is one such approach.

Abstract
Background: Each year ∼700 000 U.S. children ages 0-19 years sustain a traumatic brain injury. Children who experience brain injury are at risk for impairments in executive function, processing speed, cognition, memory, attention, and behavior which can lead to school failure. However, few teachers or other educational professionals receive training on effectively working with students who have traumatic brain injury (TBI). The purpose of this study was to examine the efficacy of an online traumatic brain injury professional development intervention, In the Classroom after Concussion: Best Practices for Student Success.Methods: This quasi-experimental study examined the effects of online traumatic brain injury professional development (In the Classroom after Concussion: Best Practices for Student Success) on educator knowledge, knowledge application, and self-efficacy in a practitioner setting with a sample of 81 educators from all professional backgrounds. Participants completed the pretest, accessed the In the Classroom training and posttest, and completed follow-up assessments 30 days after the posttest. Measures: (1) knowledge of effective strategies for working with students with TBI; (2) knowledge application; (3) self-efficacy in handling situations presented in text and video scenarios, and (4) a standardized measure of educator self-efficacy.Results: On the posttest assessment, educators showed significant gains in knowledge (p = 0.001, r = 0.62), knowledge application (p = 0.001, r = 0.63), and self-efficacy (p = 0.008, r = 0.29). At 30-day follow up, educators maintained significant gains in knowledge (p = 0.001, r = 0.62) and self-efficacy (p value = 0.008, r = 0.28), but not in knowledge application.Conclusion: Given the prevalence of traumatic brain injury, it is important to develop evidence-based, cost-effective approaches to knowledge transfer and exchange in traumatic brain injury professional development. In the Classroom is one such approach.Implications for rehabilitationWithout training in TBI, educators will be poorly prepared to monitor students' post-injury challenges and to address learning and behavioral challenges as they occur.Given the prevalence of TBI, it is important to develop evidence-based, cost-effective approaches to knowledge transfer and exchange in TBI professional development. In the Classroom is one such approach.

Abstract
Traumatic brain injury (TBI) results in heterogeneous patterns of neuropsychological impairment. This study investigated heterogeneity in executive function (EF) using the Comprehensive Trail Making Test (CTMT) to evaluate 121 children and adolescents with TBI and 121 matched normal controls. The TBI group performed approximately two standard deviations below controls. Cluster analyses indicated that a three-cluster solution best classified the TBI group and a four-cluster solution best classified controls. Greater impairment in EF was associated with lower intellectual, achievement, and neuropsychological test performance in the TBI group. Results suggest that EF deficits reflected in CTMT performance may be useful for classifying severity of TBI.

Abstract
OBJECTIVE The present study utilized ecobehavioral assessment to examine classroom functioning several years following early childhood traumatic brain injury (TBI) or orthopedic injury (OI) and its association with injury factors, neuropsychological abilities, and academic performance. METHOD Participants included 39 children with moderate to severe TBI and 51 children with OI sustained between ages 3 and 7 years. At 7.2 (± 1.3) years post injury, ecobehavioral assessment was used to examine classroom functioning. Additional outcomes included neuropsychological tests, parent and teacher ratings of dysexecutive behavior, and teacher ratings of academic performance. Groups were compared on measures controlling for demographic characteristics, and associations among outcomes were examined using linear regression. RESULTS Children with TBI showed lower academic engagement relative to children with OI, as well as more frequent individual teacher attention for children with more severe injuries. For children with TBI, difficulties in classroom functioning were associated with lower cognitive flexibility and higher parent and teacher ratings of dysexecutive behavior. Lower scores on a test of fluid reasoning and a greater frequency of individual teacher attention were also associated with lower academic performance in children with TBI. CONCLUSIONS Difficulties in classroom functioning are evident several years after early childhood TBI and were associated with greater injury severity, neuropsychological weaknesses, and poorer academic performance. Children with impaired cognitive flexibility and fluid reasoning skills were at greatest risk for these difficulties and associated weaknesses in academic performance. Instructional interactions may be a potential target for intervention to promote academic progress in at-risk children. (PsycINFO Database Record

Abstract
OBJECTIVE This study examined how the family environment predicts long-term academic and behavioral functioning in school following traumatic brain injury (TBI) in early childhood. METHOD Using a concurrent cohort, prospective design, 15 children with severe TBI, 39 with moderate TBI, and 70 with orthopedic injury (OI) who were injured when they were 3-7 years of age were compared on tests of academic achievement and parent and teacher ratings of school performance and behavior on average 6.83 years postinjury. Soon after injury and at the longer term follow-up, families completed measures of parental psychological distress, family functioning, and quality of the home environment. Hierarchical linear regression analyses examined group differences in academic outcomes and their associations with measures of the early and later family environment. RESULTS The severe TBI group, but not the moderate TBI group, performed worse than did the OI group on all achievement tests, parent ratings of academic performance, and teacher ratings of internalizing problems. Higher quality early and late home environments predicted stronger academic skills and better classroom behavior for children with both TBI and OI. The early family environment more consistently predicted academic achievement, whereas the later family environment more consistently predicted classroom functioning. The quality of the home environment predicted academic outcomes more strongly than did parental psychological distress or family functioning. CONCLUSION TBI in early childhood has long-term consequences for academic achievement and school performance and behavior. Higher quality early and later home environments predict better school outcomes for both children with TBI and children with OI. (PsycINFO Database Record

Abstract
OBJECTIVE To examine the prevalence of academic need, academic service utilization, and unmet need as well as factors associated with academic service utilization 6.8 years after traumatic brain injury (TBI) in early childhood. METHODS Fifty-eight (16 severe, 14 moderate, 28 complicated mild) children with TBI and 72 children with orthopedic injury (OI) completed the long-term follow-up 6.8 years after injury in early childhood (ages 3-7 years). Injury group differences in rates of need for academic services, academic service utilization, and unmet need as well as factors associated with service utilization and unmet need were examined. RESULTS Students with moderate and severe TBI had significantly greater rates of need than those with OI. A greater proportion of the severe TBI sample was receiving academic services at long-term follow-up than the OI and complicated mild groups however, among those with an identified need, injury group did not affect academic service utilization. Below average IQ/achievement scores was the only area of need predictive of academic service utilization. Rates of unmet need were high and similar across injury groups (46.2%-63.6%). CONCLUSION The need for academic services among patients who sustained a TBI during early childhood remains high 6.8 years post injury. Findings underscore the importance of continued monitoring of behaviors and academic performance in students with a history of early childhood TBI. This may be especially true among children with less severe injuries who are at risk for being underserved.

Abstract
An evaluation was made of the outcome of a day hospital rehabilitation program for children who experienced an acquired neurological illness, mainly traumatic brain injury. Participants were administered neuropsychological and academic evaluations upon entry to the program, immediately upon discharge and several months after discharge Repeated measures ANOVA results for variables selected from the Reynolds Intellectual Assessment and the Delis-Kaplan Executive Function System found that comparisons showed significant (≥p < .01) improvement occurred between the first and second assessment, generally with large effect sizes. There were some nonsignificant decrements in performance between the discharge and follow-up assessments. A correlational analysis showed that while the association between cognitive function and academic achievement was robust, correlation coefficients did not differ in strength before and following rehabilitation. The study demonstrates significant improvement in children with acquired neurological disorders following rehabilitation.

Abstract
PURPOSE Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in children. Preventing secondary injury by controlling physiological parameters (e.g. intracranial pressure [ICP], cerebral perfusion pressure [CPP] and brain tissue oxygen [PbtO2]) has a potential to improve outcome. Low PbtO2 is independently associated with poor clinical outcomes in both adults and children. However, no studies have investigated associations between low PbtO2 and neuropsychological and behavioural outcomes following severe pediatric TBI (pTBI). METHODS We used a quasi-experimental case-control design to investigate these relationships. A sample of 11 TBI patients with a Glasgow Coma Scale score ≤8 who had PbtO2 and ICP monitoring at the Red Cross War Memorial Children's Hospital underwent neuropsychological evaluation ≥1 year post-injury. Their performance was compared to that of 11 demographically matched healthy controls. We then assigned each TBI participant into one of two subgroups, (1) children who had experienced at least one episode of PbtO2 ≤ 10 mmHg or (2) children for whom PbtO2 > 10 mmHg throughout the monitoring period, and compared their results on neuropsychological evaluation. RESULTS TBI participants performed significantly more poorly than controls in several cognitive domains (IQ, attention, visual memory, executive functions and expressive language) and behavioural (e.g. externalizing behaviour) domains. The PbtO2 ≤ 10 mmHg group performed significantly worse than the PbtO2 > 10 mmHg group in several cognitive domains (IQ, attention, verbal memory, executive functions and expressive language), but not on behavioural measures. CONCLUSION Results demonstrate that low PbtO2 may be prognostic of not only mortality but also neuropsychological outcomes.

Abstract
The aim of this review is to systematically examine the literature concerning multicomponent working memory (WM)-comprising a central executive (CE), two storage components (phonological loop, PL and visuo-spatial sketchpad, VSSP), and episodic buffer (EB)-in pediatric traumatic brain injury (TBI). Electronic searches were conducted of MEDLINE, PsychINFO and EMBASE up to October 2014 with the inclusion criteria of children and adolescents with TBI, and quantitative methods to assess at least one component of WM. Meta-analytic procedures calculated pooled effect sizes for WM outcomes. Of the studies examined, 27 met the inclusion criteria. Children with TBI exhibited deficits in the CE and PL, but not in the VSSP, and no study could be found which examined the EB. Qualitative analysis found that greater TBI severity was associated with poorer CE functioning in five out of nine studies. Differences in patterns of brain activation were evident in four out of five fMRI studies that examined WM in TBI children and controls. Deficits in CE were associated with poorer mathematical skills in the only study that examined relations between WM and academic deficits. Notwithstanding the heterogeneity of the studies reviewed, TBI places children at risk of WM deficits. Moreover, this meta-analysis suggests that various components of WM have differential vulnerability to pediatric TBI, with significant deficits found in the CE and PL, but not in the VSSP (although the VSSP has rarely been examined to date). Future studies should be theoretically driven, employ tasks assessing all components of the WM model and examine the functional ramifications (including academic outcomes) of WM deficits in this population.

Abstract
Traumatic brain injury (TBI) is the greatest contributing cause of death and disability among children and young adults in the United States. The current paper briefly summarizes contemporary literature on factors that can improve outcomes (i.e., promote resilience) for children and adults following TBI. For the purpose of this paper, the authors divided these factors into static or unmodifiable factors (i.e., age, sex, intellectual abilities/education, and preinjury psychiatric history) and dynamic or modifiable factors (i.e., socioeconomic status, family functioning/social support, nutrition, and exercise). Drawing on human and animal studies, the research reviewed indicated that these various factors can improve outcomes in multiple domains of functioning (e.g., cognition, emotion regulation, health and wellness, behavior, etc.) following a TBI. However, many of these factors have not been studied across populations, have been limited to preclinical investigations, have been limited in their scope or follow-up, or have not involved a thorough evaluation of outcomes. Thus, although promising, continued research is vital in the area of factors promoting resilience following TBI in children and adults.

Abstract
The aim of the current study was to conduct a factor analysis of the Children's Memory Questionnaire-Revised (CMQ-R) and evaluate it as a reliable and effective measurement of memory functioning in children. The CMQ-R is a 36-item questionnaire designed to assess parents' perceptions of their children's memory. Three hundred and seventy-one children aged 5 to 12 years old participated in this study. Three hundred and forty-two children were recruited from schools and 29 were recruited from Kaleidoscope outpatient medical and allied health clinics. Parents of all 371 children completed the CMQ-R, and the parents of 6-, 8-, 10-, and 12-year-olds in the school group completed a 2nd CMQ-R approximately 1 month later. In the school group, children at these ages also participated in a formal assessment of memory. In the clinical group, all 29 children were tested. The results indicated that correlations between the CMQ-R and formal memory testing were low; however, these results improved slightly when age groups were separated with the highest correlation occurring for the 12-year-olds. The school and clinical groups were compared on measures of the CMQ-R, and results indicated that there was a significant difference in the CMQ-R total between the school and clinical groups. A factor analysis of the CMQ-R revealed three factors with moderate to strong loadings, and these reflected, although were not limited to, episodic memory, visual memory, and working memory/attention. The possibility is discussed that the CMQ-R was assessing different aspects of memory than formal testing and that these are likely to be everyday memory abilities.

Abstract
UNLABELLED Traumatic brain injury (TBI) is a leading cause of acquired neurologic disability in children. Erythropoietin (EPO), an anti-apoptotic cytokine, improved cognitive outcome in adult rats after TBI. To our knowledge, EPO has not been studied in a developmental TBI model. HYPOTHESIS We hypothesized that EPO would improve cognitive outcome and increase neuron fraction in the hippocampus in 17-day-old (P17) rat pups after controlled cortical impact (CCI). METHODS EPO or vehicle was given at 1, 24, and 48 h after CCI and at post injury day (PID) 7. Cognitive outcome at PID14 was assessed using Novel Object Recognition (NOR). Hippocampal EPO levels, caspase activity, and mRNA levels of the apoptosis factors Bcl2, Bax, Bcl-xL, and Bad were measured during the first 14 days after injury. Neuron fraction and caspase activation in CA1, CA3, and DG were studied at PID2. RESULTS EPO normalized recognition memory after CCI. EPO blunted the increased hippocampal caspase activity induced by CCI at PID1, but not at PID2. EPO increased neuron fraction in CA3 at PID2. Brain levels of exogenous EPO appeared low relative to endogenous. Timing of EPO administration was associated with temporal changes in hippocampal mRNA levels of EPO and pro-apoptotic factors. Conclusion/Speculation: EPO improved recognition memory, increased regional hippocampal neuron fraction, and decreased caspase activity in P17 rats after CCI. We speculate that EPO improved cognitive outcome in rat pups after CCI as a result of improved neuronal survival via inhibition of caspase-dependent apoptosis early after injury.

Abstract
OBJECTIVE Low birth weight (LBW; below 2500 grams) is a general risk factor for a variety of neurodevelopmental difficulties. However, these children may remain more vulnerable to neurologic and environmental insults occurring years later. This prospective case series reports on children who sustained a mild, moderate, or severe traumatic brain injury (TBI) in middle childhood but who had also been born with birth weights below 2500 grams. PARTICIPANTS PARTICIPANTS were 14 children with mild, moderate, or severe traumatic brain injury (TBI), 5 of whom had birth weights under 2500 grams (LBW) and 9 children with normal birth weight (NBW). All participants were drawn from a larger study on the long-term cognitive and behavioral impact of pediatric TBI and were matched on age, estimated socioeconomic status (SES), and severity of TBI (with NBW children actually having a slightly worse overall injury severity). RESULTS At baseline, both groups exhibited similar scores on WJ-R Letter Word Identification and Calculations, Tower of London number solved, and CVLT-C total correct. Baseline group differences were observed on the CELF-III Formulated Sentences (NBW > LBW) and on the VABS Adaptive Behavior Composite and Socialization subdomain (LBW > NBW). Over 2 years, relative to the NBW group, the LBW group evidenced declines on both WJ-R subtests, CVLT-C total correct, CELF-III Formulated Sentences, and VABS Adaptive Behavior Composite and Socialization. CONCLUSIONS Although preliminary in nature due to small sample size, findings suggest a history of LBW influences the recovery trajectory following childhood TBI. Academic and adaptive functioning and verbal memory appeared particularly affected.

Abstract
Children and adolescents with traumatic brain injury (TBI) often experience behavior difficulties that may arise from problem-solving deficits and impaired self-regulation. However, little is known about the relationship of neurocognitive ability to post-TBI behavioral recovery. To address this question, we examined whether verbal intelligence, as estimated by Vocabulary scores from the Wechsler Abbreviated Scale of Intelligence, predicted improvements in behavior and executive functioning following a problem-solving intervention for adolescents with TBI. One hundred and thirty-two adolescents with complicated mild-to-severe TBI were randomly assigned to a six-month Web-based problem-solving intervention (CAPS; n = 65) or to an Internet resource comparison (IRC; n = 67) group. Vocabulary moderated the association between treatment group and improvements in metacognitive abilities. Examination of the mean estimates indicated that for those with lower Vocabulary scores, pre-intervention Metacognition Index scores from the Behavior Rating Inventory of Executive Function (BRIEF) did not differ between the groups, but post-intervention scores were significantly lower (more improved) for those in the CAPS group. These findings suggest that low verbal intelligence was associated with greater improvements in executive functioning following the CAPS intervention and that verbal intelligence may have an important role in response to intervention for TBI. Understanding predictors of responsiveness to interventions allows clinicians to tailor treatments to individuals, thus improving efficacy.

Abstract
OBJECTIVE To examine cognitive predictors of academic achievement in young children with traumatic brain injury (TBI) and orthopedic injury (OI) shortly after injury and 1 year postinjury. METHODS Participants included 3- to 6-year-old children, 63 with TBI (46 with moderate TBI and 17 with severe TBI) and a comparison group of 80 children with OI. Academic achievement was assessed approximately 1 and 12 months postinjury using three subtests from the Woodcock-Johnson Tests of Achievement-Third Edition and the School Readiness Composite from the Bracken Basic Concepts Scale-Revised. General intellectual functioning, memory, and executive functions were measured at the initial assessment using standardized tests. RESULTS Hierarchical linear regression was used to predict academic achievement at the initial and 1-year follow-up assessments. Memory and executive functions were significant predictors of academic achievement at both assessments after controlling for group membership and demographic variables. Executive function remained a significant predictor of some outcomes after taking general intellectual functioning into account. Predictive relationships did not vary across the TBI and OI groups. Similar results were obtained when regression analyses were completed with only TBI participants using the Glasgow Coma Scale score as a predictor, although memory and executive functioning were somewhat less robust in predicting academic achievement than before. CONCLUSION Memory and executive function predict academic achievement after TBI in preschool children, although some of the associations may be accounted for by general intellectual functioning.

Abstract
Functional impairments (adaptive, behavioral, educational) are common after preschool traumatic brain injury (TBI). In comparison with cognitive outcome, functional outcomes have received limited attention, with little evidence to determine whether these difficulties persist in the long term. The aim of this study was to examine functional outcomes at 10 years post-injury and identify predictors of outcome. The study compared children with a diagnosis of TBI (n=40) to a healthy age-, gender-, and socioeconomic status (SES)-matched control group (n=19) at 10 years post-injury. Outcomes and predictors of functional skills were investigated. Poorer adaptive skills were evident for those with more severe injury. Behavioral difficulties were present regardless of injury severity. Post-injury, arithmetic skills were the most compromised in the longer term. Pre-injury status, interventions accessed, and acute intellectual function were significant predictors of outcome. These results highlight the importance of monitoring functional skills in the long term, especially for those children presenting with risk factors.

Abstract
The long-term consequences of child traumatic brain injury (TBI) are poorly understood, but there are indications of ongoing deterioration in skills with time since injury. This study investigated outcomes up to 10 years post-injury, to determine the influences of injury severity, injury age, and environment. The study design was prospective and longitudinal. Participants included consecutive admissions to the Royal Children's Hospital, Melbourne, Australia. Children sustaining TBI between 2 and 12 years of age (n=76) were recruited on admission and divided according to injury severity (mild, moderate, and severe) and injury age (2-7 years and 8-12 years). Cognitive abilities were evaluated using standard measures of intellectual function (IQ) acutely and at 12 months, 30 months, and 10 years post-injury. At 10 years, mean IQs for survivors fell within the low average to average range. There were no significant effects of injury severity, injury age, or time since injury. In contrast, elevated rates of impairment were identified in association with severe TBI (global deficits), and early injury (non-verbal deficits). Impairments in processing speed were related to injury severity and age at injury. Predictors of 10-year outcome included pre-injury and social factors, injury age, and family function. Child survivors of serious TBI are at elevated risk of cognitive impairment, with recovery continuing into the third year post-injury. However, between 30 months and 10 years post-insult, children appear to make appropriate developmental gains, contrary to the speculation that these children "grow into their deficits."

Abstract
Critical factors affecting traumatic brain injury (TBI) outcome in children and adolescents are explored with an emphasis on an examination of age at injury as a predictor of memory functioning. Age at injury and other injury-related and demographic predictors (i.e., severity, time postinjury, gender, and socioeconomic status [SES]) of memory and achievement outcome were examined in 65 children and adolescents post-TBI compared to 65 age-matched noninjured controls. Although robust findings have been found for age at injury as a general predictor of outcome, age was not found to be a significant predictor of memory functioning following pediatric TBI. Structural equation modeling suggests that the most parsimonious model of post-TBI outcome contains two causally related latent variables: one defined by gender, SES, injury severity, and age at injury, and one defined by general cognitive functioning.

Abstract
Childhood traumatic brain injury (TBI) is a common, acquired disability, which has significant implications for subsequent development, and for later quality of life. To date few studies have documented outcomes in these children into adolescence, when academic, social and personal demands increase. The objective of this study was to document functional outcomes at 10 years post-injury, and to identify predictors of outcome including injury, socio-demographic and pre-injury characteristics. The study employed consecutive recruitment to a prospective, longitudinal study. Children with a diagnosis of TBI between 2 and 12 years were initially recruited and divided according to injury severity (mild, moderate, severe). The sample was reviewed at 10 years post-injury and intellectual, adaptive, executive and social domains were investigated. Results indicated that, at 10 years post child TBI, survivors' functional abilities fell overall within the low average to average range regardless of injury severity, suggesting no extreme impairments at a group level for any of the domains under investigation. Significant group differences were identified, though, for adaptive abilities and for speed of processing, with more severe injury associated with poorer performances in each instance. Further, a similar trend was identified for measures of intellectual ability and executive functions. Individual rates of impairment were considerably higher than population expectations across all severity groups for these domains. Although rates of social impairment were also elevated, they were less related to injury factors, suggesting that cognitive/adaptive outcomes and social consequences of TBI may have different bases.

Abstract
Pediatric traumatic brain injury (TBI) impacts on children's executive functions, but little is known of how such deficits evolve in the long term. Forty adolescents with TBI were assessed ten years post-injury and compared to 19 typically developing participants on a range of executive measures (attentional control, cognitive flexibility, goal setting, information processing). Children with mild or moderate TBI performed within age expectations on all tests; however, those with severe injuries had poorer performance on goal setting and processing speed tasks. Childhood TBI may result in subtle lasting changes in complex executive skills, which could require ongoing support into adulthood.

Abstract
Stressful life events can result into declined memory performance at later age. One hypothesis suggests that stress affects the hippocampus, a brain area important for memory functioning. This study explored a potential relationship between the number of negative stressful life events and hippocampus-dependent declarative but not hippocampus-independent procedural memory performance in a community sample of 255 children, aged 6-12 years. The findings revealed that negative stressful life events were negatively related to verbal declarative memory, but not to nonverbal declarative and procedural memory. The memory impairments could not be accounted for by attention and sleep disturbances, and parenting characteristics as perceived by the child did not influence the vulnerability for the stress-related memory impairments. These findings provide further insight into the deleterious effects of negative stressful life events on learning in school-aged children.

Abstract
OBJECTIVE To explore the cognitive long-term outcome of two cohorts of patients neurosurgically treated for childhood traumatic brain injury (CTBI), either in 1987-1991 according to an older concept or 1997-2001 with a stronger emphasis on volume targeted interventions. RESEARCH DESIGN AND METHODS Participants in the two cohorts were subject to an extensive neuropsychological assessment, 13.2 and 6.1 years post-injury, respectively. In a between-group design, assessment results of the two cohorts, n = 18 and n = 23, were compared to each other and to controls. Data were analysed with multivariate analyses of variance. RESULTS Long-term cognitive deficits for both groups of similar magnitude and character were observed in both groups. Abilities were especially low regarding executive and memory function and verbal IQ. The cognitive results are discussed in terms of vulnerability of verbal functions and decreased executive control over memory-functions. CONCLUSIONS There is a definite need for long-term follow-up of cognitive deficits after neurosurgically treated CTBI, also with the newer neurosurgical concept. Verbal learning and the executive control over memory functions should be addressed with interventions aimed at restoration, coping and compensation.

Abstract
INTRODUCTION Traumatic brain injury (TBI) is a common, acquired disability that may be used as a model to understand the impact of early brain injury on brain structure and function. To date, few studies have followed very young children over time after insult. OBJECTIVE To plot recovery and outcome of intellectual ability after early TBI over the 5 years after injury, and to identify predictors of outcome including injury, sociodemographic and preinjury characteristics, and acute functional recovery. DESIGN Children aged between 2 and 7 years who were diagnosed with TBI (N = 54) were consecutively recruited on admission to the Royal Children's Hospital, Victoria, Australia, to participate in a prospective, longitudinal study. Our study had a between-factor design that used injury severity as the independent variable. The participants were categorized into groups according to injury severity (mild, moderate, or severe), and were compared with healthy control participants (n = 16) at the acute time point, and at 12 months, 30 months, and 5 years after injury. Intellectual measures, including verbal and nonverbal skills, attention, and processing speed, were administered. RESULTS Children with severe injuries demonstrated slower recovery and poorer cognitive outcomes up to 5 years after injury than did those who were observed for less severe injuries. Recovery trajectories were associated with injury severity over the first 30 months after injury, with the greatest deterioration in function observed for more severe injuries. From 30 months to 5 years after injury, progress was stable. Only injury severity (as determined by the Glasgow Coma Scale score) and acute cognitive performance were strong predictors of 5-year outcomes. CONCLUSIONS This study has confirmed the high risk of persisting and global deficits associated with severe brain insult in early childhood. Contrary to previous speculation about "growing into deficits," children with severe brain insults have more protracted recovery periods but do not continue to lose ground compared with their peers. By 30 months after insult, recovery seems to stabilize and children begin to make appropriate developmental gains.

Abstract
Pediatric traumatic brain injury is a major cause for concern when considering both the number of children sustaining injuries and the large number of children incurring life-long difficulties that impact on quality of life. Research is continuing to investigate outcomes and predictors of recovery in both cognitive and behavioral domains. Findings have contributed to better identification of children at high risk for neurobehavioral difficulties. The challenge is to now develop intervention programs to prevent or lessen the impact of such difficulties.

Abstract
OBJECTIVE The aims of this review were to: (i) briefly outline common sequelae following childhood traumatic brain injury (TBI); (ii) provide a summary of models and research in the area of intervention; (iii) discuss issues and obstacles in the evaluation of research in the area of intervention; (vi) discuss integrative and translational aspects of research in this area; (v) provide an example of intervention studies being conducted in the laboratory; and (vii) highlight the need for continued and collaborative work in the paediatric intervention field. CONCLUSIONS When reviewing the literature, it is clear that while challenging, the development and evaluation of intervention programs for children post traumatic brain injury, must be encourage and pursued. This in turn will lead to improved quality of life for these children and their families.
