Abstract
Youth admitted to the pediatric intensive care unit (PICU) for traumatic brain injury (TBI) commonly struggle with long-term residual effects in the domains of physical, cognitive, emotional, and psychosocial/family functioning. In the cognitive domain, executive functioning (EF) deficits are often observed. The Behavior Rating Inventory of Executive Functioning, Second Edition (BRIEF-2) is a parent/caregiver-completed measure that is regularly utilized to assess caregivers' perspectives of daily EF abilities. Using parent/caregiver-completed measures like the BRIEF-2 in isolation as outcome measures for capturing symptom presence and severity might be problematic given that caregiver ratings are vulnerable to influence from external factors. As such, this study aimed to investigate the association between the BRIEF-2 and performance-based measures of EF in youth during the acute recovery period post-PICU admission for TBI. A secondary aim was to explore associations among potential confounding factors, including family-level distress, injury severity, and the impact of pre-existing neurodevelopmental conditions. Participants included 65 youths, 8-19 years of age, admitted to the PICU for TBI, who survived hospital discharge and were referred for follow-up care. Non-significant correlations were found between BRIEF-2 outcomes and performance-based measures of EF. Measures of injury severity were strongly correlated with scores from performance-based EF measures, but not BRIEF-2. Parent/caregiver-reported measures of their own health-related quality of life were related to caregiver responses on the BRIEF-2. Results demonstrate the differences captured by performance-based versus caregiver-report measures of EF, and also highlight the importance of considering other morbidities related to PICU admission.

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
Purpose People with traumatic brain injury (TBI) often struggle with complex reading, limiting participation in work and educational settings. This systematic review and meta-analysis examined studies of reading conducted with adolescents and adults with TBI to describe reading problems post TBI and investigate underlying factors for the effects of TBI on reading abilities. Method The search was conducted in EBSCO (including MEDLINE, PsycINFO, etc.), BIOSIS, ProQuest, and Web of Science. Empirical studies that used samples with a mean age greater than 10 years, reported injury characteristics, and investigated complex reading abilities (defined as greater than single-word reading) were eligible for this review. Study quality was evaluated using QualSyst. Study and sample characteristics, measures, and outcomes of interest were extracted and synthesized in the review. Studies that compared reading abilities between people with and without TBI were included in the meta-analysis. Results Twenty-four studies met inclusion criteria, six of which addressed reading in pediatric samples. Findings from heterogeneous samples supported the existence of reading deficits post TBI, including mild TBI. In studies of children, comprehension was examined most frequently, whereas reading speed was the focus of most adult studies. Oculomotor functions and processing speed were related to reading speed; cognitive functions, such as attention and memory, were associated with reading comprehension. Intervention studies were limited, but most reported positive effects. The meta-analysis confirmed the impact of TBI on reading with a large effect size (g = 1.23). Demographic, injury, and study variables did not moderate overall reading outcomes, but male sex was a significant moderator of impairment in reading speed. Discussion Global reading ability, including both comprehension and speed, is negatively impacted by TBI. Future research should continue to explore reading after TBI, including its underlying mechanisms, effects on complex reading activities such as inferencing, development of screening and assessment tools that address a range of functional reading needs, and efficacy of reading-related interventions.

Abstract
Verbal fluency is a neuropsychological measure commonly used to examine cognitive-linguistic performance as reported in pediatric TBI literature. We synthesized the scholarly literature of verbal fluency performance in pediatric TBI and estimated the effects of TBI according to: (i) type of verbal fluency task (phonemic or semantic), (ii) severity of TBI, and (iii) time post-injury. Meta-analysis revealed that childhood TBI negatively impacted phonemic fluency and semantic fluency and that effect sizes were larger for children with more severe TBI. The negative effect of TBI was evident across time post injury within each level of severity. Verbal fluency tasks are efficient indicators of potential underlying impairments in lexical knowledge and executive functioning in children with TBI regardless of severity of injury or time post injury. Future research employing verbal fluency tasks are encouraged to explore if age at injury differentiates semantic versus phonemic fluency outcomes across severity levels.

Abstract
Purpose The purpose of this research is to determine whether individuals with a history of concussion retain enduring differences in narrative writing tasks, which necessitate rapid and complex integration of both cognitive and linguistic faculties. Method Participants aged 12-40 years old, who did or did not have a remote history of concussion, were recruited to take an online survey that included writing both a familiar and a novel narrative. They also were asked to complete multiple tasks targeting word-level and domain general cognitive skills, so that their performance could be interpreted across these dimensions. Results Participants with a concussion history were largely similar to participants with no history of brain injury across tasks that targeted a single skill in isolation. However, participants with prior concussions demonstrated difficulty in providing both key content and details when presented with a novel video and asked to provide a summary of what they had just seen. Number of lifetime concussions predicted the inclusion of key content when summarizing the video. Thus, differences in cognitive and linguistic skills required for written narrative language may continue to be present far after concussion, despite average normative levels of performance on tasks targeting these skills in isolation. Conclusions These findings suggest that individuals with a concussion history, particularly a history of multiple concussions, may continue to experience difficulties for a long period after injury and are likely to benefit from more complex and ecologically valid assessment prior to discharge. Individuals with a concussion history who return to full participation in work, school, and recreational activities may continue to benefit from assistance when asked to rapidly acquire and distill novel information, as is often required in academic and professional environments.

Abstract
OBJECTIVE To investigate the adult cognitive outcomes of one versus multiple childhood mTBI and to examine the potential predictors of the outcomes. METHODS Review of neurosurgical files and hospital records, as well as community recruitment, yielded 169 participants, who were injured between ages 0-17 years and assessed between ages 18-30 years with at least five years post-injury. Each participant underwent a three-hour assessment. For data analysis, participants were grouped by type and number of injury. RESULTS The mTBI group exhibited some cognitive deficits but their performance fell between the control and moderate/severe TBI groups as expected. Those with one and multiple mTBI performed comparably across all cognitive domains. Cognitive outcomes were significantly predicted by estimated IQ but not by number of mTBI and age at injury. CONCLUSION Despite the detected cognitive deficits, those who sustained multiple mTBI did not exhibit worse or cumulative deficits compared to those with one mTBI.

Abstract
In a prospective longitudinal study, the trajectory of verbal and visual-spatial working memory (WM) development was examined 2-, 6-, 12-, and 24-months following complicated-mild to severe pediatric traumatic brain injury (TBI; n = 55) relative to an orthopedic injury comparison group (n = 47). Individual growth curve modeling revealed an interaction of age, severity, and time for verbal, but not visual-spatial WM. The youngest children with severe TBI had the lowest scores and slowest verbal WM growth. WM outcome is best understood in light of age at injury and TBI severity. Findings support the early vulnerability hypothesis and highlight the need for long-term follow-up.

Abstract
The objectives of the study were to characterize long-term neuropsychological outcomes following traumatic brain injury (TBI) sustained during early childhood, and determine whether identified neuropsychological impairments mediated the effect of TBI on long-term adaptive functioning. Participants included 16 children with severe TBI, 42 children with moderate TBI, and 72 children with orthopedic injuries (OI) sustained between ages 3 and 7 years. Children completed neuropsychological tests and caregivers completed a structured interview of child adaptive functioning at 6.9 (±1.10) years post-injury. Profile analysis and multiple mediator modeling were employed. Children with severe TBI demonstrated poorer fluid reasoning and inhibitory control than both children with moderate TBI and OI, as well as slower processing speed than the OI group. Both fluid reasoning and processing speed were significant independent mediators of the effect of severe TBI on adaptive functioning. No neuropsychological measure significantly mediated the effect of moderate TBI on adaptive functioning. Children sustaining early severe TBI demonstrate persisting neuropsychological impairments into adolescence and young adulthood. The impact of severe TBI on children's long-term adaptive functioning is mediated in part by its effects on fluid reasoning and processing speed.

Abstract
Pediatric traumatic brain injury often results in significant long-term deficits in mastery of reading ability. This study aimed to identify white matter pathways that, when damaged, predicted reading deficits in children. Based on the dual-route model of word reading, we predicted that integrity of the inferior fronto-occipital fasciculus would be related to performance in sight word identification while integrity of the superior longitudinal fasciculus would be related to performance in phonemic decoding. Reading fluency and comprehension were hypothesized to relate to the superior longitudinal fasciculus, inferior fronto-occipital fasciculus, and cingulum bundle. The connectivity of white matter pathways was used to predict reading deficits in children aged 6 to 16 years with traumatic brain injury (n = 29) and those with orthopedic injury (n = 27) using tract-based spatial statistics. Results showed that children with traumatic brain injury and reduced microstructural integrity of the superior longitudinal fasciculus demonstrated reduced word-reading ability on sight word and phonemic decoding tasks. Additionally, children with traumatic brain injury and microstructural changes involving the cingulum bundle demonstrated reduced reading fluency. Results support the association of a dorsal pathway via the superior longitudinal fasciculus with both sight word reading and phonemic decoding. No association was identified between the inferior fronto-occipital fasciculus and sight word reading or phonemic decoding. Reading fluency was associated with the integrity of the cingulum bundle. These findings support dissociable pathways predicting word reading and fluency using Diffusion Tensor Imaging and provide additional information for developing models of acquired reading deficits by specifying areas of brain damage which may predict reading deficits following recovery from the acute phase of TBI. We apply models of white matter and reading ability to pediatric brain trauma. We report dissociable effects for integrity of specific white matter pathways and specific reading skills following injury. We report a relationship between the cingulum bundle and reading ability. The implications of these findings are discussed in terms of brain-based reading models as they relate to brain injury.

Abstract
Several neurocognitive abilities, including visual-spatial and language-based processes, attention, and fine motor/finger skills, are thought to play important roles in mathematical development and disability. Evidence for relations of specific neurocognitive skills and mathematical development and disability is presented, with a particular emphasis on findings from longitudinal studies. Why these particular neurocognitive skills are related to math is also discussed. We suggest that mathematics learning in children with congenital and acquired neurodevelopmental disorders, including children treated for cancer, is particularly vulnerable to disruption because these disorders often affect one or more of the neurocognitive systems that support math learning and performance. Implications for assessment of and interventions for math difficulties are discussed. The article ends with implications for mathematical functioning in children treated for acute lymphoblastic leukemia and brain tumors.

Abstract
OBJECTIVE Persistent post-injury cognitive, academic and behavioural deficits have been documented in children who sustained severe TBI during the school-age years. The major aim of this study was to examine and follow-up for 2 years the cognitive profile of a sample of post-injured patients (aged 6-16.11), in order to verify to what extent they recovered their intellectual functions after rehabilitation. METHOD Twenty-six patients who received a specific neuropsychological treatment and three cognitive evaluations with WISC-III were selected from a pool of 77. RESULTS This group of patients showed a mild cognitive deficit at baseline, which improved over the 2 years to a borderline level. Despite the improvement in intellectual quotients and single sub-test scores achieved through rehabilitation, different recovery times were seen according to the function under study. The most common deficits are in processing speed, inferential and lexical-semantic skills. CONCLUSIONS Detailed analysis of the WISC-III sub-tests allows for an accurate description of single cognitive functions after TBI. This allows one to make differential diagnoses between functional profiles and plan individualized rehabilitation treatments. Post-injured school-aged patients should receive rehabilitation for a period of at least 2 years, which is the time necessary for an at-least partial reorganization of basic cognitive functions.

Abstract
This study compared mathematical outcomes in children with predominantly moderate to severe traumatic brain injury (TBI; n550) or orthopedic injury (OI; n547) at 2 and 24 months post-injury. Working memory and its contribution to math outcomes at 24 months post-injury was also examined. Participants were administered an experimental cognitive addition task and standardized measures of calculation, math fluency, and applied problems; as well as experimental measures of verbal and visual-spatial working memory. Although children with TBI did not have deficits in foundational math fact retrieval, they performed more poorly than OIs on standardized measures of math. In the TBI group, performance on standardized measures was predicted by age at injury, socioeconomic status, and the duration of impaired consciousness. Children with TBI showed impairments on verbal, but not visual working memory relative to children with OI. Verbal working memory mediated group differences on math calculations and applied problems at 24 months post-injury. Children with TBI have difficulties in mathematics, but do not have deficits in math fact retrieval, a signature deficit of math disabilities. Results are discussed with reference to models of mathematical cognition and disability and the role of working memory in math learning and performance for children with TBI.

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 purpose of this study was to investigate the effects of pediatric traumatic brain injury (TBI) on verbal and visual-spatial working memory (WM). WM tasks examined memory span through recall of the last item of a series of stimuli. Additionally, both verbal and visual-spatial tests had a dual-task condition assessing the effect of increasing demands on the central executive (CE). Inhibitory control processes in verbal WM were examined through intrusion errors. The TBI group (n = 73) performed more poorly on verbal and visual-spatial WM tasks than orthopedic-injured children (n = 30) and non-injured children (n = 40). All groups performed more poorly on the dual-task conditions, reflecting an effect of increasing CE load. This effect was not greater for the TBI group. There were no group differences in intrusion errors on the verbal WM task, suggesting that problems in WM experienced by children with TBI were not primarily due to difficulties in inhibitory control. Finally, injury-related characteristics, namely days to follow commands, accounted for significant variance in WM performance, after controlling for relevant demographic variables. Findings suggest that WM impairments in TBI are general rather than modality-specific and that severity indices measured over time are better predictors of WM performance than those taken at a single time point.

Abstract
Brain insults are a risk factor for neuropsychological and academic deficits across several paediatric conditions. However, little is known about the specific effects of intracranial haemorrhage (ICH) in boys with haemophilia. The study compared neurocognitive, academic and socio-emotional/behavioural outcomes of boys with haemophilia with and without a history of ICH. Of 172 consecutive patients seen at a Pediatric Comprehensive Care Hemophila Centre, 18 had a history of ICH. Sixteen boys between the ages of 3 and 17 years were available for study and were matched to controls with haemophilia of the same age and disease severity and on the basis of maternal education. Groups were compared on neuropsychological and academic outcomes. Attention, socio-emotional function and executive skills were compared using data from parent questionnaires. Differences were found in intellectual function, visual-spatial skill, fine motor dexterity and particularly language-related skills, including vocabulary, word reading and applied math problem solving. Despite these group differences, outcomes were within the average range for most boys with ICH. No group differences were found in behavioural and socio-emotional functioning. Although ICH in haemophilia is not benign, it was not associated with significant cognitive and academic consequences for most boys. Early neuropsychological assessment may be indicated when there is a history of ICH. Investigation of age at ICH and quantitative measures of brain in relation to neurocognitive outcomes in larger groups of boys with ICH would be useful.

Social communication in young children with traumatic brain injury: relations with corpus callosum morphometry. Int J Dev Neurosci 2011; 30:247-54. [PMID: 21807088 DOI: 10.1016/j.ijdevneu.2011.07.004] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2011] [Revised: 06/17/2011] [Accepted: 07/12/2011] [Indexed: 11/22/2022] Open
Abstract
The purpose of the present investigation was to characterize the relations of specific social communication behaviors, including joint attention, gestures, and verbalization, with surface area of midsagittal corpus callosum (CC) subregions in children who sustained traumatic brain injury (TBI) before 7 years of age. Participants sustained mild (n=10) or moderate-severe (n=26) noninflicted TBI. The mean age at injury was 33.6 months; mean age at MRI was 44.4 months. The CC was divided into seven subregions. Relative to young children with mild TBI, those with moderate-severe TBI had smaller surface area of the isthmus. A semi-structured sequence of social interactions between the child and an examiner was videotaped and coded for specific social initiation and response behaviors. Social responses were similar across severity groups. Even though the complexity of their language was similar, children with moderate-severe TBI used more gestures than those with mild TBI to initiate social overtures; this may indicate a developmental lag or deficit as the use of gestural communication typically diminishes after age 2. After controlling for age at scan and for total brain volume, the correlation of social interaction response and initiation scores with the midsagittal surface area of the CC regions was examined. For the total group, responding to a social overture using joint attention was significantly and positively correlated with surface area of all regions, except the rostrum. Initiating joint attention was specifically and negatively correlated with surface area of the anterior midbody. Use of gestures to initiate a social interaction correlated significantly and positively with surface area of the anterior and posterior midbody. Social response and initiation behaviors were selectively related to regional callosal surface areas in young children with TBI. Specific brainbehavior relations indicate early regional specialization of anterior and posterior CC for social communication.

Abstract
PRIMARY OBJECTIVE The current study examined the relationship between neuropsychological performance and cognitive reserve (as measured by word reading and vocabulary tasks) in children with TBI. RESEARCH DESIGN Retrospective records analysis of the neuropsychological test results of 52 participants with medically documented traumatic brain injuries, ranging from 6-16 years of age. MAIN OUTCOME AND RESULTS Indicators of cognitive reserve were not correlated with the majority of well-recognized neuropsychological measures. CONCLUSIONS Although past research has found that verbal ability is a valid indicator of CR in adult populations, the present study found evidence against the validity of this traditional reserve proxy when applied to the paediatric population. These findings suggest one of two conclusions: (1) measures used to indicate CR in adult populations (word reading, vocabulary) are not valid indicators of cognitive reserve in paediatric populations; and/or (2) the measures themselves are valid, yet there is simply not a significant relationship between cognitive reserve and short-term (i.e. less than 6 months) neuropsychological outcome in paediatric TBI.

Abstract
BACKGROUND Traumatic brain injury (TBI) in infancy is relatively common, and is likely to lead to poorer outcomes than injuries sustained later in childhood. While the headlines have been grabbed by infant TBI caused by abuse, often known as shaken baby syndrome, the evidence base for how to support children following TBI in infancy is thin. These children are likely to benefit from ongoing assessment and intervention, because brain injuries sustained in the first year of life can influence development in different ways over many years. METHODS A literature search was conducted and drawn together into a review aimed at informing practitioners working with children who had a brain injury in infancy. As there are so few evidence-based studies specifically looking at children who have sustained a TBI in infancy, ideas are drawn from a range of studies, including different age ranges and difficulties other than traumatic brain injury. RESULTS This paper outlines the issues around measuring outcomes for children following TBI in the first year of life. An explanation of outcomes which are more likely for children following TBI in infancy is provided, in the areas of mortality; convulsions; endocrine problems; sensory and motor skills; cognitive processing; language; academic attainments; executive functions; and psychosocial difficulties. The key factors influencing these outcomes are then set out, including severity of injury; pre-morbid situation; genetics; family factors and interventions. CONCLUSIONS Practitioners need to take a long-term, developmental view when assessing, understanding and supporting children who have sustained a TBI in their first year of life. The literature suggests some interventions which may be useful in prevention, acute care and longer-term rehabilitation, and further research is needed to assess their effectiveness.

Abstract
OBJECTIVE Recovery of function after early brain injury depends upon both reparative and compensatory processes that are minimally understood. Using functional magnetic resonance imaging (fMRI), this study investigated the reorganization of hemispheric brain activity of a 24 year old male who suffered right prefrontal cortex damage at 7 years of age related to ruptured arteriovenous malformation. His pattern of recovery has been examined and tracked over the past 17 years and evolved from initial significant impairments in executive, spatial and attentional abilities from the brain lesion to remarkable recovery of function. METHODS High field fMRI studies were completed with experimental cognitive tasks sensitive to right prefrontal functions, including visuospatial relational reasoning, spatial working memory, go no-go, emotional face recognition, and coin calculation. RESULTS were compared to a matched control group for total hemispheric activity patterns. RESULTS Analyses revealed that on fMRI activation tasks where the patient scored similar to controls, he activated a broader network of bilateral cortical regions than controls. On tasks where he scored lower than controls, there was under-activation of prefrontal cortical regions in comparison to controls. CONCLUSION Recovery of function after prefrontal cortex damage in childhood can occur and be associated with significant functional reorganization of hemispheric activity patterns (i.e. developmental cerebral plasticity). Although not all tasks showed recovery to the same extent in this case, those tasks with the most robust recovery entailed compensatory activation of additional cortical regions on fMRI. Further studies are needed to confirm and extend these findings.

Abstract
This study examined the longer-term effects of traumatic brain injury (TBI) on theory of mind (ToM) skills of children who were between the ages of 5 and 7 years at the time of injury. Fifty-two children with orthopaedic injury, 30 children with moderate TBI, and 12 children with severe TBI were evaluated approximately 1 year post-injury (mean age=6.98 years, SD=0.59, range=6.02-8.26). Children with severe TBI did not engage in representation of first- and second-order mental states at a developmental level comparable to their peers, suggesting stagnation or lack of development, as well as regression of putatively existing ToM skills. Age, task-specific cognitive demands, and verbal abilities were strong predictors of ToM performance. However, even after taking those factors into account, children with severe TBI had poorer ToM performance than children with orthopaedic injuries.

Abstract
The primary aims of this study were to examine post-injury cognitive development in young children with traumatic brain injury (TBI) and to investigate the role of the proximal family environment in predicting cognitive outcomes. Age at injury was 3-6 years, and TBI was classified as severe (n = 23), moderate (n = 21), and complicated mild (n = 43). A comparison group of children who sustained orthopedic injuries (OI, n = 117) was also recruited. Child cognitive assessments were administered at a post-acute baseline evaluation and repeated at 6, 12, and 18 months post-injury. Assessment of the family environment consisted of baseline measures of learning support and stimulation in the home and of parenting characteristics observed during videotaped parent-child interactions. Relative to the OI group, children with severe TBI group had generalized cognitive deficiencies and those with less severe TBI had weaknesses in visual memory and executive function. Although deficits persisted or emerged across follow-up, more optimal family environments were associated with higher scores for all injury groups. The findings confirm other reports of poor recovery of cognitive skills following early childhood TBI and suggest environmental influences on outcomes.

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.

Abstract
Previous studies have documented weaknesses in cognitive ability and early academic readiness in young children with traumatic brain injury (TBI). However, few of these studies have rigorously controlled for demographic characteristics, examined the effects of TBI severity on a wide range of skills, or explored moderating influences of environmental factors on outcomes. To meet these objectives, each of three groups of children with TBI (20 with severe, 64 with moderate, and 15 with mild) were compared with a group of 117 children with orthopedic injuries (OI group). The children were hospitalized for their injuries between 3 and 6 years of age and were assessed an average of 1 1/2 months post injury. Analysis revealed generalized weaknesses in cognitive and school readiness skills in the severe TBI group and less pervasive effects of moderate TBI. Indices of TBI severity predicted outcomes within the TBI sample and environmental factors moderated the effects of TBI on some measures. The findings document adverse effects of TBI in early childhood on postacute cognitive and school readiness skills and indicate that these effects are related to both injury severity and the family environment.

Abstract
While a number of research papers have reported findings on memory deficits following traumatic brain injury (TBI), only limited studies have monitored the recovery of these skills over time. The present study examined memory ability and its effect on academic success in a group of children who had sustained a mild, moderate, or severe traumatic brain injury (TBI). Results showed that the severe TBI group exhibited greater deficits on memory tasks, irrespective of modality, in the acute, 6-, 12-, and 24-month postinjury stages, in comparison to mild and moderate TBI groups. Performance on academic measures was dependent on both injury severity and task demands. Preinjury academic ability and verbal memory indices best predicted academic success.

Abstract
OBJECT Although long-term neurological outcomes after traumatic brain injury (TBI) sustained early in life are generally unfavorable, the effect of TBI on the development of academic competencies is unknown. The present study characterizes intelligence quotient (IQ) and academic outcomes an average of 5.7 years after injury in children who sustained moderate to severe TBI prior to 6 years of age. METHODS Twenty-three children who suffered inflicted or noninflicted TBI between the ages of 4 and 71 months were enrolled in a prospective, longitudinal cohort study. Their mean age at injury was 21 months; their mean age at assessment was 89 months. The authors used general linear modeling approaches to compare IQ and standardized academic achievement test scores from the TBI group and a community comparison group (21 children). Children who sustained early TBI scored significantly lower than children in the comparison group on intelligence tests and in the reading, mathematical, and language domains of achievement tests. Forty-eight percent of the TBI group had IQs below the 10th percentile. During the approximately 5-year follow-up period, longitudinal IQ testing revealed continuing deficits and no recovery of function. Both IQ and academic achievement test scores were significantly related to the number of intracranial lesions and the lowest postresuscitation Glasgow Coma Scale score but not to age at the time of injury. Nearly 50% of the TBI group failed a school grade and/or required placement in self-contained special education classrooms; the odds of unfavorable academic performance were 18 times higher for the TBI group than the comparison group. CONCLUSIONS Traumatic brain injury sustained early in life has significant and persistent consequences for the development of intellectual and academic functions and deleterious effects on academic performance.

Abstract
The present study was designed: (1) to investigate the long-term consequences of both the presence and the severity of periventricular brain injury (PVBI) on intellectual, academic, and cognitive outcome in extremely-low-birthweight (ELBW: < 1,000 grams) children at a mean age of 11 years; and (2) to determine the nature of the underlying difficulties associated with academic problems in these children. The results indicated that ELBW children without PVBI performed as well as full-term children on intelligence, academic, and cognitive ability tests. In contrast, ELBW children with mild and severe PVBI achieved significantly lower scores than either ELBW children without PVBI or children who were born at term. A second analysis indicated that, after accounting for Full Scale IQ, working memory and phonological processing were significant predictors of reading and spelling performance in ELBW children. These findings suggest that the presence and severity of PVBI, and not ELBW status alone, is associated with performance on tests of intelligence, and academic and cognitive functioning, and that some of the same factors known to be associated with learning disabilities in full-term children contribute to learning disabilities in ELBW children.

Abstract
Despite traditional views, children do not necessarily recover well from brain injury. Residual functional impairments are commonly documented in physical, cognitive, educational, behavioral, and social domains and result in a significant, ongoing social and economic burden for the child's family and for the broader community. More recent acknowledgment of the serious, and often permanent, consequences of acquired brain injury in childhood has been paralleled by rapid advances in evidence-based, acute medical care and diagnostic technology. In contrast, child-based postacute rehabilitation and long-term interventions are less well developed. To date, child services have borrowed substantially from adult models, combining both direct therapies and interdisciplinary approaches. Despite their proliferation, and strong clinical support, such services are rarely the subject of rigorous evaluation and have given little acknowledgment to the important developmental factors that need to be considered when working with children. Using a developmental framework, this review aims to consider the nature of functional impairments that result from childhood traumatic brain injury, the recovery process postinjury, and the scope and role of child-based rehabilitation. In addition, the relatively scarce body of literature describing the evaluation of child rehabilitation models are reviewed with an emphasis on identifying approaches that provide evidence of enhanced function in the child's everyday life and, in particular, in the home and school contexts.

Abstract
Athletic concussion is a growing focus of attention for pediatricians. Although numerous literature reviews and clinical guidelines are now available pertaining to athletic concussion, few have focused on the pediatric athlete in particular. Sport-related concussions occur relatively frequently in children and adolescents, and primary health care providers are often responsible for coordinating clinical management. Here we summarize the scientific literature pertinent to the care of young athletes. We examine how concussion affects younger and older athletes differently at biomechanical, pathophysiological, neurobehavioral, and contextual levels. We also discuss important issues in clinical management, including preparticipation assessment, concussion evaluation and recovery tracking, and when and how to return pediatric athletes to play sports. We also briefly cover non-sport-related interventions (eg, school support). With proper management, most children and adolescents sustaining a sport-related concussion can be expected to recover fully.

Abstract
Longitudinal neuropsychological outcomes of traumatic brain injury (TBI) were investigated in 53 children with severe TBI, 56 children with moderate TBI, and 80 children with orthopedic injuries only. Neuropsychological functioning was assessed at baseline, at 6- and 12-month follow-ups, and at an extended follow-up (a mean of 4 years postinjury). Mixed model analyses revealed persistent neuropsychological sequelae of TBI that generally did not vary as a function of time postinjury. Some recovery occurred during the first year postinjury, but recovery reached a plateau after that time, and deficits were still apparent at the extended follow-up. Further recovery was uncommon after the first year postinjury. Family factors did not moderate neuropsychological outcomes, despite their demonstrated influence on behavior and academic achievement after childhood TBI.

Abstract
Recent studies of outcome after traumatic brain injury (TBI) emphasize the adverse effect of diffuse brain injury on linguistic development. This article reviews studies of lexical development, discourse processes, and reading in children and adolescents with TBI. The child's developmental level at the time of injury is related to the pattern of deficits. Young children who sustain severe TBI are particularly vulnerable to linguistic deficits at both lexical and discourse levels. TBI in older children and adolescents preferentially disrupts higher-order discourse functions. The contribution of deficits in fundamental processes, such as working memory and processing speed, to linguistic outcomes requires further investigation.

Abstract
Longitudinal behavior and achievement outcomes of traumatic brain injury (TBI) were investigated in 53 children with severe TBI, 56 children with moderate TBI, and 80 children with orthopedic injuries not involving brain insult. Measures of preinjury child and family status and of postinjury achievement skills were administered shortly after injury. Assessments were repeated 3 times across a mean follow-up interval of 4 years. Results from mixed model analysis revealed persisting sequelae of TBI. Recovery of math skills was observed in the severe TBI group but only for children from less stressed families. Social disadvantage in children with TBI predicted more adverse behavioral sequelae and less favorable changes in some outcome measures. The findings suggest that pediatric TBI has long-term effects on behavior and achievement but that postinjury progress is influenced by the family environment.

Abstract
Inferencing was studied with a story comprehension task that required inferences to be made from a controlled knowledge base. Despite similar rates of knowledge base acquisition, knowledge base retention, and speeded access to the knowledge base across groups, the 18 children with severe head injury had lower rates of inferencing than the 15 children with mild head injury or the 18 age-matched controls. Results suggest that cognitive functions such as working memory and metacognitive skill that are disrupted by severe head injury may also play a role in some of the text- and discourse-level deficits commonly reported in these children, notably those involving inferencing.

Abstract
Children with hydrocephalus decode words better than they understand what they read. We tested whether children with hydrocephalus (from myelomeningocele or aqueduct stenosis) (1) decode words slowly, (2) use decoding processes similar to those of neurologically intact peers, and (3) comprehend poorly to the extent that they are slow decoders. We compared speed of word decoding in 33 children with hydrocephalus and 33 controls matched on a pairwise basis for age, grade, and word decoding accuracy. The children with hydrocephalus were as fast as controls in reading words, but, unlike controls, they did not demonstrate an effect of spelling-sound regularity. Further, decoding speed did not contribute to reading comprehension beyond word decoding accuracy. The reading comprehension deficits of good decoders with hydrocephalus are not related to early-stage processing deficits in word recognition speed. Likely origins of comprehension failure in this group are discussed.

Abstract
Older views of the functional developmental plasticity of the developing central nervous system (CNS) focused on the protective effect of a young age at the time of insult. In these views, a younger rather than an older age at onset was thought to produce fewer and/or less severe symptoms and a more rapid recovery. More recently, neurobehavioral outcome has been studied in a variety of medical conditions that affect the developing CNS; at the same time, new investigative techniques, such as brain imaging, have elucidated the biological basis of structural and functional brain plasticity. In consequence of a better understanding of the structural and functional consequences of developmental CNS insults, a body of research has emerged that is shaping a new view of functional developmental plasticity, in which neurobehavioral outcome is set by the biological risk associated with a medical condition and moderated by age and development, the time since onset of the condition, and the reserve available within the child, family, school, and community.

Abstract
Academic success in the classroom is often dependent upon a child's ability in the areas of literacy, such as reading and spelling, and arithmetic. Following traumatic brain injury these skills are often compromised. The present study examined the recovery of educational skills (reading accuracy, reading comprehension, spelling and arithmetic) over 24 months post-injury, in a group of children who had sustained a mild, moderate or severe TBI. Results showed that the severe TBI group exhibited greater deficits on reading comprehension and arithmetic, while the moderate and severe TBI groups performed similarly in the areas of reading accuracy and spelling. Future research is required to further investigate predictors of educational outcome post-TBI.
