Abstract
Abstract: Traumatic brain injury (TBI) is a common cause of childhood morbidity and mortality. Information processing speed (IPS) is a central construct of neuropsychology and a mediator for a range of cognitive functions. In adults, the negative effects of TBI on IPS are well documented. This review qualitatively describes the impact of TBI on IPS in children and adolescents and examines various influencing factors. We included a total of 37 studies in the review that explored IPS using various clinical assessments. These clinical assessments often examine other neuropsychological functions besides IPS. In 29 of these studies, we found a negative effect of TBI on IPS. While injury severity has small but consistent effects on IPS, the effects of age at injury, time since injury, and gender were less evident. Because it is a central construct of neuropsychological functions, IPS should be assessed after TBI.

Evaluation of the PECARN rule for traumatic brain injury applied to infants younger than 3 months and creation of a modified, age-specific rule. Eur J Pediatr 2023; 182:191-200. [PMID: 36278996 DOI: 10.1007/s00431-022-04661-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Revised: 10/11/2022] [Accepted: 10/12/2022] [Indexed: 01/12/2023]
Abstract
UNLABELLED Infants < 3 months with minor head trauma (MHT) are a particularly vulnerable group, though few studies have focused specifically on these patients. We aimed to evaluate the application of the PECARN prediction rule, designed for clinically important traumatic brain injury (ciTBI) in children < 2 years in infants < 3 months, and create a specific prediction rule for this population. We conducted a prospective multicenter observational study in 13 pediatric emergency departments (PEDs) in Spain. The PECARN rule was applied to all patients. A new specific prediction rule for infants < 3 months of age was created. The main outcome measures were (1) ciTBI, (2) TBI evidenced on computed tomography (CT) scan, and (3) isolated skull fracture (ISF). Telephone follow-up was conducted for all patients over the 4 weeks after the initial PED visit. Of 21,981 children with MHT, 366 (1.7%) were < 3 months old and 195 (53.3%) underwent neuroimaging, including 37 (10.1%) with CT scan. The sensitivity and negative predictive value (NPV) of the PECARN prediction rule for ciTBI were 100% (95% CI, 20.7-100) and 99.7% (95% CI, 98.4-100%), respectively. Of the 230 infants (62.8%) who met the PECARN low-risk criteria, none had ciTBI, 1 (0.4% overall, 95% CI, 0-2.4) had TBI on CT, and 2 (0.9% overall; 95% CI, 0.1-3.1) had an ISF. Among the 136 infants (37.2%) who did not meet the PECARN low-risk criteria, 1 (0.3% overall; 95% CI, 0-1.5) had ciTBI, 11 (8.1% overall; 95% CI, 4.1-14.0) had TBI on CT, and 18 (13.2% overall; 95% CI, 8-20.1) had an ISF. The sensitivity and NPV of the Spanish prediction rule for ciTBI were 100% (95% CI, 20.7-100) and 100% (95% CI, 98.4-100%), respectively. No infants in the registry developed complications during follow-up. CONCLUSION The PECARN rule for infants < 2 years old accurately identified infants < 3 months old at low risk for ciTBI in our population, although the adapted Spanish rule presented here could be even more accurate. WHAT IS KNOWN • Infants younger than 3 months are vulnerable to minor blunt head trauma due to their age and to difficulties in assessing the subtle symptoms and minimal physical findings detected on examination. • A low threshold for CT scan is recommended in this population. WHAT IS NEW • PECARN rule for infants < 2 years old is an adequate tool with which to identify infants < 3 months old at low risk for clinically important traumatic brain injury. • Spanish rule could identify even more low-risk infants without overlooking important outcomes but it should be validated to confirm its predictive capacity.

Abstract
INTRODUCTION Paediatric acquired brain injury (ABI) causes cognitive and behavioural difficulties and alters the course of child development. The ABI unit at Hospital Infantil Universitario Niño Jesús is the first within the public Spanish health system to provide comprehensive coverage to these patients and their families. OBJECTIVE This study aims to show the working methodology followed with patients and their families, and to describe the clinical characteristics of the patients treated and the outcomes of treatment. PATIENTS Fifty-three patients aged between 3 months and 16 and a half years received treatment. The conditions treated were brain tumours, stroke, traumatic brain injury, damage secondary to epilepsy surgery, and hypoxia. METHODS All patients were evaluated at admission and at discharge. Treatments were adapted to each patient's difficulties and their severity, as well as to the patient's age. Families received individual and group therapy. RESULTS Older age was associated with better cognitive recovery and shorter duration of treatment. Different conditions show differential impact on intelligence quotient and developmental quotient scores at the beginning of treatment, with hypoxia and encephalitis being associated with greatest severity. Intelligence quotient and developmental quotient scores and visual memory and attention scores at discharge improved significantly after the faceted neuropsychological treatment with respect to scores registered at admission. CONCLUSIONS The care of patients with ABI should include neuropsychological rehabilitation programmes and provide emotional support to the family so that they may actively participate in the recovery of the child or adolescent.

Abstract
Traumatic brain injury (TBI) during critical periods of early-life brain development can affect the normal formation of brain networks responsible for a range of complex social behaviors. Because of the protracted nature of brain and behavioral development, deficits in cognitive and socioaffective behaviors may not become evident until late adolescence and early adulthood, when such skills are expected to reach maturity. In addition, multiple pre- and post-injury factors can interact with the effects of early brain insult to influence long-term outcomes. In recent years, with advancements in magnetic-resonance-based neuroimaging techniques and analysis, studies of the pediatric population have revealed a link between neurobehavioral deficits, such as social dysfunction, with white matter damage. In this review, in which we focus on contributions from Australian researchers to the field, we have highlighted pioneering longitudinal studies in pediatric TBI, in relation to social deficits specifically. We also discuss the use of advanced neuroimaging and novel behavioral assays in animal models of TBI in the immature brain. Together, this research aims to understand the relationship between injury consequences and ongoing brain development after pediatric TBI, which promises to improve prediction of the behavioral deficits that emerge in the years subsequent to early-life injury.

Abstract
This grounded theory study aims to map, conceptualize, and theorize the emotional loss experienced by parents following their child's pediatric acquired brain injury (pABI). Data were obtained from 47 semi-structured interviews conducted with parents (72% mothers) at least 1 year following pABI. The study's theory of "concurrent ropes and ladders" emerged from a process of initial in vivo coding followed by focused and thematic coding. Codes were consolidated into five thematic categories capturing parents' emotional continuous loss experience: (a) comparing life before and after, (b) struggling to construct new realities, (c) recognizing instability and permanency, (d) adjusting and readjusting, and (e) grieving as an emotional shadow. These categories are at work simultaneously in parents' accounts, thus supporting a model of dynamic concurrency within and across their lived experiences. Recommendations for practitioners were derived from the theory to support parents' emotional coping with living loss throughout the chronic stage.

Social Cognition in Paediatric Traumatic Brain Injury: A Systematic Review and Meta-analysis. Neuropsychol Rev 2021; 32:127-148.

Abstract
Recent evidence suggests social cognitive deficits may be among the most profound and disabling consequences of childhood traumatic brain injury (TBI); however, it is only over the last decade that this area has received increasing research attention. This study aims to systematically review all studies reporting on the effects of childhood TBI on social cognition. Meta-analytic techniques were employed to determine the magnitude of social cognitive deficits in childhood TBI. Literature searches were conducted in electronic databases (Medline/PubMed, Scopus, Cochrane, EMBASE, PsycINFO and CINAHL) to retrieve relevant articles on social cognitive outcomes of paediatric TBI published from 2007-2019. The systematic review identified fourteen eligible studies, which examined the effect of paediatric TBI on five dimensions of social cognition, including emotion recognition or perception, theory of Mind (ToM), pragmatic language, moral reasoning, and social problem solving. Of these studies, eleven articles were included in subsequent meta-analyses, which included 482 children with TBI. Meta-analysis using a random-effects model revealed non-significant differences between TBI and typically developing (TD) control groups on measures of emotion perception or recognition. In contrast, children and adolescents with TBI performed significantly worse than control groups on ToM and pragmatic language tasks, with small and medium effect sizes, respectively (Hedge's g = -0.46; -0.73). Meta-regression indicated that post-injury social cognitive deficits were not moderated by child age. While the effect of time since injury was not statistically significant, poorer social cognitive outcomes are documented soon after injury. Despite relatively intact basic social cognitive skills (i.e. emotion perception or recognition) children and adolescents with TBI are vulnerable to deficits in higher-order aspects of social cognition, including ToM and pragmatic language. These findings underscore the importance of further research, using well-validated, standardised outcome instruments, in larger paediatric TBI samples. Furthermore, longitudinal prospective studies are needed to evaluate the respective contribution of injury and non-injury factors to individual variation in outcome and recovery of social cognition after paediatric TBI.

Abstract
Although childhood traumatic brain injury (TBI) has been linked to heightened risk of impaired social skills and behavior, current evidence is weakened by small studies of variable methodological quality. To address these weaknesses, this international multi-cohort study involved synthesis of data from two large observational cohort studies of complicated mild-severe child TBI in Australia and North America. Both studies adopted a unified approach to data collection and coding procedures, providing the opportunity to merge datasets from multiple, well-characterized cohorts for which gold standard measures of social outcomes were collected during the chronic recovery phase. The study involved 218 children, including 33 children with severe TBI, 83 children with complicated mild-moderate TBI, 59 children with orthopedic injury, and 43 age- and sex-matched typically developing control children. All injured children were recruited from academic children's hospitals and underwent direct cognitive assessments including measures of theory of mind (ToM) at least 1-year post- injury. Parents rated their child's social adjustment using standardized measures of social skills, communication and behavior. Results showed a brain-injury specific effect on ToM abilities, such that children with both complicated mild to moderate and severe TBI displayed significantly poorer ToM than children without TBI. In mediator models, poorer ToM predicted poorer parent-rated self-direction and social skills, as well as more frequent behavioral symptoms. The ToM mediated the effect of severe TBI on parent ratings of communication and social skills, as well as on overall behavior symptoms. The findings suggest that deficits in ToM are evident across the spectrum of TBI severity and represent one mechanism linking severe child TBI to long-term social adjustment difficulties. The findings underscore the value of large-scale data harmonization projects to increase the quality of evidence regarding the outcomes of TBI. Clinical and scientific implications are discussed.

Abstract
OBJECTIVES To describe the immunotherapy and pharmacologic treatments administered to pediatric patients with N-methyl-D-aspartate receptor encephalitis (NMDARE) during inpatient rehabilitation as well as to examine clinical and demographic variables associated with early functional outcomes. DESIGN Retrospective chart review and post hoc analysis. SETTING Pediatric inpatient rehabilitation unit. PARTICIPANTS Pediatric patients (N=26; mean age, 10.79±5.17y) admitted to an inpatient rehabilitation unit with a confirmed diagnosis of NMDARE. INTERVENTIONS Inpatient rehabilitation; pharmacologic treatments. MAIN OUTCOME MEASURE FIM for Children (WeeFIM) Developmental Functional Quotient (DFQ). RESULTS All patients received first-line immunotherapies to treat NMDARE, and 69% also received second-line immunotherapies. Patients were prescribed an average of 8 medications for symptom management (range, 3-15 per patient), most often for the treatment of agitation (100%), psychiatric symptoms (92%), and seizures (65%). Sixty-five percent of patients demonstrated an improvement in Total WeeFIM DFQ over the course of inpatient rehabilitation, with 35% demonstrating limited to no change in Total WeeFIM DFQ ("unfavorable early outcome"). Those with unfavorable early outcome were significantly younger than those showing more favorable outcome. Pharmacologic treatment for seizures, movement disorders, and decreased arousal or level of consciousness were each associated with unfavorable early outcome independent of age differences. CONCLUSION Findings highlight the symptomatic heterogeneity and polypharmacy involved in the care and treatment of patients with NMDARE, with patients receiving a variety of immunotherapies and medications for symptom management. The presence of (and treatment for) seizures, movement disorders, and deteriorated neurologic status may each be associated with poor early outcomes in this population. Further investigation is needed to better classify presentations and treatments for this disease and to determine how differences are associated with long-term outcomes.

Abstract
OBJECTIVE Traumatic brain injuries (TBIs) often adversely affect adaptive functioning (AF). However, the cognitive mechanisms by which AF is disrupted are not well understood in young children who sustain TBI. This study examined pragmatic language (PL) and executive functioning (EF) as potential mechanisms for AF disruption in children with early, predominantly mild-complicated, TBI. METHOD The sample consisted of 76 children between the ages of 6 and 10 years old who sustained a TBI (n = 36) or orthopedic injury (OI; n = 40) before 6 years of age and at least 1 year prior to testing (M = 4.86 years, SD = 1.59). Children's performance on a PL and an expressive vocabulary task (which served as a control task), and parent report of child's EF and AF were examined at two time points 1 year apart (i.e., at age 8 and at age 9 years). RESULTS Injury type (TBI vs. OI) significantly predicted child's social and conceptual, but not practical, AF. Results indicated that PL, and not expressive vocabulary or EF at time 1, mediated the relationship between injury type and both social and conceptual AF at time 2. CONCLUSIONS A TBI during early childhood appears to subtly, but uniquely, disrupt complex language skills (i.e., PL), which in turn may disrupt subsequent social and conceptual AF in middle childhood. Additional longitudinal research that examines different aspects of PL and adaptive outcomes into adolescence is warranted.

Abstract
Neurodegenerative disease is an umbrella term for different conditions which primarily affect the neurons in the human brain. In the last century, significant research has been focused on mechanisms and risk factors relevant to the multifaceted etiopathogenesis of neurodegenerative diseases. Currently, neurodegenerative diseases are incurable, and the treatments available only control the symptoms or delay the progression of the disease. This review is aimed at characterizing the complex network of molecular mechanisms underpinning acute and chronic neurodegeneration, focusing on the disturbance in redox homeostasis, as a common mechanism behind five pivotal risk factors: aging, oxidative stress, inflammation, glycation, and vascular injury. Considering the complex multifactorial nature of neurodegenerative diseases, a preventive strategy able to simultaneously target multiple risk factors and disease mechanisms at an early stage is most likely to be effective to slow/halt the progression of neurodegenerative diseases.

Abstract
Traumatic brain injury (TBI) can affect individuals at any age, with the potential of causing lasting neurologic consequences. The lack of effective therapeutic solutions and recommendations for patients that acquire a TBI can be attributed, at least in part, to an inability to confidently predict long-term outcomes following TBI, and how the response of the brain differs across the life span. The purpose of this study was to determine how age specifically affects TBI outcomes in a preclinical model. Male Thy1-YFPH mice, that express yellow fluorescent protein in the cytosol of a subset of Layer V pyramidal neurons in the neocortex, were subjected to a lateral fluid percussion injury over the right parietal cortex at distinct time points throughout the life span (1.5, 3, and 12 months of age). We found that the degree of neuronal injury, astrogliosis, and microglial activation differed depending on the age of the animal when the injury occurred. Furthermore, age affected the initial injury response and how it resolved over time. Using the microtubule stabilizing agent Epothilone D, to potentially protect against these pathologic outcomes, we found that the neuronal response was different depending on age. This study clearly shows that age must be taken into account in neurologic studies and preclinical trials involving TBI, and that future therapeutic interventions must be tailored to age.

Joint Neuropsychological Assessment through Coma/Near Coma and Level of Cognitive Functioning Assessment Scales Reduces Negative Findings in Pediatric Disorders of Consciousness. Brain Sci 2020; 10:E162. [PMID: 32178348 PMCID: PMC7140001 DOI: 10.3390/brainsci10030162] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2020] [Revised: 02/28/2020] [Accepted: 03/10/2020] [Indexed: 01/26/2023] Open
Abstract
The present study aimed to: (a) characterize the emergence to a conscious state (CS) in a sample of children and adolescents with severe brain injury during the post-acute rehabilitation and through two different neuropsychological assessment tools: the Rappaport Coma/Near Coma Scale (CNCS) and Level of Cognitive Functioning Assessment Scale (LOCFAS); (b) compare the evolution in patients with brain lesions due to traumatic and non-traumatic etiologies; and (c) describe the relationship between the emergence to a CS and some relevant clinical variables. In this observational prospective longitudinal study, 92 consecutive patients were recruited. Inclusion criteria were severe disorders of consciousness (DOC), Glasgow Coma Scale (GCS) score ≤8 at insult, age 0 to 18 years, and direct admission to inpatient rehabilitation from acute care. The main outcome measures were CNCS and LOCFAS, both administered three and six months after injury. The cohort globally shifted towards milder DOC over time, moving from overall 'moderate/near coma' at three months to 'near/no coma' at six months post-injury. The shift was captured by both CNCS and LOCFAS. CNCS differentiated levels of coma at best, while LOCFAS was superior in characterizing the emergence from coma. Agreement between scales was fair, and reduced negative findings at less than 10%. Patients with traumatic brain injury (TBI) vs. non-traumatic brain injury (NTBI) were older and had neurosurgical intervention more frequently. No relation between age and the level of consciousness was found overall. Concurrent administration of CNCS and LOCFAS reduced the rate of false negatives and better detected signs of arousal and awareness. This provides indication to administer both tools to increase measurement precision.

Abstract
OBJECTIVE Traumatic brain injury due to road traffic accidents occurs mainly in the younger age group in which injury-related disability leads to long-term impact on employment and economic and social consequences across the lifespan. This study was designed to assign a monetary cost (in Malaysian ringgits [RM]) to the treatment of patients with surgically treated isolated traumatic head injury as determined up to 1 year after injury. METHODS Relevant resource items used were identified and valued using the direct measurement of costs method, cost accounting methods, standard unit costs method, fees, charges and/or market prices method. These values were then tabulated to generate the total costs for each patient, via a combination of macro-costing and micro-costing methods. Malaysian currency values were converted to US dollars according to the average conversion rate for the period from January to May 2016: RM1 = US$0.2452. RESULTS This costing study analyzed data from 49 patients. The estimated cost for the 1st year of care for all patients was RM1,471,919.80 (US$360,914.735), with a mean (± SD) cost per case of RM30,039.18 ± 22,986.25 or $7365.61 ± $5636.23. The mean cost of care per case was RM11,041.35 ± 10,936.88 or $2707.34 ± $2681.72 for mild head injury, RM32,550.00 ± 20,998.76 or $7981.26 ± $5148.90 for moderate head injury, and RM36,917.86 ± 23,697.34 or $9052.26 ± $5810.59 for severe head injury. Severe head injury (p = 0.001), sustaining 2 or more intracranial pathologies (p = 0.01), having a poor Glasgow Outcome Scale (GOS) score (GOS score 1-3) (p = 0.02), requiring a tracheostomy (p < 0.001), and contracting pneumonia (p < 0.001) were significantly associated with higher cost. Logistic regression analysis revealed that cost of care increased by RM591.60 or $145.06 per year increment of age (β = RM591.60, p = 0.05). CONCLUSIONS The mean cost of treatment for traumatic head injury is high compared to the per capita income of RM37,900 in 2016. The cost values generated in this study provide baseline cost estimates that the authors hope will be used as a guide to determine where adequate funding should be allocated to provide timely and appropriate delivery of care.

Abstract
Traumatic brain injuries in children represent a major public health issue and even relatively mild injuries can have lifelong consequences. However, the outcomes from these injuries are highly heterogeneous, with most individuals recovering fully, but a substantial subset experiencing prolonged or permanent disabilities across a number of domains. Moreover, brain injuries predispose individuals to other kinds of neuropsychiatric and somatic illnesses. Critically, the severity of the injury only partially predicts subsequent outcomes, thus other factors must be involved. In this review, we discuss the psychological, social, neuroendocrine, and autonomic processes that are disrupted following traumatic brain injury during development, and consider the mechanisms the mediate risk or resilience after traumatic brain injury in this vulnerable population.

Abstract
OBJECTIVE Traumatic brain injury is now a major contributor to the global healthcare burden. Migraine is another debilitating disease with a global health impact. While most researchers agree that traumatic brain injury is a risk factor for migraine, whether migraine is a risk factor for traumatic brain injury still remains under debate. We therefore aimed to investigate whether migraine was a risk factor for developing traumatic brain injury. STUDY DESIGN Retrospective population-based cohort study. SETTING Data for people who had been diagnosed with migraine were retrieved from Taiwan's National Health Insurance Research Database. PARTICIPANTS We identified 7267 patients with newly diagnosed migraine during 1996-2010. The migraineurs to non-migraineurs ratio was set at 1:4 to enhance the power of statistical tests. PRIMARY AND SECONDARY OUTCOME MEASURES We used multivariate Cox proportional hazard regression models to assess the effects of migraines on the risk of traumatic brain injury after adjusting for potential confounders. RESULTS The overall traumatic brain injury risk was 1.78 times greater in the migraine group compared with the non-migraine group after controlling for covariates. Additionally, patients with previous diagnoses of alcohol-attributed disease, mental disorders and diabetes mellitus had a significantly higher traumatic brain injury risk compared with those with no history of these diagnoses. CONCLUSIONS This study of a population-based database indicated that migraine is a traumatic brain injury risk factor. Greater attention to migraine-targeted treatment modalities may reduce traumatic brain injury-related morbidity and mortality.

Abstract
PRIMARY OBJECTIVE To investigated the long-term effect of childhood Traumatic Brain Injury (TBI) on adulthood Relationship Quality (RQ), examining injury severity, age of injury, and markers of prefrontal cortex (PFC) functioning, apathy, disinhibition, and executive dysfunction. RESEARCH DESIGN Longitudinal, between-subjects, cross-sectional design using retrospective and current data. METHODS AND PROCEDURES Participants (N = 169; 61 mild TBI (mTBI); 65 moderate to severe TBI (MSTBI); 43 orthopaedic injury (OI); Injury age: 1-17 years; Testing age: 18-31 years) completed a structured interview regarding their injury, demographic characteristics and RQ, the National Adults Reading Test, and Frontal Systems Behaviour Scale. Data were analyzed using IBM SPSS 25. MAIN OUTCOMES AND RESULTS Adults who had experienced childhood TBI had significantly poorer RQ than adults who had experienced childhood OI. Severity of TBI did not impact adulthood RQ. Earlier age of injury predicted reduced adulthood RQ in the MSTBI group. Greater PFC dysfunction predicted poorer RQ in adults with a history of childhood TBI. While elevated levels of apathy, disinhibition, and executive dysfunction were associated with poorer RQ, no individual marker had predictive value. CONCLUSION Experiencing a childhood TBI can have a long-term negative influence on adulthood RQ. Such RQ deficits can underpin reduced life satisfaction and increased health issues.

Abstract
Traumatic brain injury (TBI) during early childhood is associated with a particularly high risk of developing social behavior impairments, including deficits in social cognition that manifest as reduced social interactions, with profound consequences for the individuals' quality of life. A number of pre-injury, post-injury, and injury-related factors have been identified or hypothesized to determine the extent of social behavior problems after childhood TBI. These include variables associated with the individual themselves (e.g. age, genetics, the injury severity, and extent of white matter damage), proximal environmental factors (e.g. family functioning, parental mental health), and more distal environmental factors (e.g. socioeconomic status, access to resources). In this review, we synthesize the available evidence demonstrating which of these determinants influence risk versus resilience to social behavior deficits after pediatric TBI, drawing upon the available clinical and preclinical literature. Injury-related pathology in neuroanatomical regions associated with social cognition and behaviors will also be described, with a focus on findings from magnetic resonance imaging and diffusion tensor imaging. Finally, study limitations and suggested future directions are highlighted. In summary, while no single variable can alone accurately predict the manifestation of social behavior problems after TBI during early childhood, an increased understanding of how both injury and environmental factors can influence social outcomes provides a useful framework for the development of more effective rehabilitation strategies aiming to optimize recovery for young brain-injured patients.

Abstract
A range of functions can be negatively affected by pre-frontal cortex (PFC) injury, but observed behavioural and social changes are commonly linked to post-injury changes in executive function. Executive functioning is a complex neuropsychological construct which is further complicated by neuro-developmental processes when applied to children. There is a substantial and continuing evidence base that supports the view that early childhood pre-frontal cortex (PFC) injury results in hidden, dormant, or sleeping effects. In contrast, recent and rapidly accruing contemporary studies provide preliminary evidence that challenge the view that PFC associated impairments are completely 'hidden'. Studies that examine the various functions of the PFC and differentiate these to provide preliminary evidence to indicate earlier EF development than that which develops upon reaching adolescence, are reviewed here, together with research that identifies early predictors of later EF impairments. It remains that studies of PFC function and/or structural brain-changes are substantially complicated by issues related to definition regarding functions of the PFC, measurement of EF and other PFC-related functions that may be better understood as meta-processes. These issues are discussed in the concluding sections of this paper.

Abstract
Traumatic brain injury (TBI) is a major public health problem associated with high morbidity and mortality rates in children in both high- and low- and middle-income countries. Predicting outcome after pediatric TBI is challenging given the wide range of injury and non-injury-related factors which may have an impact. Some of these factors are relevant globally (like heterogeneity in patient and injury-related factors and research methodology) and others are more specific to local contexts (like sociodemographic and cultural factors). The assessment of rehabilitation outcomes post-TBI are similarly challenging given the various methodological limitations, disparities in access to rehabilitation, and limited awareness of deficits, which are encountered globally, as well as the lack of services in the local settings. In this article, we discuss these global and local challenges to outcome and rehabilitation assessment following pediatric TBI.

Abstract
This study compared neurologic disability and adaptive function in children and adults >1 year following anti- N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis diagnosis. Retrospective record review identified 12 patients with anti-NMDAR encephalitis. At last follow-up, all surviving patients had "good" modified Rankin Score (0-2). Four children, 6 adults, and their families participated in a telephone interview. Median duration since diagnosis was similar for children (2.42 years, interquartile range 2.12-3.32) and adults (3.55 years, interquartile range 2.08-5.50 years). 3/4 (75%) pediatric and 3/5 (60%) adult patients reported neuropsychiatric symptoms (fatigue, emotional lability, short-term memory deficits or concentration deficits). On the Adaptive Behavior Assessment System (ABAS-3), although overall adaptive function was intact for adults (general adaptive composite standard score: median 104.5, interquartile range 98.8-112.5), the median for children was below average (General Adaptive Composite Standard Score: median 82.0, interquartile range 79.0-89.0). Children with anti-NDMAR encephalitis may have long-term effects impacting daily life while adults regain normal function.

PM R 2017; 9:874-883. [PMID: 28082178 PMCID: PMC5502002 DOI: 10.1016/j.pmrj.2016.12.005] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2016] [Revised: 12/16/2016] [Accepted: 12/23/2016] [Indexed: 11/25/2022]
Abstract
BACKGROUND Current concussion evidence is derived largely from teenagers and adults. Concussion in younger children occurs within the context of neuromaturation, with differing age-based pathophysiological responses to injury. Therefore, our current understanding of concussion in older children and adults is unlikely to directly apply to younger children. OBJECTIVE To describe patient variables, clinical course, and factors associated with time to discharge from concussion care in children 6-12 years of age with concussion treated in an interdisciplinary rehabilitation-based concussion clinic. DESIGN Retrospective chart review. SETTING Interdisciplinary concussion clinic at an academically affiliated rehabilitation center. PATIENTS Children aged 6-12 years (n = 105; mean 10.8 years of age, 70% male) seen within 60 days of concussive injury. MAIN OUTCOME MEASUREMENTS Descriptive statistics explored demographic, injury, and clinical features. The primary outcome measure, time to discharge from concussion care, was estimated with survival-analysis methods based on the date of discharge from the clinic. Multivariate models were used to examine factors associated with longer time to discharge. RESULTS Median time to discharge was 34 days postinjury (range 5-192 days); 75% of children were discharged within 60 days of injury. A minority reported persisting symptoms at discharge. Younger age and increased symptom burden at initial evaluation predicted longer time to discharge. CONCLUSIONS Although children 6-12 years old treated in a specialty concussion clinic show variability in time to discharge from concussion care, most were discharged within 2 months after injury. Risk factors for prolonged recovery, such as younger age and greater symptom burden at initial visit, can be used when counseling families and planning interventions. There may be varying contributions, including psychosocial stressors, to ongoing symptoms in children who experience persisting symptoms after other concussion-related concerns have resolved. Future work focused on the subset of children who report persisting symptoms will be useful for developing an evidence base related to their care. LEVEL OF EVIDENCE II.

Abstract
Youth with perinatal HIV infection (PHIV) are at increased risk for neurocognitive impairment (NCI). Prospective memory (PM) is a complex neurocognitive function that has been shown to be impaired in adults with HIV disease and independently associated with poorer daily living skills, including medication nonadherence. The current study sought to determine the presence and extent of PM deficits in youth with PHIV. Participants included 173 youth with PHIV and 85 youth perinatally HIV-exposed but uninfected (PHEU), mean age 14.1 years, 75% black, 18% Hispanic. Among youth with PHIV, 26% had a past AIDS-defining condition (Centers for Disease Control and Prevention [CDC], Class C), 74% did not (non-C). Adjusted generalized estimating equation models were used to compare groups (PHIV/C, PHIV/non-C, and PHEU) on the Naturalistic Event-Based Prospective Memory Test (NEPT) and the Prospective Memory Assessment for Children & Youth (PROMACY). Secondarily, subgroups defined by HIV serostatus and global NCI were compared (PHIV/NCI, PHIV/non-NCI, PHEU). PHIV/C had significantly lower NEPT scores than PHEU, with decreases of 40% in mean scores, but did not differ from PHIV/non-C. PHIV/NCI had 11-32% lower PROMACY scores and 33% lower NEPT scores compared to PHIV/non-NCI (all p < .05); significantly, lower scores for PHIV/NCI versus PHEU also were observed for PROMACY and NEPT indices. Findings suggest a subset of youth with PHIV (those with a prior AIDS-defining diagnosis) is vulnerable to PM deficits. The extent to which PM deficits interfere with development and maintenance of independent living and health-related behaviors during transition to adulthood requires further study.

Abstract
INTRODUCTION The association between age at injury (AAI) and long-term cognitive outcome of traumatic brain injuries (TBI) is debatable. METHODS Eligible participants with a history of TBI from Alzheimer's Disease Neuroimaging Initiative were divided into a childhood TBI (cTBI) group (the AAI ≤ 21 years old) and an adult TBI (aTBI) group (the AAI > 21 years old). RESULTS The cTBI group has a higher Everyday Cognition total score than the aTBI group. All perceived cognitive functions are worse for the cTBI group than for the aTBI group except memory. By contrast, the cTBI group has higher assessment scores on either the Boston Naming Test or Rey Auditory Verbal Learning Test than the aTBI group. DISCUSSION The AAI is associated with the long-term cognitive outcomes in older adults with a history of TBI.

Abstract
BACKGROUND Executive function (EF) impairment is a major predictor of overall outcome after traumatic brain injury (TBI). TBI severity is a factor of poor outcome, but most studies include a majority of children with mild and moderate TBI. The aims of this study were to estimate EF impairment after severe childhood TBI and to explore factors predicting EF outcome. The secondary aim was to compare recovery trajectories by age-at-injury groups. METHODS This was a prospective longitudinal study of children with severe TBI who were tested for EFs by performance-based tests and questionnaires at 3, 12 and 24 months. RESULTS Children with TBI (n=65) showed significant impairment in working memory, inhibition, attention and global EF, with little or no recovery at 24 months. For flexibility and performance-based EF score, children were impaired at 3 months only and showed normal scores by 12 months. No impairment was found in planning. At 3 and 24 months, Glasgow Coma Scale score and parental education predicted global EF. Coma length was not a significant predictor of outcome. Age at injury predicted progress in EF, but the relationship was not linear; children 10-12 years old at injury showed better outcome than older and younger children. CONCLUSIONS EFs are impaired after severe TBI in childhood. The relationship between age at injury and outcome is not linear. Relying on only performance-based EF tests can underestimate EF impairment.

Abstract
Development and aging are influenced by external factors with the potential to impact health throughout the life span. Traumatic brain injury (TBI) can initiate and sustain a lifetime of physical and mental health symptoms. Over 1.7 million TBIs occur annually in the USA alone, with epidemiology suggesting a higher incidence for young age groups. Additionally, increasing life spans mean more years to age with TBI. While there is ongoing research of experimental pediatric and adult TBI, few studies to date have incorporated animal models of pediatric, adolescent, and adult TBI to understand the role of age at injury across the life span. Here, we explore repeated behavioral performance between rats exposed to diffuse TBI at five different ages. Our aim was to follow neurological morbidities across the rodent life span with respect to age at injury. A single cohort of male Sprague-Dawley rats (n = 69) was received at postnatal day (PND) 10. Subgroups of this cohort (n = 11-12/group) were subjected to a single moderate midline fluid percussion injury at age PND 17, PND 35, 2 months, 4 months, or 6 months. A control group of naïve rats (n = 12) was assembled from this cohort. The entire cohort was assessed for motor function by beam walk at 1.5, 3, 5, and 7 months of age. Anxiety-like behavior was assessed with the open field test at 8 months of age. Cognitive performance was assessed using the novel object location task at 8, 9, and 10 months of age. Depression-like behavior was assessed using the forced swim test at 10 months of age. Age at injury and time since injury differentially influenced motor, cognitive, and affective behavioral outcomes. Motor and cognitive deficits occurred in rats injured at earlier developmental time points, but not in rats injured in adulthood. In contrast, rats injured during adulthood showed increased anxiety-like behavior compared to uninjured control rats. A single diffuse TBI did not result in chronic depression-like behaviors or changes in body weight among any groups. The interplay of age at injury and aging with an injury are translationally important factors that influence behavioral performance as a quality of life metric. More complete understanding of these factors can direct rehabilitative efforts and personalized medicine for TBI survivors.

Abstract
INTRODUCTION While the presence of externalizing behavioral problems following traumatic brain injury (TBI) has been well established in the literature, less is known regarding internalizing disorders, and more specifically anxiety disorders, in such a population. This study explored the presence, rate, and incidence of internalizing behavior problems, including anxiety, depression, somatic complaints, avoidant personality symptomatology, and overall internalizing behavior problems in university students aged 18-25 years. METHOD A convenience sample of 247 university students (197 non-TBI, 47 mild TBI, 2 moderate TBI, 1 severe TBI) aged 18-25 years was utilized. Participants completed a self-report measure on behavioral functioning, the Adult Self Report (ASR), to identify internalizing behaviors, and a questionnaire to identify TBI history. RESULTS Raw scores of behavior indicated that participants with a history of childhood TBI reported significantly higher levels of withdrawal, somatic complaints, and internalizing behavioral problems than the non-TBI participants. When analyzing standardized T-scores for borderline and clinically elevated ASR syndromes and Diagnostic and Statistical Manual of Mental Disorders (DSM)-oriented scales, individuals in the TBI group were significantly more likely to have higher rates of borderline anxiety, somatic complaints, avoidant personality problems, and overall internalizing disorders, and clinically elevated somatic complaints. Adults with a history of childhood TBI were also significantly more likely to report at least 1 or more DSM disorders. CONCLUSION These results clearly suggest that individuals with a childhood history of TBI are at a heightened risk for a range of internalizing disorders in early adulthood, which is particularly troubling in a university sample pursuing tertiary education.

Abstract
OBJECTIVE To determine health-related quality of life (HRQoL) in children and youth with acquired brain injury (ABI) two years post-injury and explore associated factors. DESIGN Cross-sectional. SUBJECTS Children and youth (n = 72; aged 6-22 years) with mild to severe ABI (87% mild). METHODS The primary outcome measures self-reported and parent-reported HRQoL were assessed with the Paediatric Quality of Life Inventory (PedsQL) and compared with age-appropriate reference values of the Dutch population. Spearman correlation coefficients (Rs) were used to explore relationships between HRQoL and sociodemographic and ABI characteristics, severity of impairments and presence of post-injury problems. RESULTS Children and youth with ABI and the reference population had similar self-reported HRQoL. However, as reported by parents, children with ABI aged 6-7 years and youth aged 13-18 years had poorer HRQoL regarding psychosocial health. Children's post-injury cognitive, behavioural and social problems were moderately associated with poorer HRQoL, especially psychosocial health (Rs ≥ 0.40). Severity nor type of injury were associated with children's HRQoL. CONCLUSION Two years post-injury, in children and youth with mild to severe ABI, reported HRQoL is similar to that in the general population, whereas parents reported less favourable outcomes. Post-injury cognitive, behavioural and social problems require ongoing attention during long-term follow-up.

Abstract
Sleep is often disrupted in traumatic brain injury (TBI) and may be related to persistent behaviour problems; however, little is known about this relationship in young adults. This study explored associations between TBI, behavioural problems and sleep disturbances in 247 university students (197 non-TBI, 47 mild TBI, two moderate TBI, one severe TBI) aged 18-25 years, who completed validated measures for behaviour, sleep quality and history of TBI. Because of small group numbers, participants reporting moderate to severe TBI were excluded from the analyses. Results indicated that students with mild TBI reported higher levels of daytime dysfunction, somatic complaints, withdrawal, other behavioural complaints and internalizing behaviours compared with students with no TBI history. A correlational analysis indicated a moderate relationship between the above significant variables. Our results suggest that university students with a history of mild TBI are more likely to experience certain ongoing daytime behavioural problems, which are likely to negatively influence their academic functioning in tertiary education. This study highlights the importance of research on long-term problems following mild TBI in young adults aged 18-25 years--an age group often overlooked within the literature.

Abstract
The aim of this review is to discuss in greater detail the topics covered in the recent symposium entitled "Traumatic brain injury: laboratory and clinical perspectives," presented at the 2014 International Behavioral Neuroscience Society annual meeting. Herein, we review contemporary laboratory models of traumatic brain injury (TBI) including common assays for sensorimotor and cognitive behavior. New modalities to evaluate social behavior after injury to the developing brain, as well as the attentional set-shifting test (AST) as a measure of executive function in TBI, will be highlighted. Environmental enrichment (EE) will be discussed as a preclinical model of neurorehabilitation, and finally, an evidence-based approach to sports-related concussion will be considered. The review consists predominantly of published data, but some discussion of ongoing or future directions is provided.

Abstract
Worldwide, 54-60 million individuals sustain traumatic brain injury (TBI) each year. This meta-analysis aimed to quantify intelligence impairments after TBI and to determine the value of age and injury severity in the prognosis of TBI. An electronic database search identified 81 relevant peer-reviewed articles encompassing 3890 patients. Full-scale IQ (FSIQ), performance IQ (PIQ) and verbal IQ (VIQ) impairments were quantified (Cohen's d) for patients with mild, moderate and severe TBI in the subacute phase of recovery and the chronic phase. Meta-regressions explored prognostic values of age and injury severity measures for intelligence impairments. The results showed that, in the subacute phase, FSIQ impairments were absent for patients with mild TBI, medium-sized for patients with moderate TBI (d = -0.61, P < 0.001) and large for patients with severe TBI (d = -1.09, P < 0.001). In the chronic phase, FSIQ impairments were small for patients with mild or moderate TBI (d = -0.37 and -0.19, P ≤ 0.008) and large for patients with severe TBI (d = -0.80, P < 0.001). Adults with mild TBI had larger PIQ and VIQ impairments in the chronic phase than children (both Q ≥ 5.21, P ≤ 0.02), whilst children with severe TBI had larger FSIQ and VIQ impairments than adults (both Q ≥ 4.40, P ≤ 0.04). Glasgow Coma Scale score, duration of loss of consciousness and post-traumatic amnesia duration moderately to strongly predicted FSIQ, PIQ and VIQ impairments (0.41 ≤ r ≤ 0.82, P ≤ 0.02), but no differences in predictive value were observed. In conclusion, TBI causes persisting intelligence impairments, where children may have better recovery from mild TBI and poorer recovery from severe TBI than adults. Injury severity measures predict intelligence impairments and do not outperform one another.

Predictors of longitudinal outcome and recovery of pragmatic language and its relation to externalizing behaviour after pediatric traumatic brain injury. BRAIN AND LANGUAGE 2015; 142:86-95. [PMID: 25677376 DOI: 10.1016/j.bandl.2015.01.007] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2014] [Revised: 01/04/2015] [Accepted: 01/05/2015] [Indexed: 06/04/2023]
Abstract
The purpose of the present investigation was to evaluate the contribution of age-at-insult and brain pathology on longitudinal outcome and recovery of pragmatic language in a sample of children and adolescents with traumatic brain injury (TBI). Children and adolescents with mild to severe TBI (n=112) were categorized according to timing of brain insult: (i) Middle Childhood (5-9 years; n=41); (ii) Late Childhood (10-11 years; n=39); and (iii) Adolescence (12-15 years; n=32) and group-matched for age, gender and socio-economic status (SES) to a typically developing (TD) control group (n=43). Participants underwent magnetic resonance imaging (MRI) including a susceptibility weighted imaging (SWI) sequence 2-8 weeks after injury and were assessed on measures of pragmatic language and behavioural functioning at 6- and 24-months after injury. Children and adolescents with TBI of all severity levels demonstrated impairments in these domains at 6-months injury before returning to age-expected levels at 2-years post-TBI. However, while adolescent TBI was associated with post-acute disruption to skills that preceded recovery to age-expected levels by 2-years post injury, the middle childhood TBI group demonstrated impairments at 6-months post-injury that were maintained at 2-year follow up. Reduced pragmatic communication was associated with frontal, temporal and corpus callosum lesions, as well as more frequent externalizing behaviour at 24-months post injury. Findings show that persisting pragmatic language impairment after pediatric TBI is related to younger age at brain insult, as well as microhemorrhagic pathology in brain regions that contribute to the anatomically distributed social brain network. Relationships between reduced pragmatic communication and more frequent externalizing behavior underscore the need for context-sensitive rehabilitation programs that aim to increase interpersonal effectiveness and reduce risk for maladaptive behavior trajectories into the long-term post injury.

Abstract
Childhood and adolescence are critical periods for maturation of neurobiological processes that underlie complex social and emotional behavior including Theory of Mind (ToM). While structural correlates of ToM are well described in adults, less is known about the anatomical regions subsuming these skills in the developing brain or the impact of cerebral insult on the acquisition and establishment of high-level social cognitive skills. This study aimed to examine the differential influence of age-at-insult and brain pathology on ToM in a sample of children and adolescents with traumatic brain injury (TBI). Children and adolescents with TBI (n = 112) were categorized according to timing of brain insult: (i) middle childhood (5-9 years; n = 41); (ii) late childhood (10-11 years; n = 39); and (iii) adolescence (12-15 years; n = 32) and group-matched for age, gender, and socioeconomic status to a typically developing (TD) control group (n = 43). Participants underwent magnetic resonance imaging including a susceptibility-weighted imaging (SWI) sequence 2-8 weeks postinjury and were assessed on a battery of ToM tasks at 6- and 24-months after injury. Results showed that for adolescents with TBI, social cognitive dysfunction at 6- and 24-months postinjury was associated with diffuse neuropathology and a greater number of lesions detected using SWI. In the late childhood TBI group, we found a time-dependent emergence of social cognitive impairment, linked to diffuse neuropathology. The middle childhood TBI group demonstrated performance unrelated to SWI pathology and comparable to TD controls. Findings indicate that the full extent of social cognitive deficits may not be realized until the associated skills reach maturity. Evidence for brain structure-function relationships suggests that the integrity of an anatomically distributed network of brain regions and their connections is necessary for the acquisition and establishment of high-level social cognitive skills.

Abstract
The relationship between brain injury and attentional control (AC) long after a childhood traumatic brain injury (TBI) has received limited investigation. The aim of this article was to investigate the impact that lesion presence, location, and severity has on AC in a group of young persons who had sustained a moderate to severe TBI 10 years earlier during childhood. The participants in this study were a subset of a larger 10-year, follow-up assessment comprised of 31 persons in late adolescence and early adulthood (21 males), with a mean age at testing of 15.4 years (standard error 0.6; range 10.7-21.2 years). Analyses revealed that in regard to AC abilities, the presence of a lesion(s) appears to have a differential effect depending on the testing measure used. When using standardized testing with subtests of the TEA-ch, no differences in performance between those with and those without a lesion at 10 years post-TBI were found. On standardized behavioral measures such as parental reports of perceived AC (Behavior Rating Inventory of Executive Function), however, the presence of a lesion was found to have a detrimental effect on the ability to self-regulate and monitor behavior in late adolescence and the early stages of adulthood. We discuss these results and propose that there is a network of brain regions associated with AC, and generalized lesions have the greatest influence on such abilities.

Abstract
IMPORTANCE Executive dysfunction after traumatic brain injury (TBI) in children is common and leads to significant short- and long-term problems in functioning across multiple settings. We hypothesized that improvements in short-term executive function would be maintained to 24 months after injury and that improvements would increase over time in a counselor-assisted problem-solving (CAPS) intervention. OBJECTIVE To evaluate the efficacy of a CAPS intervention administered within 7 months of complicated mild to severe TBI compared with an Internet resource condition in improving long-term executive dysfunction. DESIGN, SETTING, AND PARTICIPANTS Multisite, assessor-blinded, randomized clinical trial at 3 tertiary pediatric hospitals and 2 tertiary general medical centers. Participants included 132 adolescents aged 12 to 17 years who sustained a moderate to severe TBI 1 to 7 months before study enrollment. INTERVENTION Web-based CAPS intervention. MAIN OUTCOMES AND MEASURES The primary outcome was the parent-reported Global Executive Composite (GEC) of the Behavior Rating Inventory of Executive Function. Secondary outcomes included the Behavioral Regulation Index (BRI) and Metacognition Index (MI) of the GEC. RESULTS In older (>14 to 17 years) adolescents, the CAPS intervention was associated with lower GEC ratings at 12 (β = -0.46; P = .03) and 18 (β = -0.52; P = .02) months after enrollment. Trends were also observed for older adolescents toward lower GEC ratings at 6 months (β = -0.40; P = .05), lower BRI ratings at 12 (β = -0.40; P = .06) and 18 (β = -0.47; P = .04) months, and lower MI ratings at 6 (β = -0.41; P = .05), 12 (β = -0.46; P = .03), and 18 (β = -0.50; P = .03) months. In younger (12-14 years) adolescents, no group differences were found on the GEC, BRI, or MI ratings. CONCLUSIONS AND RELEVANCE Delivery of the CAPS intervention early after TBI in older adolescents improves long-term executive function. This trial is, to our knowledge, one of the few large, randomized clinical treatment trials performed in pediatric TBI to demonstrate the efficacy of an intervention for management of executive dysfunction and long-term benefits of an intervention delivered soon after injury. Use of the CAPS intervention clinically should be considered; however, further research should explore ways to optimize delivery. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00409448.

Abstract
BACKGROUND Childhood head injury has the potential for lifelong disability and burden. This study aimed to establish the association between admission to hospital for childhood head injury and early academic performance. METHODS The Wales Electronic Cohort for Children (WECC) study is comprised of record-linked routinely collected data, on all children born or residing in Wales. Anonymous linking fields are used to link child and maternal health, environment and education records. Data from WECC were extracted for children born between September 1998 and August 2001. A Generalised Estimating Equation model, adjusted for clustering based on the maternal identifier as well as other key confounders, was used to establish the association between childhood head injury and performance on the Key Stage 1 (KS1) National Curriculum assessment administered to children aged 5-7 years. Head injury was defined as an emergency admission for >24 h for concussion, skull fracture or intracranial injury prior to KS1 assessment. RESULTS Of the 101 892 eligible children, KS1 results were available for 90 661 (89%), and 290 had sustained a head injury. Children who sustained an intracranial injury demonstrated significantly lower adjusted odds of achieving a satisfactory KS1 result than children who had not been admitted to hospital for head injury (adjusted OR 0.46, 95% CI 0.30 to 0.72). CONCLUSIONS The findings of this population e-cohort study quantify the impact of head injury on academic performance, highlighting the need for enhanced head injury prevention strategies. The results have implications for the care and rehabilitation of children admitted to hospital with head injury.

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
Traumatic brain injury (TBI) refers to physical trauma to the brain that can lead to motor and cognitive dysfunctions. TBI is particularly serious in infants and young children, often leading to long-term functional impairments. Although clinical research is useful for quantifying and observing the effects of these injuries, few studies have empirically assessed the long-term effects of juvenile TBI (jTBI) on behavior and histology. After a controlled cortical impact delivered to postnatal 17day old rats, functional abilities were measured after 3, 5, and 6months using open field (activity levels), zero maze (anxiety-like behaviors), rotarod (sensorimotor abilities, coordination, and balance), and water maze (spatial learning and memory, swim speed, turn bias). Sensorimotor function was impaired for up to 6months in jTBI animals, which showed no improvement from repeated test exposure. Although spatial learning was not impaired, spatial memory deficits were observed in jTBI animals starting at 3months after injury. Magnetic resonance imaging and histological data revealed that the effects of jTBI were evolving for up to 6months post-injury, with reduced cortical thickness, decreased corpus callosum area and CA1 neuronal cell death in jTBI animals distant to the impact site. These findings suggest that this model of jTBI produces long-term impairments comparable to those reported clinically. Although some deficits were stable over time, the variable nature of other deficits (e.g., memory) as well as changing properties of the lesion itself, suggest that the effects of a single jTBI produce a chronic brain disorder with long-term complications.

Abstract
OBJECTIVE Executive dysfunction after traumatic brain injury (TBI) in children is common and leads to significant problems in functioning across multiple settings. The objective of this study was to evaluate the efficacy of a web-based counselor-assisted problem solving (CAPS) intervention compared with an Internet resource comparison (IRC) for treatment of executive dysfunction within 12 months after complicated mild to severe TBI in adolescents. We hypothesized that CAPS would significantly improve parent ratings of executive dysfunction compared with an IRC. METHODS Participants included 132 adolescents aged 12 to 17 years who sustained a complicated mild to severe TBI within 1 to 6 months before study enrollment. Study design was a multisite, assessor-blinded, randomized controlled trial. Study sites included 3 tertiary pediatric hospitals and 2 tertiary general medical centers. The main outcome measure was primary caregiver Behavioral Rating Inventory of Executive Function Global Executive Composite at baseline and 6-month follow-up. Generalized linear models that controlled for baseline scores were used to compare the CAPS and IRC scores. RESULTS In older teens, the CAPS group showed significant improvement in executive function behaviors at 6-month follow-up compared with the IRC group (F = 6.74, P = .01, Cohen's d = 0.63). CONCLUSIONS Findings indicate that web-based CAPS improves primary caregiver-rated executive functioning within the first 12 months after TBI in older adolescents. Future research needs to define the optimal timing after injury for delivery of CAPS and characteristics of individuals and families who are most likely to benefit from CAPS.
