Rehabilitation models of care for children and youth with traumatic brain and/or spinal cord injuries: A focus on service structure, service organization, and the barriers and facilitators of rehabilitation service provision.

To understand the systems underlying current rehabilitation models of care used with children and youth (0-21years) who sustain traumatic brain and/or spinal cord injuries. This study gathered qualitative data on service structures, service organization, and the barriers and facilitators of service provision in selected medical rehabilitation service(s) (MRS) and community-based rehabilitation service(s) (CBRS). Informants from 11 rehabilitation services were interviewed using a semi-structured interview guide. Interviews were analysed in NVivo using content analysis method. Experiences shared by the service representatives indicated that most services supported children and youth with brain injury, with a limited number also specializing in spinal cord injuries. MRS often delivered care in inpatient or outpatient settings, while CBRS offered home/community-based services. Care planning often started either prior to or shortly after admission from acute care settings, using either multidisciplinary or interdisciplinary teamwork models. Strengths of the services included innovation and provision of family-centred care; while challenges experienced included difficulty translating evidence into practice and poor team communication. Models of care were similar across services, with a focus on providing family-centred care. Several shared challenges were described, and service representatives expressed interest in forming partnerships and collaborations to address these challenges through innovative initiatives.

Self-perception and behavioural outcomes of early acquired brain injury.

Acquired brain injury (ABI) occurs commonly in young children. Despite this, the psychosocial implications of ABI in young children are not established, with little understood about the impacts on self-perception and self-esteem. In this study we investigated self-perception, self-esteem and behaviour of children with early ABI. Children with an ABI (n = 47) before six years were compared to 17 typically developing controls (TDCs) matched on demographics. Children were aged 6-12 years and completed the Harter Self-Perception Profile. One parent completed the Child Behavior Checklist. No differences for self-perception and self-esteem were found between the groups. Parents of children with an early ABI reported more internalizing and externalizing behaviours. Children with more externalizing behaviour and social skill problems had more negative self-perceptions. Interaction effects were seen between socioeconomic status (SES) and child self-perception and behaviour. Specifically, children from families of higher SES had a more positive perception of their appearance and children from lower SES backgrounds had more externalizing behaviours and social problems. The study suggests that the relationship between ABI and self-perception and self-esteem is complicated and that children with behavioural problems have lowered feelings of competence. SES has an important role in self-perception and behavioural outcomes.

Rehabilitation models of care for children and youth living with traumatic brain and/or spinal cord injuries: A focus on family-centred care, psychosocial wellbeing, and transitions.

To describe current rehabilitation models of care and programmes, in Australia and internationally, related to family-centred care, psychosocial support, and transitions used for children and youth who have sustained major traumatic brain and/or spinal cord injuries. Fourteen services were interviewed, including eight medical rehabilitation services, three community-based rehabilitation services, two insurance services, and one state-wide education service provider. Semi-structured interviews were transcribed and analysed using qualitative content analysis in NVivo. Compared to the number of services supporting children and youth with traumatic brain injury, a very limited number supported those with spinal cord injury. Although valued and often included in the model of care, family-centred care was rarely systematically evaluated by the services. Most services provided psychosocial and transition support to children and youth, and their families in the short-term post-injury, but not in the long-term. Several challenges also hindered the smooth delivery of these support services, including poor communication between service providers. These findings show that services aimed to provide the best possible care to these children and youth, and their families; guided by rehabilitation models of care. However, challenges persist with regards to delivering family-centred care, coordinating return to school, and providing long-term support for psychosocial problems and transition.

Fatigue Following Pediatric Arterial Ischemic Stroke: Prevalence and Associated Factors.

Background and Purpose: The aims of this study were to assess the prevalence of multidimensional fatigue symptoms 5 years after pediatric arterial ischemic stroke and identify factors associated with fatigue. Methods: Thirty-one children (19 males) with pediatric arterial ischemic stroke, participating in a larger prospective, longitudinal study, were recruited to this study at 5 years poststroke. Parent- and self-rated PedsQL Multidimensional Fatigue Scale scores were compared with published normative data. Associations between parent-rated PedsQL Multidimensional Fatigue Scale, demographics, stroke characteristics, and concurrent outcomes were examined. Results: Parent-rated total, general and cognitive fatigue were significantly poorer than population norms, with more than half of all parents reporting fatigue symptoms in their children. One-third of children also reported experiencing fatigue symptoms, but their ratings did not differ significantly from normative expectations, as such, all further analyses were on parent ratings of fatigue. Older age at stroke and larger lesion size predicted greater general fatigue; older age, female sex, and higher social risk predicted more sleep/rest fatigue. No significant predictors of cognitive fatigue were identified and only older age at stroke predicted total fatigue. Greater fatigue was associated with poorer adaptive functioning, motor skills, participation, quality of life, and behavior problems but not attention. Conclusions: Fatigue is a common problem following pediatric arterial ischemic stroke and is associated with the functional difficulties often seen in this population. This study highlights the importance of long-term monitoring following pediatric arterial ischemic stroke and the need for effective interventions to treat fatigue in children.

Social Cognitive Dysfunction Following Pediatric Arterial Ischemic Stroke: Evidence From a Prospective Cohort Study.

Background and Purpose: Childhood and adolescence coincide with rapid maturation of distributed brain networks supporting social cognition; however, little is known about the impact of early ischemic brain insult on the acquisition of these skills. This study aimed to examine the influence of arterial ischemic stroke (AIS) on facial emotion recognition and theory of mind (ToM) abilities of children and adolescents initially recruited to a single-center, prospective longitudinal study of recovery following AIS. Methods: The study involved 67 participants, including 30 children with AIS (mean time since stroke=5 years) and 37 age-matched typically developing controls who were assessed on measures of cognitive ToM, facial emotion recognition, and affective ToM. Acute clinical magnetic resonance imaging, including diffusion-weighted imaging sequences, were used to evaluate prospective structure-function relationships between acute lesion characteristics (size, location, and arterial territories affected) and long-term social cognitive abilities. Results: Relative to age-matched typically developing controls, children with AIS showed significantly worse performance on measures of basic facial emotion processing, cognitive ToM, and affective ToM. In univariate models, poorer ToM was associated with larger infarcts, combined cortical-subcortical pathology, and involvement of multiple arterial territories. In multivariate analyses, larger lesions and multiterritory infants were predictive of ToM processing but not facial emotion recognition. Poorer cognitive ToM predicted less frequent prosocial behavior and increased peer problems. Conclusions: Social cognitive skills appear vulnerable to disruption from early ischemic brain insult. In the first study to examine social cognition in a prospective cohort of children with AIS, our findings suggest that acute magnetic resonance imaging-based lesion characteristics may have predictive value for long-term social cognitive outcomes and may assist to identify children at elevated risk for social cognitive dysfunction.

Motor function daily living skills 5 years after paediatric arterial ischaemic stroke: a prospective longitudinal study.

AIM: To describe 5-year motor and functional outcomes after paediatric arterial ischaemic stroke (AIS) and to explore factors associated with poorer long-term outcome. METHOD: Thirty-three children (21 males, 12 females) with AIS were recruited to a single-site, cross-sectional study, from a previously reported prospective longitudinal stroke outcome study. Children were stratified according to age at diagnosis: neonates (≤30d), preschool (>30d-5y), and school age (≥5y). Motor and functional outcomes were measured at 5 years after stroke. Neurological outcomes were evaluated using the Pediatric Stroke Outcome Measure (PSOM) at 1 month and more than 4 years after stroke. RESULTS: At 5 years after stroke, motor function, quality of life, fatigue, adaptive behaviour, activities of daily living, and handwriting speed were significantly poorer than age expectations. The preschool group had the highest percentage of fine and gross motor impairment. Poorer fine motor skills were associated with subcortical-only lesions and large lesion size. Poorer gross motor outcomes correlated with preschool age, bilateral lesions, and PSOM impairment at 1 month. INTERPRETATION: Children are at elevated risk for motor and functional impairments after AIS, with the preschool age group most vulnerable. Identifying early predictors of poorer outcomes facilitates targeted early intervention and long-term rehabilitation. WHAT THIS PAPER ADDS: Following paediatric stroke, children are at elevated risk of motor and functional difficulties. Stroke occurring between 30 days and 5 years of age may result in poorer motor and functional outcomes.

Predicting Fatigue 12 Months after Child Traumatic Brain Injury: Child Factors and Postinjury Symptoms.

OBJECTIVES: Fatigue is a common and persisting symptom after childhood brain injury. This study examined whether child characteristics and symptomatology preinjury or 6 months postinjury (pain, sleep, and mood, inattention) predicted fatigue at 12months postinjury. METHODS: Parents of 79 children (0-18 years) rated fatigue at 12 months after injury on a multidimensional scale (general, sleep/rest, and cognitive). Demographic and clinical data were collected at injury. Parents rated child sleep, pain, physical/motor function, mood, and inattention at injury (preinjury description), and 6 months postinjury. Children were divided into two traumatic brain injury severity groups: mild TBI (n=57) and moderate/severe TBI (n=27). Hierarchical regression models were used to examine (i) preinjury factors and (ii) symptoms 6 months postinjury predictive of fatigue (general, sleep/rest, and cognitive) at 12 months postinjury. RESULTS: Sleep/rest fatigue was predicted by preinjury fatigue (7% of variance) and psychological symptoms preinjury (10% of variance). General fatigue was predicted by physical/motor symptoms (27%), sleep (10%) and mood symptoms (9%) 6 months postinjury. Sleep/rest fatigue was predicted by physical/motor symptoms (10%), sleep symptoms (13%) and mood symptoms (9%) 6 months postinjury. Cognitive fatigue was predicted by physical/motor symptoms (17%) 6 months postinjury. CONCLUSIONS: Preinjury fatigue and psychological functioning identified those at greatest risk of fatigue 12 months post-TBI. Predictors of specific fatigue domains at 12 months differed across each of the domains, although consistently included physical/motor function as well as sleep and mood symptoms postinjury. (JINS, 2018, 24, 224-236).

Fatigue Following Traumatic Brain Injury in Children and Adolescents: A Longitudinal Follow-Up 6 to 12 Months After Injury.

BACKGROUND: Longitudinal fatigue data in children suffering from traumatic brain injury (TBI) are lacking. OBJECTIVES: To examine the effects of time postinjury (6-12 months) and injury severity on fatigue after childhood TBI. Secondarily, we compared fatigue 12 months postinjury against published control data. SETTING: Three tertiary children's hospitals across Australia (n = 1) and Canada (n = 2). PARTICIPANTS: Parents (n = 109) of children (mean [M] = 9.9 years at injury; range, 1.0-16.9 years) admitted to one of 3 participating hospitals with mild (n = 69) or moderate/severe (n = 37) TBI. DESIGN: Longitudinal prospective study. MEASURES: Primary: Pediatric Quality of Life Multidimensional Fatigue Scale (total, general, sleep/rest, and cognitive), rated by parents 6 and 12 months postinjury. Secondary: Pediatric Injury Functional Outcome Scale (fatigue and sleep items, rated on recruitment and 6 and 12 months postinjury). Demographic and children data were collected at recruitment. RESULTS: Mixed-models analysis demonstrated nonsignificant effects of time (6 vs 12 months postinjury) on multidimensional fatigue scores. Cognitive fatigue worsened over time. Moderate/severe TBI was associated with worse fatigue 12 months postinjury (general, P = .03; cognitive, P = .02). Across all severities, fatigue 12 months postinjury was significantly worse compared with control data (total fatigue, P < .001; all domains, all Ps < .025). CONCLUSION: Fatigue remains significant at 12 months since injury, particularly for those with moderate/severe TBI.

Improving cognitive outcomes for pediatric stroke.

PURPOSE OF REVIEW: The past 20 years have seen a 35% increase in prevalence of pediatric stroke. Contrary to widely held views, children do not recover better than adults. This review explores the impact of pediatric stroke on cognitive domains, including intellectual and executive functions, memory and behavior, and the influence of age, lesion characteristics, and comorbidities on outcome. RECENT FINDINGS: Cognitive problems occur in up to half of ischemic and hemorrhagic stroke survivors. Single-center studies have shown intelligence quotient scores skewed to the lower end of the average range, with greater impairment in performance than verbal domains. Executive function, such as attention and processing speed are particularly vulnerable to the effects of pediatric stroke. Age at stroke, larger infarct size, cortical/subcortical lesion location, epilepsy, and comorbid physical deficits are associated with poorer cognitive outcomes. SUMMARY: Cognitive impairment occurs relatively frequently following pediatric stroke but the nature, severity, and predictors of specific deficits are not well defined. Improving understanding of outcomes following pediatric stroke is a key priority for families but a paucity of data limits the ability to develop targeted disease, and age-specific pediatric rehabilitation strategies to optimize cognitive outcomes following pediatric stroke.

Profiles of Executive Function Across Children with Distinct Brain Disorders: Traumatic Brain Injury, Stroke, and Brain Tumor.

OBJECTIVES: This study examined whether children with distinct brain disorders show different profiles of strengths and weaknesses in executive functions, and differ from children without brain disorder. METHODS: Participants were children with traumatic brain injury (N=82; 8-13 years of age), arterial ischemic stroke (N=36; 6-16 years of age), and brain tumor (N=74; 9-18 years of age), each with a corresponding matched comparison group consisting of children with orthopedic injury (N=61), asthma (N=15), and classmates without medical illness (N=68), respectively. Shifting, inhibition, and working memory were assessed, respectively, using three Test of Everyday Attention: Children's Version (TEA-Ch) subtests: Creature Counting, Walk-Don't-Walk, and Code Transmission. Comparison groups did not differ in TEA-Ch performance and were merged into a single control group. Profile analysis was used to examine group differences in TEA-Ch subtest scaled scores after controlling for maternal education and age. RESULTS: As a whole, children with brain disorder performed more poorly than controls on measures of executive function. Relative to controls, the three brain injury groups showed significantly different profiles of executive functions. Importantly, post hoc tests revealed that performance on TEA-Ch subtests differed among the brain disorder groups. CONCLUSIONS: Results suggest that different childhood brain disorders result in distinct patterns of executive function deficits that differ from children without brain disorder. Implications for clinical practice and future research are discussed. (JINS, 2017, 23, 529-538).

Psychosocial function in the first year after childhood stroke.

AIM: Childhood stroke disrupts brain development and emerging neural networks. Motor, cognitive, and language deficits are well recognized, yet little is known about psychosocial function after childhood stroke. This study aims to describe psychosocial function within the first year after childhood stroke, and to identify factors associated with outcome. METHOD: Thirty-seven children were involved in a prospective, longitudinal study investigating recovery over the first year after childhood stroke. Children's social functioning was assessed at 6-months and 12-months poststroke and psychological function at 12-months poststroke, using standardized measures. RESULTS: Mean social function was poorer at both 6-months and 12-months poststroke, compared to prestroke. Psychological problems were more common than expected, with emotional difficulties and hyperactivity-inattention most significantly affected. Poorer social function was associated with older age at onset, acute neurological impairment, and prestroke social impairment. Social and psychological problems were associated with parent mental health. INTERPRETATION: While not all children are affected, psychosocial impairment affects a significant minority after childhood stroke. Older age at onset, acute neurological impairment, prestroke social problems, and poorer parent mental health were associated with deficits. Identifying early predictors of poorer outcome will facilitate early intervention. Of particular importance is parent mental health, suggesting support for families may improve child outcome.

Early predictors of psychosocial functioning 5 years after paediatric stroke.

AIM: Little is known about psychological and social outcomes after paediatric stroke. This study aimed to evaluate psychosocial outcomes in children 5 years after paediatric stroke and explore the contribution of early presenting factors. METHOD: Thirty-one children (19 males, 12 females) with arterial ischemic stroke were involved in this prospective, longitudinal study. Children underwent intellectual assessment at 12 months poststroke and parents completed questionnaires rating their own mental health and their child's functioning at 12 months and 5 years poststroke. RESULTS: At 5-year follow-up, psychological and social function were significantly poorer than normative expectations. Exploration of early predictive factors showed poorer cognitive and psychological function at 12 months poststroke and older age at stroke onset was associated with poorer psychosocial function at 5 years. Larger lesion size was also associated with poorer psychological function at 5 years poststroke. INTERPRETATION: These early predictors of poorer psychosocial outcome suggest that screening children within the first year after stroke may identify children most at risk of later problems and facilitate early intervention.

Prediction of Multidimensional Fatigue After Childhood Brain Injury.

OBJECTIVES: To determine (1) the presence of fatigue symptoms and predictors of fatigue after childhood brain injury and examine (2) the feasibility, reliability, and validity of a multidimensional fatigue measure (PedsQL Multidimensional Fatigue Scale [MFS]) obtained from parent and child perspectives. SETTING: Emergency and intensive care units of a hospital in Melbourne, Australia. PARTICIPANTS: Thirty-five families (34 parent-proxies and 32 children) aged 8 to 18 years (mean child age = 13.29 years) with traumatic brain injury (TBI) of all severities (27 mild, 5 moderate, and 3 severe) admitted to the Royal Children's Hospital. DESIGN: Longitudinal prospective study. Fatigue data collected at 6-week follow-up (mean = 6.9 weeks). MAIN OUTCOME MEASURES: Postinjury child- and parent-rated fatigue (PedsQL MFS), mood, sleep, and pain based on questionnaire report: TBI severity (mild vs moderate/severe TBI). RESULTS: A score greater than 2 standard deviations below healthy control data indicated the presence of abnormal fatigue, rates of which were higher compared with normative data for both parent and child reports (47% and 29%). Fatigue was predicted by postinjury depression and sleep disturbance for parent, but not child ratings. Fatigue, as rated by children, was not significantly predicted by TBI severity or other symptoms. The PedsQL MFS demonstrated acceptable measurement properties in child TBI participants, evidenced by good feasibility and reliability (Cronbach α values >0.90). Interrater reliability between parent and child reports was poor to moderate. CONCLUSIONS: Results underscore the need to assess fatigue and associated sleep-wake disturbance and depression after child TBI from both parent and child perspectives.

Predicting neurocognitive and behavioural outcome after early brain insult.

AIMS: The aims of the study were to investigate (1) the impact of age at brain insult on functional outcome and (2) the influence of insult and environmental factors on cognitive and behavioural outcomes. METHOD: The study was a cross-sectional, retrospective observational study, involving 138 children (76 males, 62 females; mean age 13y 1mo, SD 1y 11mo, range 10­16y) with magnetic resonance imaging (MRI) evidence of focal brain insult sustained from the first trimester of pregnancy to adolescence. Children underwent MRI and intellectual, executive, behavioural, and social evaluation. Outcome predictors were insult (lesion location, laterality, and extent, history of seizures, age at insult) and environmental (social risk and family function) factors. RESULTS: Focal insult before the age of 3 years was associated with poorer outcomes than insult after the age of 3 years across all domains. For IQ outcomes, insult characteristics and seizures were highly predictive. For executive and behavioural domains, family function and social risk had the greatest impact. Earlier age at insult predicted poorer social competence. INTERPRETATION Focal brain insult before age 3 years has devastating consequences for children's development. Findings suggest that greater emphasis should be placed on providing early intervention for children who sustain early focal brain insults.

Deep phenotyping of socio-emotional skills in children with typical development, neurodevelopmental disorders, and mental health conditions: Evidence from the PEERS.

OBJECTIVE: Socio-emotional skills, including social competence and social cognition, form the basis for robust relationships and wellbeing. Despite their importance, these skills are poorly defined and measured, particularly in children with developmental vulnerabilities. As a consequence, targets for effective management and treatment remain unclear. We aimed to i) phenotype social competence and social cognition in typically developing children (TDC) and in children with neurodevelopmental or mental health disorders (clinical groups) and ii) establish the relationships between these child-direct measures and parent ratings of social competence and behavior. METHOD: Using a multi-site, cross-sectional study design, we recruited 513 TDC and 136 children with neurodevelopmental (autism spectrum disorder [ASD], attention deficit hyperactivity disorder [ADHD]) or mental health (Anxiety Disorder [ANX]) diagnoses (age range 5-15 years). We administered the Paediatric Evaluation of Emotions, Relationships and Socialisation (PEERS) to children, and parents completed standardised questionnaires rating children's socio-emotional function. RESULTS: Standardised parent questionnaires revealed a global pattern of everyday socio-emotional impairment that was common to all clinical groups, while PEERS identified disorder-specific socio-cognitive profiles for children with ASD, ADHD and ANX. Compared to TDCs, children with ASD demonstrated global socio-cognitive impairment. Children with ADHD were impulsive, demonstrating difficulties managing speed accuracy trade-offs. Children with ANX exhibited slowed social decision-making, but otherwise intact skills. CONCLUSIONS: Standardized parent questionnaires of child socio-emotional function reveal differences between children with typical and atypical development, but do not yield disorder-specific, socio-emotional profiles. In contrast, findings from the PEERS objective assessment suggest that that ASD, ADHD and ANX are associated with distinct socio-cognitive phenotypes, to more accurately guide and target management and treatment of impaired social competence.

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

OBJECTIVE: Review the literature on predictors of participation and quality of life in children and young people who sustained a traumatic brain injury (TBI), spinal cord injury (SCI), and/or multi-trauma in a motor vehicle or other accident or trauma. DESIGN: This systematic review was conducted and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The protocol was registered on PROSPERO (registration number CRD42020131698). Electronic databases were searched for studies published between January 2000 and August 2020. Prospective and retrospective cohort studies were considered and risk of bias was assessed using the Quality In Prognosis Studies (QUIPS) tool. RESULTS: The search yielded 5771 articles of which 30 studies met the inclusion criteria. Nineteen studies included patients with TBI and 11 with SCI. No studies of patients with multi-trauma met criteria. Evidence was found for associations with various factors (e.g., injury severity, level of education, mental health problems), although these findings are limited due to the quality of the studies (5 studies moderate and 25 high risk of bias). CONCLUSION: Research on predictors of participation and quality of life following major traumatic injuries in childhood is lacking. More methodologically sound prospective, longitudinal studies are needed across different injury groups to further elucidate predictors of outcome.IMPLICATIONS FOR REHABILITATIONWhile long-term participation and quality of life is influenced by injury characteristics (i.e., injury severity), a number of potential modifiable factors can be targeted to improve outcomes following traumatic injuries in childhood.Young people should be provided with support to stay in school and pursue further education.Early intervention and prevention of mental health problems may improve long-term outcomes.Better management of ongoing medical problems and greater support for functional independence may improve participation.

Interleukin-8 Predicts Fatigue at 12 Months Post-Injury in Children with Traumatic Brain Injury.

Despite many children experiencing fatigue after childhood brain injury, little is known about the predictors of this complaint. To date, traditional indices of traumatic brain injury (TBI) severity have not predicted reliably persisting fatigue (up to three years post-injury). This study aimed to establish whether persisting fatigue is predicted by serum biomarker concentrations in child TBI. We examined whether acute serum biomarker expression would improve prediction models of 12-month fatigue based on injury severity. Blood samples were collected from 87 children (1-17 years at injury) sustaining mild to severe TBI (Glasgow Coma Scale [GCS] range 3-15; mean 12.43; classified as mild TBI [n = 50, 57%] vs. moderate/severe TBI [n = 37, 43%]), and presenting to the emergency departments (ED) and pediatric intensive care units (PICU) at one of three tertiary pediatric hospitals (Royal Children's Hospital (RCH); Hospital for Sick Children (HSC), Toronto; St Justine Children's Hospital (SJH), Montreal). Six serum biomarker concentrations were measured within 24 h of injury (interleukin-6, interleukin-8 [IL-8], soluble vascular cell adhesion molecule [SVCAM], S100 calcium binding protein B [S100B], neuron specific enolase [NSE], and soluble neural cell adhesion molecule [sNCAM]). Fatigue at 12 months post-injury was measured using the Pediatric Quality of Life Inventory Multidimensional Fatigue Scale (parent report), classified as present/absent using previously derived cut-points. At 12 months post-injury, 22% of participants experienced fatigue. A model including IL-8 was the best serum biomarker for estimating the probability of children experiencing fatigue at 12 months post-injury. The IL-8 also significantly improved predictive models of fatigue based on severity.

Childhood brain insult: can age at insult help us predict outcome?

Until recently, the impact of early brain insult (EBI) has been considered to be less significant than for later brain injuries, consistent with the notion that the young brain is more flexible and able to reorganize in the context of brain insult. This study aimed to evaluate this notion by comparing cognitive and behavioural outcomes for children sustaining EBI at different times from gestation to late childhood. Children with focal brain insults were categorized according to timing of brain insult, represented by six developmental periods: (i) Congenital (n = 38): EBI: first-second trimester; (ii) Perinatal (n = 33); EBI: third trimester to 1 month post-natal; (iii) Infancy (n = 23): EBI: 2 months-2 years post-birth; (iv) Preschool (n = 19): EBI: 3-6 years; (v) Middle Childhood (n = 31): EBI: 7-9 years; and (vi) Late Childhood (n = 19): EBI: after age 10. Groups were similar with respect to injury and demographic factors. Children were assessed for intelligence, academic ability, everyday executive function and behaviour. Results showed that children with EBI were at increased risk for impairment in all domains assessed. Furthermore, children sustaining EBI before age 2 years recorded global and significant cognitive deficits, while children with later EBI performed closer to normal expectations, suggesting a linear association between age at insult and outcome. In contrast, for behaviour, children with EBI from 7 to 9 years performed worse than those with EBI from 3 to 6 years, and more like those with younger insults, suggesting that not all functions share the same pattern of vulnerability with respect to age at insult.
