Behavior problems 7 years after severe childhood traumatic brain injury: Results of the Traumatisme Grave de L'Enfant study.

To investigate the occurrence of behavioral problems 7 years after severe pediatric traumatic brain injury (TBI), and their evolution from 3 months to 7 years postinjury. Thirty-four participants, 38% girls, M (SD) age at injury 7.6 (4.7) years, age at assessment 15 (4.6) years, underwent comprehensive assessments 7 years after severe TBI from March 2014 to March 2016 and were matched to a control group by age, gender, and parental education. A subgroup of 20 participants had available behavioral assessments at 3, 12, and 24 months postinjury. Internalizing, externalizing, and total behavioral problems were assessed with self- and parent reports of the Achenbach's Behavioral Checklist. Additional data included sociodemographic background, initial injury severity, and specific outcomes assessed concurrently 7 years postinjury. Compared to controls: (a) a significant proportion of participants with severe TBI fell above the clinical cutoff for self- (42%) and parent-reported (36%) externalizing problems, but not for self- (33%) or parent-reported (45%) internalizing problems; (b) withdrawn/depressed, intrusive behavior, and somatic complaints were significantly higher in self-reports; and (c) rule-breaking behavior, attention, and social problems were significantly higher in parent reports. Parent-reported internalizing problems were associated with older age at injury, whereas externalizing problems correlated with greater injury severity and concurrent levels of greater overall disability, lower intellectual ability, and poorer family functioning. In multiple hierarchical regression analyses, overall disability and worse family functioning significantly predicted externalizing problems. Parent-reported internalizing and externalizing problems persisted over time. These results highlight the importance of long-term follow-up and individualized behavioral interventions for children who sustained severe TBI.

Long-term burden of informal caregiver 7-years after severe childhood traumatic brain injury in the traumatisme grave de l’Enfant (TGE) study

ABSTRACT Objective To investigate reported burden by the Primary Family Caregiver (PFC) 7-years after severe pediatric traumatic brain injury in the TGE (Traumatisme Grave de l’Enfant) longitudinal study. Methods Subjective burden was estimated with the Zarit Burden Inventory (ZBI) in 36 PFC (parents), who rated their own health status (Medical Outcome Study Short Form-12), family functioning and their child’s level of care and needs (Pediatric/Adult Care And Needs Scale [PCANS/CANS]). Data collection included: child and PFC sociodemographic characteristics, injury-related factors, ‘objective’ (e.g. overall level of disability: Glasgow Outcome Scale – Extended, GOS-E/GOS-E-Peds) and ‘subjective’ outcomes (e.g. participation, behavior, executive functions, quality of life and fatigue). Results 25% of PFC reported mild-moderate burden, and 19% moderate-severe burden. Higher burden correlated with worse outcomes in all ‘subjective’ PFC-rated outcomes, and with self-reported participation. The ZBI correlated strongly with CANS/PCANS and GOS-E/GOS-E-Peds. Overall level of disability and PFC-reported executive functioning explained 62% of the ZBI variance. For equal levels of disability, burden was higher when PFC reported a ‘negative’ picture of their child. Conclusion Significant PFC-reported burden 7-years post-injury was associated with overall disability and ‘subjective’ PFC-rated outcomes. Factors influencing parental burden in the long term should be identified and psychological support implemented over time.

Parental report of levels of care and needs 7-years after severe childhood traumatic brain injury: Results of the traumatisme grave de l’Enfant (TGE) cohort study

This study investigated parental reports of the level of care and needs 7-years following severe childhood traumatic brain injury (TBI), and the factors associated with this outcome. From the 65 children (0–15 years) consecutively admitted to the Parisian regional TBI reference intensive care unit following severe TBI, included in this prospective longitudinal study, 39 patients [M(SD) age at injury = 7.5 years (4.6) and assessment 15.3(4.4)] were followed 7-years post-injury and matched with a control group composed of typically developing participants (n = 34) matched by age, sex and parental education level. We used the Care and Need Scale (CANS) and its Pediatric version (PCANS) to assess the primary outcome 7-years post-injury. Concurrent measures included overall level of disability, and parent- and/or self-reported questionnaires assessing executive functioning, behavior, quality of life, fatigue, participation and caregivers’ burden. The level of care and needs was significantly higher in the TBI group than in the control group, the difference being significant with the CANS only. PCANS scores were extremely variable in the control group. High level of dependency was associated with initial TBI severity (higher coma duration and initial Injury Severity Score), higher levels of behavioral problems, executive function deficits, fatigue, and lower participation levels. Caregivers’ burden was strongly associated with the CANS. The CANS provides a simple and reliable measure of the support needed long-term after childhood TBI, in accordance with previous studies. The PCANS scores were not significantly different between the TBI and the control groups, which seems to illustrate the difficulty to assess accurately mild-to-moderate deficits of functional independence/adaptive behavior in children based exclusively on parental reports.

Functional status 1 year after severe childhood traumatic brain injury predicts 7-year outcome: Results of the TGE study.

Childhood severe traumatic brain injury (TBI) is a leading cause of long-lasting acquired disability, but predicting long-term functional outcome remains difficult. This study aimed to 1) describe the functional outcome at 1 and 7 years post-TBI; 2) determine the initial and concurrent factors associated with long-term outcome; and 3) evaluate the predictive value of functional status, overall disability level and intellectual ability measured at 1 year post-injury to determine 7-year clinically meaningful outcomes. Among the children (<16 years) consecutively included over 3 years in the Traumatisme Grave de l'Enfant (TGE) prospective longitudinal cohort study after accidental severe TBI, we studied the outcomes of 39 survivors at 1 and 7 years post-injury. Overall outcome included disability level (Glasgow Outcome Scale), functional status (Pediatric Injury Functional Outcome Scale), intellectual ability (Wechsler scales), executive functions (Behavior Rating Inventory of Executive Functions), behavior (Child Behavior Checklist) as well as neurological impairments and academic status. Mean (SD) age of the 39 survivors at injury was 7.6 (4.6) years, and long-term evaluation was conducted at a mean of 7.8 years post-injury (range 5.9-9.3); 36% of participants were adults (≥18 years old). Most of the neurological impairments remained stable beyond 1 year after TBI, whereas overall disability level improved significantly from 1 to 7 years but remained highly variable, with almost half of participants presenting significant disability levels (moderate: 26%, or severe: 21%). Almost half of participants had significant cognitive, behavior and/or academic difficulties at 7 years post-TBI. On multivariate regression analysis, functional impairment at 1 year was the best predictor of severe disability at 7 years (F(3,31)=13.18, p <0.001, sensitivity=100%, specificity=78%). Our results confirm the significant long-term impact of childhood severe TBI. All children with TBI should benefit from systematic follow-up, especially those with persistent functional deficits at 1 year post-injury, because the severity of functional impairment at 1 year seems the best predictor of long-term significant disability up to 7 years post-TBI.

Memory functioning 7 years after severe childhood traumatic brain injury: Results of the Traumatisme Grave de l'Enfant study.

To explore memory functioning 7 years after severe paediatric traumatic brain injury (TBI), associated factors, and relationships with other outcomes. Children aged 0-15 years (n = 65), consecutively admitted over a 3-year period in a single trauma centre, who survived after severe non-inflicted TBI, were included in a prospective longitudinal study. Memory assessments were performed 7 years post-injury using the Children's Memory Scale or the Wechsler Memory Scale (WMS IV), according to age. The General Memory Score (GMS-7) was the primary outcome. Thirty-seven patients were available for assessment at 7 years post-injury. Mean GMS-7 was in the low average range (M = 84.9, SD = 12.1). Lower GMS-7 was significantly associated with markers of higher injury severity, such as length of coma. One year post-injury functional and disability outcomes explained 74% of the variance of GMS-7. Concurrent intellectual ability and type of ongoing education correlated strongly with GMS-7. Age at injury and parental education were not associated with memory outcome. Memory functioning is variable but often strongly impaired several years after severe paediatric TBI, and is mostly related to injury severity, functional outcomes measured 1 year post-injury, and concomitant cognitive and educational outcomes. GMS-7 was lower at 7 years than one year post-injury, supporting the importance of long term follow-up.

Functional outcome after severe childhood traumatic brain injury: Results of the TGE prospective longitudinal study.

Childhood severe traumatic brain injury (TBI) is a leading cause of long-lasting acquired disability, but little is known about functional outcome. We aimed to 1) study clinical recovery and functional outcome over 24 months after severe childhood TBI, 2) identify early sociodemographic and severity factors influencing outcome, and 3) examine the clinical utility of the Pediatric Injury Functional Outcome Scale (PIFOS) to assess functional outcome. Children (0-15 years) consecutively admitted in a trauma centre after accidental severe TBI over 3 years were included in a prospective longitudinal study (Traumatisme Grave de l'Enfant cohort). We measured clinical/neurological recovery, functional status (Pediatric Injury Functional Outcome Scale, [PIFOS]), overall disability (pediatric Glasgow Outcome Scale [GOS-Peds]) as well as intellectual ability (Wechsler scales) and educational outcome (mainstream school vs special education) of survivors at 1, 3, 12 and 24 months post-injury. For 45 children (aged 3 to 15 years at injury), functional impairments were severe within the first 3 months. Despite the initial rapid clinical recovery and significant improvement over the first year, substantial alterations persisted for most children at 12 months post-TBI, with no significant improvement up to 2 years. Up to 80% of children still had moderate or severe overall disability (GOS-Peds) at 24 months. The severity of functional impairments (PIFOS) at 12 and 24 months was mostly related to socio-emotional, cognitive and physical impairments, and was significantly correlated with clinical/neurological deficits and cognitive (intellectual, executive) and behavioural disorders. Initial TBI severity was the main prognostic factor associated with functional status over the first 2 years post-injury. Our results confirm the significant impact of severe childhood TBI on short- and medium-term functional outcomes and overall disability. All patients should benefit from systematic follow-up. The PIFOS appeared to be an accurate and reliable tool to assess functional impairment evolution and clinically meaningful outcomes over the first 2 years post-injury.

Self- and Parent-Reported Fatigue 7 Years After Severe Childhood Traumatic Brain Injury: Results of the Traumatisme Grave de l'Enfant Prospective Longitudinal Study.

To investigate presence of and factors associated with self- and parent-reported fatigue 7 years after severe childhood traumatic brain injury (TBI) in the prospective longitudinal study TGE (Traumatisme Grave de l'Enfant-severe childhood trauma). Self-reports and/or parent reports on the Multidimensional Fatigue Scale were collected for 38 participants (aged 7-22 years) 7 years after severe childhood TBI, and 33 controls matched for age, gender, and parental educational level. The data collected included sociodemographic characteristics, age at injury and injury severity scores, overall disability (Glasgow Outcome Scale Extended), intellectual outcome (Wechsler scales), and questionnaires assessing executive functions, health-related quality of life, behavior, and participation. Fatigue levels were significantly worse in the TBI than in the control group, especially for cognitive fatigue. Correlations of reported fatigue with age at injury, gender, TBI severity, and intellectual ability were moderate and often not significant. Fatigue was significantly associated with overall level of disability (Glasgow Outcome Scale Extended) and with all questionnaires completed by the same informant. High levels of fatigue were reported by 30% to 50% of patients 7 years after a severe childhood TBI. Reported fatigue explained more than 60% of the variance of reported health-related quality of life by the same informant (patient or parent).

Executive functions and attention 7years after severe childhood traumatic brain injury: Results of the Traumatisme Grave de l'Enfant (TGE) cohort.

Severe childhood traumatic brain injury (TBI) leads to long-standing executive function and attention deficits, with negative consequences for participation, academic outcome and independence. This study aimed to assess executive function and attention 7years after severe childhood TBI in comparison with a matched control group and to investigate associated factors. Children (<15years) with severe accidental TBI consecutively admitted in a single trauma center over 3years were included in the Traumatisme Grave de l'Enfant (TGE) prospective longitudinal study. Of the 81children initially included, 65survived. At 7years post-TBI, executive functions and attention were assessed in 27participants (42% of the 65survivors) by using a combination of computerized tasks from the Test of Attentional Performance (TAP) and the Behavioral Rating of Executive Functions (BRIEF) questionnaire. Patients were compared to a group of 27typically developing controls who were matched for sex, age and parental education level. Among the 27participants, mean (SD) age at injury was 7.7 (4.6)years, and mean length of coma 5.6 (4.6) days. Regarding the TAP, the number of errors was significantly higher (P=0.003) and reaction time marginally slower (P=0.08) in the TBI than control group. The BRIEF questionnaire completed by parents indicated significantly more executive difficulties in the TBI than control group (Behavior Regulation Index, P=0.005; Metacognitive index, P=0.02; Global Executive Composite, P=0.012). Correlations between BRIEF and TAP scores did not reach statistical significance. BRIEF total score was correlated moderately with length of coma (r=0.40, P=0.037), and TAP scores were correlated with the Full-Scale Intellectual Quotient (total number of errors: r=-0.48; P=0.01; mean reaction time: r=-0.51; P=0.009). Executive and attention deficits were evident 7years after severe childhood TBI. Computerized tasks and questionnaires provide complementary and non-redundant information. Systematic long-term follow-up should be provided until the transition to adulthood, to assess ongoing development and to implement timely tailored interventions.

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

To investigate self- and parent-reported Health-Related Quality-of-Life (HRQoL) and their associations after severe childhood traumatic brain injury (TBI) in the Traumatisme Grave de l'Enfant (TGE) cohort. Self-(n = 34) and/or parent-reports (n = 25) of HRQoL were collected for 38 participants (age 7-22years) 7years after severe childhood TBI. The collected data included sociodemographic characteristics, injury severity indices, and overall disability and functional outcome at 3-months, 1- and 2-years post-injury. At 7-years post-injury, data were collected in the TBI group and in a control group (n = 33): overall disability (Glasgow Outcome Scale Extended), intellectual ability (IQ), and questionnaires assessing HRQoL (Pediatric Quality of Life Inventory), executive functions (Behavior Rating Inventory of Executive Functions), behavior (Child Behavior Checklist), fatigue (Multidimensional Fatigue Scale) and participation (Child and Adolescent Scale of Participation). Parent- and self-reports of HRQoL were significantly lower in the TBI group than in the control group. Parent-rated HRQoL was not associated with objectively assessed factors, whereas self-reported HRQoL was associated with gender (worse in females) and initial functional outcome. All questionnaire scores completed by the same informant (self or parent) were strongly inter-correlated. Reported HRQoL 7-years after severe childhood TBI is low compared to controls, weakly or not-related to objective factors, such as injury severity indices, clinically assessed functional outcomes, or IQ, but strongly related to reports by the same informant of executive deficits, behavior problems, fatigue, and participation.

Pituitary deficiency and precocious puberty after childhood severe traumatic brain injury: a long-term follow-up prospective study

Objectives Childhood traumatic brain injury (TBI) is a public health issue. Our objectives were to determine the prevalence of permanent pituitary hormone deficiency and to detect the emergence of other pituitary dysfunctions or central precocious puberty several years after severe TBI. Design Follow-up at least 5 years post severe TBI of a prospective longitudinal study. Patients Overall, 66/87 children, who had endocrine evaluation 1 year post severe TBI, were included (24 with pituitary dysfunction 1 year post TBI). Main outcome measures In all children, the pituitary hormones basal levels were assessed at least 5 years post TBI. Growth hormone (GH) stimulation tests were performed 3-4 years post TBI in children with GH deficiency (GHD) 1 year post TBI and in all children with low height velocity (<-1 DS) or low IGF-1 (<-2 DS). Central precocious puberty (CPP) was confirmed by GnRH stimulation test. Results Overall, 61/66 children were followed up 7 (5-10) years post TBI (median; (range)); 17/61 children had GHD 1 year post TBI, and GHD was confirmed in 5/17 patients. For one boy, with normal pituitary function 1 year post TBI, GHD was diagnosed 6.5 years post TBI. 4/61 patients developed CPP, 5.7 (2.4-6.1) years post-TBI. Having a pituitary dysfunction 1 year post TBI was significantly associated with pituitary dysfunction or CPP more than 5 years post TBI. Conclusion Severe TBI in childhood can lead to permanent pituitary dysfunction; GHD and CPP may appear after many years. We recommend systematic hormonal assessment in children 1 year after severe TBI and a prolonged monitoring of growth and pubertal maturation. Recommendations should be elaborated for the families and treating physicians.

Assessment of memory functioning over two years following severe childhood traumatic brain injury: results of the TGE cohort

ABSTRACTThe aims of this study were (1) to prospectively measure memory functioning following severe childhood Traumatic Brain Injury (TBI), and its evolution over 2 years; (2) to assess demographic and medical factors associated with memory function and recovery; (3) to explore relations between memory and other TBI outcomes.Methods: Children (aged 0–15 years; n= 65) consecutively admitted in a single trauma center over a 3-year period, who survived severe non-inflicted TBI, were included in a prospective longitudinal study. Memory was assessed in 38 children aged 5–15 years at injury, using the Children’s Memory Scale at 3, 12, and 24 months post-injury.Results: Mean general memory score was low at 3 months (M = 90.2, SD = 20.3) but within the normal range at 12 and 24 months (M = 100.6, SD = 23.1 and M = 108.6, SD = 24.1, respectively), with high variability. Improvement was stronger for immediate visual memory than for other memory indices. Lower general memory score was associated with higher injury severity, lower intellectual ability and functional status, higher overall disability, and ongoing education.Conclusion: Memory functioning is highly variable following severe childhood TBI, related to injury severity and functional, cognitive and educational outcomes; improvement is significant during the first-year post-injury, but varies according to the type of memory.

Participation seven years after severe childhood traumatic brain injury

Purpose: Participation in home, school and community activities is considered as the ultimate aim of rehabilitation. The aims of this study were to examine participation seven years post-severe childhood traumatic brain injury and factors associated with participation.Materials and methods: Participants were enrolled in the Traumatisme Grave de l’Enfant (Severe Childhood Injury) cohort study following severe accidental childhood traumatic brain injury. Participation seven years post-injury, was examined using parent- and self-report forms of the Child and Adolescent Scale of Participation among 37 patients [62% males, mean age 15.4 years (SD = 4.4), mean length of coma 6.68 days (SD = 4.96)] and 33 matched controls.Results: Parent reports indicated significantly lower participation among patients compared to controls, but the self-reports did not. In the traumatic brain injury group, parent-reported participation was variable, with 22% of the patients clearly showing greater restrictions than controls. Participation restrictions were significantly associated with injury severity, poor functional outcome one-year post-injury, executive and behavioral difficulties and higher fatigue levels seven years post-injury, but not with pre-injury nor family factors.Conclusions: Several years after severe childhood traumatic brain injury, participation appears to depend more on injury-related factors than on environmental factors. In self-reports assessments of participation, it could be difficult for children and adolescents to distinguish capacity from performance.Implications for rehabilitationParticipation outcomes were highly variable in a sample of patients who sustained severe childhood traumatic brain injury.Participation should be assessed systematically following severe traumatic brain injury, both initially but also in the long-term, ideally using a combination of self- and proxy-report measures.Among patients with severe injuries, the influence of initial brain injury severity markers on participation seems much stronger than that of social/family environment factors.Children’s and adolescents’ self-reported participation assessed with the Child and Adolescent Scale of Participation may be difficult to interpret.

Academic outcome, participation and health-related quality of life following childhood severe traumatic brain injury: Results of a prospective longitudinal study: The seven-year follow-up of the TGE cohort

Childhood traumatic brain injury (TBI) is the first cause of death and acquired disability and it represents a major public health issue. Childhood severe TBI can lead to motor, cognitive, behavioural and social cognition deficits, which have consequences on academic achievement, social integration, participation and quality of life. Consequences may only appear after a delay, when the skills are supposed to be fully developed. The aim of this study was to prospectively assess academic outcome, health-related quality of life (HRQoL), amount of ongoing care and participation, following childhood severe traumatic brain injury (TBI) over 7–8 years post-injury, in comparison with a matched uninjured control group. Sixty-five children, aged 0–15 years, consecutively admitted in a single trauma center over a 3-year period for severe non-inflicted TBI were included in a prospective longitudinal study. At 7-8 years, they were compared with a matched control group regarding schooling modalities, amount of ongoing care, and standardized questionnaires of HRQoL (PedsQL, including fatigue module), and participation (Child and Adolescent Scale of Participation – CASP). Family socio-economic status (SES) was assessed by parental education level. After a mean delay of 7.7 years, 39 patients participated in the study (60% of the initial sample; 66% boys; mean coma duration: 6.6 days; SD = 4.83; mean age at injury: 7.6 years, SD = 4.72; mean age at assessment: 15.3 years, SD = 4.46, range 7.2–22.2), with no significant differences between participants and non-participants regarding demographic and severity factors, or initial intellectual ability). Only 62% of the TBI group was attending mainstream education (as opposed to 100% of controls). The amount of ongoing rehabilitation was high (35.3% speech-language therapy, 26.4% occupational therapy; 17.6% physiotherapy). Self-reported HRQoL was significantly lower in the TBI than in the control group [71.1; 95% IC 64.8–77.5 versus 83.9; 95% IC 79.3–88.4; P = 0.0026], including the fatigue module [61.1; 95% IC 54.6–67.5 versus 77.4; 95% IC 71.9–82.8; P = 0.0005]. Parent ratings of participation were relatively good but significantly lower than those of controls [86.4; 95% IC 81.4–91.3 versus 96.3; 95% IC 94.6–98.1; P = 0.0002]. Severe childhood TBI leads to severe and long-standing impairments, evident several years post-injury, with consequences on school integration, independence, participation and HRQOL.

Intellectual outcome following childhood severe traumatic brain injury: Results of a prospective longitudinal study: The seven-year follow-up of the TGE cohort

Childhood traumatic brain injury (TBI) is a leading cause of death and lifelong acquired disability. The aim of this study was to prospectively study intellectual ability following childhood severe TBI over 7–8 years post-injury, and factors influencing outcome and change over time. Children (0–15 years) consecutively admitted in a single trauma center for severe non-inflicted TBI over a 3-year period were included in a prospective longitudinal study. Assessment was conducted at 3, 12 and 24 months, and at 7–8 years using age appropriate Wechsler Intelligence Scales. For the 7–8-year follow-up, one third of the group was aged 18 years or more, and a group of matched controls was included. SES was assessed by parents’ education. Sixty-five of the 81 included children survived (66% boys). After a mean delay post-injury of 7.6 years (SD = 1.5), 39 patients (60%) participated in the study [mean age at injury 7.6 years (SD = 4.72; < 6 years, n = 15; ≥ 6 years, n = 23); median initial Glasgow Coma Scale (GCS) score: 6; mean coma duration: 6 days (SD = 4.8)]. Participants and non-participants did not differ in terms of demographic and severity factors, or initial full scale IQ (FSIQ). For 36% of the sample, at least one parent had graduated from high school. At the 7–8 year follow-up, mean FSIQ in the TBI group was significantly lower than in the control group (86.4; SD = 18 versus 97.2; SD = 11.2; P = 0.016), with no significant change over time when compared with initial FSIQ (3 months post-injury; 85.2; SD = 18). In multivariate analysis, FSIQ was predicted mainly by parental SES ( P = 0.031), with a marginal effect of length of coma ( P = 0.079) and no effect of age at injury, initial GCS or intracranial hypertension. Severe childhood TBI leads to severe and long-standing cognitive impairments, without significant improvement over time. Parental education appears to be the main predictor of cognitive outcome several years post-injury, consistent with previous studies in the literature.

Executive function after severe childhood traumatic brain injury – Age-at-injury vulnerability periods: The TGE prospective longitudinal study

BackgroundExecutive 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. MethodsThis 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. ResultsChildren 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. ConclusionsEFs 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.

Predictors of Very-Long-Term Sociocognitive Function after Pediatric Traumatic Brain Injury: Evidence for the Vulnerability of the Immature “Social Brain”

Emotion perception (EP) forms an integral part of social communication and is critical to attain developmentally appropriate goals. This skill, which emerges relatively early in development, is driven by increasing connectivity among regions of a distributed sociocognitive neural network and may be vulnerable to disruption from early-childhood traumatic brain injury (TBI). The present study aimed to evaluate the very-long-term effect of childhood TBI on EP, as well as examine the contribution of injury- and non-injury-related risk and resilience factors to variability in sociocognitive outcomes. Thirty-four young adult survivors of early-childhood TBI (mean [M], 20.62 years; M time since injury, 16.55 years) and 16 typically developing controls matched for age, gender, and socioeconomic status were assessed using tasks that required recognition and interpretation of facial and prosodic emotional cues. Survivors of severe childhood TBI were found to have significantly poorer emotion perception than controls and young adults with mild-to-moderate injuries. Further, poorer emotion perception was associated with reduced volume of the posterior corpus callosum, presence of frontal pathology, lower SES, and a less-intimate family environment. Our findings lend support to the vulnerability of the immature "social brain" network to early disruption and underscore the need for context-sensitive rehabilitation that optimizes early family environments to enhance recovery of EP skills after childhood TBI.

Individual profiles of predictors and their relations to 10 years outcome after childhood traumatic brain injury

Background: Outcome after childhood traumatic brain injury (CTBI) is heterogeneous, with several predictors influencing long-term outcome.Method: This exploratory study used person-oriented cluster analysis to investigate individual profiles of medical, psychological and social predictors and their relation to longitudinal development in a sample of 127 participants with mild, moderate and severe CTBI. Outcome of cognitive, adaptive and academic function was measured at 30 months and 10 years post-injury.Results: A nine-cluster solution, explaining 67% of the variance in the sample, resulted in two clusters with individuals with mostly mild injuries, five with mostly moderate injured individuals and two clusters with severely injured individuals. Best outcome at 10 years post-injury had a cluster with individuals with moderate injuries, young age at injury, average socioeconomic status (SES) and high pre-injury adaptive function. Worst outcome had a small cluster with severely injured individuals, young age at injury, average SES and average pre-injury adaptive function.Conclusions: The findings suggest that pre-injury adaptive function is an influential predictor of outcome following moderate CTBI. Age at injury in the severe group appears to have increased influence over time, with younger age at injury associated with reduced outcome at 10 years after severe CTBI.

Selective Changes in Executive Functioning Ten Years After Severe Childhood Traumatic Brain Injury

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

Community integration following severe childhood traumatic brain injury

Severe childhood traumatic brain injury (TBI) is the leading cause of death and acquired disability in children, causing impairments in children's sensory-motor, cognitive and behavioural functioning, with devastating consequences on community integration. Community integration is the ultimate goal of rehabilitation; it is a complex outcome, with many variables contributing to it. Community integration and quality of life (QOL) are lower in children who sustained severe TBI at a younger age. Further, a wide range of injury-related, demographic and postinjury factors influence outcomes, and should serve as targets for specific interventions. An increasing number of interventions targeting cognitive, behavioural or family-related issues have been developed, with promising results. Children should benefit from early integrated patient and family-centred specific care, and receive long-term follow-up until early adulthood, with regular assessments, enabling detection and treatment of any emerging problem, and to ensure the acquisition of independent living skills and stable vocational outcome when this is possible. So far, few well conducted intervention studies are available, but their number is increasing with positive results on the trained skills. Well designed studies using large samples and looking at generalization of the skills in everyday life are needed.

Implicit and explicit memory outcome in children who have sustained severe traumatic brain injury: Impact of age at injury (preliminary findings)

Primary objective: To examine implicit and explicit memory outcome in children who had sustained severe traumatic brain injury (TBI) through childhood. Opposite patterns of impairments were expected: (i) impaired implicit memory in children with early TBI (TBI-EC, < 6 years) and (ii) impaired explicit memory in children with late TBI (TBI-LC, ≥ 6 years).Research design: Children who had sustained severe TBI more then 1 year ago were assessed.Methods and procedure: Fourteen children who had sustained severe TBI (TBI-EC, n = 10 and TBI-LC, n = 4) between 8 months and 13 years 7 months of age and 13 non-injured control subjects (NC) participated. Implicit (repetition priming and skill learning) and explicit verbal memory were examined.Results: The TBI group performed worse on implicit (repetition priming) and explicit memory tasks compared to the NC group. Moreover, impairments were found in implicit and explicit memory in the TBI-EC, but not in the TBI-LC group.Conclusions: This study has shown, for the first time, that severe childhood TBI may compromise not only explicit, but also implicit memory. Nevertheless, instead of a selective implicit memory impairment, it was found that children who sustained injuries in early childhood present with impairments in both memory systems.
