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

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.

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

PURPOSE: 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. METHODS: Self- (n = 34) and/or parent-reports (n = 25) of HRQoL were collected for 38 participants (age 7-22 years) 7 years 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). RESULTS: 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. CONCLUSIONS: 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.

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

OBJECTIVE: 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). METHODS: 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. RESULTS: 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. CONCLUSION: 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).

Assessment of everyday executive functioning using the BRIEF in children and adolescents treated for brain tumor.

Objective: Childhood brain tumors (BTs) and their treatment often negatively affect development of executive functions. Previous studies have reported executive functions deficits, particularly through questionnaires of daily life. This study aimed to assess executive functioning in everyday life following pediatric BT, in a larger and more histologically diverse sample than previously, and to study clinical and demographic factors influencing outcome.Methods: Assessment of executive functioning using parent ratings of the Behavior Rating Inventory of Executive Function (BRIEF), in a large sample of children treated for various BT (n = 153). Clinical and demographic factors were: age at diagnostic, age at assessment, parental education level, radiation therapy.Results: Significant difficulties were found in the 3 composite indices and in the majority of the BRIEF subscales. The highest level of difficulties was observed in the Working Memory subscale. Older age at assessment and younger age at diagnosis were significantly associated with higher levels of parent-reported difficulties, particularly for metacognition.Conclusions: Parents of children treated for BT report widespread and persistent deficits in executive functions that negatively affect their everyday functioning. Including analysis of all clinical scales and composite indices allows a more comprehensive approach and enables to specify the patients' executive profile.

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

The 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.

Maternal stress and pediatric brain cancer: A French study.

BACKGROUND: Despite evidence that pediatric cancer induces a trajectory of parental stress, studies including mothers of children with malignant brain tumors remain scarce. The present work aims to add to the scientific literature by evaluating maternal stress with a French translation of the Pediatric Inventory for Parents (PIP) in a population of mothers whose children have been diagnosed with a brain tumor. PROCEDURE: The mothers of 35 children with malignant brain tumors completed the Pediatric Inventory for Parents (PIP), the State-Trait Anxiety Inventory (STAI) and the Family Assessment Device (FAD) at a mean time since diagnosis of 2.3 years. RESULTS: The PIP showed good internal consistency and correlated significantly with the STAI and the FAD. Maternal stress scores were higher in younger mothers and in mothers of younger children. Emotional functioning was the most affected domain. CONCLUSIONS: Emotional stress as assessed by the PIP in mothers of children with malignant brain tumors is considerable, and should be routinely assessed, in order to implement appropriate specific psychosocial interventions when needed.

Parental stress and paediatric acquired brain injury.

OBJECTIVE: Studies on parental stress following childhood acquired brain injury (ABI-including brain tumours (BT) and other brain injuries) are scarce. The aim of this study was to assess maternal stress in a sample of children and adolescents diagnosed with severe paediatric ABI. METHODS: Seventy-eight French-speaking mothers of 37 with BT and 41 with other ABIs completed the Paediatric Inventory for Parents (PIP), the State-Trait Anxiety Inventory (STAI) and the Family Assessment Device (FAD) at a mean time since diagnosis of 1.5 years. RESULTS: The PIP correlated significantly with the STAI and the FAD. Socio-demographic factors, such as the age of mother and child, and the mother's educational level, were correlated with both maternal stress and anxiety. Maternal stress scores were comparable between groups. Emotional functioning was the most markedly affected domain, followed by parental role. CONCLUSIONS: Emotional stress as assessed by the PIP in mothers of children with ABI is significant and should motivate specific psychosocial interventions.

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

PURPOSE/OBJECTIVE: 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. METHOD/DESIGN: 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. RESULTS: 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. CONCLUSIONS/IMPLICATIONS: These results highlight the importance of long-term follow-up and individualized behavioral interventions for children who sustained severe TBI.

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

BACKGROUND: Childhood severe traumatic brain injury (TBI) is a leading cause of long-lasting acquired disability, but predicting long-term functional outcome remains difficult. OBJECTIVES: 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. METHODS: 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. RESULTS: 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%). CONCLUSIONS: 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.

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.

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

OBJECTIVE: To explore memory functioning 7 years after severe paediatric traumatic brain injury (TBI), associated factors, and relationships with other outcomes. METHOD: 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. RESULTS: 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. CONCLUSIONS: 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.

Associations of language-based bedtime routines with early cognitive skills and academic achievement: A follow-up from kindergarten to middle school.

OBJECTIVE: This study aimed to investigate the extent to which language-based bedtime routines (LBR) reported by parents before kindergarten were associated with early cognitive skills at kindergarten and subsequent academic achievement in typically developing children. METHOD: We followed a community-based sample of 664 French-speaking adolescents from kindergarten (5-6 years) to the end of middle school (15 years). Kindergarten measures included a parental questionnaire aimed at assessing the presence or absence of any kind of LBR, such as storytelling, looking at children's books, reading a story, listening to songs, or singing nursery rhymes, as well as family contextual characteristics. Children also performed standardized assessments of oral language, pre-reading skills, and non-verbal reasoning. In middle school, children sat a national diploma typically used as an indicator of general academic achievement in Grade 9. RESULTS: After adjusting for family characteristics, the presence of language-based bedtime routines (57%) predicted cognitive-academic skills in kindergarten, and was positively associated with academic achievement at Grade 9, related to the beneficial effect on children's vocabulary in kindergarten. CONCLUSION: The presence of language-based bedtime routines may provide an indicator of positive parental behaviour including exposure to literacy activities, contributing to children's early cognitive development and subsequent academic achievement.

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

BACKGROUND: Childhood severe traumatic brain injury (TBI) is a leading cause of long-lasting acquired disability, but little is known about functional outcome. OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

The role of cerebellum in the child neuropsychological functioning.

This chapter proposes a review of neuropsychologic and behavior findings in pediatric pathologies of the cerebellum, including cerebellar malformations, pediatric ataxias, cerebellar tumors, and other acquired cerebellar injuries during childhood. The chapter also contains reviews of the cerebellar mutism/posterior fossa syndrome, reported cognitive associations with the development of the cerebellum in typically developing children and subjects born preterm, and the role of the cerebellum in neurodevelopmental disorders such as autism spectrum disorders and developmental dyslexia. Cognitive findings in pediatric cerebellar disorders are considered in the context of known cerebellocerebral connections, internal cellular organization of the cerebellum, the idea of a universal cerebellar transform and computational internal models, and the role of the cerebellum in specific cognitive and motor functions, such as working memory, language, timing, or control of eye movements. The chapter closes with a discussion of the strengths and weaknesses of the cognitive affective syndrome as it has been described in children and some conclusions and perspectives.

Pediatric traumatic brain injury and abusive head trauma.

Childhood traumatic brain injury (TBI) commonly occurs during brain development and can have direct, immediately observable neurologic, cognitive, and behavioral consequences. However, it can also disrupt subsequent brain development, and long-term outcomes are a combination of preinjury development and abilities, consequences of brain injury, as well as delayed impaired development of skills that were immature at the time of injury. There is a growing number of studies on mild TBI/sport-related concussions, describing initial symptoms and their evolution over time and providing guidelines for effective management of symptoms and return to activity/school/sports. Mild TBI usually does not lead to long-term cognitive or academic consequences, despite reports of behavioral/psychologic issues postinjury. Regarding moderate to severe TBI, injury to the brain is more severe, with evidence of a number of detrimental consequences in various domains. Patients can display neurologic impairments (e.g., motor deficits, signs of cerebellar disorder, posttraumatic epilepsy), medical problems (e.g., endocrine pituitary deficits, sleep-wake abnormalities), or sensory deficits (e.g., visual, olfactory deficits). The most commonly reported deficits are in the cognitive-behavioral field, which tend to be significantly disabling in the long-term, impacting the development of autonomy, socialization and academic achievement, participation, quality of life, and later, independence and ability to enter the workforce (e.g., intellectual deficits, slow processing speed, attention, memory, executive functions deficits, impulsivity, intolerance to frustration). A number of factors influence outcomes following pediatric TBI, including preinjury stage of development and abilities, brain injury severity, age at injury (with younger age at injury most often associated with worse outcomes), and a number of family/environment factors (e.g., parental education and occupation, family functioning, parenting style, warmth and responsiveness, access to rehabilitation and care). Interventions should identify and target these specific factors, given their major role in postinjury outcomes. Abusive head trauma (AHT) occurs in very young children (most often <6 months) and is a form of severe TBI, usually associated with delay before appropriate care is sought. Outcomes are systematically worse following AHT than following accidental TBI, even when controlling for age at injury and injury severity. Children with moderate to severe TBI and AHT usually require specific, coordinated, multidisciplinary, and long-term rehabilitation interventions and school adaptations, until transition to adult services. Interventions should be patient- and family-centered, focusing on specific goals, comprising education about TBI, and promoting optimal parenting, communication, and collaborative problem-solving.

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.

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

OBJECTIVES: 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 7 years after severe childhood TBI in comparison with a matched control group and to investigate associated factors. METHODS: 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 65 survivors) 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. RESULTS: 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). CONCLUSIONS: Executive and attention deficits were evident 7 years 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.

Language and cognitive outcomes after childhood stroke: Theoretical implications for hemispheric specialization.

The purpose of this study was to investigate language and cognitive outcomes following severe childhood stroke, and the role of age at stroke according to lesion lateralization. We retrospectively included children consecutively admitted to a physical medicine and rehabilitation department between 1992 and 2015 following childhood stroke (age at stroke 1 month to15 years). Data collection included demographic and clinical information, results of cognitive assessments on the Wechsler Intelligence scales, detailed language assessments by speech and language therapists, and long-term academic outcome. Overall, 184 children (52% boys; mean age at assessment = 8.5 years, range .7-15.4 years) were hospitalized following ischemic (n = 79) or hemorrhagic (n = 105) stroke. After a median time since stroke of 4 months (n = 135), mean Full-Scale, Verbal, and Performance Intellectual Quotient (FSIQ, VIQ and PIQ) were 85 (SD = 19), 93 (SD = 22), and 85 (SD = 20), respectively. In language tests (n = 130) assessing lexical and syntactic expression and comprehension, 26%-53% of the children exhibited impairments (scores <2SD). After a median follow-up of 40 months, only 27% of the children were following a normal curriculum without adaptations or delay, and 27% were attending special education programs. School situation was strongly associated with language and FSIQ scores. Language and verbal IQ scores were significantly lower (p < .01) among patients with lesions in the left hemisphere as opposed to the right. After a left hemisphere lesion, language skills were not associated with age at stroke, but for right hemisphere lesions, language was more impaired among children who were younger at stroke onset. PIQ tended to correlate positively with age at stroke in left hemisphere lesions (poorer PIQ in early lesions) and negatively for right hemisphere lesions (poorer PIQ in late lesions). These findings, discussed in the light of the brain vulnerability and plasticity hypotheses, are in favor of a developmental view of hemispheric specialization.

Time knowledge difficulties following treatment for malignant cerebellar tumors.

In children treated for malignant cerebellar tumors, there are only a few studies investigating temporal skills, despite the role of the cerebellum in time processing being generally acknowledged. Children's time knowledge has been defined as the correct representation and use of familiar time units. The present study compares time knowledge in 38 children treated for malignant cerebellar tumors (mean age 11.6 years) with 105 typically-developing (TD) children. The performances on all time knowledge subtests were significantly lower in the tumor group. The results also confirm a lower mean IQ in the children treated for cerebellar tumors, related to slower processing speed and poorer performance on working memory and non-verbal tasks. However, the lower IQ does not explain the considerable difficulties in the acquisition of time knowledge. These results are discussed in the light of the role of the cerebellum in time processing and in the context of two different models of temporal processing: the internal clock model and the neural network state model.

Core deficits and quality of survival after childhood medulloblastoma: a review.

BACKGROUND: Medulloblastoma is the most common malignant central nervous system tumor in children. Treatment most often includes surgical resection, craniospinal irradiation, and adjuvant chemotherapy. Although survival has improved dramatically, the tumor and its treatments have devastating long-term side effects that negatively impact quality of survival (QoS). The objective was to review the literature on QoS following childhood medulloblastoma. METHODS: This narrative review is based on a Medline database search and examination of the reference lists of papers selected. RESULTS: Frequent problems after medulloblastoma treatment include medical complications, such as long-term neurological and sensory (hearing loss) impairments; endocrine deficits, including growth problems; and secondary tumors. Neurocognitive impairment is repeatedly reported, with decreasing cognitive performances over time. Although all cognitive domains may be affected, low processing speed, attention difficulties, and working memory difficulties are described as the core cognitive deficits resulting from both cerebellar damage and the negative effect of radiation on white matter development. Long-term psychosocial limitations include low academic achievement, unemployment, and poor community integration with social isolation. Important negative prognostic factors include young age at diagnosis, conventional craniospinal radiotherapy, presence of postoperative cerebellar mutism, and perioperative complications. The influence of environmental factors, such as family background and interventions, remains understudied. CONCLUSION: Future studies should focus on the respective impact of radiation, cerebellar damage, genomic and molecular subgroup parameters, and environmental factors on cognitive and psychosocial outcomes. Long-term (probably lifelong) follow-up into adulthood is required in order to monitor development and implement timely, suitable, multi-disciplinary rehabilitation interventions and special education or support when necessary.
