Comprehensive assessment of executive functioning following childhood severe traumatic brain injury: clinical utility of the child executive functions battery.

Objectives: To perform a detailed description of executive functioning following moderate-to-severe childhood traumatic brain injury (TBI), and to study demographic and severity factors influencing outcome. Methods: A convenience sample of children/adolescents aged 7-16 years, referred to a rehabilitation department after a TBI (n = 43), was compared to normative data using a newly developed neuropsychological test battery (Child Executive Functions Battery-CEF-B) and the BRIEF. Results: Performance in the TBI group was significantly impaired in most of the CEF-B subtests, with moderate to large effect sizes. Regarding everyday life, patients were significantly impaired in most BRIEF clinical scales, either in parent or in teacher reports. Univariate correlations in the TBI group did not yield significant correlations between the CEF-B and socio-economic status, TBI severity, age at injury, or time since injury. Conclusion: Executive functioning is severely altered following moderate-to-severe childhood TBI and is best assessed using a combination of developmentally appropriate neuropsychological tests and behavioral ratings to provide a comprehensive understanding of children's executive functions.

Ecological Assessment of Everyday Executive Functioning at Home and at School Following Childhood Traumatic Brain Injury Using the BRIEF Questionnaire.

OBJECTIVES: To describe dysexecutive symptoms in children with traumatic brain injury (TBI) using the Behavior Rating Inventory of Executive Function (BRIEF); to compare parent- and teacher-ratings, to analyze the differential impairment in the BRIEF subscales, and factors influencing outcome. PARTICIPANTS: Children aged 5 to 18 years 11 months, referred to a rehabilitation department following TBI. OUTCOME MEASURES: Parent- and teacher reports of the BRIEF. RESULTS: A total of 194 patients participated in the study: mild (n = 13), moderate (n = 12), severe (n = 169); mean 4.92 (standard deviation = 3.94) years post-injury. According to parent ratings (n = 193), all BRIEF subscales and indices were significantly elevated (23.8%-48% in the clinical range). The Working Memory subscale score was significantly higher than all other subscales. Results of teacher ratings (n = 28) indicated similar significantly elevated scores in all subscales (39.3%-57.2% in the clinical range). No significant difference was found between parent and teacher ratings, which were significantly correlated. Regression analyses indicated that, in children with severe TBI, parental BRIEF overall and metacognition indices were significantly predicted by younger age at injury and older age at assessment, whereas no significant predictor of behavioral regulation index was identified. DISCUSSION AND CONCLUSION: This study highlights significant executive dysfunction in everyday life several years after childhood TBI, evident in home and school environments.

Remediation of learning difficulties in children after treatment for a cerebellar medulloblastoma: a single-case study.

In the process of establishing a methodology for individualized remediation programmes in children treated for cerebellar tumour, this study followed prospectively over 11 years a young child treated for a medulloblastoma at 18 months of age throughout the rehabilitation process. Repeated neuropsychological and academic evaluations evidenced temporary disruptive behaviour, deficient manual and visual abilities, attention and working memory difficulties, but preserved language abilities, in relation with vermian and left cerebellar damage. However, the described remediation programmes and interventions allowed the child to have fluent progression in school. Limits and benefits of rehabilitation are discussed.
