Cognitive function and participation in children and youth with mild traumatic brain injury two years after injury.

BACKGROUND: 10-20% of children and youth with mild traumatic brain injury (mTBI) suffer from long-term cognitive impairments with, supposedly, a negative impact on most domains of functioning. OBJECTIVES: To describe cognitive functioning and participation in children and youth two-years post-mTBI and to determine associated risk factors. METHODS: Cross-sectional study among 73 patients (aged 6-22 years), hospital diagnosed with mTBI. Linear regression modelling was used to investigate the effect of potential predictors on cognitive functioning as measured with a neuropsychological assessment (NPA), two-years post-injury. Extent of participation was assessed using the Child and Adolescent Scale of Participation and correlation analysis was conducted to examine its association with level of cognitive functioning. RESULTS: 7-15% of all participants had impaired cognitive functions, especially in the domains of processing speed, inhibitory control, cognitive flexibility, visuospatial constructional ability and visuospatial memory. Lower level of education and pre-injury cognitive problems were predictive for a lower level of long-term cognitive functioning. Slower inhibition speed, impaired visuospatial and verbal working memory were associated with reduced participation. DISCUSSION AND CONCLUSIONS: Persisting cognitive problems two years after mTBI were mostly related to the lower level of education and to pre-injury cognitive problems. Although participation of the patients was reported by parents to be relatively high, slower inhibition speed, impaired visuospatial and verbal working memory were associated with reduced participation.

Gaming supports youth with acquired brain injury? A pilot study.

AIM: To explore the effects of usage of the Nintendo Wii on physical, cognitive and social functioning in patients with acquired brain injury (ABI). METHODS: This multi-centre, observational proof-of-concept study included children, adolescents and young adults with ABI aged 6-29 years. A standardized, yet individually tailored 12-week intervention with the Nintendo Wii was delivered by trained instructors. The treatment goals were set on an individual basis and included targets regarding physical, mental and/or social functioning. Outcome assessments were done at baseline and after 12 weeks and included: the average number of minutes per week of recreational physical activity; the CAPE (Children's Assessment of Participation and Enjoyment); the ANT (Amsterdam Neuropsychological Tasks); the achievement of individual treatment goals (Goal Attainment Scaling); and quality-of-life (PedsQL; Pediatric Quality of Life Inventory). Statistical analyses included paired t-tests or Wilcoxon-Signed-Rank tests. RESULTS: Fifty patients were included (31 boys and 19 girls; mean age 17.1 years (SD = 4.4)), of whom 45 (90%) completed the study. Significant changes of the amount of physical activity, speed of information processing, attention, response inhibition and visual-motor coordination (p < 0.05) were seen after 12 weeks, whereas there were no differences in CAPE or PedsQL scores. Two-thirds of the patients reported an improvement of the main treatment goal. CONCLUSION: This study supports the potential benefits of gaming in children and youth with ABI.
