Early Bifrontal Brain Injury: Disturbances in Cognitive Function Development

Abstract

We describe six psychomotor, language, and neuropsychological sequential developmental evaluations in a boy who sustained a severe bifrontal traumatic brain injury (TBI) at 19 months of age. Visuospatial, drawing, and writing skills failed to develop normally. Gradually increasing difficulties were noted in language leading to reading and spontaneous speech difficulties. The last two evaluations showed executive deficits in inhibition, flexibility, and working memory. Those executive abnormalities seemed to be involved in the other impairments. In conclusion, early frontal brain injury disorganizes the development of cognitive functions, and interactions exist between executive function and other cognitive functions during development.

Assessment of executive functioning in children and young adults treated for frontal lobe tumours using ecologically valid tests

“…These results are consistent with the two case studies of children with frontal lobe tumours (Anderson et al, 2000;Daigneault et al, 1997) who had planning deficits in the Tower of Hanoi Test (Daigneault et al, 1997) and the copy of the Rey Figure (Anderson et al, 2000). Planning deficits have also been reported in most case reports of childhood focal frontal lobe lesion, using a number of tests (Anderson et al, 2000;Bonnier et al, 2010;Williams & Mateer, 1992), as well as in group studies following TBI Mataro et al, 2010), and in an ecological way (Chevignard et al, 2009). Ecological measurement of planning using the BRIEF questionnaire also confirmed the planning deficits, with one-half of the children scoring in the clinical range in the home environment and two-thirds in the school environment.…”

Development of executive functions in Lebanese children

“…D'un autre côté, les troubles cognitifs généralement décrits sont des difficultés de planification, de flexibilité mentale, d'inhibition, de MDT, de résolution de problème et d'attention qui affectent, à leur tour, l'ensemble des fonctions cognitives Anderson et al, 2000). Une atteinte préférentielle de certaines FE cognitives malgré la préservation d'autres semble également possible (Anderson et al, 2000 ;Bonnier et al, 2010). De plus, les troubles cognitifs et comportementaux décrits après des lésions frontales chez les enfants sont souvent durables (Chen et al, 2013).…”
