Executive functions, prospective memory and metacognition in children with traumatic brain injury : assessment, characterization and rehabilitation

Abstract : Part one of this PhD explored executive functions (EF) and related impairments after childhood severe TBI. Executive dysfunction was worse when the injury occurred during the period of rapid development of EF. Paper and pencil tasks underestimated EF impairment in daily life. Impairment in prospective memory persisted at seven years post injury, and into adulthood. A model of child anosognosia, and directions for cognitive rehabilitation interventions, are proposed based on a study of self-awareness after childhood TBI. Part two of this PhD investigated methods of remediating EF dysfunction. A systematic review found that Goal Management Training (GMT) is effective in adults when coupled with personal goal setting, external cueing, personalised homework to increase patients' commitment and training intensity and daily life training activities. Based on this literature review, a paediatric GMT intervention was adapted and tested. The intervention showed limited effectiveness, with inconsistency across outcome measures. Children did not apply the metacognitive strategies taught during the training. Furthermore, there was no evidence of generalisation of task-specific improvements to a novel, parallel version of the secondary outcome measure (the Children’s Cooking Task). The adapted GMT did not seem developmentally coherent for younger children. It is clear that deficits in EF arising from TBI continue to be an important target for rehabilitation interventions in children. Proposals on how the use of novel innovative outcome measures and methodologies may improve the field of EF rehabilitation in children with TBI are presented.
