Évaluation des compétences mnésiques 3, 12 et 24 mois après un traumatisme crânien sévère de l’enfant : résultats du suivi de la cohorte TGE (Traumatisme Crânien Grave de l’Enfant)

Abstract : Background and aims: few longitudinal investigations explored memory functions after severe childhood Traumatic Brain Injury (TBI). The aims of this study were: (1) to prospectively measure memory functioning following severe childhood 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 functions and other TBI outcomes. Methods: Children (aged 0–15 years; n=65) consecutively admitted in a single trauma center, who survived after severe non-inflicted TBI (Glasgow Coma Scale score ≤8) over a 3-year period, were included in a prospective longitudinal study (TGE cohort). Memory function was assessed in 46 children aged 5-15 years, using the Children’s Memory Scale (CMS) at 3, 12, and 24 months post-injury. Results: mean general memory score was low at 3 months (m=89, SD=20.5) but in the normal range at 12 and 24 months (m=99, SD=22.7 and m=104, SD=25.6, respectively), however scores were extremely variable. Improvement from 3 to 24 months varied according to the memory index, with strong improvement of immediate visual memory, but low for attention/concentration. Lower general memory score was associated at each time point with higher injury severity, lower intellectual ability and functional status, and higher overall disability; and at 12 months post-injury, with type of ongoing education. Conclusion: memory functioning is highly variable after severe childhood TBI, related to injury severity and functional, cognitive and educational outcomes; improvement is significant during the first- year post-injury, but variable according to the type of memory assessed.
