Étude sur la flexibilité mentale et l’inhibition et leurs relations avec l’autonomie fonctionnelle suite à un traumatisme craniocérébral en âge avancé
Background. The aim of this study was to evaluate executive functions and functional outcomes in elderly patients with traumatic brain injury (TBI) and to explore the effects of demographic and TBI-related variables on these factors. Methods. The sampled population included 53 older adults (≥ 55 years old) divided into two groups: a TBI group (n = 29) and a control group (n = 24). The Trail Making Test (TMT), the Stroop, the Go – No Go and Conflicting instructions subscales from the Frontal Assessment Battery (FAB) along with the Mayo-Portland Adaptability Inventory (MPAI-4) were administrated to both groups. Information about age, education, Glasgow coma score (GCS), length of time post-TBI and lesion location was collected. Results. Differences between healthy participants and individuals with TBI were found in TMT-A, TMT-B, MPAI-4 total score and all subscales scores. Age was associated with TMT -A and TMT-B while education was associated with TMT-A and the ratio score (TMT B/TMT-A). Stroop was associated with length of time post-TBI and occipital lesions. Furthermore, GCS scores were associated with Go – No Go scores. Finally, deficits in TMT-B and frontal lobe lesions were associated with MPAI-4 Abilities Subscale scores. Conclusion. Elderly patients with TBI are slower than control group and show a lower outcome although no executive function deficit was observed. Demographic factors and executive functioning are not associated with functional outcome while age, education, length of time post-TBI influence performances in executive tasks.
