The aim of this preliminary study was to assess the impact of traumatic brain injury (TBI) in older age on executive functioning and on their functional outcome. We also aimed to explore the influence of cognitive reserve (CR) and estimated premorbid cognitive functioning (EPCF) on these components.
A neuropsychological and functional assessment that included tests measuring , and and functional outcome was administered to 29 patients who sustained a mild or moderate TBI in older age and a group of 24 healthy older participants. CR (level of education) and EPCF variables collected in the TBI group were associated with executive function performance and functional outcome.
Patients with TBI obtained significantly worse performances on the spatial working memory (WM) task-reverse condition, and on the completion time of the Trails A and B than the control group. The TBI group also obtained worse functional outcome scores. A higher level of education was associated with better WM performance, and higher estimated premorbid cognitive functioning was associated with better functional outcome post TBI.
Further studies with a larger sample should be conducted to better understand the profile and determinants of recovery from TBI in the elderly.
本初步研究旨在评估老年创伤性脑损伤（TBI）对执行功能及其功能预后的影响。我们还旨在探讨认知储备（CR）和估计的发病前认知功能（EPCF）对这些因素的影响。
对 29 名在老年时发生轻度或中度 TBI 的患者和 24 名健康老年参与者进行神经心理学和功能评估，其中包括测量执行功能的测试，以及功能预后。在 TBI 组中收集的 CR（教育水平）和 EPCF 变量与执行功能表现和功能预后相关。
TBI 组在空间工作记忆（WM）任务反转条件和 Trails A 和 B 的完成时间上的表现明显差于对照组。TBI 组的功能预后评分也较差。较高的教育水平与更好的 WM 表现相关，而较高的发病前认知功能估计与 TBI 后更好的功能预后相关。
应进行更多的研究，以更好地了解老年人 TBI 恢复的特征和决定因素。
