Abstract

Background: Traumatic brain injury (TBI) is associated with considerable mortality and morbidity in adolescents, but positive outcomes are possible. Resilience is the concept that some individuals flourish despite significant adversity.

Objective: To determine if there is a relationship between resilience-promoting factors that are known to promote resilience and white matter (WM) microstructure 1 year after complicated mild TBI or moderate or severe TBI that is sustained by adolescents.

Method: We examined the relationship between performance on a self-report measure of resilience-promoting factors and WM integrity assessed by diffusion tensor imaging in a group of adolescents who had sustained either a TBI (n = 38) or an orthopedic injury (OI) (n = 23).

Results: Immediately following injury, the individuals with TBI and the OI controls had comparable levels of resilience-promoting factors; however, at 1 year post injury, the TBI group endorsed fewer resilience-promoting factors and exhibited WM disruption compared with the OI controls. The individuals with TBI who had more resilience-promoting factors at 1 year post injury exhibited increased WM integrity, but the OI controls did not. Findings were particularly strong for the following structures: anterior corona radiata, anterior limb of the internal capsule, and genu of the corpus callosum-structures that are implicated in social cognition and are frequently disrupted after TBI. Relationships were notable for caregiver and community-level resilience-promoting factors.

Conclusion: The current findings are some of the first to indicate neurobiological evidence of previously noted buffering effects of resilience-promoting factors in individuals with TBI.

青少年颅脑损伤后弥散张量成像与恢复力的相关性。
背景:创伤性脑损伤(TBI)与青少年的相当大的死亡率和发病率有关,但积极的结果是可能的。韧性是指一些人在重大逆境中仍能茁壮成长的概念。目的:确定已知促进恢复力的恢复力促进因素与青少年并发轻度或中度或重度TBI后1年的白质(WM)微观结构之间是否存在关系。方法:我们研究了一组青少年的自我报告恢复力促进因素的表现与通过扩散张量成像评估的WM完整性之间的关系 = 38)或矫形损伤(OI)(n = 23).结果:受伤后,TBI患者和OI对照组的恢复力促进因子水平相当;然而,在损伤后1年,与OI对照组相比,TBI组支持较少的恢复力促进因素,并表现出WM中断。在损伤后1年具有更多恢复力促进因素的TBI患者表现出WM完整性增加,但OI对照组没有。以下结构的研究结果尤其强烈:前放射冠、内囊前肢和胼胝体膝部结构,这些结构与社会认知有关,在TBI后经常被破坏。人际关系在照顾者和社区层面的恢复力促进因素方面显著。结论:目前的研究结果首次表明了先前注意到的恢复力促进因子对TBI患者的缓冲作用的神经生物学证据。

期刊介绍: Cognitive and Behavioral Neurology (CBN) is a forum for advances in the neurologic understanding and possible treatment of human disorders that affect thinking, learning, memory, communication, and behavior. As an incubator for innovations in these fields, CBN helps transform theory into practice. The journal serves clinical research, patient care, education, and professional advancement. The journal welcomes contributions from neurology, cognitive neuroscience, neuropsychology, neuropsychiatry, and other relevant fields. The editors particularly encourage review articles (including reviews of clinical practice), experimental and observational case reports, instructional articles for interested students and professionals in other fields, and innovative articles that do not fit neatly into any category. Also welcome are therapeutic trials and other experimental and observational studies, brief reports, first-person accounts of neurologic experiences, position papers, hypotheses, opinion papers, commentaries, historical perspectives, and book reviews.
