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.
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.
