Meta Analyses

Early retrospective studies suggested that individuals with a history of a traumatic brain injury (TBI) had a higher risk for dementia than those without a history of TBI. Two meta-analyses demonstrated that the risk for dementia is higher among men, but not women, with a history of TBI. More recent prospective studies, however, are providing discrepant findings, probably due to important methodological differences. TBI is usually associated with significant neuropsychological deficits, primarily in the domains of attention, executive functioning and memory. These deficits may not improve with time. TBI may also lower the threshold for the clinical expression of dementia among predisposed individuals, and the onset of Alzheimer's disease (AD)-like neuropathological and biochemical changes immediately after severe TBI may play an important role in this mechanism.

Abstract INTRODUCTION Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in the US. The effects of TBI on quality of life may not become apparent for years after the injury. There are conflicting reports in the literature regarding long term outcomes. Physicians are often asked to predict long term functional and cognitive outcomes, with limited data available. METHODS Patients with severe TBI (GCS = 9) who previously participated in a clinical trial during the 1980s were followed up with and compared to healthy controls without history of TBI. A health questionnaire, sports concussion assessment tool version 3 (SCAT3) and the Telephone Interview for Cognitive Status-modified (TICS-m) were completed over the phone and compared with controls using t-test. GCS at admission and 12-month GRS were used to predict to TICS-M at 30 years using linear regression. RESULTS >45 of the initial 168 subjects were confirmed alive, and 37 (13 females; mean age: 52.43 years S.D. 10.7) consented. Controls (n = 58; 23 females; mean age = 54 years, S.D. 11.5) had lower symptom severity score (6.7 S.D. 12.6 versus 20.6 S.D. 25.3; P = 0.005), lower total number of symptoms (3.4 S.D. 4.7 versus 7.12 S.D. 6.5; P = 0.006), higher standardized assessment of concussion score (25.6 S.D. 2.8 versus 21.2 S.D. 6.9; P = 0.001), and lower corrected MPAI-4 (22.3 S.D. 17.0 versus 43.7 S.D. 12.8; P < 0.001). GCS at admission did not predict cognitive status at 30-years assessed using TICS-M (P = 0.345). The Glasgow Outcome Scale score at 12-months was correlated to TICS-M at 30 years (R = 0.548, P < 0.001); each point decrease in GOS decreasing the score at TICS-M by 5.6 points. CONCLUSION Remote history of TBI disrupts the lives of survivors long after injury. Admission GCS does not predict cognitive status 30 years after TBI. The GOS at 12-months predicted the cognitive status assessed using TICS-M score at 30 years.

Abstract Objective Recovery following traumatic brain injury (TBI) is complex. Often following mild TBI, recovery occurs within days or weeks, though this is not always the case. Following more severe TBI, some recover quickly, while many never fully recover. This study examines acute predictors of chronic neurobehavioral symptoms in U.S. military service members (Age: M = 33.9 years, SD = 10.2) without injury (n = 86), or with history of uncomplicated mild traumatic brain injury (TBI; n = 56), complicated mild, moderate, or severe TBI (mod-sev TBI; n = 43), or bodily injury (n = 25). Method Participants completed the Neurobehavioral Symptom Inventory (NSI), Posttraumatic Stress Disorder Checklist, Alcohol Use Disorder Checklist, Combat Exposure Scale, and TBI Quality of Life and passed symptom validity tests at 0–8 months and ≥ 2 years post-injury. Forward stepwise logistic regression included 26 potential predictors (demographics, injury characteristics, military characteristics, and self-report measures at baseline) of International Statistical Classification of Diseases and Related Health Problems-10 Postconcussional Syndrome (PCSy) at follow-up. Results Cognitive Concerns (Exp(B) = .896, p = .001), Sleep (Exp(B) = 1.874, p &lt; .001), Somatosensory Symptoms (Exp(B) = 1.194, p = .012), and mod-sev TBI (Exp(B) = 2.959, p = .045) significantly predicted follow-up PCSy. When baseline NSI symptoms were removed from the model, Cognitive Concerns (Exp(B) = .902, p &lt; .001), Post-traumatic stress (Exp(B) = 1.173, p = .001), and Resilience (Exp(B) = .950, p &lt; .031) significantly predicted PCSy. For all included measures in both models, higher symptoms at baseline predicted increased likelihood of follow-up PCSy. Both models correctly classified 81.3% of participants. Conclusion Findings suggest patients reporting psychological distress and cognitive concerns acutely should be targeted for treatment to mitigate prolonged neurobehavioral symptoms.

AbstractObjectives:This study examined the relationship of the home environment to long-term executive functioning (EF) following early childhood traumatic brain injury (TBI).Methods:Participants (N=134) were drawn from a larger parent study of 3- to 6-year-old children hospitalized for severe TBI (n=16), complicated mild/moderate TBI (n=44), or orthopedic injury (OI;n=74), recruited prospectively at four tertiary care hospitals in the United States and followed for an average of 6.8 years post-injury. Quality of the home environment, caregiver psychological distress, and general family functioning were assessed shortly after injury (i.e., early home) and again at follow-up (i.e., late home). Participants completed several performance-based measures of EF at follow-up. Hierarchical regression analyses examined the early and late home environment measures as predictors of EF, both as main effects and as moderators of group differences.Results:The early and late home environment were inconsistent predictors of long-term EF across groups. Group differences in EF were significant for only the TEA-Ch Walk/Don’t Walk subtest, with poorer performance in the severe TBI group. However, several significant interactions suggested that the home environment moderated group differences in EF, particularly after complicated mild/moderate TBI.Conclusions:The home environment is not a consistent predictor of long-term EF in children with early TBI and OI, but may moderate the effects of TBI on EF. The findings suggest that interventions designed to improve the quality of stimulation in children’s home environments might reduce the long-term effects of early childhood TBI on EF.

Abstract Objective: This qualitative study aimed to identify the service and support needs of people with a recent history of traumatic brain injury (TBI) living in the community. Methods: A postal survey was sent to 662 people 6–18 months after hospital admission for a mild-to-severe TBI. The survey included an open-ended item (‘wish-basket’) for collecting ideas about important unmet needs. Results: Responses from 53 individuals were coded and processed using thematic analysis. Five themes (n = 39) were identified, three of which were related to personal needs. These personal wishes were about being symptom-free, independent and emotionally supported by, and connected to, loved ones. The remaining themes were about the wished-for changes to the health system and society, such as wishing for health care continuity (as opposed to being abandoned), and for greater understanding and support by society. Conclusions: There is scope to improve the services and support for people living with TBI in the community. This includes reconsidering the way that discharge occurs, addressing the personal needs that remain when living in the community and promoting greater social awareness of TBI to counteract disadvantage.

AbstractBackgroundTraumatic brain injury (TBI) occurs frequently during child and early adulthood, and is associated with negative outcomes including increased risk of drug abuse, mental health disorders and criminal offending. Identification of previous TBI for at-risk populations in clinical settings often relies on self-report, despite little information regarding self-report accuracy. This study examines the accuracy of adult self-report of hospitalized TBI events and the factors that enhance recall.MethodsThe Christchurch Health and Development Study is a birth cohort of 1265 children born in Christchurch, New Zealand, in 1977. A history of TBI events was prospectively gathered at each follow-up (yearly intervals 0–16, 18, 21, 25 years) using parental/self-report, verified using hospital records.ResultsAt 25 years, 1003 cohort members were available, with 59/101 of all hospitalized TBI events being recalled. Recall varied depending on the age at injury and injury severity, with 10/11 of moderate/severe TBI being recalled. Logistic regression analysis indicated that a model using recorded loss of consciousness, age at injury, and injury severity, could accurately classify whether or not TBI would be reported in over 74% of cases.ConclusionsThis research demonstrates that, even when individuals are carefully cued, many instances of TBI will not recalled in adulthood despite the injury having required a period of hospitalization. Therefore, screening for TBI may require a combination of self-report and review of hospital files to ensure that all cases are identified. (JINS, 2016, 22, 717–723)

ObjectiveTo determine the prevalence of lifetime history of traumatic brain injury (TBI) with loss of consciousness (LOC) among adult, non-institutionalised residents of Ohio.MethodsWe analysed data from 2014 Ohio Behavioral Risk Factor Surveillance System, which included a state-specific module designed to elicit lifetime history of TBI.ResultsOf non-institutionalised adults 18 years and over living in Ohio, 21.7% reported at least one lifetime TBI with LOC, 2.6% experienced at least one moderate or severe such injury, 9.1% experienced a TBI with LOC before age 15 years and 10.8% experienced either TBI with LOC before age 15 years or a moderate or severe injury. Males, those with lower incomes and those unable to work were more likely to have incurred at least one TBI with LOC, multiple TBIs with LOC, a moderate or severe TBI and a TBI with LOC before age15.ConclusionsOne in five adults experienced TBIs of sufficient severity to cause LOC; 3% experienced at least one moderate or severe TBI and almost 10% experienced a first TBI with LOC before the age of 15 years. The prevalence of lifetime TBI in the present study suggests that there may be a substantially greater burden of injury than concluded from previous prevalence estimates.

Cox Proportional Hazard Regression

Whether traumatic brain injury (TBI) is causally related to substance related disorder (SRD) is still debatable, especially in persons with no history of mental disorders at the time of injury. This study analyzed data in the Taiwan National Health Insurance Research Database for 19,109 patients aged ≥18 years who had been diagnosed with TBI during 2000–2010. An additional 19,109 randomly selected age and gender matched patients without TBI (1 : 1 ratio) were enrolled in the control group. The relationship between TBI and SRD was estimated with Cox proportional hazard regression models. During the follow-up period, SRD developed in 340 patients in the TBI group and in 118 patients in the control group. After controlling for covariates, the overall incidence of SRD was 3.62-fold higher in the TBI group compared to the control group. Additionally, patients in the severe TBI subgroup were 9.01 times more likely to have SRD compared to controls. Notably, patients in the TBI group were prone to alcohol related disorders. The data in this study indicate that TBI is significantly associated with the subsequent risk of SRD. Physicians treating patients with TBI should be alert to this association to prevent the occurrence of adverse events.

AbstractThis study investigated the effect of severe traumatic brain injury (TBI) on prospective memory. It also sought to identify the relative contributions of executive functioning and retrospective memory to prospective memory. Thirteen patients with severe TBI and 13 matched control subjects were assessed on two novel, yet ecologically valid, experimental measures of prospective memory and standard tests of neuropsychological functioning. Participants with TBI performed significantly worse than did controls on neuropsychological tests and a time-based prospective memory task, indicating that TBI affected not only retrospective but also prospective memory functioning. Multiple regression analyses identified relationships between executive functioning and time-based prospective memory and between retrospective memory and event-based prospective memory. Implications of these findings for the assessment and rehabilitation of memory impairment in individuals with TBI are discussed.

Abstract Objective Despite the strong evidence suggesting post-traumatic stress disorder (PTSD) symptoms negatively impact cognition following mild traumatic brain injury (TBI), little is known about this relationship in more severe TBI. This study investigates the relationship between PTSD symptoms and cognitive performance following complicated mild, moderate, severe, and penetrating TBI. Methods Participants were 137 U.S. military service members and veterans (SMVs) with a history of complicated mild or more severe TBI prospectively enrolled in the Defense and Veterans Brain Injury Center (DVBIC)/Traumatic Brain Injury Center of Excellence (TBICoE) 15-Year Longitudinal TBI Study. Participants were divided into two groups: complicated mild/moderate TBI (n = 64) and severe/penetrating TBI (n = 73). Participants completed a neuropsychological assessment, including the PTSD Checklist-Civilian Version one year or more post-injury. Six neuropsychological composite scores and an overall test battery mean (OTBM) were considered. Participants who failed symptom validity tests were excluded. Hierarchical linear regressions were conducted evaluating neuropsychological performance. Results TBI severity (βs:-0.163 to −0.253, ps &lt; 0.04) and PTSD symptoms (βs:-0.189 to −0.212), ps &lt; 0.03) were related to neuropsychological performance in the overall sample. Within the severe/penetrating TBI group, PTSD symptoms were unrelated to cognitive performance. Within the complicated mild/moderate TBI group, PTSD symptoms were significantly related to processing speed (R2Δ = 0.080, β = −0.284, p = 0.016), immediate memory (R2Δ = 0.204, β = −0.453, p &lt; 0.001), delayed memory (R2Δ = 0.180, β = −0.426, p &lt; 0.001), executive functioning (R2Δ = 0.102, β = −0.319, p = 0.007), and the OTBM (R2Δ = 0.170, β = −0.413, p &lt; 0.001). Discussion PTSD symptom severity was significantly related to neuropsychological performance in SMVs with complicated mild/moderate TBI. PTSD symptoms should be considered when evaluating patients with a history of complicated mild to moderate TBI.
