Abstract Objective Traumatic brain injury (TBI) survivors exhibit cognitive deficits. Language factors can also influence neurocognitive performance. We examined the effects of TBI and bilingualism/monolingualism on a test of attention and cognitive speed (i.e., Symbol Digit Modalities Test; SDMT). Method The sample (N = 98) consisted of 37 controls (19 bilingual; 18 monolingual), 34 acute TBI participants (12 bilingual; 22 monolingual), and 27 chronic TBI participants (16 bilingual; 11 monolingual). Acute TBI participants were tested 6 months post-injury; chronic TBI participants were tested 12 months or more post-injury. All participants passed performance validity testing. 3X2 ANOVAs were conducted to determine the effect of TBI and language on SDMT written and oral performance. Results A main effect was found between groups (control and TBI groups) on SDMT written, p < .001, ηp² = .19 and SDMT oral p < .001, ηp² = .16. Pairwise comparisons revealed a difference between the control group and TBI groups, with TBI groups performing worse. A main effect for bilingualism/monolingualism was not found; interaction effects emerged between TBI and bilingualism/monolingualism on SDMT written, p < .05, ηp² = .07 and SDMT oral p < .05, ηp² = .07. Conclusion TBI groups performed worse than controls on the SDMT. Relative to monolinguals with TBI, our findings suggest better cognitive recovery of verbal attention and cognitive speed in bilingual TBI participants.

Abstract Objective Traumatic brain injury (TBI) survivors exhibit cognitive deficits. Research suggests that multilingualism can influence neurocognitive performance. We examined the effects of TBI and bilingualism/monolingualism on a test of attention and cognitive speed (i.e., Symbol Digit Modalities Test; SDMT). Method The sample consisted of 55 healthy comparison (27 Spanish-English bilinguals; 28 English-monolinguals), 34 acute TBI (14 Spanish-English bilinguals; 23 English-monolinguals), and 27 chronic TBI (13 Spanish-English bilinguals; 12 English-monolinguals) participants. Acute TBI participants were tested 6 months post-injury; chronic TBI participants were tested 12 months or more post-injury. A series of 3X2 ANOVAs were conducted to determine the effect of TBI and language on SDMT written and oral performance. Results ANOVAs revealed the healthy comparison group outperformed both TBI groups on SDMT written, p = 0.000, ηp2 = 0.21. Also, the healthy comparison and chronic TBI groups outperformed the acute TBI group on SDMT oral, p = 0.000, ηp2 = 0.13. Interaction effects emerged between TBI and bilingualism/monolingualism. On SDMT written and oral, acute TBI English-monolinguals outperformed acute TBI Spanish-English bilinguals; meanwhile, chronic TBI Spanish-English bilinguals outperformed chronic TBI English-monolinguals, p &lt; 0.05, ηp2 = 0.09–0.10. Conclusion The acute TBI group performed worse than healthy comparison adults on both SDMT tasks. Furthermore, the chronic TBI group demonstrated better SDMT oral abilities compared to the acute TBI group. Relative to monolinguals with TBI, our findings suggest better cognitive recovery of attention and cognitive speed in bilingual TBI participants. Future studies with larger sample sizes should examine if learning English first or second impacts Spanish-English bilingual TBI survivors’ SDMT performance compared to English-monolingual TBI survivors.

Abstract Objective The Boston Naming Test (BNT) is a lexical-retrieval task. It has been documented that those with a history of traumatic brain injury (TBI) have reduced performance on the BNT. Bilingualism is also known to impact BNT performances. We examined the relationship of TBI and bilingualism/monolingualism on BNT performances. Method The sample (N = 95) consisted of 36 healthy controls (19 bilingual; 17 monolingual), 32 acute TBI participants (12 bilingual; 20 monolingual), and 27 chronic TBI participants (16 bilingual; 11 monolingual). Acute TBI participants were tested 6 months post-injury and chronic TBI participants were tested 12 months or more post-injury. All participants passed performance validity testing. A 3X2 ANOVA was conducted to determine the effect of TBI and bilingualism/monolingualism on BNT performance. Results A main effect was found for group (i.e., control, 6 month TBI, and 12 month TBI), p < .001, ηp² = .21. Pairwise comparisons revealed that acute TBI participants performed worse than the control and chronic TBI groups. A main effect for bilingualism/ monolingualism was found, p < .001, ηp² = .14; monolinguals performed better on the BNT. No interactions were found between TBI and bilingualism/monolingualism. Conclusions BNT performance improves overtime in TBI and the pattern of improvement post-TBI is not statistically different between bilingual/monolingual groups. Relative to monolinguals, bilingual participants demonstrated worse BNT performance.

Abstract Objective Traumatic brain injury (TBI) is associated with a number of cognitive deficits. Language factors also impact neurocognitive performance. We examined the effects of TBI and bilingualism/monolingualism on a test of attention and executive functioning (Trail Making Test; TMT). Method The sample (N = 96) consisted of 36 healthy controls (19 bilingual; 17 monolingual), 34 acute TBI participants (12 bilingual; 21 monolingual), and 27 chronic TBI participants (16 bilingual; 11 monolingual). Acute TBI participants were tested 6 months post-injury and chronic TBI participants were tested 12 months or more post-injury. 3X2 ANOVAs were conducted to determine the effect of TBI and bilingualism/monolingualism on TMT part A and B. Results Main effects were found between groups (i.e., control and TBI groups) on TMT A, p < .001, ηp² = .17 and TMT B, p < .05, ηp² = .09. Pairwise comparisons revealed a difference only between the control group and the 6-month TBI group, with the latter performing worse. Main effects were found for bilingualism/monolingualism on TMT A, p < .05, ηp² = .04 and TMT B, p < .05, ηp² = .05; monolingual participants performed better than bilingual participants. No interactions emerged. Conclusion Relative to monolinguals, bilingual participants demonstrated worse attention and executive functioning performances 6 months post-TBI; however, 12 months post-TBI, the difference was negligible.

The Relationship

Abstract Objective Traumatic brain injury (TBI) affects neurocognition. Speaking multiple languages can also influence cognitive test performances. We examined the relationship between TBI and monolingualism/bilingualism on a task of attention and response inhibition (Stroop Color Word Test; SCWT). Method The sample (N = 96) consisted of 37 healthy controls (19 bilingual; 18 monolingual), 32 acute TBI participants (12 bilingual; 20 monolingual), and 27 chronic TBI participants (16 bilingual; 11 monolingual). Acute TBI participants were tested 6 months post-injury and chronic TBI participants were tested 12 months or more post-injury. The SCWT included the word (SCWT-W), color (SCWT-C), and color-word interference (SCWT-I) conditions. All participants passed performance validity testing. 3X2 ANOVAs were conducted to examine the relationship between TBI and monolingualism/bilingualism on SCWT performances. Results Group effects (control and TBI groups) were found for all Stroop measures. We found main effects of TBI on SCWT-W, p = .013, ηp² = .09, SCWT-C, p = .001, ηp² = .14, and SCWT-I, p = .022, ηp² = .08, with the controls outperforming acute TBI survivors on SCWT-I, chronic TBI survivors on SCWT-W, and both TBI groups on SCWT-C. We also observed main effects of language for SCWT-C, p = .012, ηp² = .07, and SCWT-I, p = .003, ηp² = .09, with the monolinguals outperforming bilinguals on SCWT-C and SCWT-I. However, no significant interactions between TBI and language were found. Conclusion As expected, the control group outperformed TBI survivors on the SCWT. Monolinguals outperformed bilinguals on all Stroop measures except SCWT-W condition. Our findings seem to suggest that monolingual speakers may have better attention and response inhibition abilities that resulted in better SCWT performance.

Abstract Objective: This study examines the relationship of serum total tau, neurofilament light (NFL), ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1), and glial fibrillary acidic protein (GFAP) with neurocognitive performance in service members and veterans with a history of traumatic brain injury (TBI). Method: Service members (n = 488) with a history of uncomplicated mild (n = 172), complicated mild, moderate, severe, or penetrating TBI (sTBI; n = 126), injured controls (n = 116), and non-injured controls (n = 74) prospectively enrolled from Military Treatment Facilities. Participants completed a blood draw and neuropsychological assessment a year or more post-injury. Six neuropsychological composite scores and presence/absence of mild neurocognitive disorder (MNCD) were evaluated. Within each group, stepwise hierarchical regression models were conducted. Results: Within the sTBI group, increased serum UCH-L1 was related to worse immediate memory and delayed memory (R2Δ = .065–.084, ps < .05) performance, while increased GFAP was related to worse perceptual reasoning (R2Δ = .030, p = .036). Unexpectedly, within injured controls, UCH-L1 and GFAP were inversely related to working memory (R2Δ = .052–.071, ps < .05), and NFL was related to executive functioning (R2Δ = .039, p = .021) and MNCD (Exp(B) = 1.119, p = .029). Conclusions: Results suggest GFAP and UCH-L1 could play a role in predicting poor cognitive outcome following complicated mild and more severe TBI. Further investigation of blood biomarkers and cognition is warranted.

Abstract Objective Traumatic brain injury (TBI) survivors often exhibit problems with executive function (EF). Language use can also impact EF test performances. We examined the effects of TBI and bilingualism/monolingualism on several EF tests. Method The sample (N = 94) consisted of 37 healthy controls (19 bilingual; 18 monolingual), 30 acute TBI participants (10 bilingual; 20 monolingual), and 27 chronic TBI participants (16 bilingual; 11 monolingual). Acute TBI participants were tested 6 months post-injury and chronic TBI participants were tested 12 months or more post-injury. Stroop Color-Word (SCW), Delis-Kaplan Executive Function System Letter Fluency (DKEFS-LF), Trail Making Test part B (TMT-B) and a EF global composite (EF-GC) were used to assess EF. All participants passed performance validity testing. 3X2 ANOVAs were conducted to determine the effect of TBI and bilingualism/monolingualism on EF performances. Results Main effects were found between groups (control and TBI groups) on SCW, p = .046, ηp² = .07, TMT-B, p = .042, ηp² = .07, and EF-GC, p = .005, ηp² = .13; the 6-month TBI group performed worse than controls on TMT-B and EF-GC. Main effects were found for bilingualism/ monolingualism on SCW, p = .012, ηp² = .07, and TMT-B, p = .034, ηp² = .05; monolingual participants performed better than bilingual participants. No significant interactions between TBI and language were found. Conclusion The TBI group underperformed on SCW, TMT-B, and EF-GC compared to controls; relative to monolinguals, bilinguals underperformed on the SCW and TMT-B only. In conclusion, our findings seem to suggest that monolinguals have better cognitive flexibility compared to bilinguals that result in better EF performances.

Abstract Objective We evaluated symptoms of anxiety (via the Hospital Anxiety and Depression Scale; HADS, HADS-A) on Stroop Color Word Test (SCWT) performances in traumatic brain injury (TBI) survivors, as compared to healthy comparison participants (HC). Method The sample consisted of 40 acute TBI survivors [ATBI; 30 normal symptoms of anxiety (NSA); 10 abnormal symptoms of anxiety (ASA)], 30 chronic TBI survivors (CTBI; 16 NSA; 14 ASA), and 50 HC’s (28 NSA; 22 ASA). All participants passed performance validity testing. The SCWT included the word (SCWT-W), color (SCWT-C), and color-word (SCWT-CW) conditions. A series of ANOVAs were used to evaluate SCWT performances. Results ANOVA revealed a main effect group on the SCWT-C, p = .011, and SCWT-CW, p = .018, with HC’s outperforming the ATBI group. Furthermore, HC outperformed both TBI groups on the SCWT-W, p = .004. We also found that the ASA outperformed the NSA group on the SCWT-W, p = .036. No interactions emerged between group and anxiety. Conclusion The HC group outperformed both TBI groups on the SCWT-W, but only the ATBI group on SCWT-C and SCWT-CW. Furthermore, we found that there were only differences between the anxiety groups on the SCWT-W. Our findings highlight that anxiety impacts HC and TBI groups differently on the SCWT.

The present study investigated the utility of the International Classification of Diseases and Related Health Problems, 10th edition (ICD-10) diagnostic criteria for postconcussion syndrome (PCS) symptoms by comparing symptom endorsement rates in a group of patients with mild traumatic brain injury (MTBI) to those of a noninjured control group at one month and three months post-injury. The 110 MTBI patients and 118 control participants were group-matched on age, gender, and education level. Seven of the nine self-reported ICD-10 PCS symptoms differentiated the groups at one month post-injury and two symptoms differentiated the groups at three months post-injury: symptom endorsement rates were higher in the MTBI group at both time periods. Fatiguing quickly and dizziness/vertigo best differentiated the groups at both time periods, while depression and anxiety/tension failed to differentiate the groups at either time period. Collectively, the ICD-10 PCS symptoms accurately classified the MTBI patients at one month post-injury, with the optimal positive test threshold of endorsement of five symptoms coinciding with a sensitivity and specificity of 73% and 61%, respectively. The ICD-10 PCS symptoms were unable to accurately classify the MTBI patients at three months post-injury. (JINS, 2006,12, 111–118.)

The aim of this study was to examine the effect of posttraumatic stress disorder (PTSD) on (a) neuropsychological test performance and (b) self-reported emotional complaints within individuals suffering from postconcussional disorder (PCD) after a mild traumatic brain injury (MTBI). A two-group comparative research design was employed. Two MTBI samples with and without PTSD were assessed with a neuropsychological test battery and the Ruff Neurobehavioral Inventory (RNBI). On the neurocognitive test performances no significant between group differences were found, but the MTBI group with PTSD endorsed a significantly greater number of emotional complaints, especially in the RNBI subscales of anxiety and depression. The patients with PTSD also endorsed a significantly greater number of premorbid sequelae in the RNBI emotional composite scale as well as the RNBI premorbid subscales of pain, anxiety and abuse. In sum, PTSD has a negative impact on emotional but not cognitive functioning within individuals suffering from PCD after a mild TBI.
