Abstract Objective Research shows traumatic brain injury (TBI) survivors underperform compared to healthy comparison participants (HC) on verbal fluency tasks. Verbal fluency is typically comprised of two tasks: letter fluency and semantic fluency. During verbal fluency trials, participants often cluster responses and switch between clusters, which can serve as measures of executive control and organization. Also, research shows that Anglo-Americans (AA) outperformed ethnic minorities on various aspects of cognitive functioning. We examined the relationship between TBI and ethnic diversity on letter fluency, semantic fluency, switching, and clustering. Method The sample included 45 HC adults (21 Hispanics; 24 AA), 33 acute TBI adults (ATBI; 11 Hispanics; 22 AA), and 26 chronic TBI adults (CTBI; 9 Hispanics; 17 AA). Results The groups were well matched, with the exception of gender. ANCOVAs, controlling for gender, revealed HC outperformed ATBI participants on letter fluency, p = .007, ηp2 = .10, letter switching, p = .006, ηp2 = .10, and semantic switching, p = .018, ηp2 = .08. We also found HC outperformed both TBI groups in sematic fluency performances, p = .000, ηp2 = .15. Next, we found Hispanics outperformed AA on letter clustering, p = .003, ηp2 = .09 and semantic clustering, p = .010, ηp2 = .07. Finally, an interaction emerged in letter clustering, p = .044, ηp2 = .06, with the Hispanic ATBI outperforming the AA ATBI group. Conclusion The HC group outperformed both TBI groups only on semantic fluency, but they outperformed the ATBI survivors on letter fluency, letter switching, and semantic switching. Hispanics outperformed AA on letter clustering and semantic clustering, suggesting the use of clustering over switching strategies to provide verbal fluency responses in this group.

Abstract Objective Traumatic brain injury (TBI) impacts neurocognitive function. Language is also known to influence test performances. We examined the relationship between TBI and monolingualism/bilingualism on verbal and design fluency tests. Method The sample (N = 74) consisted of 33 healthy controls (18 bilingual; 15 monolingual), 15 acute TBI participants (6 bilingual; 9 monolingual), and 26 chronic TBI participants (15 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 Delis-Kaplan Executive Function System Letter Fluency (DKEFS-LF), Category Fluency (DKEFS-CF), Category Switching Fluency (DKEFS-CSF), and global verbal fluency composite (DKEFS-GVF) scores assessed verbal fluency; DKEFS fill-dots (DKEFS-FD), empty dots (DFEFS-ED), dot switching (DKEFS-DS), and global design fluency composite (DKEFS-GDF) scores assessed design fluency; and global verbal and non-verbal fluency composite (DKEFS-GF) assessed overall fluency. 3X2 ANOVAs were conducted to evaluate the effect of monolingualism/bilingualism on fluency performance in TBI and controls. Results The groups (control and TBI groups) differed for DKEFS-LF, p = .048, ηp² = .09, DKEFS-CF, p = .000, ηp² = .21, DKEFS-GVF, p = .004, ηp² = .15, DKEFS-ED, p = .008, ηp² = .13, DKEFS-GF, p = .001, ηp² = .20, with controls outperforming TBI groups on the DKEFS-CF, DKEFS-GVF, and DKEFS-GF. Furthermore, controls outperformed acute TBI participants on the DKEFS-LF and DKEFS-ED. Main effects were found for bilingualism/monolingualism on DKEFS-CF, p = .035, ηp² = .06, with bilinguals outperforming monolinguals. No interactions were found. Conclusion The TBI group had poor verbal and design fluency in contrast controls. Unexpectedly, bilinguals outperformed monolinguals on a task of verbal category fluency. Revealing that in the present study bilinguals have better semantic verbal fluency abilities.

The Relationship

The incidence of cognitive impairment in TBI is high, depending on the severity. At the same time, psychopathological symptoms in the form of asthenia, increased anxiety and depression are encountered among patients with TBI. The work studied the relationship between cognitive and psychopathological symptoms in patients with TBI using neuropsychological testing on scales.

AbstractTraumatic brain injury (TBI) is associated with a wide range of physiological, behavioral, emotional, and cognitive sequelae. Litigation status is one of the many factors that has an impact on recovery. The aim of this study was to compare executive functions, postconcussion, and depressive symptoms in TBI patients with and without litigation. A sample of 30 patients with TBI, 15 patients with litigation (medicolegal case [MLC]), and 15 without litigation (non-MLC) was assessed. The tools used were sociodemographic and clinical proforma, executive function tests, Rivermead Post-Concussion Symptom Questionnaire, and Beck Depression Inventory. Assessment revealed that more than 50% of patients showed deficits in category fluency, set shifting, and concept formation. The MLC group showed significant impairment on verbal working memory in comparison to the non-MLC group. The performance of both groups was comparable on tests of semantic fluency, visuospatial working memory, concept formation, set shifting, planning, and response inhibition. The MLC group showed more verbal working memory deficits in the absence of significant postconcussion and depressive symptoms on self-report measures.

The Relationship

External ventricular drainage (EVD) is widely used in patients with a traumatic brain injury (TBI). However, the EVD weaning trial protocol varies and insufficient studies focus on the intracranial pressure (ICP) during the weaning trial. We aimed to establish the relationship between ICP during an EVD weaning trial and the outcomes of TBI. We enrolled 37 patients with a TBI with an EVD from July 2018 to September 2019. Among them, 26 were allocated to the favorable outcome group and 11 to the unfavorable outcome group (death, post-traumatic hydrocephalus, persistent vegetative state, and severe disability). Groups were well matched for sex, pupil reactivity, admission Glasgow Coma Scale score, Marshall computed tomography score, modified Fisher score, intraventricular hemorrhage, EVD days, cerebrospinal fluid output before the weaning trial, and the complications. Before and during the weaning trial, we recorded the ICP at 1-hour intervals to calculate the mean ICP, delta ICP, and ICP burden, which was defined as the area under the ICP curve. There were significant between-group differences in the age, surgery types, and intensive care unit days (p=0.045, p=0.028, and p=0.004, respectively). During the weaning trial, 28 (75.7%) patients had an increased ICP. Although there was no significant difference in the mean ICP before and during the weaning trial, the delta ICP was higher in the unfavorable outcome group (p=0.001). Moreover, patients who experienced death and hydrocephalus had a higher ICP burden, which was above 20 mmHg (p=0.016). Receiver operating characteristic analyses demonstrated the predictive ability of these variables (area under the curve AUC=0.818 [p=0.002] for delta ICP and AUC=0.758 [p=0.038] for ICP burden>20 mmHg). ICP elevation is common during EVD weaning trials in patients with TBI. ICP-related parameters, including delta ICP and ICP burden, are significant outcome predictors. There is a need for larger prospective studies to further explore the relationship between ICP during EVD weaning trials and TBI outcomes.
