Hou Y, Zhou A, Brooks L, Reid D, Turkstra L, MacDonald S. Rehabilitation access for individuals with cognitive-communication challenges after traumatic brain injury: A co-design study with persons with lived experience. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2024; 59:648-664. [PMID: 37189286 DOI: 10.1111/1460-6984.12895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Accepted: 04/21/2023] [Indexed: 05/17/2023]
Abstract
BACKGROUND Adults with traumatic brain injuries (TBI) frequently experience cognitive, emotional, physical and communication deficits that require long-term rehabilitation and community support. Although access to rehabilitation services is linked to positive outcomes, there can be barriers to accessing community rehabilitation related to system navigation, referral processes, funding, resource allocation and communications required to ensure access. AIMS This study aimed to identify barriers to accessing insurer funding for rehabilitation and healthcare services, for adults with TBI injured in motor vehicle collisions (MVCs). METHODS We used a co-design approach to collaborate with persons with lived experience to design a survey of adults who sustained a TBI in an MVC. The survey examined access to insurer funding for rehabilitation services and was disseminated through brain injury networks in Ontario, Canada. RESULTS Respondents (n = 148) identified multiple barriers to accessing rehabilitation services through insurer funding, including delays of more than 2 years (49%), mandatory duplicative assessments (64%) and invasion of privacy (55%). Speech-language therapy and neuropsychological services were denied most frequently. Negative experiences included insurers' poor understanding of TBI symptoms, denials of services despite medical evidence demonstrating need and unsupportive insurer interactions. Although 70% of respondents reported cognitive-communication difficulties, accommodations were rarely provided. Respondents identified supports that would improve insurer and healthcare communications and rehabilitation access. CONCLUSION & IMPLICATIONS The insurance claims process had many barriers for adults with TBI, limiting their access to rehabilitation services. Barriers were exacerbated by communication deficits. These findings indicate a role for Speech-language therapists in education, advocacy and communication supports during the insurance process specifically as well as rehabilitation access processes in general. WHAT THIS PAPER ADDS What is already known on this subject There is extensive documentation of the long-term rehabilitation needs of individuals with traumatic brain injury (TBI) and their challenges in accessing rehabilitation services over the long term. It is also well known that many individuals with TBI have cognitive and communication deficits that affect their interactions in the community, including with healthcare providers, and that SLTs can train communication partners to provide communication supports to individuals with TBI in these communication contexts. What this study adds This study adds important information about barriers to accessing rehabilitation, including barriers to accessing SLT services in the community. We asked individuals with TBI about challenges to accessing auto insurance funding for private community services, and their responses illustrate the broader challenges individuals with TBI face in communicating their deficits, conveying service needs, educating and convincing service administrators and self-advocating. The results also highlight the critical role that communication plays in healthcare access interactions, from completing forms to reviewing reports and funding decisions, to managing telephone calls, writing emails and explaining to assessors. What are the clinical implications of this work? This study shows the lived experience of individuals with TBI in overcoming barriers to accessing community rehabilitation. The results show that best practices in intervention should include evaluating rehabilitation access, which is a critical step in patient-centred care. Evaluation of rehabilitation access includes evaluating referral and navigation, resource allocation and healthcare communications, and ensuring accountability at each step, regardless of model of service delivery or funding source. Finally, these findings show the critical role of speech-language therapists in educating, advocating and supporting communications with funding sources, administrators and other healthcare providers.

Long Noncoding RNA VLDLR-AS1 Levels in Serum Correlate with Combat-Related Chronic Mild Traumatic Brain Injury and Depression Symptoms in US Veterans. Int J Mol Sci 2024; 25:1473. [PMID: 38338752 PMCID: PMC10855201 DOI: 10.3390/ijms25031473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 01/15/2024] [Accepted: 01/22/2024] [Indexed: 02/12/2024] Open
Abstract
More than 75% of traumatic brain injuries (TBIs) are mild (mTBI) and military service members often experience repeated combat-related mTBI. The chronic comorbidities concomitant with repetitive mTBI (rmTBI) include depression, post-traumatic stress disorder or neurological dysfunction. This study sought to determine a long noncoding RNA (lncRNA) expression signature in serum samples that correlated with rmTBI years after the incidences. Serum samples were obtained from Long-Term Impact of Military-Relevant Brain-Injury Consortium Chronic Effects of Neurotrauma Consortium (LIMBIC CENC) repository, from participants unexposed to TBI or who had rmTBI. Four lncRNAs were identified as consistently present in all samples, as detected via droplet digital PCR and packaged in exosomes enriched for CNS origin. The results, using qPCR, demonstrated that the lncRNA VLDLR-AS1 levels were significantly lower among individuals with rmTBI compared to those with no lifetime TBI. ROC analysis determined an AUC of 0.74 (95% CI: 0.6124 to 0.8741; p = 0.0012). The optimal cutoff for VLDLR-AS1 was ≤153.8 ng. A secondary analysis of clinical data from LIMBIC CENC was conducted to evaluate the psychological symptom burden, and the results show that lncRNAs VLDLR-AS1 and MALAT1 are correlated with symptoms of depression. In conclusion, lncRNA VLDLR-AS1 may serve as a blood biomarker for identifying chronic rmTBI and depression in patients.

[PMID: 37673685 PMCID: PMC10634649 DOI: 10.1212/wnl.0000000000207819] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Accepted: 07/10/2023] [Indexed: 09/08/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Traumatic brain injuries (TBIs) are associated with increased risk of dementia, but whether lifetime TBI influences cognitive trajectories in later life is less clear. Cognitive interventions after TBI may improve cognitive trajectories and delay dementia. Because twins share many genes and environmental factors, we capitalize on the twin study design to examine the association between lifetime TBI and cognitive decline. METHODS Participants were members of the National Academy of Sciences-National Research Council's Twin Registry of male veterans of World War II with self or proxy-reported history of TBI and with up to 4 observations over 12 years of the modified Telephone Interview for Cognitive Status (TICS-m). We used linear random-effects mixed models to analyze the association between TBI and TICS-m in the full sample and among co-twins discordant for TBI. Additional TBI predictor variables included number of TBIs, severity (loss of consciousness [LOC]), and age of first TBI (age <25 vs 25+ years [older age TBI]). Models were adjusted for age (centered at 70 years), age-squared, education, wave, twin pair, lifestyle behaviors, and medical conditions. RESULTS Of 8,662 participants, 25% reported TBI. History of any TBI (β = -0.56, 95% CI -0.73 to -0.39), TBI with LOC (β = -0.51, 95% CI -0.71 to -0.31), and older age TBI (β = -0.66, 95% CI -0.90 to -0.42) were associated with lower TICS-m scores at 70 years. TBI with LOC (β = -0.03, 95% CI -0.05 to -0.001), more than one TBI (β = -0.05, 95% CI -0.09 to -0.002,), and older age TBI (β = -0.06, 95% CI -0.09 to -0.03) were associated with faster cognitive decline. Among monozygotic pairs discordant for TBI (589 pairs), history of any TBI (β = -0.55, 95% CI -0.91 to -0.19) and older age TBI (β = -0.74, 95% CI -1.22 to -0.26) were associated with lower TICS-m scores at 70 years. Those with more than one TBI (β = -0.13, 95% CI -0.23 to -0.03) and older age TBI (β = -0.07, 95% CI -0.13 to -0.002) showed greater cognitive decline compared with their co-twin without TBI. DISCUSSION These findings support an association of the effect of TBI on cognitive score and the rapidity of cognitive decline in later life. The results in monozygotic pairs, who share all genes and many exposures, particularly in early life, provide additional evidence of a causal relationship between TBI and poorer late-life cognitive outcomes.

Abstract
OBJECTIVE/BACKGROUND Psychiatric symptoms and cognitive deficits add significantly to impairment in academic achievement and quality of life in patients with narcolepsy. The primary aim of this study was to evaluate the prevalence of psychiatric disorders and executive dysfunctions, secondly to explore the association between psychiatric comorbidity, executive dysfunctions, subjective and objective sleep measures, and severity of cerebrospinal fluid (CSF) hypocretin-1 deficiency in pediatric narcolepsy type 1 (PNT1). PATIENTS/METHODS Cross-sectional study of 59 consecutively included PNT1 patients (age: 6-20 years; 34:25 girls: boys; 54/59 H1N1 (Pandemrix®)-vaccinated). Core narcolepsy symptoms including subjective sleepiness, polysomnography and multiple sleep latency test results, CSF hypocretin-1 levels, psychiatric disorders (by semistructured diagnostic interview Kaufmann Schedule for Affective Disorders and Schizophrenia Present and Lifetime version (KSADS)), and executive dysfunction (by Behavior Rating of Executive Function (BRIEF)) were assessed. RESULTS 52.5% of the patients had one or more psychiatric comorbid disorder, and 64.7% had executive dysfunction in a clinically relevant range, with no sex difference in prevalence, while older age was associated with poorer executive function (p=0.013). Having any psychiatric comorbid disorder was associated with poorer executive functions (p=0.001). CSF hypocretin-1 deficiency severity was significantly associated with presence of psychiatric comorbidity (p=0.022) and poorer executive functions (p=0.030), and poorer executive functions was associated with subjective sleepiness (p=0.009). CONCLUSIONS The high occurrence of, and association between, psychiatric comorbidity and executive dysfunction underlines the importance of close attention to both these comorbidities in clinical care of NT1.

Key-DeLyria SE, Rogalski Y, Bodner T, Weichselbaum A. Is sentence ambiguity comprehension affected after mild traumatic brain injury? Results suggest cognitive control is more important than diagnosis. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2022; 57:990-1005. [PMID: 35611868 DOI: 10.1111/1460-6984.12734] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Accepted: 04/15/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Individuals with mild traumatic brain injury (mTBI) may experience chronic cognitive-linguistic impairments that are difficult to evaluate with existing measures. Garden path sentences are linguistically complex sentences that lead readers down a path to an incorrect interpretation. Previous research indicates many individuals, with or without mTBI, may have difficulty fully resolving the ambiguity of garden path sentences, a skill which may require cognitive control. Evidence suggests cognitive control can be impacted by mTBI. Thus, impairments in cognitive control are expected to correlate with interpreting ambiguous sentences. AIMS To examine the relationship between cognitive control and the processing of ambiguous garden path sentences in adults with mTBI. We predict individuals with mTBI will perform more poorly on ambiguous sentence tasks compared with a control group. Further, we predict that performance on this task will correlate with measures of cognitive control and working memory. METHODS & PROCEDURES A total of 20 adults with mTBI history and 44 adults with no significant neurological history were recruited from the community. Participants completed a computerized, ambiguous sentence measure with carefully designed comprehension questions and an abbreviated neuropsychological battery of cognitive-linguistic tasks. OUTCOMES & RESULTS Participants performed similarly on sentence ambiguity resolution measures across groups with a wide range in performance. A comprehension measure aimed at identifying full ambiguity resolution correlated with cognitive control across groups. CONCLUSIONS & IMPLICATIONS A link between cognitive control and linguistic ambiguity is confirmed in a comprehension measure by the current findings. mTBI history did not appear to change the nature of the relationship between cognitive control and ambiguity resolution. High individual variability on sentence and cognitive control measures across groups suggest that if an impairment were present, it would affect both types of tasks. Thus, testing cognitive communication following mTBI should specifically examine complex cognitive and linguistic processing. WHAT THIS PAPER ADDS What is already known on the subject Cognitive control and ambiguous sentence processing are known to be linked, but the circumstances and individual variability associated with when cognitive control is recruited to support sentence processing are not fully understood. Very little is known about sentence processing following TBI history, despite cognitive control commonly being impaired following mild TBI. Thus, our study was necessary to explore the theoretical and clinical relationships between cognitive control and ambiguous sentence processing in individuals with mild TBI history. What this paper adds to existing knowledge This study adds to our understanding of how cognitive control and ambiguous sentence processing are linked in those with mild TBI history, and similar to the few previous studies, there were no group differences in cognitive or sentence measures. The positive correlation between cognitive control on Stroop and a particular ambiguous sentence comprehension question targeting inhibitory control highlights that any relationship between abilities or assessment tasks must be very specific to tasks with overlapping requirements, such as inhibition. What are the potential or actual clinical implications of this work? The relationship between cognitive and ambiguous sentence measures highlights the need to assess all areas of cognition and communication in those with mild TBI history without assuming that impairments in cognitive performance will relate to communication. The overlap between abilities is highly specific and must be explored on a case-by-case basis in those with mild TBI. Evaluation and treatment should still be individualized based on the functional communication profile of the client.

Abstract
OBJECTIVES In the United States, up to 70% of youth experiencing homelessness smoke cigarettes. Many are interested in quitting; however, little is known about psychosocial factors influencing smoking relapse in this population. This study, part of a larger project to develop an optimized smoking cessation intervention for youth experiencing homelessness, aimed to describe how psychosocial factors influence smoking relapse in this group. METHODS This study describes the smoking relapse experiences of 26 youth tobacco users, aged 14-24 years, who were recruited from a homeless drop-in center in Ohio. We conducted semi-structured interviews to understand how stress, opportunity, and coping contribute to smoking relapse. RESULTS Five themes emerged from the data: (1) smoking as a lapse in emotional self-regulation in response to stress; (2) smoking as active emotional self-regulation in response to stress; (3) social opportunities facilitate smoking in the context of emotion-focused stress coping; (4) problem-focused stress coping; and (5) opportunity facilitates smoking relapse. CONCLUSIONS Stress was a primary driver of smoking relapse among youth experiencing homelessness, yet social and environmental opportunities to smoke also precipitated relapse. Interventions to improve abstinence among this population should target foundational stressors, coping skills, social supports, and nicotine dependence.

Abstract
Cognitive reserve (CR) has been proposed to account for functional outcome differences in brain pathology and its clinical manifestations. The purpose of our paper is to systematically review the effects of CR on cognitive outcomes in individuals with neurodegenerative and structural CNS diseases. We performed a systematic search of PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and PsychInfo using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Seventeen studies met the predetermined inclusion criteria and were selected for review. Education level was the most commonly used measure for CR, and various neuropsychological tests were used to measure cognitive outcomes. Regardless of the CNS disease of the individuals, almost all of the studies reported a positive association between CR and cognitive outcomes when they were evaluated cross-sectionally. However, when evaluated longitudinally, CR had either no effect on, or a negative association with, cognitive outcomes. Based on studies across a broad spectrum of CNS diseases, our findings suggest that CR may serve as a predictor of cognitive outcomes in individuals with CNS diseases. However, studies to date are limited by a lack of imaging analyses and standardized assessment strategies. The ability to use a standardized measure to assess the longitudinal effects of CR may allow for the development of more targeted treatment methods, resulting in improved disease outcomes for individuals.

Abstract
Objective To investigate how gait parameters in children with traumatic brain injury (TBI) versus typically developing (TD) children are influenced by secondary concurrent tasks and examine the correlations between gait parameters and attention and balance in children with TBI. Methods Sixteen children with TBI (mean age, 11.63±1.89 years) and 22 TD controls (mean age, 11.41±2.24 years) participated in this case-control study. Attention and functional balance were measured using the Children’s Color Trail Test (CCTT) and Pediatric Balance Scale (PBS). All participants first walked without concurrent tasks and then with concurrent motor and cognitive tasks. The APDM Mobility Lab was used to measure gait parameters, including gait velocity, stride length, stride duration, cadence, and double support time. Repeated-measures analysis of variance and Spearman correlation coefficient were used for the analysis. Results Children with TBI showed significantly more deterioration in gait performance than TD children (p<0.05). Concurrent tasks (motor and cognitive) significantly decreased gait velocity and cadence and increased stride time; the differences were more obvious during the concurrent cognitive task. A moderate correlation was found between gait parameters (gait velocity and stride length) and CCTT-2 and PBS scores in children with TBI. Conclusion Gait performance may be affected by task complexity following TBI. Attention and balance deficits caused deterioration in gait performance under the concurrent task condition in children with TBI. This study illustrates the crucial role of task demand and complexity in dual-task interference.
