Virtual reality immerses you in your mind: the experience and stress-reduction benefits of VR mindfulness modules in persons with TBI.

OBJECTIVE: This pilot study tested the feasibility and stress reduction effectiveness of a one-time virtual reality mindfulness module (VRMM) in individuals with mild-to-moderate traumatic brain injury (TBI). METHODS: Thirty-eight participants participated in a pilot study utilizing a mixed methods convergent parallel design. Pretest and posttest stress levels were collected; participants engaged in a brief 4-question qualitative interview. Mann Whitney U and Wilcoxon Signed Rank Tests were used. Qualitative analysis utilized grounded theory. RESULTS: Post-VRMM, two-thirds (24) of participants had a statistically significant decrease in stress levels. A key qualitative finding indicated that participants found the immersiveness and realism of the VR environments helpful in compensating for cognitive deficits resulting from TBI. There were no adverse side effects reported, indicating that well-designed VRMMs that minimize motion-induced adverse effects are well tolerated in persons with TBI. CONCLUSION: A guided mindfulness activity in a VR environment was well tolerated, and participants overall found VRMM effective in reducing stress levels. VR-based environments have potential to harness guided mindfulness practice and may support persons with TBI to enhance concentration. Further application of this technology in TBI rehabilitation is promising and warrants future research to explore the benefit of VR in improving rehabilitation outcomes.

Protocol for Safety and Efficacy of MLC901 (NeuroAiD II) in Patients With Moderate Traumatic Brain Injury: A Randomized Double-Blind Placebo-Controlled Trial (ANDROMEDA).

BACKGROUND AND OBJECTIVES: Traumatic brain injury (TBI) remains a leading cause of death and disability, affecting approximately 69 million individuals each year worldwide. A significant portion of TBI research has focused on treatments for neuroprotection and/or neurorecovery, with most failing to transition to successful clinical applications despite promising animal/in vitro study results. MLC901 (NeuroAiD II), with origins from a traditional Chinese medicine, has been shown to exhibit both neuroprotective and neuroregenerative properties in in vitro and animal studies for stroke and TBI. Clinical trials have demonstrated its safety with significant improvements in some functional outcome and cognitive domain measures. The objective of this study is to determine the efficacy and safety of MLC901 (NeuroAiD II) vs placebo in adult patients with moderate TBI. METHODS: This is a multicenter randomized double-blind placebo-controlled trial that aims to enroll 120 adult patients with moderate TBI receiving standard of care in 2 arms: MLC901 vs placebo for a treatment period of 6 months with a further follow-up of 3 months. The total duration of the study is 9 months. The primary end point is Glasgow Outcome Scale Extended (GOS-E) at 6 months. Other assessments include mortality at 6 months, GOS-E, Glasgow Coma Scale, Montreal Cognitive Assessment Filipino Version, Frontal Assessment Battery Conflicting Instructions and Go-No-Go, Rivermead Post-Concussion Symptom Questionnaire, Barthel Index, Hospital Anxiety and Depression Scale, and Health related Quality of life (EQ-5D) at 1, 3, 6, and 9 months. Cerebral swelling at baseline and at 1 and 2 weeks will also be documented. Adverse events and drug compliance will also be monitored. EXPECTED OUTCOMES: We expect to find a significant improvement in functional and cognitive outcomes in patients who were given MLC901. DISCUSSION: Previous studies on the effect of MLC901 in adult patients with moderate TBI showed positive results; However, these studies are limited by the small number of patients. This study will establish a more definitive role of MLC901 in improving functional and cognitive outcomes in patients with moderate TBI.

Effects of Neurofeedback on Cognitive Function, Productive Activity, and Quality of Life in Patients With Traumatic Brain Injury: A Randomized Controlled Trial.

BACKGROUND: Cognitive impairment is common in patients with traumatic brain injury (TBI). Studies that have examined the effectiveness of neurofeedback (NFB) on cognitive function following TBI have had poor study designs and small sample sizes. OBJECTIVES: This randomized controlled trial assessed the effects of low-resolution tomography Z-score NFB (LZNFB) and theta/beta NFB on cognitive impairment, return to productive activity, and quality of life in patients with TBI. METHODS: We randomly assigned 87 patients with TBI with cognitive impairment to LZNFB, theta/beta NFB, or usual care (UC) groups. Patients in both NFB groups received weekly 60-minute treatment for 10 weeks, and those in the control group received UC and telephone interviews for 10 weeks. The primary outcome was cognitive function as measured by performance on cognitive tasks; the secondary outcomes included productive activity and quality of life based on the Community Integration Questionnaire-revised (CIQ-R) and the Quality of Life after Brain Injury (QOLIBRI), respectively, at baseline and immediately after the last intervention. RESULTS: The LZNFB group exhibited significantly greater improvements in immediate recall, delayed recall, recognition memory, and selective attention compared with the UC group; the theta/beta NFB group exhibited improvements in only immediate memory and selective attention (P < .05). The total CIQ-R scores of the LZNFB group after treatment were significantly improved than those of the UC group were. CONCLUSION: Consecutive LZNFB achieved therapeutic effects in memory, attention, and productive activity, whereas theta/beta NFB improved memory and attention in patients with TBI.This trial was prospectively registered at ClinicalTrial.gov (registration number: NCT03515317; https://clinicaltrials.gov/ct2/show/NCT03515317).

Advancing care and research for traumatic brain injury: a roadmap.

Across all segments of society in the United States, millions of adults and children experience a traumatic brain injury (TBI) each year, which may pose lifetime health and financial burdens in the billions of dollars. Efforts have been made to advance research and care with goals to improve awareness of the causes and consequences of TBI, but gaps still remain in understanding TBI and delivering high-quality care to everyone who needs it both in military and civilian life. At the request of the Department of Defense, the National Academies of Sciences, Engineering and Medicine recently convened experts to address existing gaps in brain injury science and systems of care. Although many people who experience a TBI recover fully, others experience long-term physical, emotional, and often financial consequences to the patient and family system, and require ongoing accommodations to support their return to the communities in which they live, learn, and work. A holistic approach within the context of osteopathic medicine may be helpful and enhance contributions within the field. This article will discuss the roadmap to help guide the field, including key conclusions and recommendations for actions to advance progress over the next decade while embracing a comprehensive bio-psycho-socio-ecological model of TBI care bringing in the distinctive osteopathic approach not only to improve care and outcomes, but also to understand patient and family experiences on their TBI journey.

Boswellia serrata extract shows cognitive benefits in a double-blind, randomized, placebo-controlled pilot clinical trial in individuals who suffered traumatic brain injury.

BACKGROUND: Traumatic brain injury (TBI) is a major cause of death and disability. TBI can result in neuropsychiatric and cognitive problems as well as neurodegenerative pathologies that can appear right after or develop and persist years after injury. METHOD: We conducted a double-blind, randomized, placebo-controlled clinical trial on patients who suffered from TBI three months to three years ago. The patients were randomized to placebo (n = 34) or K-Vie™ group (n = 46) for a treatment period of 3 months. The main primary outcomes include cognitive assessment in the Rey Auditory Verbal Learning Test-Recognition Test (RAVLT), Wechsler adult intelligence Digit Symbol Substitution Test (DSST) and trail-making test part B (TMT-B). Assessments were performed at baseline and at the month 3 follow-up visit. Linear mixed models were carried out to evaluate cognitive changes from baseline across all cognitive assessment tests. RESULT: The current study showed significant (p < 0.05) improvement in cognitive function of patients who were given K-Vie™ compared with placebo across the RAVLT, DSST and TMT-B performance assessments. A larger cohort would be beneficial to further confirm the clinical utility of K-Vie™ and assess its effects in acute phases of TBI.

Psychotherapy and Art Therapy: A pilot study of group treatment for patients with traumatic brain injury.

Here we investigated the efficacy of group Psychotherapy and Art Therapy in rebuilding self-identity after traumatic brain injury (TBI), assessing their effects on psychological aspects in twelve patients with severe TBI. Overall, the results show an increased ability to adapt to the experiences of life as well as a higher level of awareness, social functioning and emotional autoregulation. Furthermore, patients exhibited a reduction in depressive symptoms and in the perception of physical problems. Results highlight the importance of treatments focusing on the patients' emotional needs, in addition to the classic rehabilitation (i.e. physiotherapy, cognitive therapy).

Effects of neurological music therapy on behavioural and emotional recovery after traumatic brain injury: A randomized controlled cross-over trial.

Traumatic brain injury (TBI) causes deficits in executive function (EF), as well as problems in behavioural and emotional self-regulation. Neurological music therapy may aid these aspects of recovery. We performed a cross-over randomized controlled trial where 40 persons with moderate-severe TBI received a 3-month neurological music therapy intervention (2 times/week, 60 min/session), either during the first (AB, n = 20) or second (BA, n = 20) half of a 6-month follow-up period. The evidence from this RCT previously demonstrated that music therapy enhanced general EF and set shifting. In the current study, outcome was assessed with self-report and caregiver-report questionnaires performed at baseline, 3-month, 6-month, and 18-month stages. The results showed that the self-reported Behavioural Regulation Index of the Behaviour Rating Inventory of Executive Function (BRIEF-A) improved more in the AB than BA group from baseline to 3-month stage and the effect was maintained in the 6-month follow-up. No changes in mood or quality of life questionnaires were observed. However, a qualitative content analysis of the feedback revealed that many participants experienced the intervention as helpful in terms of emotional well-being and activity. Our results suggest that music therapy has a positive effect on everyday behavioural regulation skills after TBI.

Sustained Dysbiosis and Decreased Fecal Short-Chain Fatty Acids after Traumatic Brain Injury and Impact on Neurologic Outcome.

Traumatic brain injury (TBI) alters microbial populations present in the gut, which may impact healing and tissue recovery. However, the duration and impact of these changes on outcome from TBI are unknown. Short-chain fatty acids (SCFAs), produced by bacterial fermentation of dietary fiber, are important signaling molecules in the microbiota gut-brain axis. We hypothesized that TBI would lead to a sustained reduction in SCFA producing bacteria, fecal SCFAs concentration, and administration of soluble SCFAs would improve functional outcome after TBI. Adult mice (n = 10) had the controlled cortical impact (CCI) model of TBI performed (6 m/sec, 2-mm depth, 50-msec dwell). Stool samples were collected serially until 28 days after CCI and analyzed for SCFA concentration by high-performance liquid chromatography-mass spectrometry/mass spectrometry and microbiome analyzed by 16S gene sequencing. In a separate experiment, mice (n = 10/group) were randomized 2 weeks before CCI to standard drinking water or water supplemented with the SCFAs acetate (67.5 mM), propionate (25.9 mM), and butyrate (40 mM). Morris water maze performance was assessed on post-injury Days 14-19. Alpha diversity remained stable until 72 h, at which point a decline in diversity was observed without recovery out to 28 days. The taxonomic composition of post-TBI fecal samples demonstrated depletion of bacteria from Lachnospiraceae, Ruminococcaceae, and Bacteroidaceae families, and enrichment of bacteria from the Verrucomicrobiaceae family. Analysis from paired fecal samples revealed a reduction in total SCFAs at 24 h and 28 days after TBI. Acetate, the most abundant SCFA detected in the fecal samples, was reduced at 7 days and 28 days after TBI. SCFA administration improved spatial learning after TBI versus standard drinking water. In conclusion, TBI is associated with reduced richness and diversity of commensal microbiota in the gut and a reduction in SCFAs detected in stool. Supplementation of soluble SCFAs improves spatial learning after TBI.

Feasibility of a rhythmic auditory stimulation gait training program in community-dwelling adults after TBI: A case report.

BACKGROUND: Traumatic brain injury has multiple impacts on gait including decreased speed and increased gait variability. Rhythmic auditory stimulation (RAS) gait training uses the rhythm and timing structure of music to train and ultimately improve slow and variable walking patterns. OBJECTIVE: To describe the feasibility of RAS gait training in community-dwelling adults with traumatic brain injury (TBI). A secondary objective is to report changes in spatiotemporal gait parameters and clinical measures of balance and walking endurance. METHODS: Two individuals with a TBI participated in nine sessions of gait training with RAS over a 3-week period. At baseline, post-training and 3-week follow-up, spatiotemporal parameters of walking were analyzed at preferred pace, maximum pace and dual-task walking conditions. Secondary outcomes included the Community Balance and Mobility Scale and the 6-Minute Walk Test. Feasibility was assessed using reports of physical fatigue, adverse event reporting, and perceived satisfaction. RESULTS: Both participants completed all 9 planned intervention sessions. The sessions were well tolerated with no adverse events. Participant 1 and 2 exhibited different responses to the intervention in line with the therapeutic goals set with the therapist. Participant 1 exhibited improved speed and decreased gait variability. Participant 2 exhibited reduced gait speed but less fatigue during the 6MWT. CONCLUSIONS: RAS was found to be a safe and feasible gait intervention with the potential to improve some aspects of gait impairments related to gait speed, gait variability, dynamic balance and walking endurance. Further investigation including a pilot randomized controlled trial is warranted.

In search of the 'self': Holistic rehabilitation in restoring cognition and recovering the 'self' following traumatic brain injury: A case report.

BACKGROUND: Following mild-moderate traumatic brain injury (TBI), an individual experiences a range of emotional changes. It is often difficult for the patient to reconcile with their post-injury persona, and the memory of pre-injury personhood is particularly painful. Insight into one's cognitive deficits subsequent to injury can lead to an existential crisis and a sense of loss, including loss of self. OBJECTIVE: Restoration of cognitive functions and reconciliation with loss of pre-traumatic personhood employing a holistic method of neuropsychological rehabilitation in a patient suffering from TBI. METHODS: Ms. K.S, a 25-year-old female, presented with emotional disturbances following TBI. She reported both retrograde and anterograde amnesia. A multidimensional holistic rehabilitation was planned. Treatment addressed cognitive deficits through the basic functions approach. Cognitive behavioural methods for emotional regulation like diary writing helped reduce irritability and anger outbursts. Use of social media created new modes of memory activation and interactions. Compensatory strategies were used to recover lost skills, music-based attention training helped foster an individualised approach to the sense of one's body and self. RESULTS: As a result of these differing strategies, changes were reflected in neuro-psychological tests, depression score and the patient's self-evaluation. This helped generate a coherent self-narrative. CONCLUSION: Treatment challenges in such cases are increased due to patient's actual deficits caused by neuronal/biochemical changes. Innovative and multi-pronged rehabilitation strategies which involve everyday activities provided an answer to some of these problems. This method of rehabilitation may provide an optimistic context for future research.

Degeneration of core neural tracts for emotional regulation in a patient with traumatic brain injury: A case report.

RATIONALE: Several brain structures, including the orbital prefrontal cortex, ventrolateral prefrontal cortex, dorsolateral prefrontal cortex, amygdala, and anterior cingulate cortex, are considered key structures in the neural circuitry underlying emotion regulation. We report on a patient showing behavior changes and degeneration of core neural tracts for emotional regulation following traumatic brain injury (TBI). PATIENT CONCERNS: A 51-year-old male patient suffered an in-car accident. The patient lost consciousness for approximately 30 days, and his Glasgow Coma Scale score was 3. He underwent stereotactic drainage for traumatic intraventricular and intracerebral hemorrhages. At approximately 6.5-year after onset, he began to show disinhibition behaviors such as shouting with anger, which worsened over time. At approximately 8-year after onset, he showed severe depression signs and disinhibition, including violence. DIAGNOSES: The patient who showed delayed-onset behavioral changes (disinhibition and depression). INTERVENTIONS: Diffusion tensor imaging data were acquired at 3 months and 8 years after TBI onset. OUTCOMES: The patient showed degeneration of core neural tracts for emotional regulation that was associated with delayed behavioral changes following TBI. On both 3-month and 8-year diffusion tensor tractographies (DTTs), the right dorsolateral prefronto-thalamic tract, ventrolateral prefronto-thalamic tract, orbital prefronto-thalamic tract, uncinate fasciculus, and both cinguli were reconstructed whereas other neural tracts were not reconstructed. Compared with the 3-month DTT, all reconstructed neural tracts on the 8-year DTT were narrow, except for the left cingulum, which showed new transcallosal fibers between both anterior cingula. The fractional anisotropy and tract volume of all reconstructed neural tracts were lower on the 8-year DTT than the 3-month DTT, except for the tract volume of left cingulum. LESSONS: The evaluation of dorsolateral, ventrolateral, and orbital prefronto-thalamic tract, uncinate fasciculus, and cingulum using follow-up DTTs is useful when a patient with TBI shows delayed-onset behavioral problems.

Blue-wavelength light therapy for post-traumatic brain injury sleepiness, sleep disturbance, depression, and fatigue: A systematic review and network meta-analysis.

OBJECTIVE: This review aimed to determine the efficacy of blue-wavelength light therapy (BWLT) for post-traumatic brain injury (TBI) sleepiness, sleep disturbance, depression, and fatigue. METHODS: Pubmed, Scopus, Web of Science, Cochrane Library, Academic Search Complete, and CINAHL. Included trials were randomized controlled trials (RCTs) of BWLT in adults with a history of TBI. Outcomes of interest included sleepiness, sleep disturbance, depression, or fatigue. Two reviewers independently screened the searched items, selected the trials, extracted the data, and rating the quality of trials. We aggregated the data using a random-effect, frequentist network meta-analysis (NMA). RESULTS: We searched the databases on July 4, 2020. This review included four RCTs of 117 patients with a history of TBI who were randomized to received BWLT, amber light therapy (ALT), or no light therapy (NLT). Moderate-quality evidence revealed that: i) BWLT was significantly superior to NLT in reducing depression (SMD = 0.81, 95% CI = 0.20 to 1.43) ii) BWLT reduced fatigue at a significantly greater extent than NLT (SMD = 1.09, 95% CI = 0.41 to 1.76) and ALT (SMD = 1.00, 95% CI = 0.14 to 1.86). Low-quality evidence suggested that BWLT reduced depression at a greater extent than ALT (SMD = 0.57, 95% CI = 0.04 to 1.10). Low-quality evidence found that the dropout rates of those receiving BWLT and ALT were not significantly different (RR = 3.72, 95% CI = 0.65 to 21.34). CONCLUSION: Moderate-quality evidence suggests that BWLT may be useful for post-TBI depression and fatigue.

Feasibility and Efficacy of a Resiliency Intervention for the Prevention of Chronic Emotional Distress Among Survivor-Caregiver Dyads Admitted to the Neuroscience Intensive Care Unit: A Randomized Clinical Trial.

Importance: To our knowledge, there are no evidence-based interventions to prevent chronic emotional distress (ie, depression, anxiety, and posttraumatic stress [PTS]) in critical care survivors and their informal caregivers. Objective: To determine the feasibility and preliminary effect of the novel dyadic resiliency intervention Recovering Together (RT) on reducing symptoms of depression, anxiety, and PTS among hospitalized patients and their informal caregivers. Design, Setting, and Participants: This single-blind, pilot randomized clinical trial of RT vs an educational control was conducted among 58 dyads in which either the survivor or caregiver endorsed clinically significant symptoms of depression, anxiety, or PTS. The study was conducted in the neuroscience intensive care unit at Massachusetts General Hospital. Data were collected from September 2019 to March 2020. Interventions: Both RT and control programs had 6 sessions (2 at bedside and 4 via live video after discharge), and both survivor and caregiver participated together. Main Outcomes and Measures: The primary outcomes were feasibility of recruitment and intervention delivery, credibility, and satisfaction. The secondary outcomes included depression and anxiety (measured by the Hospital Depression and Anxiety Scale), PTS (measured by the PTSD Checklist-Civilian Version), and intervention targets (ie, mindfulness, measured by the Cognitive and Affective Mindfulness Scale-Revised; coping, measured by the Measure of Current Status-Part A; and dyadic interpersonal interactions, measured by the Dyadic Relationship Scale). Main outcomes and targets were assessed at baseline, 6 weeks, and 12 weeks. Results: The 58 dyads were randomized to RT (29 dyads [50.0%]; survivors: mean [SD] age, 49.3 [16.7] years; 9 [31.0%] women; caregivers: mean [SD] age, 52.4 [14.3] years; 22 [75.9%] women) or control (29 dyads [50.0%]; survivors: mean [SD] age, 50.3 [16.4] years; 12 [41.3%] women; caregivers, mean [SD] age, 52.1 [14.9], 17 [58.6%] women). Feasibility (recruitment [76%], randomization [100%], and data collection [83%-100%]), adherence (86%), fidelity (100%; κ = 0.98), satisfaction (RT: 57 of 58 [98%] with scores >6; control: 58 of 58 [100%] with scores >6), credibility (RT: 47 of 58 [81%] with scores >6; control: 46 of 58 [80%] with scores >6), and expectancy (RT: 49 of 58 [85%] with scores >13.5; 51 of 58 [87%] with scores >13.5) exceeded benchmarks set a priori. Participation in RT was associated with statistically and clinically significant improvement between baseline and postintervention in symptoms of depression (among survivors: -4.0 vs -0.6; difference, -3.4; 95% CI, -5.6 to -1.3; P = .002; among caregivers: -3.8 vs 0.6; difference, -4.5; 95% CI, -6.7 to -2.3; P < .001), anxiety (among survivors: -6.0 vs 0.3; difference, -6.3; 95% CI, -8.8 to -3.8; P < .001; among caregivers: -5.0 vs -0.9; difference, -4.1; 95% CI, -6.7 to -1.5, P = .002), and PTS (among survivors: -11.3 vs 1.0; difference, -12.3; 95% CI, -18.1 to -6.5, P < .001; among caregivers, -11.4 vs 5.0; difference, -16.4, 95% CI, -21.8 to -10.9; P < .001). Improvements sustained through the 12-week follow-up visit. We also observed RT-dependent improvement in dyadic interpersonal interactions for survivors (0.2 vs -0.2; difference, 0.4; 95% CI, 0.0 to 0.8; P = .04). Conclusions and Relevance: In this pilot randomized clinical trial, RT was feasible and potentially efficacious in preventing chronic emotional distress in dyads of survivors of the neuroscience intensive care unit and their informal caregivers. Trial Registration: ClinicalTrials.gov Identifier: NCT03694678.

[Experience of Implementing ABCDEF Bundle Care to Reduce Delirium in a Traumatic Brain Injury Patient].

Patients with traumatic brain injury (TBI) have a high incidence rate of delirium, which leads to poor prognoses. This case study describes a nursing experience of implementing ABCDEF bundle care to reduce delirium in a patient with TBI. The period of nursing care was April 23 to April 30, 2019. A comprehensive assessment of this patient's physical, psychological, familial, social, and spiritual dimensions was conducted via consultation, observation, and physical assessment. The assessment results showed that the patient suffered from acute delirium and cerebral perfusion impairment. In addition, the results showed that the patient's wife suffered from caregiver role strain that was further exacerbated by family difficulties. Multiple, individualized patient-tailored nursing interventions were developed under ABCDEF bundle care to alleviate delirium during the period of nursing care. These interventions included spontaneous awakening trials, spontaneous breathing trials, coordination, delirium assessment, early mobilization, and family engagement. Furthermore, family involvement and interprofessional cooperation with social workers were conducted concurrently to alleviate economic and care burdens and mitigate caregiver role strain in the patient's wife. It is hoped that this nursing care experience helps promote increased attention towards delirium, helps improve early detection of delirium in patients with TBI, and promotes the provision of individualized bundle care that draws on different perspectives in order to achieve holistic health care.

Do spirituality, resilience and hope mediate outcomes among family caregivers after traumatic brain injury or spinal cord injury? A structural equation modelling approach.

BACKGROUND: A deficits approach to understanding psychological adjustment in family caregivers of individuals with a neurological disability is extensive, but further research in the field of positive psychology (spirituality, resilience, hope) may provide a potential avenue for broadening knowledge of the family caregiver experience after traumatic brain injury (TBI) or spinal cord injury (SCI). OBJECTIVE: To test a proposed model of spirituality among family caregivers of individuals with TBI or SCI, using structural equation modelling (SEM). METHODS: A cross-sectional design was employed to survey ninety-nine family participants (TBI = 76, SCI = 23) from six rehabilitation units from NSW and Queensland. Assessments comprised Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale-Expanded, Connor -Davidson Resilience Scale, Herth Hope Index, and three measures of psychological adjustment including Caregiver Burden Scale, Positive and Negative Affect Scale, and Depression Anxiety Stress Scale. RESULTS: SEM showed the proposed model was a good fit. The main findings indicated spirituality had a direct negative link with burden. Spirituality had a direct positive association with hope which, in succession, had a positive link with resilience. Spirituality influenced positive affect indirectly, being mediated by resilience. Positive affect, in turn, had a negative association with depression in caregivers. CONCLUSIONS: This study contributes to better targeting strength-based family interventions.

Can acceptance and commitment therapy facilitate psychological adjustment after a severe traumatic brain injury? A pilot randomized controlled trial.

This study i⁠nvestigated if an Acceptance and Commitment Therapy (ACT) intervention (ACT-Adjust) can facilitate psychological adjustment and reduce psychological distress following severe traumatic brain injury (TBI). The study design comprised a single centre, two-armed, Phase II pilot randomized controlled trial. Nineteen individuals with severe TBI (PTA ≥7 days) who met a clinical threshold for psychological distress (Depression Anxiety Stress Scales-21; DASS > 9) were randomly allocated to either ACT-Adjust (n = 10) or an active control, Befriending Therapy (n = 9), in conjunction with a holistic rehabilitation programme. Primary (psychological flexibility, rehabilitation participation) and secondary (depression, anxiety & stress) outcomes were measured at three-time points (pre, post and follow up). Significant decreases were found for DASS-depression (group by time interaction, F 1,17 = 5.35, p = .03) and DASS-stress (group by time interaction, F 1,17 = 5.69, p = .03) in comparison to the Befriending group, but not for the primary outcome measures. The reduction in stress post-treatment was classed as clinically significant, however interaction differences for stress and depression were not maintained at one month follow up. Preliminary investigations indicate potential for ACT in decreasing psychological distress for individuals with a severe TBI with further sessions required to maintain treatment gains. The pilot results suggest further investigation is warranted in a larger scale clinical trial.

Music Therapy Enhances Executive Functions and Prefrontal Structural Neuroplasticity after Traumatic Brain Injury: Evidence from a Randomized Controlled Trial.

Traumatic brain injury (TBI) causes lifelong cognitive deficits, particularly impairments of executive functioning (EF). Musical training and music-based rehabilitation have been shown to enhance cognitive functioning and neuroplasticity, but the potential rehabilitative effects of music in TBI are still largely unknown. The aim of the present crossover randomized controlled trial (RCT) was to determine the clinical efficacy of music therapy on cognitive functioning in TBI and to explore its neural basis. Using an AB/BA design, 40 patients with moderate or severe TBI were randomized to receive a 3-month neurological music therapy intervention either during the first (AB, n = 20) or second (BA, n = 20) half of a 6-month follow-up period. Neuropsychological and motor testing and magnetic resonance imaging (MRI) were performed at baseline and at the 3-month and 6-month stage. Thirty-nine subjects who participated in baseline measurement were included in an intention-to-treat analysis using multiple imputation. Results showed that general EF (as indicated by the Frontal Assessment Battery [FAB]) and set shifting improved more in the AB group than in the BA group over the first 3-month period and the effect on general EF was maintained in the 6-month follow-up. Voxel-based morphometry (VBM) analysis of the structural MRI data indicated that gray matter volume (GMV) in the right inferior frontal gyrus (IFG) increased significantly in both groups during the intervention versus control period, which also correlated with cognitive improvement in set shifting. These findings suggest that neurological music therapy enhances EF and induces fine-grained neuroanatomical changes in prefrontal areas.

Equine-assisted interventions for veterans with service-related health conditions: a systematic mapping review.

BACKGROUND: Evidence-based treatments for service-related health conditions such as posttraumatic stress disorder (PTSD), depression, and traumatic brain injury (TBI) are not effective for all veterans. Equine-assisted interventions are emerging as an additional treatment modality, but little is known regarding the safe and effective delivery of these interventions. This study aimed to describe the following features of the body of literature concerning equine-assisted interventions among veterans: 1) veterans who have participated in equine-assisted interventions; 2) specific characteristics of equine-assisted interventions in veterans; and 3) the specific characteristics of research on equine-assisted interventions in veterans. METHODS: We conducted a systematic mapping review of peer-reviewed literature reporting on equine-assisted interventions among veterans between 1980 and 2017. Searches of nine databases yielded 3336 unique records, six of which met the inclusion criteria and were reviewed. Data relevant to the study aims were extracted and analyzed. RESULTS: Equine-assisted interventions among veterans disproportionately targeted psychosocial outcomes and yielded promising results. The detailed methods of EAI varied in the reported studies, ranging from communicating with the horse to mounted exercises. There was also great diversity in outcome measurement. The state of theoretical development regarding the mechanisms by which equine-assisted interventions benefit the veteran population is currently underdeveloped. Studies provided insufficient detail with respect to the description of the intervention, reasons for attrition, and the dose-response relationship. CONCLUSIONS: Scientific development of equine-assisted interventions targeting psychosocial outcomes among veterans is warranted to establish their efficacy. Targeted outcomes should be expanded, including outcomes more closely aligned with the nature of polytraumatic injuries. Future research must also emphasize the theoretical development of equine-assisted interventions for veterans and thoroughly describe the participants, components of the intervention, factors contributing to attrition, and optimal dose-response relationships.

Treating Alcohol Use Disorder in U.S. Veterans: The Role of Traumatic Brain Injury.

OBJECTIVE: The authors examined the efficacy of valproate to reduce relapse to heavy drinking among veterans with alcohol use disorder (AUD) and neuropsychiatric comorbidities and whether antecedent traumatic brain injury (TBI) or posttraumatic stress disorder (PTSD) affected treatment response. METHODS: Participants were male veterans 18-60 years old with an AUD and no other substance use besides nicotine or cannabis. Sixty-two patients were randomly assigned to receive either valproate or naltrexone. Participants were evaluated at baseline and followed weekly for 24 weeks. All participants received standardized psychosocial interventions as well as treatment for coexistent psychiatric conditions. RESULTS: During the follow-up period, nine study subjects in the naltrexone group and 14 in the valproate group relapsed to heavy drinking, but the difference did not reach statistical significance. Participants with a history of moderate to severe TBI were more likely to relapse to heavy drinking compared with those with no TBI (hazard ratio=4.834, 95% CI=1.103-21.194, p=0.033). PTSD status did not significantly affect outcome. CONCLUSIONS: Intensive outpatient programs are efficacious alternatives to treat AUD in veterans, although the role of pharmacological treatment is not completely elucidated. Glutamatergic agents appear to be less effective than opiate antagonists to prevent relapse to heavy drinking and to increase cumulative abstinence. Future studies should examine novel pharmacological and nonpharmacological options.

Pulsed Transcranial Red/Near-Infrared Light Therapy Using Light-Emitting Diodes Improves Cerebral Blood Flow and Cognitive Function in Veterans with Chronic Traumatic Brain Injury: A Case Series.

Objective: This study explored the outcome of applying red/near-infrared light therapy using light-emitting diodes (LEDs) pulsed with three different frequencies transcranially to treat traumatic brain injury (TBI) in Veterans. Background: Photobiomodulation therapy (PBMT) using LEDs has been shown to have positive effects on TBI in humans and animal models. Materials and methods: Twelve symptomatic military Veterans diagnosed with chronic TBI >18 months post-trauma received pulsed transcranial PBMT (tPBMT) using two neoprene therapy pads containing 220 infrared and 180 red LEDs, generating a power output of 3.3 W and an average power density of 6.4 mW/cm2 for 20 min, thrice per week over 6 weeks. Outcome measures included standardized neuropsychological test scores and qualitative and quantitative single photon emission computed tomography (SPECT) measures of regional cerebral blood flow (rCBF). Results: Pulsed tPBMT significantly improved neuropsychological scores in 6 of 15 subscales (40.0%; p < 0.05; two tailed). SPECT analysis showed increase in rCBF in 8 of 12 (66.7%) study participants. Quantitative SPECT analysis revealed a significant increase in rCBF in this subgroup of study participants and a significant difference between pre-treatment and post-treatment gamma ray counts per cubic centimeter [t = 3.77, df = 7, p = 0.007, 95% confidence interval (95,543.21-21,931.82)]. This is the first study to report quantitative SPECT analysis of rCBF in regions of interest following pulsed tPBMT with LEDs in TBI. Conclusions: Pulsed tPBMT using LEDs shows promise in improving cognitive function and rCBF several years after TBI. Larger, controlled studies are indicated.
