A Preliminary Examination of Prolonged Exposure Therapy With Iraq and Afghanistan Veterans With a Diagnosis of Posttraumatic Stress Disorder and Mild to Moderate Traumatic Brain Injury

A conceptual framework for a neurophysiological basis of art therapy for PTSD

Post-traumatic stress disorder (PTSD) is a heterogeneous condition that affects many civilians and military service members. Lack of engagement, high dropout rate, and variable response to psychotherapy necessitates more compelling and accessible treatment options that are based on sound neuroscientific evidence-informed decision-making. Art therapy incorporates elements proven to be effective in psychotherapy, such as exposure, making it a potentially valuable treatment option. This conceptual paper aims to inform the neurophysiological rationale for the use of art therapy as a therapeutic approach for individuals with PTSD. A narrative synthesis was conducted using literature review of empirical research on the neurophysiological effects of art therapy, with supporting literature on neuroaesthetics and psychotherapies to identify art therapy factors most pertinent for PTSD. Findings were synthesized through a proposed framework based on the triple network model considering the network-based dysfunctions due to PTSD. Art therapy's active components, such as concretization and metaphor, active art engagement, emotion processing and regulation, perspective taking and reframing, and therapeutic alliance, may improve symptoms of PTSD and prompt adaptive brain functioning. Given the scarcity of rigorous studies on art therapy's effectiveness and mechanisms of alleviating PTSD symptoms, the suggested framework offers a neurophysiological rationale and a future research agenda to investigate the impact of art therapy as a therapeutic approach for individuals with PTSD.

Disturbances in fear extinction learning after mild traumatic brain injury in mice are accompanied by alterations in dendritic plasticity in the medial prefrontal cortex and basolateral nucleus of the amygdala

Mild traumatic brain injury (mTBI) and post-traumatic stress disorder (PTSD) have emerged as the signature injuries of the U.S. veterans who served in Iraq and Afghanistan, and frequently co-occur in both military and civilian and populations. To better understand how fear learning and underlying neural systems might be altered after mTBI we examined the acquisition of cued fear conditioning and its extinction along with brain morphology and dendritic plasticity in a mouse model of mTBI. To induce mTBI in adult male C57BL/6J mice, a lateral fluid percussive injury (LFP 1.7) was produced using a fluid pulse of 1.7 atmosphere force to the right parietal lobe. Behavior in LFP 1.7 mice was compared to behavior in mice from two separate control groups: mice subjected to craniotomy without LFP injury (Sham) and mice that did not undergo surgery (Unoperated). Following behavioral testing, neural endpoints (dendritic structural plasticity and neuronal volume) were assessed in the basolateral nucleus of the amygdala (BLA), which plays a critical sensory role in fear learning, and medial prefrontal cortex (mPFC), responsible for executive functions and inhibition of fear behaviors. No gross motor abnormalities or increased anxiety-like behaviors were observed in LFP or Sham mice after surgery compared to Unoperated mice. We found that all mice acquired fear behavior, assessed as conditioned freezing to auditory cue in a single session of 6 trials, and acquisition was similar across treatment groups. Using a linear mixed effects analysis, we showed that fear behavior decreased overall over 6 days of extinction training with no effect of treatment group across extinction days. However, a significant interaction was demonstrated between the treatment groups during within-session freezing behavior (5 trials per day) during extinction training. Specifically, freezing behavior increased across within-session extinction trials in LFP 1.7 mice, whereas freezing behavior in control groups did not change on extinction test days, reflecting a dissociation between within-trial and between-trial fear extinction. Additionally, LFP mice demonstrated bilateral increases in dendritic spine density in the BLA and decreases in dendritic complexity in the PFC. The translational implications are that individuals with TBI undergoing fear extinction therapy may demonstrate within-session aberrant learning that could be targeted for more effective treatment interventions.

The impact of prior head injury on outcomes following group and individual cognitive processing therapy among military personnel

This study examined the impact of a history of head injury (HHI) on posttraumatic stress disorder (PTSD) and depression symptoms in active duty military personnel following group and individual cognitive processing therapy (CPT). Data for these secondary analyses were drawn from a clinical trial comparing group and individual CPT. Service members (N = 268, 91.0% male) were randomized to 12 sessions of group (n = 133) or individual (n = 135) CPT. Most participants (57.1%) endorsed a deployment-related HHI, 92.8% of whom reported currently experiencing symptoms (CES) related to the head injury (i.e., HHI/CES). Patients classified as non-HHI/CES demonstrated large, significant improvements in PTSD symptom severity in both individual and group therapy, ds = 1.1, p < .001. Patients with HHI/CES status showed similar significant improvements when randomized to individual CPT, d = 1.4, p < .001, but did not demonstrate significant improvements when randomized to group CPT, d = 0.4, p = .060. For participants classified as HHI/CES, individual CPT was significantly superior to group CPT, d = 0.98, p = .003. Symptoms of depression improved following treatment, with no significant differences by treatment delivery format or HHI/CES status. The findings of this clinical trial subgroup study demonstrate evidence that group CPT is less effective than individual CPT for service members classified as HHI/CES. The results suggest that HHI/CES status may be important to consider in selecting patients for group or individual CPT; additional research is needed to confirm the clinical implications of these findings.

Risk Factors for High Symptom Burden Three Months after Traumatic Brain Injury and Implications for Clinical Trial Design: A Transforming Research and Clinical Knowledge in Traumatic Brain Injury Study

More than 75% of patients presenting to level I trauma centers in the United States with suspicion of TBI sufficient to require a clinical computed tomography scan report injury-related symptoms 3 months later. There are currently no approved treatments, and few clinical trials have evaluated possible treatments. Efficient trials will require subject inclusion and exclusion criteria that balance cost-effective recruitment with enrolling individuals with a higher chance of benefiting from the interventions. Using data from the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) study, we examined the relationship of 3-month symptoms to pre-injury, demographic, and acute characteristics as well as 2-week symptoms and blood-based biomarkers to identify and evaluate factors that may be used for sample enrichment for clinical trials. Many of the risk factors for TBI symptoms reported in the literature were supported, but the effect sizes of each were small or moderate (< 0.5). The only factors with large effect sizes when predicting 3-month symptom burden were TBI-related (i.e., post-concussive) and post-traumatic stress symptom levels at 2 weeks (respective effect sizes 1.13 and 1.34). TBI severity was not significantly associated with 3-month symptom burden (p = 0.37). Using simulated data to evaluate the effect of enrichment, we showed that including only people with high symptom burden at 2 weeks would permit trials to reduce the sample size by half, with minimal increase in screening, as compared with enrolling an unenriched sample. Clinical trials aimed at reducing symptoms after TBI can be efficiently conducted by enriching the included sample with people reporting a high early symptom burden.

A comparison of prolonged exposure therapy, pharmacotherapy, and their combination for PTSD: What works best and for whom; study protocol for a randomized trial

BACKGROUND

Several efficacious psychological and pharmacological treatments for posttraumatic stress disorder (PTSD) are available; however, the comparative effectiveness of these treatments represents a major gap in the literature. The proposed study will compare the effectiveness of two leading PTSD treatments - Prolonged Exposure (PE) therapy and pharmacotherapy with paroxetine or venlafaxine extended release - as well as the combination of PE and medication.

METHODS

In a randomized clinical trial, veterans with PTSD (N = 450) recruited across six Veterans Affairs Medical Centers will complete assessments at baseline, mid-treatment (Week 7), post-treatment (Week 14), and follow-up (Weeks 27 and 40). The primary outcome will be change in (both clinician-rated and self-reported) PTSD severity. Depression symptoms, quality of life, and functioning will also be measured and examined as secondary outcomes. Baseline demographic and clinical data will be used to develop "personalized advantage indices" (PAIs), with the goal of identifying who is most likely to benefit from which treatment.

CONCLUSIONS

This planned trial will yield findings to directly inform clinical practice guidelines for PTSD, by providing comparative effectiveness data to support recommendations about what can be considered the "first-line" treatment option(s) for PTSD. Further, findings from this trial have the potential to guide treatment planning for individual patients, through implementation of PAIs developed from study data, in service of "personalized medicine."

Evaluation of post-traumatic stress disorder (PTSD) and related comorbidities in clinical studies

Patients with traumatic brain injury (TBI) of varying severities are experiencing adverse outcomes during and after rehabilitation. Besides depression and anxiety, post-traumatic stress disorder (PTSD) is highly encountered in civilian and military populations. As more prospective and retrospective studies - focused on evaluating new or old psychological therapies in inpatient, outpatient, or controlled environments, targeting patients with PTSD with or without a history of TBI - are carried out, researchers are employing various scales to measure PTSD as well as other psychiatric diagnoses or cognitive impairments that might appear following TBI. We aimed to explore the literature published between January 2010 and October 2021 by querying three databases. Our preliminary results showed that several scales - such as the Clinician-Administered PTSD Scale (CAPS), the Posttraumatic Stress Disorder Checklist Military Version (PCL-M) as well as Specific Version (PCL-S), and Civilian Version (PCL-C) - have been frequently used for PTSD diagnosis and symptom severity. However, heterogeneity in the scales used when assessing and evaluating additional psychiatric comorbidities and cognitive impairments are due to the study aim and therapeutic approaches. Therefore, conducting an intervention focusing on post-TBI PTSD patients requires increased attention to patients' medical history in capturing multiple cognitive impairments and affected neuropsychological processes when designing the study and including validated instruments for measuring primary and secondary neuropsychological outcomes.

Emotion Dysregulation Following Trauma: Shared Neurocircuitry of Traumatic Brain Injury and Trauma-Related Psychiatric Disorders

The psychological trauma associated with events resulting in traumatic brain injury (TBI) is an important and frequently overlooked factor that may impede brain recovery and worsen mental health following TBI. Indeed, individuals with comorbid posttraumatic stress disorder (PTSD) and TBI have significantly poorer clinical outcomes than individuals with a sole diagnosis. Emotion dysregulation is a common factor leading to poor cognitive and affective outcomes following TBI. Here, we synthesize how acute postinjury molecular processes stemming from either physical or emotional trauma may adversely impact circuitry subserving emotion regulation and ultimately yield long-term system-level functional and structural changes that are common to TBI and PTSD. In the immediate aftermath of traumatic injury, glucocorticoids stimulate excess glutamatergic activity, particularly in prefrontal cortex-subcortical circuitry implicated in emotion regulation. In human neuroimaging work, assessing this same circuitry well after the acute injury, TBI and PTSD show similar impacts on prefrontal and subcortical connectivity and activation. These neural profiles indicate that emotion regulation may be a useful target for treatment and early intervention to prevent the adverse sequelae of TBI. Ultimately, the success of future TBI and PTSD early interventions depends on the fields' ability to address both the physical and emotional impact of physical injury.

Improvement in executive functioning after Goal-Oriented Attentional Self-Regulation training is associated with reduction in PTSD hyperarousal symptoms among veterans with comorbid PTSD and mild TBI

Goal-Oriented Attentional Self-Regulation (GOALS) is a cognitive rehabilitation training program that combines mindfulness-based attention regulation with individualized goal management strategies to improve functioning in daily life after traumatic brain injury (TBI). While not a specific target of GOALS training, previous research has indicated improvements in emotional functioning following GOALS training, specifically symptoms related to depression and posttraumatic stress disorder (PTSD). The current study is based on the hypothesis that improvements in cognitive control processes related to executive functioning and attention after GOALS training generalize to improvements in emotional functioning, thereby resulting in reductions in emotional distress. The current study analyzed archival data from 33 Veteran participants with a confirmed diagnosis of PTSD and a history of mild TBI who received either GOALS training or a psychoeducational intervention matched for time, therapist attention, and participation format. Regression analysis was used to assess the strength of the relationship between improvements in Overall Attention/Executive Functioning and decreases in hyperarousal symptoms associated with PTSD. Results from the regression analysis revealed that improvements in Overall Attention/Executive Functioning after GOALS was significantly associated with reductions in hyperarousal symptoms associated with PTSD (R² = 0.26, F_(1,15) = 5.01, β = -.51, p < .05). The current findings suggest that cognitive improvements after GOALS training may lead to changes in emotional functioning, resulting in decreased emotional distress. This is important, particularly in VA settings, because the results potentially highlight additional areas of research and focus on the treatment of comorbid mild TBI and PTSD among Veterans.

The efficacy of written exposure therapy versus imaginal exposure delivered online for posttraumatic stress disorder: Design of a randomized controlled trial in Veterans

Adapting evidence-based treatments for online delivery has potential to significantly increase the reach of effective care to Veterans with posttraumatic stress disorder (PTSD). This paper describes the rationale for and methods of a randomized controlled trial comparing the efficacy and efficiency of written exposure therapy versus imaginal exposure for PTSD delivered in a novel online and variable length format. Participants will be 300 Veterans seeking treatment for clinically significant symptoms of PTSD. Participants will be randomly assigned to either written exposure or imaginal exposure via verbal recounting and will complete between 4 and 8 online therapy sessions facilitated by trained peer support specialists. Treatment is terminated before session 8 if the PTSD symptom improvement criterion is met. Assessments will be conducted at baseline, post-treatment, and at 3-month follow-up. The primary hypotheses are that written exposure therapy will be noninferior to imaginal exposure with respect to treatment efficacy and efficiency. Secondary hypotheses relate to identifying and comparing potential mediators of PTSD treatment outcome, including trauma-related cognitions and emotion regulation.

Cognitive Impairment and Predicting Response to Treatment in an Intensive Clinical Program for Post-9/11 Veterans With Posttraumatic Stress Disorder

OBJECTIVE

This study examined whether objectively measured pretreatment cognitive impairment predicted worse response to treatment for posttraumatic stress disorder. Participants were 113 veterans and active duty service members who participated in a new multidisciplinary 2-week intensive clinical program that included individual trauma-focused cognitive-behavioral therapy, group psychotherapy, psychoeducation, skills-building groups, and complementary and alternative medicine treatments (mean age: 39.7 years [SD=8.5]; 20% women).

METHODS

Prior to treatment, participants completed a brief computerized cognitive battery (CNS Vital Signs) and were operationalized as having cognitive impairment if they scored in the ≤5th percentile on two or more of five core cognitive domains. Participants completed measures of traumatic stress, depression, cognitive self-efficacy, and satisfaction with their ability to participate in social roles before and after treatment.

RESULTS

There were no significant correlations between pretreatment individual cognitive test scores and change in the clinical outcome measures. One-half of the study sample (49.6%) met criteria for cognitive impairment. In a mixed multivariate analysis of variance, the interaction between cognitive impairment and time was not significant (F=0.83, df=4, 108, p=0.51), indicating that the pre- to posttreatment changes in outcome scores were not significantly different for the cognitively impaired group compared with the cognitively intact group. The multivariate main effect for time was significant (F=36.75, df=4, 108, p<0.001). Follow-up univariate tests revealed significant improvement in traumatic stress, depression, cognitive self-efficacy, and satisfaction with social roles after treatment.

CONCLUSIONS

Cognitive impairment was not associated with worse response to treatment in veterans with severe and complex mental health problems. Veterans with and without cognitive impairment reported large improvements in symptoms and functioning after treatment.

An Update on the Complexity and Importance of Accurately Diagnosing Post-Traumatic Stress Disorder and Comorbid Traumatic Brain Injury

As awareness for diagnosing and screening patients for trauma has grown, more effective evidence-based treatments are available to treat post-traumatic stress disorder (PTSD). Despite these gains, several patients are non-responsive to care and research has shifted to determining barriers for cure or improvement. With the advent of modern warfare, the combination of intermittent explosive devices and more robust armor has resulted in service members surviving blasts that historically would have been lethal, resulting in a rise in traumatic brain injuries (TBIs). Post-traumatic stress disorder and TBI are often comorbid and can serve as the aforementioned barriers for cure or improvement for each other if one goes unrecognized. This mini-review will discuss the importance of diagnosing both entities, especially when they are comorbid, by examining how misdiagnosis may interfere with treatment outcomes. Several recent advances in methods to successfully distinguish between the two disorders will be reviewed.

Baseline Cognitive Performance and Treatment Outcomes From Cognitive-Behavioral Therapies for Posttraumatic Stress Disorder: A Naturalistic Study

OBJECTIVE

Approximately 5%-20% of U.S. troops returning from Iraq and Afghanistan have posttraumatic stress disorder (PTSD), and another 11%-23% have traumatic brain injury (TBI). Cognitive-behavioral therapies (CBTs) are empirically validated treatment strategies for PTSD. However, cognitive limitations may interfere with an individual's ability to adhere to as well as benefit from such therapies. Comorbid TBI has not been systematically taken into consideration in PTSD outcome research or in treatment planning guidance. The authors hypothesized that poorer pretreatment cognitive abilities would be associated with poorer treatment outcomes from CBTs for PTSD.

METHODS

This study was designed as a naturalistic examination of treatment as usual in an outpatient clinic that provides manualized CBTs for PTSD to military service members and veterans. Participants were 23 veterans, aged 18-50 years, with combat-related PTSD and a symptom duration of more than 1 year. Of these, 16 participants had mild TBI (mTBI). Predictor variables were well-normed objective tests of cognitive ability measured at baseline. Outcome variables were individual slopes of change of the PTSD Checklist for DSM-5 (PCL-5) and the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) over weeks of treatment, and of pretreatment-to-posttreatment change in PCL-5 and CAPS-5 (ΔPCL-5 and ΔCAPS-5, respectively).

RESULTS

Contrary to prediction, neither pretreatment cognitive performance nor the presence of comorbid mTBI predicted poorer response to CBTs for PTSD.

CONCLUSIONS

These results discourage any notion of excluding patients with PTSD and poorer cognitive ability from CBTs.

Treatment for posttraumatic stress disorder in patients with a history of traumatic brain injury: A systematic review

Posttraumatic stress disorder (PTSD) frequently co-occurs with traumatic brain injury (TBI). We conducted a systematic review to evaluate the appropriateness and effectiveness of treatments for PTSD in adult patients with a history of TBI. We searched for longitudinal studies aimed at treatments for PTSD patients who sustained a TBI, published in English between 1980 and February 2019. Twenty-three studies were found eligible, and 26 case studies were included for a separate overview. The quality of eligible studies was assessed using the Research Triangle Institute item bank. The majority of studies included types of cognitive-behavioral therapy (CBT) in male service members and veterans with a history of mild TBI in the United States. Studies using prolonged exposure (PE), cognitive-processing therapy (CPT) or other types of CBT, usually in combination with additional treatments, showed favorable outcomes. A smaller number of studies described complementary and novel therapies, which showed promising results. Overall, the quality of studies was considered low. We concluded that CBT seem appropriate for the patient population with history of TBI. The evidence is less strong for other therapies. We recommend controlled studies of PTSD treatments including more female patients and those with a history of moderate to severe TBIs in civilian and military populations.

Effectiveness and harms of mental health treatments in service members and veterans with deployment-related mild traumatic brain injury

BACKGROUND

Co-morbidity of psychiatric conditions with traumatic brain injury (TBI) is common among service members and Veterans from recent deployments. Practice guidelines for mild TBI (mTBI) recommend management of co-occurring psychiatric conditions with existing treatments, but it is unclear whether the effectiveness of treatments for psychiatric conditions is impacted by mTBI. We conducted a systematic literature review to examine the effectiveness and harms of pharmacological and non-pharmacological treatments for posttraumatic stress disorder, depressive disorders, substance use disorders, suicidal ideation or attempts, and anxiety disorders in the presence of co-morbid deployment-related mTBI.

METHODS

We searched bibliographic databases for peer-reviewed, English language studies published from 2000 to October 2017. Two reviewers independently completed abstract triage and full text review.

RESULTS

We identified 7 studies (5 pre-post and 2 secondary analysis). Six assessed psychotherapy and one reported on hyperbaric oxygen therapy (HBO₂). Studies comparing outcomes by TBI history found that a history of TBI does not affect treatment outcomes. Harms were reported only for HBO₂ and were mild. No study examined the effectiveness of treatments for substance use disorders or suicidal ideation, or the effectiveness of pharmacological interventions for the psychiatric conditions of interest in service members and Veterans with mTBI.

LIMITATIONS

Studies lacked usual care or wait-list control groups and no randomized trials were found, making the strength of evidence insufficient.

CONCLUSIONS

Evidence is insufficient to fully assess the impact of TBI on the effectiveness of treatments for psychiatric conditions. Higher quality evidence with definitive guidance for providers treating this population is needed.

Psychological Intervention in Traumatic Brain Injury Patients

Objective

To provide a brief and comprehensive summary of recent research regarding psychological interventions for patients surviving a traumatic brain injury.

Methods

A bibliographical search was performed in PubMed, Cochrane Library, PsycNET, Scopus, ResearchGate, and Google Scholar online databases. Analysis included distribution by year of publication, age stage of participants (paediatric, adult), location of the research team, study design, type of intervention, and main outcome variables.

Results

The initial search eliciting 1541 citations was reduced to 62 relevant papers. Most publications had adult samples (88.7%). The United States outstands as the country with more research (58.1%); Latin America countries provided no results. Cognitive behavioural therapy (CBT) was the most widely used approach for treatment of (sub)clinical mental disturbances (41.9%). Neuropsychological interventions were scarce (4.8%). Outcome measures included psychiatric disorders (e.g., posttraumatic stress disorder (PTSD), depression, and anxiety) (37.1%), postconcussive symptoms (16.1%), cognitive and functional deficits (48.1%), and social and psychological dimensions (62.9%).

Conclusions

CBT outstands as the preferred therapeutic approach for treating behavioural and emotional disturbances. Also, other related therapies such as dialectical behaviour, mindfulness, and acceptance and commitment therapies have been proposed, and probably in the years to come, more literature regarding their effectiveness will be available. On the other hand, evidence showed that interventions from the field of neuropsychology are minimal if compared with its contribution to assessment. Future research should be aimed at performing studies on more diverse populations (e.g., nonmilitary communities and paediatric and Latin American populations) and at controlling designs to examine the therapeutic efficacy of psychotherapeutic and neurocognitive rehabilitation interventions and compare amelioration by injury severity, age of patients, and clinical profile, in the hopes of creating better guidelines for practitioners.

Psychotherapy for PTSD: An evidence-based guide to a theranostic approach to treatment

Posttraumatic stress disorder (PTSD) is often a clinically complex disorder, frequently presenting with comorbid clinical conditions. Individuals with PTSD may also present with high-risk symptoms such as substance misuse and suicidal ideation. The clinical complexity of PTSD has precluded some clinicians from providing gold-standard trauma-focused treatment due to concern of iatrogenic effects. However, evidence to date suggests that trauma-focused treatments are safe and effective for PTSD even when higher-risk comorbidity presents. Occasionally, while some patients present with clinical concerns that may benefit from modifications to standard recommended treatment protocols, research suggests there are few absolute contraindications to trauma-focused treatment. The present manuscript provides a review of evidence-based assessment and treatment recommendations for PTSD. A clinical decision-making guide for PTSD across areas of clinical complexity is provided.

Neurobehavioral Management of the Polytrauma Veteran

Since the inception of the Afghanistan and Iraq wars, an increasing number of veterans have sought treatment from the Department of Veterans Affairs for combat-related injuries. Many veterans experience postconcussive symptoms, traumatic stress, chronic pain, sensory deficits, and/or headaches. The goal of this article was to highlight some of the challenges treatment providers may face, while providing rehabilitation specialists with important evaluation and treatment considerations in working with this population to maximize outcomes for these veterans.

Chronic Pain, TBI, and PTSD in Military Veterans: A Link to Suicidal Ideation and Violent Impulses?

The polytrauma clinical triad refers to the co-occurrence of chronic pain, traumatic brain injury (TBI), and posttraumatic stress disorder (PTSD). Despite research implicating dyadic relationships between these conditions and adverse outcomes, scant research has examined the polytrauma clinical triad's relation to suicide or violence. The present cross-sectional study was designed to examine whether this complex clinical presentation increases risk of suicidal ideation and violent impulses after accounting for other established risk factors. Veterans who served in the military since September 11, 2001 (N = 667) who reported chronic pain completed an interview and self-report battery. Bivariate analyses showed that suicidal ideation and violent impulses both correlated with PTSD, TBI+PTSD, pain intensity and interference, drug abuse, and major depressive disorder (MDD). Multiple regression analyses showed that: 1) race, chronic pain with PTSD, alcohol abuse, and MDD significantly predicted suicidal ideation, 2) pain interference, chronic pain with TBI, chronic pain with PTSD, chronic pain with TBI+PTSD, drug abuse, and MDD significantly predicted violent impulses, and 3) pain interference was a more critical predictor of suicidal and violent ideation than pain intensity. Implications for risk assessment and treatment are discussed.

PERSPECTIVE

This article presents results from a study examining predictors of suicide and violence risk among a sample of post-9/11 U.S. Veterans with chronic pain. Health care professionals should assess for pain interference, TBI, PTSD, depression, and alcohol/drug abuse when conducting risk assessments with this population.

Does Traumatic Brain Injury Attenuate the Exposure Therapy Process?

Research indicates that exposure therapy is efficacious for combat-related posttraumatic stress disorder (PTSD) comorbid with traumatic brain injury (TBI) as is shown by reduced PTSD treatment outcome scores. What is unknown, however, is whether the process of fear extinction is attenuated in veterans with TBI history. Increased PTSD symptomatology and possible cognitive deficits associated with TBI sequelae may indicate additional or longer exposure sessions to achieve habituation and extinction comparable to individuals without TBI history. As such, a more extensive course of treatment may be necessary to achieve comparable PTSD treatment outcome scores for individuals with TBI history. Using a sample of veterans with combat-related PTSD, some of whom were comorbid for TBI, this study compared process variables considered relevant to successful treatment outcome in exposure therapy. Individuals with and without TBI demonstrated similar rates of fear activation, length and number of exposure sessions, within-session habituation, between-session habituation, and extinction rate; results remained consistent when controlling for differential PTSD symptomatology. Furthermore, results indicated that self-perception of executive dysfunction did not impact the exposure process. Results suggest that individuals with PTSD and TBI history engage successfully and no differently in the exposure therapy process as compared to individuals with PTSD alone. Findings further support exposure therapy as a first-line treatment for combat-related PTSD regardless of TBI history.

A Review of Studies on the System-Wide Implementation of Evidence-Based Psychotherapies for Posttraumatic Stress Disorder in the Veterans Health Administration

Since 2006, the Veterans Health Administration (VHA) has instituted policy changes and training programs to support system-wide implementation of two evidence-based psychotherapies (EBPs) for posttraumatic stress disorder (PTSD). To assess lessons learned from this unprecedented effort, we used PubMed and the PILOTS databases and networking with researchers to identify 32 reports on contextual influences on implementation or sustainment of EBPs for PTSD in VHA settings. Findings were initially organized using the exploration, planning, implementation, and sustainment framework (EPIS; Aarons et al. in Adm Policy Ment Health Health Serv Res 38:4-23, 2011). Results that could not be adequately captured within the EPIS framework, such as implementation outcomes and adopter beliefs about the innovation, were coded using constructs from the reach, effectiveness, adoption, implementation, maintenance (RE-AIM) framework (Glasgow et al. in Am J Public Health 89:1322-1327, 1999) and Consolidated Framework for Implementation Research (CFIR; Damschroder et al. in Implement Sci 4(1):50, 2009). We highlight key areas of progress in implementation, identify continuing challenges and research questions, and discuss implications for future efforts to promote EBPs in large health care systems.

Evidence-based Treatments for Military-related Posttraumatic Stress Disorder in a Veterans Affairs Setting

Posttraumatic stress disorder (PTSD) can have a significant negative impact on the physical, emotional, and mental health of individuals. This article discusses the prevalence, risk factors, and diagnostic criteria for PTSD. Given the high incidence of PTSD in the Veteran population, much attention has been given to assessment and treatment issues. Treatment options for PTSD, including the 2 most effective treatments, prolonged exposure and cognitive processing therapy, are discussed. Special issues concerning the treatment of Veterans are also reviewed.

A non-inferiority trial of Prolonged Exposure for posttraumatic stress disorder: In person versus home-based telehealth

This is the first randomized controlled trial to evaluate non-inferiority of Prolonged Exposure (PE) delivered via home-based telehealth (HBT) compared to standard in-person (IP) PE. One-hundred thirty two Veterans recruited from a Southeastern Veterans Affairs Medical Center and affiliated University who met criteria for posttraumatic stress disorder (PTSD) were randomized to receive PE via HBT or PE via IP. Results indicated that PE-HBT was non-inferior to PE-IP in terms of reducing PTSD scores at post-treatment, 3 and 6 month follow-up. However, non-inferiority hypotheses for depression were only supported at 6 month follow-up. HBT has great potential to reduce patient burden associated with receiving treatment in terms of travel time, travel cost, lost work, and stigma without sacrificing efficacy. These findings indicate that telehealth treatment delivered directly into patients' homes may dramatically increase the reach of this evidence-based therapy for PTSD without diminishing effectiveness.

Effectiveness of Prolonged Exposure and Cognitive Processing Therapy for U.S. Veterans With a History of Traumatic Brain Injury

This retrospective analysis of previously existing nonrandomized clinical data examined the effectiveness of completing prolonged exposure (PE) or cognitive processing therapy (CPT) in a sample of 41 U.S. veterans at a Veterans Affairs medical center. The sample included 19 veterans with diagnoses of posttraumatic stress disorder (PTSD) and traumatic brain injury (TBI) and 22 veterans with PTSD only. Diagnostic groups did not significantly differ on PTSD and depression symptom reduction, F(2, 36) = 0.05, p = .951; Pillai's trace = 0.00, partial η² = .00. Veterans who completed PE showed greater symptom reduction than those who completed CPT, F(2, 36) = 12.10, p < .001; Pillai's trace = 0.40, partial η² = .40, regardless of TBI status. Overall, our results suggested that TBI status should not preclude individuals from being offered trauma-focused PTSD treatment.

Treatment of persistent post-concussive symptoms after mild traumatic brain injury: a systematic review of cognitive rehabilitation and behavioral health interventions in military service members and veterans

Increased prevalence of traumatic brain injury (TBI) has been associated with service members and veterans who completed combat deployments in support of Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF). Management of persistent post-concussive symptoms (PCS) has been a challenge to healthcare providers throughout the Military and Veterans Healthcare Systems, as well as civilian healthcare providers, due in part to the chronic nature of symptoms, co-occurrence of behavioral health disorders such as depression, Posttraumatic Stress Disorder (PTSD), and substance use disorders, and fear of a potential stigma associated with psychiatric diagnoses and behavioral health treatment(s). This systematic review examined non-pharmacologic behavioral health interventions and cognitive rehabilitation interventions for PCS in military service members and veterans with a history of mild TBI (mTBI). Six electronic databases were searched with specific term limitations, identifying 121 citations. Ultimately, 19 articles met criteria for inclusion in this systematic review. Studies were broadly categorized into four subtypes: psychoeducational interventions, cognitive rehabilitation, psychotherapeutic approaches, and integrated behavioral health interventions for PCS and PTSD. The review provides an update of the empirical evidence for these four types of interventions for PCS in active duty service members and veterans. Recommendations for future research are discussed, including the need to expand and improve the limited evidence basis on how to manage persistent post-concussive symptoms in this population.

Assessing for mild TBI among Iraq and Afghanistan veterans: Outcomes of injury severity and neurological factors

OBJECTIVE

To investigate injury severity markers and neurological symptoms associated with clinician-confirmed mild traumatic brain injury (TBI) among Iraq and Afghanistan veterans.

SETTING

Department of Veterans Affairs (VA) medical centre and five affiliated community-based outpatient clinics.

PARTICIPANTS

Three hundred and fifty Iraq and Afghanistan veterans with positive initial VA TBI screens between 1 April 2007 and 1 June 2010 and clinician-confirmed TBI status by 1 December 2010.

METHODS

Retrospective-cohort study of medical record data. Main measures included clinician-confirmed TBI status, injury severity markers (e.g. loss of consciousness (LOC), post-traumatic amnesia (PTA) or confusion/disorientation) and neurological symptoms.

RESULTS

Among veterans who screened positive on the initial VA TBI and then received a clinician evaluation, 60% were confirmed to have a TBI diagnosis. Veterans reporting at least one LOC, confusion or PTA were almost 18-times more likely to receive a confirmed TBI diagnosis. Odds of clinician-confirmed TBI were 2.5-3-times greater among those who endorsed dizziness, poor coordination, headaches, nausea, vision problems and/or irritability, compared to those not endorsing these symptoms. Nausea had greatest utility for confirming a TBI.

CONCLUSIONS

Identification of neurologic symptoms that most contribute to a clinician-confirmed diagnosis of TBI has potential for streamlining detection of TBI and symptoms needed for treatment.

Prolonged Exposure Therapy With Veterans and Active Duty Personnel Diagnosed With PTSD and Traumatic Brain Injury

The present study used archival clinical data to analyze the delivery and effectiveness of prolonged exposure (PE) and ancillary services for posttraumatic stress disorder (PTSD) among Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn veterans (N = 69) with histories of mild to severe traumatic brain injury (TBI). Data from standard clinical assessments of veterans and active duty personnel treated in both inpatient and outpatient programs at 2 Department of Veteran Affairs medical centers were examined. Symptoms were assessed with self-report measures of PTSD (PTSD Checklist) and depression (Beck Depression Inventory-II) before and throughout therapy. Mixed linear models were utilized to determine the slope of reported symptoms throughout treatment, and the effects associated with fixed factors such as site, treatment setting (residential vs. outpatient), and TBI severity were examined. Results demonstrated significant decreases in PTSD, B = -3.00, 95% CI [-3.22, -2.78]; t(210) = -13.5; p < .001, and in depressive symptoms, B = -1.46, 95% CI [-1.64, -1.28]; t(192) = -8.32; p < .001. The effects of PE treatment did not differ by clinical setting and participants with moderate to severe injuries reported more rapid gains than those with a history of mild TBI. The results provide evidence that PE may well be effective for veterans with PTSD and TBI.

PTSD and TBI co-morbidity: scope, clinical presentation and treatment options

PRIMARY OBJECTIVE

To summarize the literature on post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI) and their co-morbidity, focusing on diagnosis, clinical symptoms and treatment issues relevant to the clinician.

RESEARCH DESIGN

Review of the literature.

METHODS AND PROCEDURES

Pubmed searches were performed using the terms post-traumatic stress disorder, traumatic brain injury, sleep, cognitive, depression, anxiety, treatment and combinations of these terms. Those articles relevant to the objective were included.

MAIN OUTCOMES AND RESULTS

This study presents pathophysiological, neuroimaging and clinical data on co-morbid PTSD and TBI. It reviews associated conditions, emphasizing the impact of cognitive and sleep problems. It summarizes the emerging literature on treatment effectiveness for co-morbid PTSD and TBI, including psychotherapy, pharmacotherapy and cognitive rehabilitation.

CONCLUSIONS

Both PTSD and TBI commonly occur in the general population, both share some pathophysiological characteristics and both are associated with cognitive impairment and sleep disruption. PTSD and TBI present with a number of overlapping symptoms, which can lead to over-diagnosis or misdiagnosis. Both conditions are associated with co-morbidities important in diagnosis and treatment planning. More research is needed to elucidate what treatments are effective in PTSD and TBI co-morbidity and on factors predictive of treatment success.

A comparison of Narrative Exposure Therapy and Prolonged Exposure therapy for PTSD

The purpose of this review was to compare and contrast Prolonged Exposure (PE) and Narrative Exposure Therapy (NET). We examined the treatment manuals to describe the theoretical foundation, treatment components, and procedures, including the type, manner, and focus of exposure techniques and recording methods used. We examined extant clinical trials to investigate the range of treatment formats reported, populations studied, and clinical outcome data. Our search resulted in 32 studies on PE and 15 studies on NET. Consistent with prior reviews of PTSD treatment, it is evident that PE has a solid evidence base and its current status as a first line treatment for the populations studied to this date is warranted. We argue that NET may have advantages in treating complex traumatization seen in asylum seekers and refugees, and for this population NET should be considered a recommended treatment. NET and PE have several commonalities, and it is recommended that studies of these treatments include a broader range of populations and trauma types to expand the current knowledge on the treatment of PTSD.

Traumatic brain injury and posttraumatic stress disorder

Given the upsurge of research in posttraumatic stress disorder (PTSD) and traumatic brain injury (TBI), much of which has focused on military samples who served in Iraq and Afghanistan, the purpose of this article is to review the literature published after September 11th, 2001 that addresses the epidemiology, pathophysiology, evaluation, and treatment of PTSD in the context of TBI.

PTSD in active combat soldiers: to treat or not to treat

In this paper, we consider ethical issues related to the treatment of posttraumatic stress disorder (PTSD) in combat zones, via exposure therapy. Exposure-oriented interventions are the most well-researched behavioral treatments for PTSD, and rigorous studies across contexts, populations, and research groups provide robust evidence that exposure therapy for PTSD is effective and can be widely disseminated. Clinical procedures for Prolonged Exposure therapy, a manualized exposure-oriented protocol for PTSD, are reviewed, and we illustrate the potential benefits, as well as the potential difficulties, associated with providing this treatment in combat zones. Several ethical considerations are identified: (1) Assuming successful treatment, is it ethical to send individuals with a known risk of developing PTSD back into combat? (2) If treatment is unsuccessful in theater (perhaps due to the confounding factor of ongoing danger), could that impact treatment effectiveness for soldiers who attempt therapy again post-deployment? (3) If the military finds combat-zone treatment effective and useful in maintaining an efficient work force, will treatment become mandatory for those diagnosed with PTSD? (4) What unintended consequences might be associated with large-scale dissemination of exposure therapy in or near combat, outside of mental health care infrastructures? (5) How would genetic variations known to be associated with PTSD risk influence decisions regarding who receives treatment or returns to combat? We conclude with a review of the personal and societal costs associated with not providing evidence-based PTSD treatments wherever possible.

Enhancing exposure therapy for PTSD with yohimbine HCL: protocol for a double-blind, randomized controlled study implementing subjective and objective measures of treatment outcome

Prolonged exposure (PE) therapy is considered a gold standard protocol for the treatment of PTSD, and it is associated with large treatment effect sizes in combat veteran samples. However, considering high rates of PTSD in the present veteran population, ongoing research work is important toward improving treatment efficiency by decreasing time to symptom amelioration and increasing the amount of symptom amelioration. The proposed research aims to enhance exposure therapy outcomes for veterans with PTSD via combination treatment with PE and yohimbine hydrochloride (HCL), an alpha-2 adrenergic receptor antagonist. The proposed investigation entails a randomized, placebo-controlled trial investigating the effect of a single administration of yohimbine HCL (paired with the first session of imaginal exposure) on outcome of PE in 40 veterans with PTSD. An additional goal is to establish a pragmatic method of tracking psychophysiological measures over the course of therapy for incorporation into future clinical psychotherapy trials. Thus, in addition to traditional self- and clinician-reported psychological outcomes, heart rate and skin conductance reactivity will be measured during a standard trauma-specific imagery task before, during, and after PE treatment. We will further investigate whether changes in psychophysiological measures predict changes in patient- and clinician-reported outcome measures.

Mild traumatic brain injury and treatment response in prolonged exposure for PTSD

A proportion of U.S. veterans returning from Iraq and Afghanistan have experienced mild traumatic brain injury (mTBI), which is associated with increased risk for developing posttraumatic stress disorder (PTSD). Prolonged Exposure (PE) has proven effectiveness in the treatment of PTSD; however, some clinicians have reservations about using PE with individuals with a history of mTBI. We examined the impact of PE for veterans with PTSD and with or without a history of mTBI in a naturalistic sample of 51 veterans who received PE at a Veterans Health Administration PTSD clinic. We also analyzed previously collected data from a controlled trial of 22 veterans randomly assigned to PE or present centered therapy. For both sets of data, we found that PE reduced symptom levels and we also did not detect an effect for mTBI, suggesting that PE may be helpful for individuals with PTSD and a history of mTBI.

Managing behavioral health needs of veterans with traumatic brain injury (TBI) in primary care

Traumatic brain injury (TBI) is a frequent occurrence in the United States, and has been given particular attention in the veteran population. Recent accounts have estimated TBI incidence rates as high as 20 % among US veterans who served in Afghanistan or Iraq, and many of these veterans experience a host of co-morbid concerns, including psychiatric complaints (such as depression and post-traumatic stress disorder), sleep disturbance, and substance abuse which may warrant referral to behavioral health specialists working in primary care settings. This paper reviews many common behavioral health concerns co-morbid with TBI, and suggests areas in which behavioral health specialists may assess, intervene, and help to facilitate holistic patient care beyond the acute phase of injury. The primary focus is on sequelae common to mild and moderate TBI which may more readily present in primary care clinics.

Reduction in posttraumatic stress symptoms in Congolese refugees practicing transcendental meditation

This matched single-blind pilot study tested the effect of Transcendental Meditation® (TM) practice on symptoms of posttraumatic stress (PTS) in Congolese refugees. Urban refugees (N = 102) staying around Kampala, Uganda attended introductory meetings. After initial random assignment to the TM group, 30 refugees who revealed that they were unable to attend all meetings and were eliminated from the study. The remaining 21 TM group participants were then instructed in TM and matched with refugees in the control group on age, sex, and baseline scores on the Post-traumatic Stress Disorder Checklist-Civilian (PCL-C). All participants completed the PCL-C measure of PTS symptoms at baseline, and 30-day and 135-day posttests. The PCL-C scores in the control group trended upward. In contrast, the PCL-C scores in the TM group went from 65 on average at baseline indicating severe PTS symptoms to below 30 on average after 30 days of TM practice, and remained low at 135 days. Effect size was high (d > 1.0). Compliance with TM practice was good; most reported regular practice throughout the study. There were no adverse events. All refugees who learned TM completed the study and were able to practice TM successfully, with subsequent substantial reduction in PTS symptoms.
