Enhancement of psychosocial treatment with D-cycloserine: models, moderators, and future directions

Advances in the understanding of the neurobiology of fear extinction have resulted in the development of d-cycloserine (DCS), a partial glutamatergic N-methyl-D-aspartate agonist, as an augmentation strategy for exposure treatment. We review a decade of research that has focused on the efficacy of DCS for augmenting the mechanisms (e.g., fear extinction) and outcome of exposure treatment across the anxiety disorders. Following a series of small-scale studies offering strong support for this clinical application, more recent larger-scale studies have yielded mixed results, with some showing weak or no effects. We discuss possible explanations for the mixed findings, pointing to both patient and session (i.e., learning experiences) characteristics as possible moderators of efficacy, and offer directions for future research in this area. We also review recent studies that have aimed to extend the work on DCS augmentation of exposure therapy for the anxiety disorders to DCS enhancement of learning-based interventions for addiction, anorexia nervosa, schizophrenia, and depression. Here, we attend to both DCS effects on facilitating therapeutic outcomes and additional therapeutic mechanisms beyond fear extinction (e.g., appetitive extinction, hippocampal-dependent learning).F31 MH103969 - NIMH NIH HHS; K24 DA030443 - NIDA NIH HHS; R34 MH099309 - NIMH NIH HHS; R34 MH086668 - NIMH NIH HHS; R21 MH102646 - NIMH NIH HHS; R34 MH099318 - NIMH NIH HH

The role of dissociation-related beliefs about memory in trauma-focused treatment

OBJECTIVE: Dysfunctional cognitions play a central role in the development of post-traumatic stress disorder (PTSD). However the role of specific dissociation-related beliefs about memory has not been previously investigated. This study aimed to investigate the role of dissociation-related beliefs about memory in trauma-focused treatment. It was hypothesized that patients with the dissociative subtype of PTSD would show higher levels of dissociation-related beliefs, dissociation-related beliefs about memory would decrease after trauma-focused treatment, and higher pre-treatment dissociation-related beliefs would be associated with fewer changes in PTSD symptoms.METHOD: Post-traumatic symptoms, dissociative symptoms, and dissociation-related beliefs about memory were assessed in a sample of patients diagnosed with PTSD ( n = 111) or the dissociative subtype of PTSD ( n  = 61). They underwent intensive trauma-focused treatment consisting of four or eight consecutive treatment days. On each treatment day, patients received 90 min of individual prolonged exposure (PE) in the morning and 90 min of individual eye movement desensitization and reprocessing (EMDR) therapy in the afternoon. The relationship between dissociation-related beliefs about memory and the effects of trauma-focused treatment was investigated. RESULTS: Dissociation-related beliefs about memory were significantly associated with PTSD and its dissociative symptoms. In addition, consistent with our hypothesis, patients with the dissociative subtype of PTSD scored significantly higher on dissociation-related beliefs about memory pre-treatment than those without the dissociative subtype. Additionally, the severity of these beliefs decreased significantly after trauma-related treatment. Contrary to our hypothesis, elevated dissociation-related beliefs did not negatively influence treatment outcome.CONCLUSION: The results of the current study suggest that dissociation-related beliefs do not influence the outcome of trauma-focused treatment, and that trauma-focused treatment does not need to be altered specifically for patients experiencing more dissociation-related beliefs about memory because these beliefs decrease in association with treatment.</p

Adding physical activity to intensive trauma-focused treatment for post-traumatic stress disorder: results of a randomized controlled trial

IntroductionThis randomized controlled trial examined the effectiveness of physical activity added to an intensive trauma-focused treatment (TFT) for post-traumatic stress disorder (PTSD) in comparison to adding non-physical control activities.MethodsA total of 119 patients with PTSD were randomly assigned to a physical activity condition (PA; n = 59) or a non-physical activity control condition (nPA; n = 60). The 8-day intensive TFT programme consisted of daily prolonged exposure, EMDR therapy, and psychoeducation, which was complemented with physical activities versus controlled mixtures of guided (creative) tasks. As a primary outcome, the change in clinician and self-reported PTSD symptoms from pre-to post-treatment and at 6 months follow-up were measured.ResultsIntent-to-treat linear mixed-effects models showed no significant differences between the PA and nPA conditions on change in PTSD severity. Clinician and self-reported PTSD symptoms significantly decreased for both conditions, with large effect sizes (e.g., CAPS-5 dpre-post = 2.28). At post-treatment, 80.0% in the PA, and 82.7% in the nPA condition no longer met the diagnostic criteria for PTSD. Regarding the loss of Complex PTSD diagnoses this was 92.5% and 95.0%, respectively.ConclusionEither with additional physical or non-physical activities, intensive TFT is very effective for the treatment of (Complex) PTSD, as reflected by large effect sizes and loss of diagnostic status in both groups.Clinical trial registrationTrialregister.nl Identifier: Trial NL9120

Sequence matters: Combining Prolonged Exposure and EMDR therapy for PTSD

Objective Investigating the influence of the sequence in which two evidence-based trauma-focused treatments are offered to PTSD-patients. Methods PTSD-patients were treated using an intensive eight-day treatment program, combining Prolonged Exposure (PE) and EMDR therapy. Forty-four patients received a PE session in the morning and an EMDR session in the afternoon, while 62 patients received the reversed sequence (EMDR followed by PE). Outcome measures were PTSD symptom severity and subjective experiences. Results Patients who received PE first and EMDR second showed a significantly greater reduction in PTSD symptoms, patients preferred this sequence and valued the treatment sessions as significantly more helpful compared to patients in the EMDR-first condition. Conclusion Albeit explorative, PE and EMDR therapy can be successfully combined, but sequence matters. First applying PE sessions before EMDR sessions resulted in better treatment outcome, and better subjective patient's evaluations in terms of treatment helpfulness and preference

Trauma-related symptoms:A critical evaluation of popular treatments

Voor de behandeling van traumagerelateerde klachten zijn effectieve, evidence-based behandelingen beschikbaar, maar relatief weinig mensen krijgen daadwerkelijk zo'n behandeling. In plaats daarvan worden andere behandelingen gegeven die populair zijn, waaronder lichaamsgerichte behandelingen, dierondersteunde therapie, speltherapie, EMDR toegepast op vermijding, de Lovett-methode voor preverbaal trauma, geleide synthese en deprogrammeren. Wij nemen deze behandelingen onder de loep. Zijn ze effectief? Wat is het veronderstelde werkingsmechanisme ervan? En wat zijn de mogelijke risico's van deze behandelingen? In de discussie bespreken we mogelijke redenen waarom deze en vergelijkbare behandelingen in de klinische praktijk worden verkozen boven evidence-based behandelingen en een aantal redeneerfouten die aan deze keuzes bijdragen.In clinical practice, various forms of evidence-based treatment for the treatment of trauma-related symptoms are available. However, relatively few patients receive one of these forms of treatment. Instead, patients receive other popular treatments for trauma-related complaints, such as body-focused treatments, animal-assisted therapy, EMDR for avoidance, play therapy, the Lovett method for preverbal trauma, guided synthesis, and deprogramming. We summarize the effectiveness, hypothesized working mechanism, and possible risks of these treatment methods. In the discussion, we explain possible reasons why these and comparable methods are preferred in clinical practice above evidence-based treatments and several reasoning errors which can contribute to these choices
