Tackling hyperarousal: an integrative multimodal approach

Body-and movement-oriented interventions for posttraumatic stress disorder: An updated systematic review and meta-analysis

This study is an update of the meta-analysis we published in 2019 on the effectiveness of body- and movement-oriented interventions (BMOIs) for adults with posttraumatic stress disorder (PTSD) in decreasing PTSD symptoms and secondary outcomes of depressive symptoms, sleep disturbance, and interoceptive awareness. Search terms for BMOIs and PTSD were combined to identify eligible studies in four bibliographical databases. Articles were selected if they included adult participants with a primary diagnosis of PTSD, included BMOI as one of the investigated therapies, were designed as a comparative outcome trial with any control condition, and involved a standardized outcome measure for PTSD symptom severity. This resulted in the addition of 14 new studies compared to the 2019 study. The meta-analysis, which included 29 studies in total, resulted in a mean Hedges' g effect size of 0.50, 95% CI [0.22, 0.79], in decreasing PTSD symptoms, with very high heterogeneity, I2 = 89%. Meta-analyses of secondary outcomes resulted in Hedges' g effect sizes of 0.37, 95% CI [0.08, 0.66] for depressive symptoms; 0.62, 95% CI [0.42, 0.81] for sleep quality; and -0.10, 95% CI [-0.23, 0.43] for interoceptive awareness. The risk of bias analysis resulted in some concerns or high risk of bias in almost all included studies; only one study had a low risk of bias. We conclude that BMOIs may be valuable for patients with PTSD. There is, however, still a lack of high-quality studies with proper control conditions and long-term follow-up periods from which to draw conclusions.

Depression as a Failed Anxiety: The Continuum of Precision-Weighting Dysregulation in Affective Disorders

Depressive, anxiety, and trauma-related disorders have many symptoms in common such as unstable mood, high anxiety, sleep disturbance, impaired concentration among others. This degeneracy creates ambiguity in classifying psychiatric disorders and raises the question of their categorical vs. dimensional nature. Consequently, such ambiguity presents a dilemma for choosing diagnosis-specific vs. trans-diagnostic therapies. In this paper, I build on a theory that considers affective disorders on the continuum of stress response from normative to traumatic. Using an integrative evolutionary-stress response-predictive processing (iESP) model, I arrange affective disorders on a continuum of precision-weighting dysregulation, where depressive, anxiety and trauma-induced disorders have a characteristic pattern of precision-weighting dysregulation. I specifically address the relationship between anxiety and depressive stress responses, exploring the role of anxiety in the dynamics of depressive stress response and the resulting high co-occurrence of anxiety and depression symptoms. Finally, I discuss the model's relevance for therapy of depression.
