Introduction: There is a resurgence of interest in the therapeutic potential of psychedelic substances such as 3,4-methylenedioxymethamphetamine (MDMA). Primary findings from our randomized, double-blind, placebo-controlled, multi-site Phase 3 clinical trial of participants with severe PTSD (NCT03537014) showed that MDMA-assisted therapy induced significant attenuation in the Clinician-Administered PTSD Scale for DSM-5 compared to Therapy with placebo. Deficits in emotional coping skills and altered self-capacities constitute major obstacles to successful completion of available treatments.

This multi-site, randomized, double-blind, confirmatory phase 3 study evaluated the efficacy and safety of 3,4-methylenedioxymethamphetamine-assisted therapy (MDMA-AT) versus placebo with identical therapy in participants with moderate to severe post-traumatic stress disorder (PTSD). Changes in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) total severity score (primary endpoint) and Sheehan Disability Scale (SDS) functional impairment score (key secondary endpoint) were assessed by blinded independent assessors. Participants were randomized to MDMA-AT (n = 53) or placebo with therapy (n = 51).

Post-traumatic stress disorder (PTSD) presents a major public health problem for which currently available treatments are modestly effective. We report the findings of a randomized, double-blind, placebo-controlled, multi-site phase 3 clinical trial (NCT03537014) to test the efficacy and safety of 3,4-methylenedioxymethamphetamine (MDMA)-assisted therapy for the treatment of patients with severe PTSD, including those with common comorbidities such as dissociation, depression, a history of alcohol and substance use disorders, and childhood trauma. After psychiatric medication washout, participants ( = 90) were randomized 1:1 to receive manualized therapy with MDMA or with placebo, combined with three preparatory and nine integrative therapy sessions.

Objective: Developmental trauma disorder (DTD) is a childhood psychiatric syndrome designed to include sequelae of trauma exposure not fully captured by PTSD. This study aimed to determine whether the assessment of DTD with an independent sample of children in mental health treatment will replicate results from an initial validation study.

Methods: The DTD semi-structured interview (DTD-SI) was administered to a convenience sample in six sites in the United States (N = 271 children in mental health care, 8-18 years old, 47% female, 41% Black or Latinx) with measures of trauma history, DSM-IV PTSD, probable DSM-IV psychiatric diagnoses, emotion regulation/dysregulation, internalizing/externalizing problems, and quality of life.

Objective: Developmental trauma or chronic early childhood exposure to abuse and neglect by caregivers has been shown to have a long-lasting pervasive impact on mental and neural development, including problems with attention, impulse control, self-regulation, and executive functioning. Its long-term effects are arguably the costliest public health challenge in the United States. Children with developmental trauma rarely have a satisfactory response to currently available evidence-based psychotherapeutic and pharmacological treatments.

Objective: The emergence of updated (5th ed. American Psychiatric Association, 2013) criteria for posttraumatic stress disorder (PTSD), which includes modified criteria for young children, raises questions regarding the need for developmentally appropriate standalone psychiatric diagnosis encompassing complex trauma presentations in children. The present study addresses these questions by examining how PTSD and proposed developmental trauma disorder (DTD) diagnoses relate to functional impairment and trauma exposure using clinician-report surveys.

: Oculomotor movements have been shown to aid in the retrieval of episodic memories, serving as sensory cues that engage frontoparietal brain regions to reconstruct visuospatial details of a memory. Frontoparietal brain regions not only are involved in oculomotion, but also mediate, in part, the retrieval of autobiographical episodic memories and assist in emotion regulation. : We sought to investigate how oculomotion influences retrieval of traumatic memories by examining patterns of frontoparietal brain activation during autobiographical memory retrieval in post-traumatic stress disorder (PTSD) and in healthy controls.

Developmental trauma disorder (DTD) has been proposed as clinical framework for the sequelae of complex trauma exposure in children. In this study, we investigated whether DTD is associated with different traumatic antecedents than posttraumatic stress disorder (PTSD). In a multisite sample of 236 children referred from pediatric or mental health treatment, DTD was assessed using the DTD Structured Interview.

Objective: Developmental trauma disorder (DTD) is an integrative syndrome for assessing the biopsychosocial sequelae of early life traumatization and attachment disruption. The psychometrics of a DTD Semi-Structured Interview (DTD-SI) and the validity and structure of the DTD construct were tested.

Methods: The DTD-SI was administered by research clinicians at 5 sites between September 2011 and August 2013 to a convenience sample of 236 children ages 7-17 years (50% female, 47% black or Latino/Hispanic, 91% with trauma histories) and/or a parent, recruited in pediatric or mental health services.

Introduction: Brain/Computer Interaction (BCI) devices are designed to alter neural signals and, thereby, mental activity. This study was a randomized, waitlist (TAU) controlled trial of a BCI, EEG neurofeedback training (NF), in patients with chronic PTSD to explore the capacity of NF to reduce PTSD symptoms and increase affect regulation capacities.

Study Design: 52 individuals with chronic PTSD were randomized to either NF (n = 28) or waitlist (WL) (n = 24).

Despite the numerous studies over the past 30 years that have clarified the devastating effects of child maltreatment on mental and physical health, the role of trauma within the caregiving system remains unrecognized both in our diagnostic systems and in our dominant treatment paradigms. Research of people with histories of caregiver abuse and neglect consistently demonstrates problems with concentration, anger, panic, depression, food intake, drugs, and sleep, as well as decreased Heart RateVariability, higher levels of stress hormones, and reduced or impaired immune response. Their relationship between documented brain changes and psychopathology is complex.

Introduction: Yoga-the integrative practice of physical postures and movement, breath exercises, and mindfulness-may serve as a useful adjunctive component of trauma-focused treatment to build skills in tolerating and modulating physiologic and affective states that have become dysregulated by trauma exposure. A previous randomized controlled study was carried out among 60 women with chronic, treatment-resistant post-traumatic stress disorder (PTSD) and associated mental health problems stemming from prolonged or multiple trauma exposures. After 10 sessions of yoga, participants exhibited statistically significant decreases in PTSD symptom severity and greater likelihood of loss of PTSD diagnosis, significant decreases in engagement in negative tension reduction activities (e.

EEG Biofeedback (also known as neurofeedback) has been in use as a clinical intervention for well over 30 years; however, it has made very little impact on clinical care. One reason for this has been the difficulty in designing research to measure clinical change in the real world. While substantial evidence exists for its efficacy in treating attention deficit/hyperactivity disorder, relatively little evidence exists for its utility in other disorders including posttraumatic stress disorder (PTSD).

Background: More than a third of the approximately 10 million women with histories of interpersonal violence in the United States develop posttraumatic stress disorder (PTSD). Currently available treatments for this population have a high rate of incomplete response, in part because problems in affect and impulse regulation are major obstacles to resolving PTSD. This study explored the efficacy of yoga to increase affect tolerance and to decrease PTSD symptomatology.

Objective: Maltreatment, family violence, and disruption in primary caregiver attachment in childhood may constitute a developmental form of trauma that places children at risk for multiple psychiatric and medical diagnoses that often are refractory to well-established evidence-based mental health treatments. No integrative diagnosis exists to guide assessment and treatment for these children and adolescents. This study therefore assessed clinicians' ratings of the clinical utility of a proposed developmental trauma disorder diagnostic framework.

Childhood exposure to victimization is prevalent and has been shown to contribute to significant immediate and long-term psychological distress and functional impairment. Children exposed to interpersonal victimization often meet criteria for psychiatric disorders other than posttraumatic stress disorder (PTSD). Therefore, this article summarizes research that suggests directions for broadening current diagnostic conceptualizations for victimized children, focusing on findings regarding victimization, the prevalence of a variety of psychiatric symptoms related to affect and behavior dysregulation, disturbances of consciousness and cognition, alterations in attribution and schema, and interpersonal impairment.
