Evidence suggests that individuals undergoing successful treatment for post-traumatic stress disorder (PTSD) continue to experience PTSD symptoms. To determine the extent to which people continue to suffer from PTSD symptoms after intensive trauma-focused treatment and at six-month follow-up, despite no longer meeting diagnostic criteria for PTSD. In total, 1015 individuals with PTSD participated in an eight-day intensive trauma-focused treatment programme combining psychoeducation, physical activity, prolonged exposure, and EMDR therapy.

Eye movement desensitisation and reprocessing (EMDR) therapy primarily aims to reduce the emotional intensity or subjective disturbance associated with traumatic memories. However, to date, only one study has investigated whether a reduction in emotional intensity is related to a reduction in post-traumatic stress disorder (PTSD) symptoms. Therefore, the purpose of the present study was to determine the relationship between changes in emotional intensity of traumatic memories during EMDR therapy and treatment outcomes.

Introduction: Individuals with a personality disorder (PD) often report high exposure to adverse events. Given the strong link between negative life events and PD pathology, it is essential to evaluate trauma-focused treatments in this population. This study evaluated the effectiveness of eye movement desensitization and reprocessing (EMDR) therapy versus waitlist in reducing post-traumatic stress disorder (PTSD) symptoms and diagnostic status, distinguishing between patients with and without PTSD.

Evidence suggests that veterans with post-traumatic stress disorder (PTSD) are less likely to benefit from trauma-focused treatment than are patients with PTSD who have not been exposed to war-related trauma. However, new developments in PTSD treatment that combine several evidence-based trauma-focused therapies within a short time frame may help veterans achieve outcomes similar to those of non-veterans. In this retrospective cohort study, we examined changes in PTSD symptoms and diagnostic status after treatment between veterans and non-veterans.

Individuals with mild intellectual disability (MID; IQ 50-70) or borderline intellectual functioning (BIF; IQ 70-85) are at an elevated risk of post-traumatic stress disorder (PTSD), with PTSD symptoms possibly associated with behavioural problems. It is important to test the effectiveness of trauma-focused treatments, such as eye movement desensitisation and reprocessing (EMDR) therapy, for adults with MID-BIF, PTSD, and severe behavioural problems. To determine the safety and effectiveness of brief intensive EMDR therapy carried out by a team of rotating therapists in adults with MID-BIF, PTSD, and severe behavioural problems.

Eye movement desensitization and reprocessing (EMDR) therapy may be a promising approach when targeting addiction-related memory representations that trigger craving. We propose a link with cue-reactivity mechanisms targeted by both cognitive bias modification training and cue-exposure therapy, including increased cue-devaluation, reduction in cognitive biases, and violation of dysfunctional expectancies. In this commentary, we propose a framework explaining the effects of addiction-focused EMDR therapy based on insights from working memory and inferential processing accounts, empirical evidence of underlying EMDR mechanisms, and the broader cue-exposure literature.

Psychotherapeutic interventions aimed at treating posttraumatic stress disorder (PTSD) in adolescents and young adults are hampered by high dropout rates. Looking at the results from adult treatments, short, intensive, outpatient treatment programmes may offer a promising alternative, but it has yet to be tested in this young population. To assess the results of a six-day intensive outpatient trauma-focused treatment programme for young individuals (12-25 years) with PTSD.

Article Synopsis
  • Trauma and post-traumatic stress play a significant role in voice-hearing, and trauma-focused therapy (TFT) may help, but previous research has been inconclusive.
  • The study aimed to evaluate the impact of TFT on voice-hearing in individuals with PTSD and psychosis, using daily questionnaires to assess changes over time.
  • Results indicated that TFT led to a significant reduction in voice-hearing compared to a waiting-list control group, with improvements in PTSD symptoms also correlated with reductions in voice-hearing.

  • Chronic painful temporomandibular disorders (TMD) and bruxism are often linked with post-traumatic stress disorder (PTSD), but how to treat them together is unclear.* -
  • A study found that evidence-based trauma-focused treatment led to significant decreases in chronic painful TMD, pain intensity, awake bruxism, and sleep bruxism over time, with improvements maintained at a 6-month follow-up.* -
  • The findings suggest that addressing PTSD through trauma-sensitive treatments could benefit individuals suffering from both PTSD and chronic painful TMD, indicating a need for integrated therapeutic approaches.*

Article Synopsis
  • Policymakers and health providers are focusing more on cost-effectiveness analyses (CEA) for mental health treatments, especially due to rising costs in this sector.
  • The study compared the cost-effectiveness of a phased treatment approach (STAIR-EMDR) versus direct trauma-focused treatment (EMDR only) in patients with PTSD linked to childhood abuse.
  • Results showed no significant differences in effectiveness, but STAIR-EMDR had higher societal costs, making it less cost-effective than EMDR-only therapy for PTSD treatment.

Despite the availability of various treatment approaches for patients with posttraumatic stress disorder (PTSD), some patients do not respond to these therapies, and novel treatment approaches are needed. This study investigated the efficacy of mifepristone, a glucocorticoid receptor antagonist, in treatment-resistant PTSD patients. Three patients with PTSD who were resistant to standard psychological and pharmacological treatments were prescribed mifepristone (600-1,200 mg/day) for 1 week.

Introduction: Visual Schema Displacement Therapy (VSDT) is a novel approach showing promise in mitigating distressing memories, akin to Eye Movement Desensitization and Reprocessing (EMDR).

Objectives: This study aimed to determine the safety, feasibility, and effectiveness of VSDT in individuals with post-traumatic stress disorder (PTSD), comparing it to EMDR therapy and a waitlist control condition (WLCC). It was hypothesized that the application of VSDT would be safe and PTSD symptoms significantly be reduced from both baseline to post-treatment and from baseline to follow-up in the VSDT and EMDR therapy conditions.

Research has shown that the impact of traumatic events and circumstances on individuals is cumulative and potentially has a wide range of harmful consequences, including negative consequences on mental health. One such consequence is the development of a personality disorder, a persistent mental condition characterized by a pronounced pattern of difficulties in impulse control, emotional regulation, cognitive functions, self-esteem, and interpersonal relationships. A wide array of studies indicates that the personal history of individuals with a personality disorder is often marked by exposure to traumatic events or other types of adverse childhood experiences (ACEs).

Article Synopsis
  • Knowledge of predictors and moderators is crucial for enhancing PTSD treatment effectiveness in those affected by childhood abuse, with the study investigating variables that could impact treatment outcomes.
  • The research compared a two-step treatment method (STAIR plus EMDR) versus a direct EMDR approach for PTSD, focusing on various psychological symptoms as predictors and moderators.
  • Findings indicated that pre-treatment PTSD severity and dissociative symptoms were major predictors of poor treatment outcomes, suggesting that more extensive or mixed treatment options might be necessary for those with severe PTSD symptoms.

Background: Several widely studied therapies have proven to be effective in the treatment of post-traumatic stress disorder (PTSD). However, there is still room for improvement because not all patients benefit from trauma-focused treatments. Improvements in the treatment of PTSD can be achieved by investigating ways to enhance existing therapies, such as eye movement desensitization and reprocessing (EMDR) therapy, as well as exploring novel treatments.
