12-month follow-up of intensive outpatient treatment for PTSD combining prolonged exposure therapy, EMDR and physical activity

BackgroundPreliminary evidence shows promising treatment outcomes at short-term follow-up for intensive posttraumatic stress disorder (PTSD) treatment, but long-term follow-up studies are sparse. This study is a sequel to a previous pilot study and open trial, set out to investigate treatment outcomes at 12-month follow-up for outpatients completing an 8-day intensive treatment for PTSD.MethodsAll patients were diagnosed with PTSD and had multiple previous psychotherapy attempts (M = 3.1). Patients were assessed at pre-treatment, post-treatment, 3- and 12-month follow-up. Of 35 treated patients, 32 (91.4%) attended the long-term follow-up assessment. The treatment programme combined prolonged exposure therapy, eye movement desensitization and reprocessing, and physical activity.ResultsThe effect sizes indicated large reductions in symptoms of PTSD, depression, anxiety, interpersonal problems, and well-being. Changes in functioning showed a small-medium effect. Results were stable across the follow-up period. The treatment response rates showed that 46–60% of patients achieved recovery with respect to PTSD symptoms, and that 44–48% no longer met diagnostic criteria for PTSD.ConclusionsTime-limited and concentrated outpatient treatment for PTSD can yield large and enduring positive outcomes. Controlled trials are needed to establish relative efficacy.Trial registrationThe study was registered in Current Research Information System In Norway (Cristin). Cristin-project-ID: 654,790.

Influence of Stress Severity on Contextual Fear Extinction and Avoidance in a Posttraumatic-like Mouse Model.

Posttraumatic stress disorder (PTSD) is a widespread fear-related psychiatric affection associated with fear extinction impairments and important avoidance behaviors. Trauma-related exposure therapy is the current first-hand treatment for PTSD, yet it needs to be improved to shorten the time necessary to reach remission and increase responsiveness. Additional studies to decipher the neurobiological bases of extinction and effects on PTSD-like symptoms could therefore be of use. However, a PTSD-like animal model exhibiting pronounced PTSD-related phenotypes even after an extinction training directly linked to the fearful event is necessary. Thus, using a contextual fear conditioning model of PTSD, we increased the severity of stress during conditioning to search for effects on extinction acquisition and on pre- and post-extinction behaviors. During conditioning, mice received either two or four electrical shocks while a control group was constituted of mice only exposed to the context. Stressed mice exhibited important fear generalization, high fear reaction to the context and selective avoidance of a contextual reminder even after the extinction protocol. Increasing the number of footshocks did not induce major changes on these behaviors.

A randomized controlled trial testing theory-driven enhancements to increase the efficacy of and engagement in a brief cognitive-behavioural therapy text-message intervention for co-occurring posttraumatic stress disorder symptoms and alcohol misuse.

Engaging individuals with co-occurring posttraumatic stress disorder (PTSD) and alcohol misuse (AM) in effective treatments is difficult. Brief, self-directed approaches that deliver empirically supported intervention techniques, such as cognitive-behavioural therapy (CBT) strategies, via technology may be effective and easier-to-access alternatives to traditional in-person therapy approaches for PTSD + AM. This paper describes the protocol for an intervention development study (NCT05372042) that evaluates a text-message intervention combining CBT texts with techniques from cognitive psychology (message framing) and social psychology (growth mindsets) for treatment of PTSD + AM. The study uses a 3 (message framing: gain vs. loss vs. no framing) × 2 (mindset: growth mindsets vs. not) factorial design to test enhancements to CBT texts. Individuals age 18+, who report symptoms of PTSD and AM, will be recruited to participate. Participants will complete screening, verification, and baseline measures. They will be randomized to condition and receive 3 text messages per week for 4 weeks. Participants will be assessed at post-, 1-, and 3-month follow-up. Analyses will evaluate whether framing and growth mindsets enhance the efficacy of CBT texts. A priori decision rules will be applied to select the intervention condition that is both the most effective and the simplest, which will be tested in a follow-up randomized controlled trial. This study will identify the simplest, most efficacious CBT intervention for PTSD + AM. Its use of cognitive and social psychology-based enhancement and of a factorial decision can serve as examples of how to enhance and increase engagement in brief, self-directed CBT interventions.

Brief family involvement enhances veteran homework quality during trauma-focused psychotherapy.

Homework has been shown to improve outcomes in cognitive-behavioral therapy, though less is known about the importance of homework during trauma-focused psychotherapy. Similarly, prior research suggests family context plays a key role in posttraumatic stress disorder (PTSD)-related distress and treatment engagement. One potential way that families can facilitate better treatment outcomes is by promoting homework engagement. This study examined the impact of a brief family intervention (BFI) for PTSD toward this aim. We hypothesized that veterans with PTSD whose family members (FMs) received the BFI would have better homework completion and quality than those who did not receive the BFI. This mixed-methods analysis examined 24 veteran-family dyads enrolled in a randomized clinical trial examining the BFI. All veterans were currently engaged in trauma-focused psychotherapy. Each veteran's clinician rated their homework quality and completion after each therapy session. A subset of dyads also completed semistructured interviews posttreatment. A rapid qualitative analysis approach was used to examine themes in shifting family behavior post-BFI. Quantitative analyses yielded partial support for our hypotheses: those in the BFI condition had significantly higher clinician-rated homework quality. While participants in the BFI condition had a higher homework completion rate, this difference did not reach statistical significance. Qualitative analyses suggested that the BFI prompted meaningful discussions about PTSD and increased FMs' use of supportive (rather than accommodative) behavior when responding to PTSD-related distress. Involving FMs in PTSD treatment appears to shift the family context in a manner that improves homework quality in veterans. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Post-traumatic stress disorder in a national sample of preadolescent children 9 to 10 years old: Prevalence, correlates, clinical sequelae, and treatment utilization

Although posttraumatic stress disorder (PTSD) has been well characterized in adults, its epidemiology in children is unclear. The current study provides the first population-based examination of the prevalence of PTSD, sociodemographic and psychiatric correlates, clinical sequelae, and associations with psychiatric treatment in preadolescents 9-10 years old in the United States. Data from the Adolescent Brain and Cognitive Development (ABCD) Study (release 5.0) was analyzed. Participants (unweighted n = 11,875) were recruited from 21 sites across the United States. Current and lifetime PTSD prevalence were estimated, as was treatment use among children with PTSD. Sociodemographic, psychiatric correlates and sequelae of PTSD were analyzed using logistic regression, as was the association between PTSD and psychiatric treatment. After the application of propensity weights, lifetime prevalence of PTSD was 2.17%. Sexual minority status, being multiracial, having unmarried parents, and family economic insecurity were associated with greater odds of PTSD. Among psychiatric disorders, separation anxiety was most strongly associated with PTSD, although general comorbid psychopathology was associated with greater odds of PTSD. Prior history of PTSD predicted a new onset of other psychiatric disorders after PTSD remission. Nearly one in three children with lifetime PTSD did not receive psychiatric treatment, despite negative long-term outcomes of PTSD and significant psychiatric comorbidity. Even among preadolescents who experience full remission of PTSD, a significant risk for future psychiatric illness remains. Further, the current findings underscore the need for improved efforts to reduce unmet treatment needs among those with PTSD at this age.

Can Baseline Patient Clinical and Demographic Characteristics Predict Response to Early Posttraumatic Stress Disorder Interventions After Physical Injury?

Objective A growing evidence base supports stepped care interventions for the early treatment of posttraumatic stress disorder (PTSD) after physical injury. Few investigations have examined the characteristics of patients who do and do not respond to these interventions. Method This investigation was a secondary analysis that used previously collected data from three randomized clinical trials of stepped care interventions (patient N = 498). The study hypothesized that a subgroup of patients would manifest persistent PTSD symptoms regardless of randomization to intervention or control conditions, and that characteristics present at the time of baseline injury hospitalization could distinguish patients who would develop persistent symptoms from potential treatment responders. Regression analyses identified baseline patient clinical and demographic characteristics that were associated with persistent PTSD symptoms over the 6-months post-injury. Additional analyses identified treatment attributes of intervention patients who were and were not likely to demonstrate persistent symptoms. Results A substantial subgroup of patients (n = 222, 44.6%) demonstrated persistent PTSD symptoms over time. Greater numbers of pre-injury trauma, pre-injury PTSD symptoms, elevated early post-injury PTSD symptoms, unemployment, and non-White race identified patients with persistent symptoms. Patients with ≥3 of these baseline risk characteristics demonstrated diminished treatment responses when compared to patients with <3 characteristics. Intervention patients with ≥3 risk characteristics were less likely to engage in treatment and required greater amounts of interventionist time. Conclusions Injured trauma survivors have readily identifiable characteristics at the time of hospitalization that can distinguish responders to PTSD stepped care interventions versus patients who may be treatment refractory.

CK2 negatively regulates the extinction of remote fear memory

Cognitive behavioral therapy, rooted in exposure therapy, is currently the primary approach employed in the treatment of anxiety-related conditions, including post-traumatic stress disorder (PTSD). In laboratory settings, fear extinction in animals is a commonly employed technique to investigate exposure therapy; however, the precise mechanisms underlying fear extinction remain elusive. Casein kinase 2 (CK2), which regulates neuroplasticity via phosphorylation of its substrates, has a significant influence in various neurological disorders, such as Alzheimer’s disease and Parkinson’s disease, as well as in the process of learning and memory. In this study, we adopted a classical Pavlovian fear conditioning model to investigate the involvement of CK2 in remote fear memory extinction and its underlying mechanisms. The results indicated that the activity of CK2 in the medial prefrontal cortex (mPFC) of mice was significantly upregulated after extinction training of remote cued fear memory. Notably, administration of the CK2 inhibitor CX-4945 prior to extinction training facilitated the extinction of remote fear memory. In addition, CX-4945 significantly upregulated the expression of p-ERK1/2 and p-CREB in the mPFC. Our results suggest that CK2 negatively regulates remote fear memory extinction, at least in part, by inhibiting the ERK-CREB pathway. These findings contribute to our understanding of the underlying mechanisms of remote cued fear extinction, thereby offering a theoretical foundation and identifying potential targets for the intervention and treatment of PTSD.

A Systematic Review of Social Support Instruments for Measurement-Based Care in Posttraumatic Stress Disorder.

Social support is a treatment target for individuals with post-traumatic stress disorder (PTSD) but is not systematically assessed in clinical care. This review evaluated the quality of patient-reported social support instruments used in PTSD research to identify candidates for measurement-based care (MBC) with this population. A systematic review identified all validated measures of social support used in research with traumatized populations after 1990. Instrument development/validation studies were then evaluated using components of the updated COSMIN guidelines. Instruments were rated for clinical utility and evidence of their psychometric properties in use with traumatized individuals was synthesized. Twenty-nine instruments were identified across 231 studies. Evaluation of development articles found 14 instruments with sufficient evidence of content validity and internal consistency reliability that could be considered for clinical use. Of these, nine had comparable properties in traumatized samples and could be preliminarily included in MBC of social support in the treatment of PTSD. Additional studies on measures' responsiveness and test-retest reliability are needed. Existing measures of social support could improve clinical care of PTSD when used routinely to provide feedback on this critical component of health. MBC of social support may also improve clinical care of other psychiatric conditions.

Case report: the addition of olfaction to virtual reality enhanced exposure therapy for PTSD

Posttraumatic stress disorder (PTSD) occurs in approximately 20% of individuals following exposure to a potentially traumatic event. Re-experiencing in the form of intrusive memories is a hallmark feature, and often includes sensory elements, including odor. A small body of studies have examined the relationship between PTSD and odor evoked memories. Patients avoid smells that remind them of their traumatic event, and odors are known triggers for intrusive memories and distress. PTSD is associated with higher ratings of odor intensity and unpleasantness however accuracy of odor detection is often impaired. It has been suggested that adding trauma-related odors will enhance treatment, however little data exists. This case study illustrates the addition of trauma specific olfaction in Virtual Reality (VR) enhanced exposure therapy for combat related PTSD. Treatment was successful, the patient no longer met criteria for PTSD at the end of treatment, and self-report symptoms scores indicated clinically significant reductions. The patient indicated at the end of treatment that he would not have been helped had the therapy not used VR, and the addition of odors helped him process the traumatic memories. Future research should assess the addition of olfaction in a systematic way, in order to assess its specific impact in the effectiveness of PTSD treatment.

Auditory Steady-State Evoked Potentials in Post Traumatic Stress Disorder: Introduction of a Potential Biomarker.

Objective: The lack of steady-state evoked potential (SSEP) studies on post-traumatic stress disorder (PTSD) has led to undiscovered useful information about the pathophysiology of the disorder. Thus, we explored SSEP patterns in PTSD patients during a stop-signal task to disclose possible impairments in these informative brain potentials. Method : 25 adult patients with PTSD and 25 healthy adults participated in this research. Subjects were assessed with electroencephalography while the tone signal stimuli at 40 Hz were used to evoke SSEPs and subjects performed a stop-signal task. The amplitude and phase of SSEPs were then computed in different brain regions. The subjects were also evaluated using the Mississippi PTSD questionnaire. Appropriate statistical methods such as repeated measure ANOVA were used to compare the two groups, and the correlation between SSEPs and clinical symptoms was assessed using Pearson correlation analysis. Results: Patients showed considerably poorer performance in the cognitive task (P < 0.01), accompanied by raised SSEP phase and amplitude in the anterior and midline regions compared to healthy controls (P < 0.05). The Mississippi total score was positively correlated with the SSEP amplitude in the midline region (r = 0.62, P < 0.05). Furthermore, based on ROC analysis, the SSEP amplitude in the midline region provided an excellent AUC value (AUC = 0.850) for distinguishing patients with PTSD from normal subjects. Conclusion: Current findings suggest that abnormalities in the anterior and midline cortical neural networks are involved in the pathophysiology of PTSD. Importantly, midline abnormalities may provide a clinically-relevant measure for researchers wishing to assess the use of biomarkers for early diagnosis of PTSD as well as to evaluate new therapeutic and management approaches in the treatment of PTSD.

Heart rate reactivity during trauma recall as a predictor of treatment outcome in cognitive processing therapy for PTSD

Emotional engagement when recollecting a trauma memory is considered a key element of effective trauma-focused therapy. Research has shown that reduced physiological reactivity during trauma recall is associated with worse treatment outcomes for posttraumatic stress disorder (PTSD), but this has yet to be examined in a cognitively oriented treatment. This study examined whether pretreatment heart rate (HR) reactivity during trauma recall predicts PTSD symptom improvement and treatment dropout during Cognitive Processing Therapy (CPT) for PTSD. Participants were 142 women with PTSD secondary to interpersonal violence enrolled in one of two clinicals trials. HR reactivity reflected the mean increase in HR after listening to two 30-s scripts of the trauma memory prior to treatment. Linear mixed-effects models showed the effect of HR reactivity on change in total PTSD symptoms was not significant, but lower HR reactivity predicted less improvement in reexperiencing and avoidance and was associated with increased dropout. Findings suggest pretreatment physiological reactivity to the trauma memory may be a prognostic indicator of some elements of treatment response in CPT. Results tentatively support the importance of emotional activation during trauma recall in cognitive treatment of PTSD, though more research is needed to clarify how low HR reactivity impacts treatment.

Impact of suicidality on delayed-onset post-traumatic stress disorder is modified by age: A two-year longitudinal study

ObjectivesThis study aimed to investigate the relationship between early suicidality and post-traumatic stress disorder (PTSD) onset in patients with physical injuries, focusing on age as a modifying factor. MethodsAt baseline, 1014 patients were evaluated for suicidality, age divided into younger (<60 years) vs. older (≥60 years) groups, and potential covariates. PTSD was diagnosed at follow-up at 3, 6, 12, and 24 months, and then were categorized into early-onset (within the first six months after trauma) and delayed-onset (more than six months after trauma). Logistic regression models were used after adjusting for covariates. ResultsPresence of suicidality at baseline was significantly associated with delayed-onset PTSD in older but not younger patients with significant interaction terms, whereas it was significantly associated with early-onset PTSD across all age groups. ConclusionAge-specific associations were found between suicidality and PTSD onset. The findings highlight the importance of early suicidality assessment, especially in older patients for ongoing monitoring and support, and underscore the critical need for early PTSD identification and intervention for all ages.

D-Pinitol mitigates post-traumatic stress disorder-like behaviors induced by single prolonged stress in mice through mineralocorticoid receptor antagonism

Post-traumatic stress disorder (PTSD) is a mental illness that can occur in individuals who have experienced trauma. Current treatments for PTSD, typically serotonin reuptake inhibitors, have limited effectiveness for patients and often cause serious adverse effects. Therefore, a novel class of treatment with better pharmacological profile is necessary. D-Pinitol has been reported to be effective for depression and anxiety disorders, but there are no reports associated with PTSD. In the present study, we investigated the effects of D-pinitol in a mouse model of PTSD induced by a single prolonged stress (SPS) protocol. We examined the therapeutic effects of D-pinitol on emotional and cognitive impairments in the SPS mouse model. We also investigated the effects of D-pinitol on fear memory formation. Mineralocorticoid receptor transactivation assay, Western blot, and quantitative PCR were employed to investigate how D-pinitol exerts its pharmacological activities. D-Pinitol ameliorated PTSD-like behaviors in a SPS mouse model. D-Pinitol also normalized the increased mRNA expression levels and protein levels of the mineralocorticoid receptor in the amygdala. A mineralocorticoid receptor agonist reversed the effects of D-pinitol on fear extinction and recall, and the antagonistic property of D-pinitol against the mineralocorticoid receptor was confirmed in vitro. Our findings suggest that D-pinitol could serve as a potential therapeutic agent for PTSD due to its antagonistic effect on the mineralocorticoid receptor.

How is trauma-focused therapy experienced by adults with PTSD? A systematic review of qualitative studies

BackgroundTrauma-focused therapies (TFTs) are first-line treatments for posttraumatic stress disorder (PTSD). However, TFTs are under-utilised, partly due to clinicians’ and patients' fear that TFT is too challenging or harmful. We review the qualitative studies on how adults with PTSD experience TFTs to enhance the understanding of user perspectives, therapeutic processes, and outcomes.MethodsPubMed, PsychINFO and PTSDPubs were searched between October 1st and November 30th, 2021. Study quality assessments were undertaken, and studies were analysed using a descriptive-interpretative approach. Nine studies were included.ResultsThe analysis resulted in the identification of four key domains, representing a temporal sequence of TFT stages: Overcoming ambivalence towards TFT, Experience of treatment elements, Motivation for dropout/retention, and Perceived changes post-treatment.ConclusionAlthough many participants reported high levels of distress and considered dropping out, only a minority did eventually drop out and most patients expressed that the hardships in therapy were necessary for PTSD improvement. Establishing a safe therapeutic environment and working with the ambivalence towards treatment was essential for retention. This review serves a dual purpose, to shed light on diverse TFT experiences found to be important for treatment satisfaction, and to elucidate common treatment patterns. The results can be used in preparing patients for therapy and in training TFT therapists. Studies had moderate to high quality, and more studies of experiences of TFT non-responders and dropouts in a non-veteran population are needed to further our understanding of the utility and limitations of TFTs.

Impact of PTSD treatment on postconcussive symptoms in veterans: A comparison of sertraline, prolonged exposure, and their combination

Many Veterans who served in Iraq and Afghanistan struggle with posttraumatic stress disorder (PTSD) and the effects of traumatic brain injuries (TBI). Some people with a history of TBI report a constellation of somatic, cognitive, and emotional complaints that are often referred to as postconcussive symptoms (PCS). Research suggests these symptoms may not be specific to TBI. This study examined the impact of PTSD treatment on PCS in combat Veterans seeking treatment for PTSD. As part of a larger randomized control trial, 198 Operation Iraqi Freedom, Operation Enduring Freedom, Operation New Dawn (OIF/OEF/OND) Veterans with PTSD received Prolonged Exposure Therapy, sertraline, or the combination. Potential deployment related TBI, PCS, PTSD and depression symptoms were assessed throughout treatment. Linear mixed models were used to predict PCS change over time across the full sample and treatment arms, and the association of change in PTSD and depression symptoms on PCS was also examined. Patterns of change for the full sample and the subsample of those who reported a head injury were examined. Results showed that PCS decreased with treatment. There were no significant differences across treatments. No significant differences were found in the pattern of symptom change based on TBI screening status. Shifts in PCS were predicted by change PTSD and depression. Results suggest that PCS reduced with PTSD treatment in this population and are related to shift in depression and PTSD severity, further supporting that reported PCS symptoms may be better understood as non-specific symptoms.

PTSD, depression, and treatment outcomes: A latent profile analysis among active duty personnel in a residential PTSD program

Depression frequently co-occurs with posttraumatic stress disorder (PTSD), including among active duty service members. However, symptom heterogeneity of this comorbidity is complex and its association with treatment outcomes is poorly understood, particularly among active duty service members in residential treatment. This study used latent profile analysis (LPA) to identify symptom-based subgroups of PTSD and depression among 282 male service members in a 10-week, residential PTSD treatment program with evidence-based PTSD psychotherapies and adjunctive interventions. The PTSD Checklist–Military Version and Patient Health Questionnaire-8 were completed by service members at pre- and posttreatment and weekly during treatment. Multilevel models compared subgroups on PTSD and depression symptom change across treatment. LPA indicated four subgroups provided optimal fit: Depressive (high depression severity, low PTSD avoidance; n = 33, 11.7%), Avoidant (high PTSD avoidance, moderate depression severity; n = 89, 31.6%), Moderate (moderate PTSD and depression severity; n = 27, 9.6%), and Distressed (high PTSD and depression severity; n = 133, 47.2%). Treatment response differed across classes for both PTSD and depression outcomes (time × LPA class interaction ps < 0.001). In PTSD models, post-hoc comparisons indicated the Moderate class was associated with less PTSD symptom improvement relative to the other classes (ps < 0.006). In depression models, symptom reduction was greatest for the Distressed and Depressive subgroups relative to the other two classes (ps < 0.009). Study results provide an initial model for two prevalent, impairing disorders among service members and show how these symptom-based subgroups may differentially respond to residential PTSD treatment.

The Effects of Ayahuasca on Psychological Disorders: A Systematic Literature Review.

Ayahuasca is an original Amazonian brew made from the vines and leaves of Psychotroa viridis and Banisteriopsis caapi. Both P. viridis and B. caapi give this brew its unique psychedelic properties which have been revered over centuries.In recent years, ayahuasca has gained attention as a potential therapeutic tool for mental health disorders, including substance abuse and depression. The uniqueness of ayahuasca's therapeutic potential is that it is an amalgamation of its biochemical makeup and the ritual guided by a shaman, along with the interpretation of the participant of their experience. The boom of "ayahuasca tourism" has brought forth testimonies of feeling "cured" of depression, and substance abuse and an improvement in overall well-being. This systematic literature review focuses on summarizing the recently available research on the effectiveness of ayahuasca as a treatment for depression, anxiety, substance abuse, eating disorders, and post-traumatic stress disorder. It also focuses on understanding the effects it has on personality traits that play a significant role in the manifestation of the above-listed mental health conditions effects. Additionally, the review investigates the importance and role the ritual itself plays, often described as the "mystical experience". This systematic literature review aims to explore the current state of knowledge regarding the use of ayahuasca for numerous mental health conditions by analyzing medical research papers published no earlier than September 2017 to no later than May 2023 from Google Scholar and PubMed. A total of 43 articles met the criteria and were used for detailed analysis. This review will synthesize the findings of the studies, examining the potential therapeutic effects of ayahuasca on multiple mental health disorders, the significance of the "mystical experience,"and the mechanisms of action underlying its effects. Through the review, ayahuasca proves to be a worthwhile therapeutic tool that if used in the right setting influences mind, body, and spirit. It is important to note that most studies used in this article relied on surveys and self-reporting proving to be a limitation as no clear standard has been achieved to test the efficacy of ayahuasca. The respect for the culture and origin needs to be retained as Western medicine dwells deeper into ayahuasca's benefits.

Post-traumatic stress disorder, dyssomnias, and metabolic syndrome

Post-traumatic stress disorder (PTSD) and metabolic syndrome (MetS) frequently coexist and share neurobiological and clinical features. In particular, the results of meta-analyses indicate a higher prevalence of MetS in patients with PTSD compared to the general population. PTSD is also a recognized risk factor for MetS. This synchronicity can be partially explained by pathogenetic pathways present in both conditions. These include genetic factors, dysfunction of the hypothalamic-pituitary-adrenal axis, chronic low-grade inflammation, oxidative stress, insulin resistance, and immune dysregulation. Thus, similar mechanisms are involved in the clinical worsening of PTSD and the development of adverse cardiovascular events associated with MetS. Dyssomnias are one of the characteristic clinical features of PTSD. Today, it is believed that posttraumatic circadian rhythm disorders are the core and not a secondary feature of PTSD, which mediate the neurobiological correlates of disorders due to homeostasis imbalance. At the same time, dyssomnias, chronodestruction, and depressive disorders are part of the pathogenesis of insulin resistance, obesity, and MetS. Thus, treatment of dyssomnias is one of the key tasks in the prevention and treatment of comorbid PTSD and MetS. Regulation of sleep processes and circadian rhythms through exogenous intervention, especially with melatonergic drugs, is likely to be a key part of preventing and treating dyssomnias in people who have both PTSD and MetS. The purpose of this review is to analyze the specifics of the relationships between PTSD and MetS, PTSD and dyssomnias, MetS and sleep disorders. We conducted the search in Scopus, Science Direct (from Elsevier), and PubMed, including Medline databases. The key words used were “post-traumatic stress disorder,” “dyssomnias,” “chronodestruction,” and “metabolic syndrome”. The identification of research findings that were not found during online searches involved manual searching of the bibliography of publications.

An Overview of Written Exposure Therapy: A Brief Treatment for PTSD

This article provides an overview of written exposure therapy (WET), which is a brief treatment approach for posttraumatic stress disorder (PTSD). The development of the treatment is described and the research supporting its efficacy and effectiveness is discussed. To date, research has found WET to be an effective treatment approach for PTSD, having treatment outcomes that are noninferior to more time-intensive PTSD treatments. The dropout rates for WET have generally been low. Research has examined WET with a variety of trauma samples delivered in diverse settings and in multiple countries using different language translations without modifications to the protocol. Overall, the rapidly growing literature indicates that WET is an effective brief treatment for PTSD that can be used in many different settings. Recommendations for future research include additional studies examining implementation of treatment as well as dissemination work. [ Psychiatr Ann . 2024;54(3):e70–e74.]

EMDR in Three Adults With Severe Intellectual Disability and Posttraumatic Stress Disorder: A Multiple-Baseline Evaluation

Research on trauma treatment in people with severe intellectual disability (SID; IQ 20–35) is scarce, and controlled studies are lacking. This study examined the effectiveness of eye movement desensitization and reprocessing (EMDR) therapy using the storytelling method in three adults with SID and posttraumatic stress disorder (PTSD). A multiple-baseline design was used to examine the effects of EMDR storytelling method on PTSD classification, PTSD symptoms, challenging behaviors, and dysfunctional behaviors in three adults with SID and PTSD. EMDR resulted in a significant decrease in PTSD symptoms, challenging behaviors, and most dysfunctional behaviors. None of the participants had a PTSD classification anymore after EMDR. Findings suggest EMDR to be effective in the treatment of PTSD in adults with SID. Follow-up research with a larger sample size is required.
