Ketamine is a promising treatment for post-traumatic stress disorder (PTSD), but further research is required to extend early findings.
Aims
To determine the short-term efficacy and tolerability of intramuscular (i.m.) ketamine compared with i.m. fentanyl for treatment-resistant PTSD symptoms.
Method
We completed a randomised double-blind psychoactive-controlled study with single doses of i.m. racemic ketamine 0.5 mg/kg or 1.0 mg/kg or i.m. fentanyl 50 μg (psychoactive control). Eligible participants were aged between 18 and 50 years old and had treatment-refractory PTSD. The primary efficacy measure was the Impact of Events Scale – Revised (IESR), and tolerability was measured with the Clinician-Administered Dissociative States Scale. Analysis of variance with dose and time as repeated measures was used to assess the effects of drug treatment on total IESR and Clinician-Administered Dissociative States Scale scores.
Results
Thirty-three participants completed the study (26 females, mean age 34.5 years). Ketamine, particularly at 1 mg/kg, was associated with substantially reduced IESR ratings, with some effect remaining after 1 week. Ketamine was also associated with short-term dissociative and cardiovascular effects.
Conclusions
We provide preliminary support for the efficacy and tolerability of i.m. ketamine in a community sample of individuals with PTSD. Further work is required to establish the optimal dosing regimen and longer-term role of ketamine in treatment of PTSD, but our findings are encouraging given the well-known of treatments in this area.

Chapter 18 covers the topic of acute stress disorder, post-traumatic stress disorder and adjustment disorder. Through a case vignette with topical MCQs for consolidation of learning, readers are brought through the diagnosis and treatment of a patient with acute stress disorder, post traumatic stress disorder and adjustment disorder. Topics covered include diagnosis and differential diagnoses of acute stress disorder, risk factors, management, prognosis, complications and childhood sexual abuse and its management.
Dissociative disorders frequently co-occur with post-traumatic stress disorder (PTSD), yet many individuals lack adequate treatment. Existing interventions often prioritise reducing arousal over promoting safety and self-soothing, tending to neglect the bodily experience.
Aims
This randomised clinical within-person pilot study examined the effects of the nest position, a physiotherapeutic intervention designed to enhance safety and self-soothing, on patients with dissociative disorders and healthy controls (German Clinical Trials Register No.: DRKS00030669).
Method
Eighteen patients with dissociative disorders and 18 healthy controls alternated between the nest position and a neutral supine position across two rounds of a measurement session. The order of the experimental conditions (nest position or supine only) was randomised for each participant. We assessed self-reported distress and comfort (Subjective Units of Distress and Comfort) and autonomic nervous system activity during three baseline phases and imagination of stressful and comforting situations.
Results
Both patients and healthy controls experienced lower distress and greater comfort in the nest position. Heart rate and sympathetic tone decreased, particularly in the healthy controls. There were no significant changes in parasympathetic tone in both groups. Linear mixed models revealed a significant effect of the nest position on distress, comfort and sympathetic tone.
Conclusions
The nest position is a potentially promising additional intervention for highly dissociative patients. Our findings help to better understand the importance of self-soothing and safety in these individuals and to address the research gap in physiotherapy within in-patient mental health care.
This paper describes subgroup analyses of a recent real-world study examining the impact of esketamine nasal spray combined with a newly initiated oral antidepressant (OAD) on quality-of-life and depression severity in participants with treatment-resistant depression (TRD). Patients with TRD, defined as major depressive disorder in adults who have not responded adequately to ≥2 different OADs of adequate dose and duration to treat the current depressive episode, were recruited from the esketamine early access program in Australia and New Zealand. Subgroups were defined by prior antidepressant medications received in the current depressive episode (2, 3–5, or ≥6) and post-traumatic stress disorder (PTSD) or anxiety disorder comorbidity (with or without). Comorbid PTSD or anxiety disorder was identified by treating psychiatrists. Outcome measurements included Assessment of Quality-of-Life (AQoL-8D) and Hamilton Depression Rating (HAM-D) scales. From baseline to Week 16, all subgroups saw significant improvements in AQoL-8D and HAM-D. There was no statistical difference between outcome improvements for participants with or without comorbid anxiety or PTSD. When separated by prior therapy, participants with 2 prior therapies demonstrated the greatest outcome improvements. Real-world esketamine treatment in conjunction with a newly initiated OAD benefits real-world participants with TRD and comorbid anxiety or PTSD, regardless of previously failed treatments.
Near-death experiences often have pervasive and long-lasting aftereffects in the lives of the affected persons. These aftereffects may concern personal attitudes to their own death, beliefs and spiritual life, social relationships, and other important aspects of life such as health care and work. Despite hundreds of collected and analyzed NDE reports, in the publications of many NDE researchers there is no discussion of such aftereffects that take a scientific perspective on NDE phenomena. From a scientific point of view, we can attest stagnation in the field of most NDE research. This stagnation will continue as long as researchers remain in the mental tradition of Moody, misinterpreting or ignoring studies on brain activity in metabolic stress, on brain physiology in the progression to brain death, and on the relationship between levels of consciousness and signatures in electroencephalograms.
The high comorbidity of major depressive disorder (MDD), anxiety disorders (ANX), and post-traumatic stress disorder (PTSD) complicates the study of their structural neural correlates, particularly in white matter (WM) alterations. Using fractional anisotropy (FA), this meta-analysis aimed to identify both unique and shared WM characteristics for these disorders by comparing them with healthy controls (HC). The aggregated sample size across studies includes 3,661 individuals diagnosed with MDD, ANX, or PTSD and 3,140 HC participants. The whole-brain analysis revealed significant FA reductions in the corpus callosum (CC) across MDD, ANX, and PTSD, suggesting a common neurostructural alteration underlying these disorders. Further pairwise comparisons highlighted disorder-specific differences: MDD patients showed reduced FA in the middle cerebellar peduncles and bilateral superior longitudinal fasciculus II relative to ANX patients and decreased FA in the CC extending to the left anterior thalamic projections (ATPs) when compared with PTSD. In contrast, PTSD patients exhibited reduced FA in the right ATPs compared to HC. No significant FA differences were observed between ANX and PTSD or between ANX and HC. These findings provide evidence for both shared and unique WM alterations in MDD, ANX, and PTSD, reflecting the neural underpinnings of the clinical characteristics that distinguish these disorders.
Decades of systemic oppression in Syria, from the 1963 state of emergency to the 2011–2024 conflict, have caused widespread psychological devastation. Arbitrary imprisonment, torture and sexual violence have been systematically weaponised. Following the fall of the Syrian regime in December 2024, freed political prisoners face severe mental health challenges due to years of inhumane conditions and trauma. This paper emphasises the urgent need for specialised mental health interventions and outlines evidence-based pathways to healing. A coordinated, multi-tiered response, integrating local and international efforts, is essential to prioritise mental health aid, restore dignity and support survivors in rebuilding their futures.
We aimed to reveal the psychological effects of old and young individuals after the earthquake by looking at their post-traumatic stress disorder (PTSD) and depression situations.
Methods
Data collected by face-to-face survey method were analyzed. The 4 provinces (Hatay, Kahramanmaraş, Adıyaman, and Gaziantep) most affected by the 7.7 and 7.6 magnitude earthquakes centered in Kahramanmaraş, Turkey on February 6, 2023 were included in the study. Peritraumatic distress inventory, impact of events scale, and Beck depression inventory were applied to 300 people (150 old, 150 young).
Results
The presence of peritraumatic stress was observed in 94% (282 people), PTSD symptoms in 90% (270 people) and moderate to severe depression in 36.7% (110 people). When younger were compared with those elders, it was concluded that there was no significant difference in terms of presence of peritraumatic distress (49.6% vs. 50.4%, P=0.627), PTSD (49.6% vs. 50.4%, P=0.620) and moderate to severe depression (45.5% vs. 54.5%, P=0.258).
Conclusions
We found similar rates of PTSD and depression symptoms in older and younger adults exposed to earthquakes. Policies need to be developed to ensure psychological well-being after an earthquake disaster in the adult population regardless of age group.
This study aims to investigate the relationship between post-traumatic stress disorder (PTSD) and job-related stress among nurses working in both central and district areas of Adıyaman following the earthquake. Additionally, we assess potential risk factors influencing both PTSD and job-related stress.
Methods
This cross-sectional study involved 332 nurses. The study considered several independent variables, including age, gender, marital status, place of residence, experience of family loss due to the earthquake, and workplace location. The dependent variables for the study were identified as post-traumatic stress disorder and job stress.
Results
Of the nurses surveyed, 69% showed symptoms of post-traumatic stress disorder.
Notably, higher job stress scale scores were identified among women (P = 0.028), married individuals (P = 0.005), those with children (P < 0.001), those who were in Adıyaman during the earthquake (P < 0.001), and those who experienced family loss due to the earthquake (P < 0.001). Furthermore, a significant positive correlation was observed between PTSD scores and job stress scores (r = 0.599; P < 0.001).
Conclusions
Given the bidirectional impact of PTSD and job stress, prompt and comprehensive interventions are essential for safeguarding nurses’ mental health and professional capacity following major events. These interventions should also consider other risk factors, such as female gender or experiencing a family loss.
A minority of earthquake-exposed individuals develop post-traumatic stress disorder (PTSD), often alongside comorbid depression and anxiety symptoms. No systematic review has examined psychological interventions for adults with substantial earthquake-related PTSD symptoms.
Aims
To synthesise studies evaluating psychological interventions for adult earthquake-related PTSD and conduct meta-analyses estimating overall effect sizes.
Method
The review was pre-registered with PROSPERO (CRD42023441020). PsycINFO, MEDLINE, EMBASE, CINAHL and Scopus were searched for studies (last search conducted July 2024). Randomised controlled trials (RCTs), non-randomised and non-controlled studies evaluating psychological interventions for adults with substantial earthquake-related PTSD symptoms were eligible. Outcomes were PTSD, depression and anxiety symptoms. Narrative syntheses and meta-analyses summarised study findings. The Mixed Methods Appraisal Tool guided quality assessments.
Results
Sixteen studies were identified (eight RCTs, four non-randomised and four non-controlled studies), representing 1315 participants receiving psychological intervention. Interventions included cognitive behavioural therapy (CBT), specific CBT variants, eye movement desensitisation and reprocessing, interpersonal psychotherapy and an internet-based intervention focusing on social cognitive theory. Studies generally reported statistically and clinically significant improvements associated with psychological interventions. Among studies included in meta-analyses, overall effect size was 2.11 (95% CI = 0.92, 3.31) for PTSD symptoms and 1.01 (95% CI = 0.50, 1.52) for depression symptoms.
Conclusions
Psychological interventions are associated with good outcomes among adults with earthquake-related PTSD. The most evidence currently exists for CBT-based interventions, which are recommended as first-line treatments. Efficient intervention options, including single-session and group-based treatments, also show promise and are recommended for addressing widespread treatment need.
We studied posttraumatic stress symptoms (PTSS) and disorder (PTSD), associated factors, and quality of life (QOL) of a group of passengers (n = 58) affected by the 2023 Odisha train accident, comparing it with health professionals (n = 42) such as doctors and nurses who treated them, and individuals from the local community (n = 65). We also checked the anxiety and depression of passengers.
Methods
In a cross-sectional study, we assessed accident experience and used the PTSD checklist, WHO-QOL-BREF, General Anxiety Disorder, and Patient Health Questionnaire scales.
Results
The PTSS were common; specifically, intrusive memories (36.4%), feeling upset while reminded of the experience (33.9%), and avoidance of memories (30.9%). Strong negative feelings, loss of interest, feeling distant, and irritability or anger outbursts were significantly more common among passengers than others. PTSD was present in 20.7% of passengers, 19.0% of health professionals, and 7.7% of local participants. Seeing dead bodies significantly contributed to PTSD. Clinical levels of anxiety (58.3%) and depression (50%) were present in passengers, which were significantly associated with PTSD, along with fear of death. Passengers had the worst QOL and health satisfaction among the groups.
Conclusions
Following the train accident, stress-related psychiatric problems were common and highlighted the intervention needs of the affected people.
One in 25 patients experience PTSD following childbirth. Risk factors include unplanned cesarean delivery, operative vaginal delivery, obstetric emergencies such as cord prolapse, neonatal intensive care admission, previous trauma, and severe physical complications. Early recognition of PTSD is imperative. It can have a significant impact on the health of both the birthing parent and the infant. It is associated with difficulty in bonding with the infant, breast-feeding, or engaging in postnatal care. A multidisciplinary approach between obstetricians, psychiatrists, and other mental health providers is recommended for management. Treatment may involve eye movement desensitization and reprocessing, cognitive behavioral therapy, and pharmacotherapy. It is reasonable to perform cesarean delivery for maternal request in patients who are well informed of the risks, benefits, and alternatives.
Traumatic experiences can trigger post-traumatic stress disorder (PTSD) and influence one’s future perspective, which can change over time with the sense of control.
Aims
We measured changes in predictions about the future among individuals who experienced a traumatic event, with or without PTSD, according to their sense of control, and its relationship with post-traumatic change (post-traumatic stress symptom severity, well-being and coping strategies).
Method
Eighty-one exposed individuals (who experienced the 2015 Paris terrorist attacks), some with PTSD, and 71 non-exposed controls (who had not experienced the attacks) were asked to estimate the probable future occurrence of 20 controllable and 20 uncontrollable events, 7–18 and 31–43 months after the attacks. Repeated-measures analysis of variance and correlations were performed to measure inter-group differences in outcomes and relationships with post-traumatic change.
Results
Exposed participants with PTSD and without PTSD estimated uncontrollable future events to be more likely over time. Uncontrollable predictions were related to increases in post-traumatic stress symptom severity for individuals without PTSD. Uncontrollable predictions were not correlated with well-being or coping in exposed individuals.
Conclusions
Over time, exposed individuals provide increasingly high probability ratings for the future occurrence of uncontrollable events, a tendency associated with an increase in post-traumatic stress symptom severity in exposed individuals without PTSD. This may reflect potential delayed PTSD symptoms over time in individuals who did not initially develop PTSD following the attacks. The range of the measurements and the use of a self-constructed questionnaire limit the internal validity of the results.
High rates of trauma exposure among patients with severe mental illness (SMI) in Botswana highlight the need for appropriate interventions. Culturally adapted interventions have been reported to be more acceptable, effective and feasible. This study aimed to culturally adapt the Brief Relaxation, Education and Trauma Healing (BREATHE), a brief psychological intervention to treat post-traumatic stress disorder (PTSD) among people with SMI in Botswana. The cultural adaptation process followed the steps outlined by previous research. They included a community assessment to identify needs, selecting an appropriate intervention and consultations with experts and stakeholders. Individual interviews and focus groups were conducted with patients living with SMI and mental health professionals, respectively, to inform domains of the intervention to be adapted. BREATHE was adapted to be culturally congruent to Botswana by following the ecological validity model framework and using data from the interviews. Examples of the adaptation include language that was translated to Setswana, and spoken English and the content that was revised to reflect the traumatic experiences and demographics of the Botswana population. The study underscores the utility of using evidence-based frameworks to culturally adapt interventions. The adaptation process resulted in a culturally relevant BREATHE for patients with comorbid PTSD and SMI in Botswana.
Post-traumatic stress disorder (PTSD) and hypertension are highly prevalent among Veterans. Cognitive dispersion, indicating within-person variability across neuropsychological measures at one time point, is associated with increased risk of dementia. We examined interactive effects of PTSD symptom severity and hypertension on cognitive dispersion among older Veterans.
Methods:
We included 128 Vietnam-era Veterans from the Department of Defense-Alzheimer’s Disease Neuroimaging Initiative (DoD-ADNI) with a history of PTSD. Regression models examined interactions between PTSD symptom severity and hypertension on cognitive dispersion (defined as the intraindividual standard deviation across eight cognitive measures) adjusting for demographics and comorbid vascular risk factors.
Results:
There was an interaction between PTSD symptom severity and hypertension on cognitive dispersion (p = .026) but not on mean cognitive performance (p = .543). Greater PTSD symptom severity was associated with higher cognitive dispersion among those with hypertension (p = .002), but not among those without hypertension (p = .531). Results remained similar after adjusting for mean cognitive performance.
Conclusions:
Findings suggest, among older Veterans with PTSD, those with both hypertension and more severe PTSD symptoms may be at greater risk for cognitive difficulties. Further, cognitive dispersion may be a useful marker of subtle cognitive difficulties. Future research should examine these associations longitudinally and in a diverse sample.
Economic variables such as socioeconomic status and debt are linked with an increased risk of a range of mental health problems and appear to increase the risk of developing of post-traumatic stress disorder (PTSD). Previous research has shown that people living in more deprived areas have more severe symptoms of depression and anxiety after treatment in England’s NHS Talking Therapies services. However, no research has examined if there is a relationship between neighbourhood deprivation and outcomes for PTSD specifically. This study was an audit of existing data from a single NHS Talking Therapies service. The postcodes of 138 service users who had received psychological therapy for PTSD were used to link data from the English Indices of Deprivation. This was analysed with the PCL-5 measure of PTSD symptoms pre- and post-treatment. There was no significant association between neighbourhood deprivation measures on risk of drop-out from therapy for PTSD, number of sessions received or PTSD symptom severity at the start of treatment. However, post-treatment PCL-5 scores were significantly more severe for those living in highly deprived neighbourhoods, with lower estimated income and greater health and disability. There was also a non-significant trend for the same pattern based on employment and crime rates. There was no impact of access to housing and services or living environment. Those living in more deprived neighbourhoods experienced less of a reduction in PTSD symptoms after treatment from NHS Talking Therapies services. Given the small sample size in a single city, this finding needs to be replicated with a larger sample.
Key learning aims
(1) Previous literature has shown that socioeconomic deprivation increases the risk of a range of mental health problems.
(2) Existing research suggests that economic variables such as income and employment are associated with greater incidence of PTSD.
(3) In the current study, those living in more deprived areas experienced less of a reduction in PTSD symptoms following psychological therapy through NHS Talking Therapies.
(4) The relatively poorer treatment outcomes in the current study are not explained by differences in baseline PTSD severity or drop-out rates, which were not significantly different comparing patients from different socioeconomic strata.
Post-traumatic stress disorder (PTSD) is a mental health condition caused by the dysregulation or overgeneralization of memories related to traumatic events. Investigating the interplay between explicit narrative and implicit emotional memory contributes to a better understanding of the mechanisms underlying PTSD.
Methods
This case–control study focused on two groups: unmedicated patients with PTSD and a trauma-exposed control (TEC) group who did not develop PTSD. Experiments included real-time measurements of blood oxygenation changes using functional near-infrared spectroscopy during trauma narration and processing of emotional and linguistic data through natural language processing (NLP).
Results
Real-time fNIRS monitoring showed that PTSD patients (mean [SD] Oxy-Hb activation, 0.153 [0.084], 95% CI 0.124 to 0.182) had significantly higher brain activity in the left anterior medial prefrontal cortex (L-amPFC) within 10 s after expressing negative emotional words compared with the control group (0.047 [0.026], 95% CI 0.038 to 0.056; p < 0.001). In the control group, there was a significant time-series correlation between the use of negative emotional memory words and activation of the L-amPFC (latency 3.82 s, slope = 0.0067, peak value = 0.184, difference = 0.273; Spearman’s r = 0.727, p < 0.001). In contrast, the left anterior cingulate prefrontal cortex of PTSD patients remained in a state of high activation (peak value = 0.153, difference = 0.084) with no apparent latency period.
Conclusions
PTSD patients display overactivity in pathways associated with rapid emotional responses and diminished regulation in cognitive processing areas. Interventions targeting these pathways may alleviate symptoms of PTSD.
The post-traumatic stress disorder (PTSD) diagnosis encompasses heterogeneous presentations, many of the diagnostic criteria are not trauma-related and almost all PTSD symptoms are common to several psychiatric diagnoses. Flashbacks are the only symptom unique to PSTD. However, the absence of a consensus definition of flashbacks means that this term means different things to different people, causing misunderstanding and miscommunication, and presumably affecting treatment. This Refreshment discusses how flashbacks are defined in DSM-5-TR and ICD-11 (essentially, as reliving/re-experiencing when awake) and briefly describes the dual representation theory's account of flashbacks. In discussing what flashbacks are and are not, it aims to promote improved understanding, assessment and diagnosis of PTSDs.
This study aimed to investigate the psychological impact of the Turkey 2023 earthquakes on preschool-aged children and to compare them with those with other life-threatening traumas. Thirty-four preschool children who experienced earthquakes on February 6, 2023, and applied to our outpatient clinic in the following 3 months, and 37 other trauma-experienced preschool children were included in this cross-sectional study. Preschool Age Psychiatric Assessment/Post-Traumatic Stress sections were conducted. Parents were asked to complete the Pediatric Emotional Distress Scale and the Child Behavior Checklist for Ages 1.5–5 to evaluate stress-related reactions alongside psychiatric problems of children. The results showed that acute stress disorder and post-traumatic stress disorder (PTSD) were more common in the earthquake-experienced group than in the other trauma-experienced group (Fisher’s exact test, 52.9% vs. 8.1%, p < 0.001 and 38.2% vs. 8.1%, p = 0.004, respectively). Migration after the earthquake had no additional impact on trauma-related psychiatric outcomes, either ASD or PTSD (p = .153, and p = 0.106, respectively); whereas sleep problems predicted PTSD (OR = 1.26, β = 0.42, p = 0.036) in the earthquake-experienced group. Our study provides implications for understanding the psychological impact of earthquakes and risk factors for PTSD among preschool children.
