This review critically evaluates the existing literature on youth punishment system (YPS)-involved Black girls and their intersections of with trauma and post-traumatic stress disorder (PTSD). It synthesizes findings from previous studies, identifying key research trends, gaps, and controversies, while also highlighting areas in need of further investigation. Black girls, particularly those involved in systems such as juvenile justice, child welfare, and education, often face disproportionate exposure to violence, abuse and neglect, trauma, and systemic racism. For Black girls with histories of trauma and PTSD, these intersecting challenges are compounded by the added vulnerabilities of race, gender, and YPS involvement. This article argues that addressing the complex needs of this population requires recognition that Black girls’ harm is criminalized and, therefore, inextricably linked to their YPS-involvement, so a comprehensive, culturally responsive approach that includes trauma-informed care, healing-centered engagement, and holistic support systems are needed. Equitable access to tailored mental health services, educational resources, and culturally relevant interventions is essential to mitigate the long-term effects of trauma, promote resilience, and foster healing. Additionally, advocacy efforts to dismantle systemic harm and address racial and gender disparities are critical for creating inclusive environments that empower and support Black girls in these systems. By centering their lived experiences, this review emphasizes the importance of fostering environments of healing, justice, and equity for this vulnerable population. Full article

This study aims to explore the current state of research and the applicability of artificial intelligence (AI) at various stages of post-traumatic stress disorder (PTSD), including prevention, diagnosis, treatment, patient self-management, and drug development. We conducted a bibliometric analysis using software tools such as Bibliometrix (version 4.1), VOSviewer (version 1.6.19), and CiteSpace (version 6.3.R1) on the relevant literature from the Web of Science Core Collection (WoSCC). The analysis reveals a significant increase in publications since 2017. Kerry J. Ressler has emerged as the most influential author in the field to date. The United States leads in the number of publications, producing seven times more papers than Canada, the second-ranked country, and demonstrating substantial influence. Harvard University and the Veterans Health Administration are also key institutions in this field. The Journal of Affective Disorders has the highest number of publications and impact in this area. In recent years, keywords related to functional connectivity, risk factors, and algorithm development have gained prominence. The field holds immense research potential, with AI poised to revolutionize PTSD management through early symptom detection, personalized treatment plans, and continuous patient monitoring. However, there are numerous challenges, and fully realizing AI’s potential will require overcoming hurdles in algorithm design, data integration, and societal ethics. To promote more extensive and in-depth future research, it is crucial to prioritize the development of standardized protocols for AI implementation, foster interdisciplinary collaboration—especially between AI and neuroscience—and address public concerns about AI’s role in healthcare to enhance its acceptance and effectiveness.

Background/Objectives: Rodents provide a useful translational model of fear- and anxiety-related behaviors. Previously stressed animals exhibit physiological and behavioral stress responses that parallel those observed in anxious humans. Patients diagnosed with post-traumatic stress disorder (PTSD) present with a spectrum of debilitating anxiety symptoms that result from exposure to one or more traumatic events, with individuals exposed to early adverse experiences and women having increased vulnerability for diagnoses; however, the mechanisms of this increased vulnerability remain unknown. PTSD involves a complex network of highly interconnected brain regions, including the bed nucleus of the stria terminalis (BNST). Serotonin (5-HT) release into the BNST yields an increased expression of both fear and anxiety, specifically through 5-HT_2C receptor signaling. The present experiment addressed whether 5-HT_2C receptor signaling in the BNST is necessary for the acquisition of early-life stress (ELS)-induced enhancements in adult contextual fear learning. Methods: Rats received 0 or 15 footshocks on postnatal day 17, an established model of acute ELS (aELS) that yields enhanced adult fear learning. In adulthood, rats received bilateral infusions of a vehicle, a 5-HT_2C receptor antagonist (RS-102221), or a 5-HT_2C receptor agonist (MK-212) into the BNST 15 min prior to one-footshock contextual fear conditioning in a novel context. The next day, rats were returned to the fear-conditioning context to assess their fear memory (freezing). Results: Females demonstrated aELS-induced enhancement in contextual fear learning, while males did not. BNST infusions of RS-102221 reduced contextual fear conditioning, independent of aELS condition and sex. Infusions of MK-212 had no effect. Conclusions: Taken together, these data suggest that serotonergic signaling through 5-HT_2C receptors in the BNST contributes to contextual fear conditioning, but not aELS-induced stress-enhanced fear learning (SEFL).

Background: Chronobiology has gained attention in the context of paediatric neurological and neuropsychiatric disorders, including migraine, epilepsy, autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and post-traumatic stress disorder (PTSD). Disruptions in circadian rhythms are associated with key symptoms such as sleep disturbances, mood dysregulation, and cognitive impairments, suggesting a potential for chronobiology-based therapeutic approaches. Methods: This narrative review employs a systematic approach to identify relevant studies through searches of three major scientific databases, NCBI/PubMed, ScienceDirect, and Scopus, up to July 2024. We used a combination of broad and condition-specific keywords, such as “chronobiology”, “biorhythm”, “pediatric”, “epilepsy”, “ADHD”, and “ASD”, among others. Articles in English that focused on clinical features, treatments, or outcomes related to circadian rhythms in paediatric populations were included, while non-peer-reviewed articles and studies lacking original data were excluded. Rayyan software was used for article screening, removing duplicates, and facilitating consensus among independent reviewers. Results: A total of 87 studies were included in the analysis. Findings reveal a consistent pattern of circadian rhythm disruptions across the disorders examined. Specifically, dysregulation of melatonin and cortisol secretion is observed in children with ASD, ADHD, and PTSD, with altered circadian timing contributing to sleep disturbances and mood swings. Alterations in core clock genes (CLOCK, BMAL1, PER, and CRY) were also noted in children with epilepsy, which was linked to seizure frequency and timing. Chronotherapy approaches showed promise in managing these disruptions: melatonin supplementation improved sleep quality and reduced ADHD symptoms in some children, while light therapy proved effective in stabilizing sleep–wake cycles in ASD and ADHD patients. Additionally, behaviour-based interventions, such as the Early Start Denver Model, showed success in improving circadian alignment in children with ASD. Conclusions: This review highlights the significant role of circadian rhythm disruptions in paediatric neurological and neuropsychiatric disorders, with direct implications for treatment. Chronobiology-based interventions, such as melatonin therapy, light exposure, and individualized behavioural therapies, offer potential for improving symptomatology and overall functioning. The integration of chronotherapy into clinical practice could provide a paradigm shift from symptom management to more targeted, rhythm-based treatments. Future research should focus on understanding the molecular mechanisms behind circadian disruptions in these disorders and exploring personalized chronotherapeutic approaches tailored to individual circadian patterns.

Introduction: Post-Traumatic Stress Disorder (PTSD) is a highly prevalent disorder and a highly debilitating condition. Although current theories focused on depressed mood and intrusion as critical dimensions, the mechanism through which depression increases the risk of PTSD remains unclear. Research usually concentrates on the hyperactive negative valence system (NVS) (e.g., increased fear and threat responses), but some evidence suggests a significant role for the hypoactive positive valence system (PVS) (e.g., less neural activation towards rewards). Method: The main aim of the present research was to investigate whether probable PTSD leads to a different evaluation of the implicit processing in a refugee’s sample. Ratings of arousal, dominance, and valence from 60 International Affective Picture System (IAPS) pictures (positive, neutral, and negative) were collected from 42 individuals with probable PTSD, and a group of 26 trauma-exposed individuals (M_age = 28.49 years, SD = ±7.78). Results: ANOVA results revealed a main group effect (η2p = 0.379) on arousal, dominance, valence dimensions, and pictures’ categories (η2p = 0.620), confirming evidence according to which PTSD origins a state of maladaptive hyperarousal and troubles the regulation of emotions, and not supporting the view that such difficulties arise only with negative stimuli. Participants with probable PTSD deemed negative stimuli as more threatening than they really are, reacting to unpleasant images with greater negative emotionality (i.e., enhanced arousal and lower valence ratings) compared with individuals without PTSD. Moreover, they rated positive stimuli as less pleasant. Furthermore, arousal ratings were negatively correlated with valence (r = −0.709, p < 0.01) indicating that pictures with high arousal (negative) were associated with lower valence. Discussion: Our findings supported evidence according to which PTSD caused a constant state of hyperarousal and difficulties in regulating emotions facing environmental stimuli. Positive stimuli are considered less pleasant, and this inhibits from completely benefiting from them. Conclusion: Our study provides evidence for a differential and potentially complementary involvement of NVS and PVS in PTSD development. Intervention for PTSD may, thus, target both negative and positive valence processing. Full article

Background and Objectives: Post-traumatic stress disorder (PTSD) is a debilitating condition worldwide. The limited effectiveness of current psychological and pharmacological treatments has motivated studies on meditation techniques. This study is a comprehensive, multiple-treatments meta-analysis comparing the effectiveness of different categories of meditation in treating PTSD. Methods and Materials: We followed Prisma guidelines in our published protocol to search major databases and to conduct a meta-analysis of the studies. Results: We located 61 studies with 3440 subjects and divided them logically into four treatment groups: Mindfulness-Based Stress Reduction (MBSR, 13 studies); Mindfulness-Based Other techniques (MBO, 16 studies), Transcendental Meditation (TM, 18 studies), and Other Meditations that were neither mindfulness nor TM (OM, 14 studies). Trauma populations included war veterans, war refugees, earthquake and tsunami victims, female survivors of interpersonal violence, clinical nurses, male and female prison inmates, and traumatized students. Of those offered, 86% were willing to try meditation. The baseline characteristics of subjects were similar across meditation categories: mean age = 52.2 years, range 29–75; sample size = 55.4, range 5–249; % males = 65.1%, range 0–100; and maximum study duration = 13.2 weeks, range 1–48. There were no significant differences between treatment categories on strength of research design nor evidence of publication bias. The pooled mean effect sizes in Hedges’s g for the four categories were MBSR = −0.52, MBO = −0.66, OM = −0.63, and TM = −1.13. There were no appreciable differences in the study characteristics of research conducted on different meditations in terms of the types of study populations included, outcome measures, control conditions, gender, or length of time between the intervention and assessment of PTSD. TM’s effect was significantly larger than for each of the other categories, which did not differ from each other. No study reported serious side effects. Conclusions: All categories of meditation studied were helpful in mitigating symptoms of PTSD. TM produced clinically significant reductions in PTSD in all trauma groups. We recommend a multisite Phase 3 clinical trial to test TM’s efficacy compared with standard treatment. Full article

Background: glucocorticoids may play an important role in the formation of fear memory, which is relevant to the neurobiology of post-traumatic stress disorder (PTSD). In our previous study, we showed the glucocorticoid receptor (GR) forms a protein complex with FKBP51, which prevents translocation of GR into the nucleus to affect gene expression; this complex is elevated in PTSD patients and by fear-conditioned learning in mice, and disrupting this complex blocks the storage and retrieval of fear-conditioned memories. The timing of release of glucocorticoid relative to the formation of a traumatic memory could be important in this process, and remains poorly understood. Methods and Results: we mapped serum corticosterone over time after fear conditioning in cardiac blood samples from male and female mice, as well as adult and aged mice using ELISA. We show a significant alteration in serum corticosterone after conditioning; notably, levels spike after 30 min but drop lower than unconditioned controls after 24 h. We further investigate the effect of glucocorticoid on GR phosphorylation and localization in HEK 293T cells by Western blot. Hydrocortisone treatment promotes phosphorylation and nuclear translocation of GR. Conclusions: these data contribute to our understanding of the processes linking stress responses to molecular signals and fear memory, which is relevant to understanding the shared mechanisms related to PTSD.

Post-Traumatic Stress Disorder (PTSD) is a multifaceted psychiatric disorder triggered by traumatic events, leading to prolonged psychological distress and varied symptoms. Rat models have been extensively used to explore the biological, behavioral, and neurochemical underpinnings of PTSD. This review critically examines the strengths and limitations of commonly used rat models, such as single prolonged stress (SPS), stress–re-stress (S-R), and predator-based paradigms, in replicating human PTSD pathology. While these models provide valuable insights into neuroendocrine responses, genetic predispositions, and potential therapeutic targets, they face challenges in capturing the full complexity of PTSD, particularly in terms of ethological relevance and translational validity. We assess the degree to which these models mimic the neurobiological and behavioral aspects of human PTSD, highlighting areas where they succeed and where they fall short. This review also discusses future directions in refining these models to improve their utility for translational research, aiming to bridge the gap between preclinical findings and clinical applications.

Background/Objectives: Comorbid post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) patients are at a significantly higher risk of adverse outcomes, including opioid use disorder, depression, suicidal behaviors, and death, yet limited treatment options exist for this population. This study aimed to build on previous research by incorporating drug target information into a novel deep learning model, T-DeepBiomarker, to predict adverse outcomes and identify potential therapeutic medications. Methods: We utilized electronic medical record (EMR) data from the University of Pittsburgh Medical Center (UPMC), analyzing 5565 PTSD + AUD patients. T-DeepBiomarker was developed by integrating multimodal data, including lab results, drug target information, comorbidities, neighborhood-level social determinants of health (SDoH), and individual-level SDoH (e.g., psychotherapy and veteran status). The model was trained to predict adverse events, including opioid use disorder, suicidal behaviors, depression, and death, within three months following any clinical encounter. Candidate medications targeting significant proteins were identified through literature reviews. Results: T-DeepBiomarker achieved high predictive performance with an AUROC of 0.94 for adverse outcomes in PTSD + AUD patients. Several medications, including OnabotulinumtoxinA, Dronabinol, Acamprosate, Celecoxib, Exenatide, Melatonin, and Semaglutide, were identified as potentially reducing the risk of adverse events by targeting significant proteins. Conclusions: T-DeepBiomarker demonstrates high accuracy in predicting adverse outcomes in PTSD + AUD patients and highlights candidate drugs with potential therapeutic effects. These findings advance pharmacotherapy for this high-risk population and identify medications that warrant further investigation. Full article

Sexual shame negatively affects women’s sexual functioning, impacting arousal, desire, orgasm, and pain. This review summarizes the existing literature, highlighting the multiple, interacting factors contributing to sexual shame including sociocultural messages, body and genital self-image, sexual self-schemas, sexual pain, comorbid chronic disease, illness, medical disorders, and sexual trauma. The relationship between sexual shame and sexual functioning is often reciprocal, demonstrating sexual shame as a potential causal and maintaining mechanism underlying women’s sexual difficulties. We present a model proposing the mechanisms by which sexual shame affects sexual functioning, underscoring the need for comprehensive approaches to mitigate the impact of sexual shame and foster sexual well-being for women. Growing research emphasizes emotional processes in models of sexual function, and emotional pathways underlying sexual difficulties and dysfunction. Given the impact of sexual shame on women’s sexual functioning, therapeutic approaches that target sexual shame are recommended to help alleviate difficulties with sexual arousal, desire, orgasm, and sexual pain.

This report presents the follow-up treatment course of a previously published case that demonstrated the effectiveness of prolonged exposure (PE) therapy for a disaster relief worker. The patient, a municipal employee in Fukushima Prefecture, developed post-traumatic stress disorder (PTSD) and mood disorders after the 2011 Great East Japan Earthquake and subsequent disasters. This follow-up focuses on the period from 2021 to early 2024, during which the patient experienced symptom recurrence after his father’s death. This event revealed psychological patterns similar to his disaster-related responses. Schema therapy was introduced to address over-adaptive work behaviors and vulnerabilities in relationships, identified as relapse risk factors. Combined with antidepressants, schema therapy achieved sustained improvement. This longitudinal perspective demonstrates schema therapy’s effectiveness in addressing underlying vulnerabilities when symptoms re-emerge after trauma-focused treatment. The findings underscore how initial trauma responses may interact with subsequent life events and suggest schema therapy’s potential as a secondary intervention for disaster relief workers facing complex challenges.

Background/Objectives: The COVID-19 pandemic has led to increased mental health issues, particularly among long-COVID patients, who experience persistent symptoms post-recovery, potentially leading to chronic conditions. The psychological impact of long-COVID is still largely unknown, but it may contribute to mental disorders like Post-Traumatic Stress Disorder (PTSD). Given the global rise in anxiety and depression, exploring therapies like Eye Movement Desensitization and Reprocessing (EMDR) for long-COVID traumatic disorders is crucial. This study explores the effectiveness of remote EMDR therapy for PTSD-like symptoms in long-COVID conditions (LCC), assessing their emergence, the impact of LCC on mental health, and identifying key commonalities. It also examines the potential advantages of an artificial intelligence (AI)-powered platform for EMDR treatments for both therapists and patients, evaluating the response differences between remote and in-person treatment. Methods: We enrolled a total of 160 participants divided into two groups of 80, with the experimental group receiving EMDR treatment for PTSD-like symptoms via a remote AI-powered platform, and the control group receiving traditional in-person therapy. We compared the ANOVA for Subjective Units of Disturbance (SUDs) scores, PTSD Checklist for DSM-5 (PCL-5) scores, and Impact of Event Scale-Revised (IES-R) scores between our two groups for three cases: pre-treatment, post-treatment, and decrement. Results: Statistical significance analysis showed a consistent absence of significant differences between online AI-powered platforms and traditional in-presence sessions. This effectively confirms our hypothesis and highlights that no significant differences were observed between the two groups. Conclusions: The AI-supported remote platform demonstrates comparable efficacy in delivering EMDR therapy, confirming its potential as an effective alternative to traditional in-person methods while providing added advantages in accessibility and adaptability (e.g., remote areas, hikikomori, natural disasters).

Background/Objectives: The aim of this study was to determine if performing ultrasound-guided, bilateral, two-level cervical sympathetic chain blocks (2LCSBs) (performed on subsequent days) improves symptoms associated with traumatic brain injury (TBI) that do not overlap with posttraumatic stress disorder (PTSD). Methods: A retrospective chart review was conducted between August 2022 and February 2023. We identified twenty patients who received bilateral 2LCSBs for PTSD and anxiety symptoms and who also had a history of TBI. Neurobehavioral Symptom Inventory (NSI) scores were collected at baseline, one week, and one month post treatment in 13 males and 7 females. A sub-analysis of the first ten questions of the NSI, which we identified as not overlapping with PTSD or anxiety symptoms, generated an NSI sub-score. Results: Out of 20 patients, all showed improvement in their NSI scores and NSI sub-scores. The NSI sub-scores had a baseline average of 15.45 (on a 40-point scale); the average score at one week post treatment was 8.30; and that at one month post treatment was 7.80. This represents a 49.51% improvement in TBI symptoms which did not overlap with PTSD or anxiety symptoms between baseline and one month. Conclusions: The use of bilateral 2LCSBs may be helpful in treating patients with TBI, regardless of the presence of comorbid PTSD symptoms. Full article

Adverse childhood experiences (ACEs) have already been associated, in some studies, with various diverse psychosocial abnormalities in later life. However, it is still unclear whether ACEs reported by biological parents differ from ACE scores in community samples. Background/Objectives: The aim of this study was to investigate the extent to which parents of a patient sample differ from a community sample in terms of reporting childhood experiences. In addition, the connection between parental negative traumatic experiences and their children’s reporting of these experiences should be examined in more detail. Methods: In total, 256 child psychiatric patients (73.8% female and 26.2% male) aged 4–18 years (mean [M] = 13.26 years, standard deviation [SD] = 2.73) were retrospectively examined for post-traumatic stress symptoms (using the CATS questionnaire). In addition, 391 caregivers, 316 of whom were biological parents, completed the ACE questionnaire on adverse childhood experiences. The frequencies of ACEs of the parents, the traumatic experiences of the patients and their cumulative occurrence were evaluated descriptively. Results: A total of 139 (73%) mothers reported at least one negative experience in childhood. In contrast, 65 fathers (52%) reported at least one negative experience in childhood. Mothers most frequently mentioned separation from a parent (38.7%), while fathers cited emotional abuse as the most frequent negative experience. These ACE scores were significantly higher than those reported from community samples. Post-traumatic stress disorder was diagnosed in 75 (29.3%) of the 256 patients. A total of 44.6% of children of mothers and 53.8% of children of fathers reporting at least one ACE showed a CATS score above the cut-off. Conclusions: Parents of child psychiatric patients show higher scores of adverse childhood experiences than a community sample with the same population background. Further empirical studies in parents of child psychiatric patients and a larger sample seem mandatory in the face of these results. Full article

Background: The COVID-19 pandemic has significantly impacted the mental health of healthcare professionals, particularly nurses and paramedics. This study investigates the prevalence of Post-Traumatic Stress Disorder (PTSD) and the impact of social ostracism on psychological distress among healthcare workers (HCWs) in Poland, with a focus on exploring the interplay between professional and social factors contributing to their stress. Methods: A cross-sectional survey was conducted between March 2021 and February 2022 with 852 HCWs from four Polish provinces. PTSD symptoms were measured using the PTSD Checklist—Civilian Version (PCL-C), and social ostracism was assessed through a custom-designed questionnaire. Results: Of the participants, 14.1% reported experiencing social ostracism, and 4.9% observed such experiences among colleagues. Those who experienced or witnessed ostracism reported significantly higher PTSD symptoms (p < 0.001). Concerns about personal health and the well-being of older individuals were strongly associated with increased PTSD severity, while concerns for household members were not. Conclusions: Social ostracism exacerbates the psychological burden on healthcare workers, contributing to higher levels of PTSD. This study highlights the need for targeted mental health interventions and support systems, including resilience training and stigma reduction initiatives, to address these challenges. Future research should explore cross-national comparisons and long-term psychological effects among diverse healthcare populations. Full article
