PTSD - Post Traumatic Stress Disorder

The Redefine Study (COMP202) is testing COMP360 to see if it may reduce post-traumatic stress disorder (PTSD) symptoms when administered alongside monitoring and support from a trained study team. COMP360 is a lab-made form of the naturally occurring chemical compound psilocybin.

The goal of this clinical trial is to evaluate the safety and effectiveness of the gammaCore non-invasive vagus nerve stimulation (nVNS) device as an additional treatment for symptoms of post-traumatic stress disorder (PTSD) in adults. The vagus nerve connects the brain with many organs and systems in the body and plays a role in regulating stress and emotional responses. The gammaCore device is a handheld, rechargeable medical device that delivers gentle electrical stimulation to the vagus nerve through the skin on the side of the neck. By stimulating this nerve, the device may help reduce PTSD symptoms. gammaCore is cleared by the U.S. Food and Drug Administration (FDA) for the treatment and prevention of migraine and cluster headache. It has not yet been approved for the treatment of PTSD. This study is being conducted to better understand whether this type of stimulation may help improve PTSD symptoms and to evaluate its safety when used for this purpose. The main questions this study aims to answer are: * Is non-invasive vagus nerve stimulation safe for people with PTSD when used regularly at home? * Does treatment with the gammaCore device improve PTSD symptom severity over time? In this study, approximately 40 adults with PTSD will participate in an open-label pilot study. Participants will first complete a 4-week baseline period in which their PTSD symptoms are monitored. This allows researchers to understand each participant's symptoms before starting the intervention. Participants will then begin a 12-week treatment period using the gammaCore device at home. During this time, participants will apply the device to the side of the neck for short stimulation sessions each day as instructed by the study team. Participants will attend six study visits, some conducted remotely and some in person. These visits include screening, training on how to use the device, and follow-up assessments. During the study, participants will complete questionnaires and clinician-administered assessments that measure PTSD symptoms and quality of life. Researchers will also monitor participants for any side effects or medical problems related to the device. By collecting information on symptoms, safety, and device use, this study will help researchers understand whether non-invasive vagus nerve stimulation could become a useful treatment option for people living with PTSD.

The goal of this clinical trial is to validate an artificial intelligence algorithm called CAUD-PIN (CAUchemar Detection on INdividualized Parameters) to predict nightmare-related awakenings in military personnel and veterans suffering from post-traumatic stress disorder (PTSD). The main question it aim to answer is : * Can the CAUD-PIN algorithm detect physiological patterns preceding trauma-related nightmare awakenings with a sensitivity greater than 80%? * What physiological signals best predict the occurrence of a trauma-related nightmare awakening? Participants will: Wear two non-invasive devices at home - an EEG headband and a wrist-worn sensor bracelet - for 15 consecutive nights Press a button on the bracelet each time they wake up from a nightmare Complete sleep and daytime diaries every evening and morning Attend two clinical assessments (at enrollment and at the end of the study, one month later) at one of the three participating military hospitals The algorithm will be applied to the recorded data after collection and does not intervene in real time or affect participants' standard medical care in any way.

The goal of this study is to examine changes in cognitive functioning and post-concussive symptoms following hyperbaric oxygen therapy (HBOT) in current and former first responders with a history of traumatic brain injury. The main questions it aims to answer are: 1. Do cognitive functioning and post-concussive symptoms change after 40 HBOT sessions? 2. Do symptoms of PTSD, depression, and anxiety, or quality of life, change after treatment? Approximately 54 participants will: * Complete medical and behavioral health screening. * Complete cognitive tests and questionnaires before and after treatment. * Receive 40 HBOT sessions at 2.0 atmospheres absolute (ATA), twice daily with at least four hours between sessions. All participants will receive HBOT. There is no comparison group, so the study cannot determine whether HBOT caused any observed changes.

In this study, researchers are examining the best sequence of interventions for posttraumatic stress disorder (PTSD) and tinnitus. Participants will either receive psychotherapy for PTSD first (Cognitive Processing Therapy; CPT), followed by treatment for tinnitus (Cognitive Behavioral Therapy for Tinnitus; CBT-t); or vice-versa. We also aim to identify changes in brain functioning after receiving therapy.

Emergency trauma surgery patients, due to the dual stress effects of sudden trauma events (such as car accidents, falls, engineering accidents) and surgical trauma, have a significantly higher incidence of post-traumatic stress disorder (PTSD) compared to the general population. This disease, characterized by intrusive memories, avoidance behaviors, negative changes in cognitive emotions, and increased arousal, not only severely hinders patients' postoperative psychological recovery and reduces their quality of life, but may also prolong hospital stays, increase the risk of readmission, and impose a heavy medical and economic burden on families and society. Dexmedetomidine, as a highly selective α₂-adrenergic receptor agonist, possesses sedative, anxiolytic, analgesic, and sympatholytic effects. By regulating the locus coeruleus-norepinephrine system, it can alleviate perioperative stress responses, reduce postoperative anxiety and delirium incidence. In recent years, multiple studies both domestically and internationally have confirmed its potential to prevent PTSD by inhibiting the encoding and consolidation processes of trauma-related memories. In randomized clinical trials, administering dexmedetomidine during and after surgery has been shown to reduce the incidence of PTSD in trauma patients. However, when used alone, some patients still develop PTSD, indicating room for improvement in preventive efficacy. Additionally, there are risks of adverse reactions such as hypotension and bradycardia, which limit its application in certain populations. As a non-invasive vagus nerve stimulation technique, transcutaneous vagus nerve stimulation (taVNS) exerts its effect by stimulating the vagus nerve branches in the cavum concha. It has the advantages of simple operation, high safety, and can be implemented during the perioperative period. It has been proven to regulate the stress response and emotional processing of the central nervous system, reduce stress response scores, and has the potential for perioperative analgesia. However, there is limited research on its early prevention after emergency trauma surgery, and no exploration of synergistic effects with dexmedetomidine. Currently, there is no clinical research on the use of dexmedetomidine combined with taVNS for the prevention of post-traumatic stress disorder (PTSD) in patients undergoing emergency trauma surgery at home and abroad. Existing research mostly focuses on single drugs or single neuroregulation techniques, and there are limitations such as small sample size, short follow-up time, and uncontrolled confounding factors such as perioperative pain and delirium, making it difficult to meet the clinical demand for efficient and safe PTSD prevention schemes.

This study is a randomized controlled pilot examining the implementation of an adapted intervention, Skills Training in Affective and Interpersonal Regulation-Narrative Therapy (STAIR-NT), among a first responder population with a history of TBI and PTSD.

This research study tests strategies to train behavioral health providers in Written Exposure Therapy (WET), an evidence-based treatment for posttraumatic stress disorder (PTSD). There are a number of evidence-based treatments for posttraumatic stress disorder (PTSD). However, most behavioral health providers have not received training in these PTSD treatments and do not offer them regularly to their patients. The researchers hope to learn about the optimal way to train behavioral providers in this type of treatment. This study is designed to determine the comparative effectiveness of different training strategies on key outcomes such as how much competency providers develop in the therapy and to how many patients they deliver the therapy. This study will help the researchers understand if we can help more providers learn to competently delivery Written Exposure Therapy by using strategies that are more convenient and cost less money, including web-based and AI-facilitated training supports. This study will also help us learn which training strategies work best for which providers so that in the future we can make personalized training recommendations.

The aim of this study is to examine the feasibility and tolerability of a one-day protocol of repetitive transcranial magnetic stimulation with D-cycloserine (DCS) as an augmentation strategy in military personnel and veterans who have PTSD.

A new method is being tested to assist individuals in Ukraine with Post-Traumatic Stress Disorder (PTSD), including veterans and civilians affected by war. The study is a collaboration among Ukrainian healthcare institutions and the Charité Berlin. What is PTSD? PTSD can occur after a distressing or traumatic experience, such as exposure to war. It can result in persistent negative memories, nightmares, heightened nervousness, or avoidance of reminders associated with the event. Purpose of the Study Two innovative treatments for PTSD are being tested: 1. Virtual Reality Therapy: This approach uses specialized goggles to create a safe and realistic virtual environment where individuals can confront memories and process emotions with guidance from a therapist. 2. Brain Stimulation Therapy (tDCS): This method applies a gentle electrical current to the scalp to support improved emotional regulation by the brain. The study aims to determine whether combining these two treatments is more effective than using virtual reality therapy alone. Participant Involvement Participants will: * Attend 10 therapy sessions over several weeks. * Use virtual reality goggles to engage with safe scenarios related to their memories, guided by a therapist. * Potentially receive brain stimulation therapy during some virtual reality sessions. * Learn relaxation techniques to help manage stress and enhance emotional control. Potential Benefits for Participants * These treatments may reduce symptoms such as intrusive memories, anxiety, and depression. * Participants may experience increased calmness, resilience, and improved ability to manage daily life. This study also has the potential to advance PTSD treatment methods for others in the future.

This project aims to evaluate Restory - a newly developed anonymous, iCBT prolonged exposure therapy program specifically tailored for victims of sexual abuse - using a pre-registered randomized controlled trial with waitlist control. The primary research question is whether Restory is more effective than a waitlist control in reducing PTSD symptom severity score, as measured by PCL-5.

PRE-EMPT will assemble a cohort of 150 participants from three populations (low risk, intermediate risk, and high risk for self-harm). We will obtain clinical assessments, structural and functional MRI utilizing tasks pioneered by our team to assess cognitive control (CC) and emotion regulation (ER), and peripheral circular RNA (circRNA) levels to characterize the molecular brain states associated with behavioral risk. The clinical, imaging, and transcriptomic data will be fused and jointly analyzed to increase the accuracy of our risk prediction models. PRE-EMPT in three separate Aims will then prospectively assess three promising and innovative interventions for their potential to reduce suicidal ideation and alter activity in key neural networks: 1) neurofeedback (NF) using real-time fMRI with simultaneous electroencephalography (EEG), 2) a form of transcranial magnetic stimulation (TMS) called accelerated intermittent theta burst stimulation (aiTBS) with dose optimization through electric field modeling; and 3) psilocybin assisted therapy (PSI), with flexible dosing plan to maximize the depth of psychedelic experience. These therapies were chosen based on our team's prior work in all three interventions demonstrating rapid action and large effects.

Intimate partner violence (IPV) can have serious and lasting effects on women's mental health and well-being. Chinese immigrant women in the United States often face additional barriers to obtaining IPV and mental health support, including language, cultural, and social challenges. There is a need for culturally appropriate interventions that improve access to care and address the mental health needs of this underserved population. The purpose of this study is to evaluate the efficacy of the Self-Compassion, Health, and Empowerment (SHE) intervention, a culturally tailored mobile health (mHealth) program designed for Chinese immigrant women experiencing IPV. Participants will be randomly assigned to either the SHE intervention or an attention control program and will complete study assessments over a 12-month follow-up period. The results of this study will help determine whether the SHE intervention improves mental health and well-being among Chinese immigrant women experiencing IPV and may provide evidence for an accessible, culturally appropriate intervention that can be implemented more broadly.

This study tests a new brain stimulation treatment for post-traumatic stress disorder (PTSD), a condition that affects millions after trauma, causing symptoms like flashbacks, avoidance, mood changes, and heightened alertness. The investigators will enroll 15 adults (ages 18-65) with PTSD. First, participants get a brain scan (fMRI) to map their unique brain connections between areas involved in fear and control-the right amygdala (fear center) and right dorsolateral prefrontal cortex (control area). Using this personalized map, the investigators will apply accelerated transcranial magnetic stimulation (TMS), a safe, non-invasive method using magnetic pulses to adjust brain activity. Treatment lasts 5 days (10 short sessions daily, totaling 90,000 pulses) targeting the identified spot to strengthen control over fear responses. The study checks if this approach is practical, safe (tracking side effects like headaches), and shows early signs of reducing PTSD symptoms (measured by questionnaires and interviews). Follow-up lasts 3 months, with repeat scans to see brain changes. This study will see if personalized, fast-paced TMS targeting the disrupted fear-control brain circuit in PTSD can be feasible and safe, and preliminarily reduce symptoms by improving brain connectivity, potentially offering a quicker alternative to standard treatments.

In recent years, the survival rate among intensive care patients has improved due to advancements in diagnosing severe infections and the use of broad-spectrum antibiotics. However, many survivors face long-term complications, known as Post-Intensive Care Syndrome (PICS), including physical, cognitive, and psychological impairments such as post-traumatic stress disorder (PTSD), anxiety, and depression. Approximately 9-27% of ICU survivors develop these symptoms, particularly those hospitalized due to sepsis. Common risk factors include traumatic hospital experiences, delirium, and extended mechanical ventilation. Despite the prevalence of these issues, most medical centers lack structured models for screening and early intervention, highlighting the need for evaluations of early intervention strategies to support at-risk patients post-discharge and improve their quality of life.

The goal of this study is to determine how non-invasive brain stimulation (delivered through the ear called vagus nerve stimulation) affects fear learning processes in people who have experienced psychological trauma. To answer these questions, we measure bodily responses (heart rate, sweat, startle) and questionnaires. The main questions it aims to answer are: Does non-invasive vagus nerve stimulation help reduce anxious arousal? Does non-invasive vagus nerve stimulation help dampen learned fear?

This open-label pilot study will evaluate the feasibility, safety, tolerability, and preliminary clinical outcomes of adding intermittent theta-burst stimulation (iTBS) to Eye Movement Desensitization and Reprocessing (EMDR) therapy in adults with post-traumatic stress disorder (PTSD), who show insufficient improvement after an initial course of EMDR. Participants will receive weekly EMDR therapy. After seven EMDR sessions, treatment response will be assessed using the Clinical Global Impression-Improvement scale (CGI-I). Participants with insufficient response will receive add-on iTBS targeted to the right dorsolateral prefrontal cortex (DLPFC) for four weeks while continuing EMDR. Feasibility outcomes include adherence, treatment completion, and dropout rates. Clinical outcomes will include clinician-rated and self-reported measures of PTSD symptoms, depressive symptoms, well-being, and adverse events.

This pilot study, conducted in partnership with juvenile detention centers, evaluates an adapted CBITS-RTM intervention delivered in a detention school setting.

The goal of this clinical trial is to learn if combining suvorexant (a sleep medication) with a shorter form of prolonged exposure therapy called PE-PC works to treat PTSD symptoms and improve sleep in Veterans and military personnel with PTSD and insomnia, with and without mild-to-moderate traumatic brain injury (TBI). The main questions it aims to answer are: Does suvorexant, when combined with PE-PC therapy, reduce PTSD symptoms more than PE-PC with a placebo (a look-alike substance that contains no drug)? Does suvorexant, when combined with PE-PC therapy, improve psychosocial and physical functioning more than PE-PC with a placebo? Researchers will compare PE-PC combined with suvorexant to PE-PC combined with a placebo to see if adding suvorexant improves PTSD symptoms, sleep, and overall functioning in Veterans. Participants will: Receive weekly PE-PC therapy sessions for 8 weeks Take suvorexant (10-20 mg) or a placebo each night during the 8-week treatment period. Complete repeated assessments of PTSD symptoms, sleep, and psychosocial and physical functioning throughout the study.

The goal of this clinical trial is to learn if a short, Zoom-based intervention, Cognitive Behavioral Therapy for Treatment-Seeking for Deaf Individuals (Deaf CBT-TS) can change beliefs about mental health treatment and increase treatment-seeking behaviors in Deaf adults with untreated mental health or alcohol use problems. It will also see if Deaf CBT-TS may reduce suicide risk and explore factors that may increase the effectiveness of Deaf CBT-TS. The main questions it aims to answer are: * Does Deaf CBT-TS increase positive beliefs about treatment and increase treatment-seeking behaviors? * Does Deaf CBT-TS increase hope and reduce mental health symptoms, suicide ideation, and alcohol use? * Is Deaf CBT-TS more effective for individuals with less cultural stress compared to those with high levels of cultural stress? * Is Deaf CBT-TS more effective for Deaf individuals in residential areas with more Deaf resources than those with less Deaf resources? Researchers will compare individuals who complete Deaf CBT-TS to those on a waitlist to see if Deaf CBT-TS works to increase positive beliefs about treatment and treatment-seeking behaviors. Participants will: * Complete a baseline assessment including demographic information, measures of hope, general mental health and functioning, alcohol use, suicide ideation, cultural stress, and beliefs about treatment. * Receive Deaf CBT-TS (2 sessions) or be placed on a waitlist with the option of receiving Deaf CBT-Ts after 4 months * Complete two follow-up assessments in 2 and 4 months.

The NEXT Study is a randomized controlled pilot examining the feasibility and acceptability of a revised perinatal PTSD protocol. This study will randomize perinatal participants with PTSD to receive NET (n=45); treatment group) and will be compared to perinatal women randomized to usual care (n=45; comparator group). The overall objective of this project is to determine the most feasible and acceptable protocol for a brief virtual perinatal PTSD intervention.

With this research investigators hope to begin to understand how rTMS can improve posttraumatic stress disorder (PTSD) symptoms. TMS improves PTSD through two interrelated mechanisms: change in brain limbic system function and change in systemic inflammatory activation. Participants who decide to join this study, will receive ten rTMS treatments. All participants will undergo a 40-minute rTMS procedure with a member of the study team 10 times over 2-4 weeks. Participants will undergo fMRI scans of the head in order to help researchers better understand potential effects of rTMS on brain activity. In addition, participants will be asked to give two breath and blood samples to look for signs of general inflammation.

The goal of the REVEAL PTSD study is to test how well the Senseye DT works as a diagnostic test for Post-traumatic Stress Disorder (PTSD) in adults 18 and older who are experiencing one or more symptoms that might be related to PTSD. The Senseye DT is software as a medical device (SaMD) and is an iPhone app that administers a series of simple tasks on the phone while recording video during the tasks through the front-facing camera. The videos are analyzed by a an Artificial Intelligence (AI) algorithm to identify physiologic signals that might be indicative of PTSD. Data collected in this study will be used to train and tune the AI algorithm, then test it for accuracy. The main questions this study aims to answer are: 1. How accurate is the Senseye DT in detecting PTSD compared to structured clinical interviews, the current clinical standard for diagnostic testing? 2. How accurately does the Senseye DT predict PTSD severity? 3. How fast is the Senseye DT to use compared to structured clinical interviews? Participants will attend a virtual screening visit via video call to determine eligibility and consent to participate. Once enrolled, participants will attend 2 or 3 additional study visits: * Visit 1: A virtual visit where standard mental health assessments will be given by clinical raters trained in mental health and administering these structured clinical interviews. These assessments include the Structured Interview Guide for the Montgomery-Asburg Depression Rating Scale (SIGMA), the Structured Interview Guide for the Hamilton Anxiety Scale (SIGH-A), and the MINI International Neurodiagnostic Interview. The Clinician-Administered PTSD Scale for DSM-5 Revised Version (CAPS-5-R) may also be conducted, if randomly selected. * Visit 2: A visit to use the Senseye DT. For participants near one of the study's physical site locations, this visit will be done in person at the site. For all others, this visit will be conducted virtually. * Visit 3: For participants not randomly selected to have the CAPS-5-R administered at Visit 1, a third and final visit will be scheduled for this assessment. This visit will be conducted virtually. The total expected participation time for enrolled participants is 6-7 hours over the course of 2-3 weeks.

Psychiatric conditions are each defined by different set of symptoms, however, they often share common characteristics such as impairments in cognitive and social functioning. These impairments can cause significant distress and disrupt daily functioning by preventing individuals from actively participating in school or work, maintaining healthy relationships with others, and engaging in everyday activities independently. The goal of this clinical trial is to examine if action-based cognitive remediation (ABCR) therapy, a type of cognitive training program, works to treat cognitive impairments in participants with psychiatric disorders. The main questions it aims to answer are: * Whether the intervention will improve the thinking skills of participants with different types of psychiatric conditions * Whether the intervention will improve social skills and work performance * Can this program be easily used in a regular hospital, and do the people who take part in it find it helpful and worth their time * Whether the improvements from the intervention last for a long time after the training is over. Researchers will compare how much the thinking skills of participants change during an 8-week waiting period (where they get no treatment) to how much they change during the 8-week training program to see if the training makes a bigger difference in helping them think and live better. Participants will : * Complete a series of questionnaires on memory, thinking skills, and mental health at the beginning of the study * Wait 8 weeks without any intervention or training * Complete the series of questionnaires again * Complete an 8-week training intervention of ABCR where they will use special computer programs to practice real-life skills and tasks like planning a meal or making an appointment * Complete the series of questionnaires and an additional structured interview to assess acceptability and feasibility of the intervention. * 3 month later, complete questionnaires for a final time.
