The gut microbiome has been shown to impact various facets of human health, including mental health. Studies have shown that populations with more agrarian lifestyles tend to have fewer chronic diseases and mental health issues than industrialized populations. A possible factor in these differences is the loss of co-evolved gut microbial taxa that has occurred with Westernization. This hypothesis, termed "Old Friends Hypothesis" suggests that the loss of certain gut microbes leads to immune dysregulation and increased chronic inflammation that contributes to development of cancers, cardiometabolic diseases and even neuroinflammation that can lead to negative behavioral and mental health outcomes. Other studies have shown that increasing the intake of plant foods may help increase diversity of the microbes in the gut and that this increased diversity could lead to better health outcomes in humans. The investigators propose to evaluate daily consumption of a drink consisting of a high diversity of plants (30 plant species) for four weeks on the diversity of the gut microbiome, biological signatures of inflammation, quality of life, sleep quality, and PTSD symptoms among persons with a diagnosis of PTSD. The investigators hypothesize that four weeks of daily consumption of this high plant diversity beverage (30 plant species) will increase gut microbiome ɑ-diversity, reduce markers of systemic inflammation, and improve PTSD symptom severity relative to daily consumption of a beverage containing only three plant species.
Pregnant women with a primary diagnosis of posttraumatic stress disorder (PTSD) (PTSD Checklist for DSM-5 (PCL-5) score \> 33) will be randomized to receive conventional cognitive processing therapy (CPT) (60-min session once/week for 12 weeks) or massed CPT (mCPT) (an intensive schedule of 12 60-min sessions over 5 days, approximately 2-3 sessions per day) via telemedicine, for treatment of PTSD. The research aims will be three-fold: (1) Evaluate the relative efficacy and tolerability of CPT vs. mCPT for treatment of perinatal PTSD and depression; (2) Determine the effect of CPT upon maternal-infant attachment and interaction; (3) Collect pilot data of obstetric and neonatal outcomes among those receiving the two CPT delivery schedules.
This is a randomized, sham controlled study of the Electroencephalogram (EEG) based Transcranial Magnetic Stimulation (eTMS) treatment for Post-Traumatic Stress Disorder (PTSD). The recruitment goal is 110 participants who are United States Military veterans or first responders (e.g., firefighters, police, paramedics, etc.). The Study includes an EEG recording in order to determine the optimal treatment parameters for the eTMS system, followed by 15 in-office visits that take place over 21-28 total days. Two eTMS treatment sessions are administered during each office visit.
Prism is a software as a medical device (SaMD) to be prescribed by clinicians as an adjunct to the standard of care treatment of patients with PTSD. The Prism software device runs on a laptop using an EEG signal input (g).Nautilos PRO (K171669). The primary objective of the study is to extend the use of the FDA cleared Prism for PTSD (K222101) to an adolescent population and to confirm the safety of fifteen (15±3) EEG-NF training sessions using the Prism software in reducing PTSD-related symptoms in adolescents. The study aims to demonstrate the safety profile of Prism, having no device-related serious adverse events (SAEs), consistent with findings in the adult population, throughout the course of Prism treatment in an adolescent population.
This study is being done to see if Prolonged Exposure (PE), a well-researched, very effective individual (one-to-one) behavioral therapy designed to help people to directly deal with traumatic events they have suffered in the past, can be combined with intranasal esketamine (ketamine) for the treatment of posttraumatic stress disorder (PTSD) to enhance treatment benefits. Ketamine nasal spray is a drug approved by the U.S. Food \& Drug Administration (FDA) for treatment resistant depression. Combined with PE, intranasal ketamine may help to augment PE and further reduce participants' PTSD symptoms.
The goal of this study is to test whether anesthesia-induced dreaming can help alleviate symptoms of PTSD in an (1) open-label trial (Phase I) and (2) double-blind, randomized controlled trial (Phase II) in a non-surgical setting. The investigators predict that inducing and sustaining a dream state prior to emergence from anesthesia will result in reduced symptoms of PTSD. Participants will undergo EEG-guided propofol anesthesia during which they will be either (1) receiving deep sedation leading to loss of responsiveness, designed to elicit dream reports upon emergence (Dream Protocol), and/or (2) light sedation without loss of responsiveness, designed to elicit non-dream experiential reports while responsive (e.g., simple imagery, sounds, thoughts, bodily sensations, hypnagogic-like experiences) (Non-Dream Protocol). The investigators will then investigate whether the deep-sedation Dream Condition is associated with a larger reduction in PTSD symptoms than the light-sedation Non-Dream Condition.
The goal of this clinical trial is to characterize the role of sleep, emotion processing, and daily affect in post-traumatic stress disorder (PTSD) and whether improving sleep quality using slow wave activity enhancement will impact next-day affect in youth. Participants will attend 4 study visits: * A clinical and trauma assessment visit * A testing day that may include cognitive testing, surveys, and an MRI. * An overnight sleep study following one week of at-home sleep recordings with the device in the sham condition * An overnight sleep study following one week of at-home sleep recordings with the device in the sleep enhancement condition
The goal of this clinical trial is to test how exercise affects learning and memory processes relevant to the treatment of PTSD. Participants will complete a baseline intake followed by two experimental sessions. During the first experimental session, participants will undergo an MRI session of imaginal exposure to traumatic memory cues followed by 30-minutes of moderate intensity exercise or low intensity exercise. Participants will complete a second session of imaginal exposure with MRI 24 hours later.
In partnership with the Veterans Affairs (VA) Palo Alto Health Care System and Stanford University, this study aims to evaluate clinical outcomes, assess implementation feasibility, and health economics of MDMA-assisted Cognitive Processing Therapy (MDMA-aCPT) in the treatment of posttraumatic stress disorder (PTSD). Through a randomized comparison of MDMA-aCPT versus Cognitive Processing Therapy (CPT), a VA gold standard treatment for PTSD, the proposed study will set the stage for understanding the potential use and application of MDMA-aCPT for PTSD within the VA system.
This randomized, double-blind, single-site phase II 2-arm study will investigate the safety and preliminary efficacy of MDMA-assisted therapy compared with low dose d-amphetamine-assisted therapy on the severity of PTSD symptoms in participants aged 18 years and older with PTSD of at least moderate severity.
