Multi-centre, parallel group, blinded, 1:1 randomized controlled trial to determine the effect of nitrous oxide on reducing symptoms of depression in patients with treatment resistant depression.

The purpose of this study is to use a non-invasive imaging technique called positron emission tomography/magnetic resonance imaging (PET/MRI) to investigate the effects of exercise on brain activity and arterial (blood vessel) inflammation in people with PTSD symptoms and evidence of or elevated risk for artery disease.

The RESPOND trial explores the link between early life adversity and later life depressive symptoms. The investigators have designed a new psychological therapy tailored to address the symptoms that can be caused by difficult experiences in early life. These symptoms include low mood, emotional dysregulation, and distressing thoughts and beliefs related to difficult or traumatic experiences. The investigators would like to see if this new therapy helps people feel better. The investigators are also studying the biological changes that can occur as a result of early life adversity, and how this therapy may influence those changes. To do this, The investigators ask questions about participants' physical and mental health and take blood samples.

The goal of this study is to improve depression treatment by establishing reliable prefrontal excitability markers through Targeting with Automated Real-time Guidance for Enhancing TEPs (TARGET).

This randomized clinical trial will enroll 100 Veteran-family/friend dyads to test the efficacy of CALM in treating anger in TBI and PTSD. The investigators hypothesize that compared to an active control group, Veterans randomized to the CALM group will demonstrate: * Significantly larger decreases in anger dysregulation, impulsivity, and executive dysfunction. * Significantly larger improvements in social and adaptive functioning including less aggression. * Significantly larger reduction in PTSD symptoms and suicidal ideation. The study targets Veterans who experience difficulties with anger and impulsivity due to TBI and PTSD. These issues are common, with up to 38% of Veterans with TBI also having PTSD. These conditions often make it challenging for Veterans to control their emotions and interact successfully in social and work settings. Our research will test the CALM (Cognitive Applications for Life Management) mobile app, which helps Veterans manage their goals, remember important tasks, and improve their attention. Initial tests of CALM have shown it can reduce levels of anger and related issues in Veterans. The investigators will conduct a study with 100 pairings of Veterans and a family member or friend. These pairs will be randomly assigned to one of two groups: one using the CALM mobile platform and the other receiving brain health education. Both groups will use their assigned intervention for three months and will receive support through videoconference calls at the beginning, middle, and end of the program.

The purpose of the study is to evaluate a trauma informed digital multicomponent intervention design to improve health and safety outcomes for women with lifetime exposures to violence and co-occurring PTSD and/or depression symptoms

This study will evaluate the efficacy and safety of SPN-821 in adults with major depressive disorder

The purpose of this multi-site randomized controlled trial is to evaluate the efficacy and risks of psilocybin for the treatment of depression in U.S. military Veterans with and without (±) concurrent posttraumatic stress disorder.

The rationale for the use of inhalational cannabis to potentially treat PTSD symptoms is based on the many reports of cannabis attenuating PTSD symptom expression among individuals with PTSD, including veterans. Study MJP2 is intended to build off MJP-1 through use of a larger sample size, a parallel study design, and subjective bias mitigation methods to re-examine the use of inhaled high THC-containing cannabis versus placebo for management of PTSD symptoms in a U.S. Veteran sample. Together these studies are intended to provide valuable insights on the already widespread use of cannabis in individuals with PTSD, for which there is currently a lack of controlled evidence available reflective of this real-world use.

This study investigates the effects of intentionally sequencing aerobic exercise immediately prior to cognitive behavioral therapy (CBT) to determine its effects on mechanisms of CBT (i.e., working alliance, behavioral activation). To assess the utility of this treatment augmentation, investigators will conduct a randomized controlled trial involving 100 adults with Major Depressive Disorder who will watch a nature documentary while either resting quietly ( 'CalmCBT') or exercising at a moderate intensity ('ActiveCBT') immediately prior to 8 weekly sessions of CBT.

The goal of this clinical trial is to determine whether which types of integrative care, meaning a combination of psychotherapy and mind-body interventions, lead to the most changes in functioning among Veterans with posttraumatic stress disorder (PTSD). The main aims are: 1. To evaluate the impact of integrative care approaches on functional outcomes among Veterans with PTSD. 2. To examine factors relevant to the implementation of integrated treatments for PTSD from the perspective of patients, providers and administrators in the VA Healthcare System. Participants will: 1. Complete assessments at the beginning of the study and 12- and 24-weeks later. 2. Engage in 12 weeks of integrated care, with the type being randomly assigned.

Low-income individuals have limited access to evidence-based interventions for mental health. Peer recovery specialists, individuals in recovery from mental health and/or substance use problems, have the potential to increase access to evidence-based interventions for individuals from low-resource communities, particularly when trained and supervised in models that are acceptable and feasible in these communities. This study will examine the effectiveness and implementation potential of a peer-delivered evidence-based intervention (Behavioral Activation) among individuals receiving services from a community-based treatment setting providing integrated physical and behavioral healthcare.
