Group Transdiagnostic Cognitive Behavioural Therapy for Intolerance of Uncertainty Versus Applied Relaxation

Many people find uncertainty distressing, but for some, it may become overwhelming and drive persistent anxiety, worry, and avoidance. This tendency is called intolerance of uncertainty (IU), and appears across many mental health conditions, including generalised anxiety, social anxiety, depression, and obsessive-compulsive disorder, which is why researchers describe it as a transdiagnostic feature. A type of therapy called Cognitive Behavioural Therapy for Intolerance of Uncertainty (CBT-IU) has been shown to reduce anxiety in previous trials. What remains to be known is how uncertainty changes when targeted directly, and whether the same mechanism applies across diagnoses. IU has mostly been measured using questionnaires, which indicate whether people find uncertainty difficult, but not what is actually happening when they encounter it. Recent research suggests that IU is not a single trait but a set of differences in how people estimate different kinds of uncertainty. Therefore, in addition to standard questionnaires, computer-based tasks will be used to explore an "uncertainty fingerprint" for each participant, capturing different aspects of uncertainty processing in a way that self-report measures cannot. In this study, the investigators are comparing CBT-IU, adapted to work across disorders, against Applied Relaxation. Applied relaxation is a well-established therapy that teaches people to notice and release physical tension but does not focus on uncertainty. Adults with high IU and anxiety symptoms (regardless of formal diagnosis) will be randomly allocated to one of the two 12-session group therapies. The investigators will measure anxiety and IU using standard questionnaires as the primary outcomes. Additionally, cognitive tasks will be used to measure the uncertainty fingerprint before therapy, immediately after, and three months later. The aim is to test whether reductions in IU are specific to CBT-IU rather than shared with an equally credible therapy that does not target uncertainty. Going beyond self-reports, the trial will then begin to resolve which specific aspects of uncertainty processing change, so that future treatments can be more precisely targeted and better matched to each person.

Family Study of Affective and Anxiety Spectrum Disorders

This study will examine how depression, anxiety, and migraine run in families. It will help in defining the risk factors for physical, mental, and health problems-as well as define ways that those problems may be prevented and treated. A broad range of ages among family members will be included to evaluate the patterns of how these disorders are expressed throughout people's lives. Children of all ages will be included, and those ages 8 to 17 will be interviewed directly. Assessments will be collected through criteria of the Diagnostic and Statistical Manual of Mental Disorders IV as well as the spectrum, or range, of mood disorders and co-existing conditions. A member of the study team will visit the participants at home or will do an interview by telephone. Participation will take approximately 3 to 4 hours. Children will complete questionnaires given by the research team as well as questionnaires that they will do by themselves. The questions will pertain to the children's health, including physical and mental health and medical history, social relationships, problems, skills, and ways of dealing with important or stressful issues in their lives. These questionnaires will take up to 1 hour to complete. Health history gathered from adult participants will pertain to height, weight, exercise, and general function. Women will be asked about the use of oral contraceptives, estrogen, and progesterone. In addition, there will be questionnaires on personality and temperamental traits, that is, behavior and impulsiveness. Questions will also involve social intuition, family and other environmental factors, general functioning, and basic demographics such as ethnicity, race, socioeconomic status, marital status, education level, and employment history. Families enrolled in this phase of the research will be invited to participate in the next phase. There would be follow-up to evaluate the development of mood disorders, subtypes, and syndromes across the lifespan.

Investigation of the Antidepressant Effects of (2R,6R)-HNK, an Enhancer of Synaptic Glutamate Release, in Treatment-Resistant Depression

Background: Major depressive disorder (MDD) is a serious mental illness that can put people at risk of self-harm and death. Many drugs are used to treat MDD, but it can take a long time for them to be effective. Researchers want to know if a faster-acting drug, (2R,6R)-hydroxynorketamine (HNK), can better treat the symptoms of MDD. Objective: To test a study drug (HNK) in people with MDD. Eligibility: People aged 18 to 70 years with MDD. They must have had a screening assessment under protocol 01-M-0254. Design: Participants will be tapered off their current MDD drugs over 2 to 5 weeks. They will stay off of the drugs for up to 2 weeks prior to starting the study medication and procedures. They will have a physical exam with blood tests. They will have tests of their heart function, mood, and thinking. They will answer questions about their symptoms. They may choose to have imaging scans and scans of their brain activity. HNK is given through a tube attached to a needle inserted into a vein. Participants will receive infusions on this schedule: They will receive 4 infusions over 2 weeks. They will stay in the clinical center overnight after each infusion or for the duration of the study. They will receive no drugs for 2 to 3 weeks. They will have 4 more infusions over 2 weeks, with overnight stays after each or for the duration of the study. One set of 4 infusions will be the HNK. The other set of 4 infusions will be a placebo. A placebo looks just like the real drug but contains no medicine. Participants will not know when they are getting the HNK or placebo. ...

Videoconference-Based Brief Cognitive Behavioral Therapy for Patients With Mood Disorders at High Risk for Suicide

This study aims to investigate inflammatory biomarkers associated with suicide risk and to evaluate the efficacy of videoconference-based brief cognitive-behavioral therapy (V-BCBT) in patients with mood disorders at high risk for suicide. The study consists of a cross-sectional baseline comparison followed by a randomized controlled trial. Participants will include patients with depressive disorders or bipolar and related disorders who are experiencing a major depressive episode, as well as healthy controls with no lifetime history of DSM-5 psychiatric disorders. Patients with mood disorders will be classified as being at high or low risk for suicide. At baseline, all participants, including those in the high-suicide-risk, low-suicide-risk, and healthy control groups, will undergo clinical interviews, self-report questionnaires, a computer-based Death Implicit Association Test (D-IAT), and blood sampling. Clinical characteristics and inflammatory biomarker profiles will be compared across the three groups to examine the potential utility of inflammatory biomarkers for identifying individuals at high risk for suicide. Participants in the high-suicide-risk group who meet all eligibility criteria will be randomly assigned in a 1:1 ratio to V-BCBT plus treatment as usual (TAU) or TAU alone. For participants in the high-suicide-risk group, the baseline assessment will also serve as the pre-treatment assessment and will be conducted within 7 days before the start of treatment. V-BCBT consists of eight individual sessions of approximately 50-60 minutes, delivered once weekly via secure videoconferencing by trained therapists. The intervention includes crisis management, development of a suicide-focused coping plan, exploration of reasons for living, relaxation training, behavioral activation, cognitive restructuring, mindfulness, coping strategies for high-risk situations, and relapse prevention. TAU consists of routine outpatient psychiatric care and may include pharmacotherapy and supportive psychotherapy. Participants in the high-suicide-risk group will subsequently undergo a post-treatment assessment at 2 months after the baseline assessment (±7 days) and a follow-up assessment at 2 months after the post-treatment assessment (±10 days). The post-treatment and follow-up assessments will include clinical interviews, self-report questionnaires, the D-IAT, and blood sampling. Participants in the low-suicide-risk and healthy control groups will complete the baseline assessment only and will not undergo post-treatment or follow-up assessments. Post-treatment and follow-up clinical assessments of randomized participants will be conducted by evaluators blinded to treatment allocation.

Development of Magnetic Resonance Imaging Techniques for Studying Mood and Anxiety Disorders

This study is intended to help develop new MRI imaging techniques for studying mood and anxiety disorders. Researchers believe that depression and anxiety disorders may cause structural and functional changes in the brain. This study will optimize the way MRI scans are collected to look at brain structure and examine how the brain behaves while subjects perform particular tasks. Healthy volunteers and individuals with major depressive disorder may be eligible for this study. Participants undergo magnetic resonance imaging (MRI) and neuropsychological testing. : Individuals will be asked to participate in an MRI study on one of several scanners. The scanner used will measure blood flow in the brain, concentrations of certain chemicals in the brain, or magnetic properties of the brain. The scan may involve They watching a screen presenting images or doing a task in which they respond to pictures or sounds. Participants may be asked to return for additional scans. The study also involves neuropsychological tests, which assess cognitive performance. Often, people with mood disorders have subtle changes in performance on these tests that allow researchers to pinpoint where brain abnormalities occur. Before the tests can be used in patients, they must be validated by using healthy subjects. These tests are presented either orally, in written form, or on a computer.

Evaluation of Patients With Mood and Anxiety Disorders and Healthy Volunteers

The purpose of this protocol is to allow for the careful screening of patients and healthy volunteers for participation in research protocols in the Experimental Therapeutics and Pathophysiology Lab (ETPB) at the National Institute of Mental Health (NIMH) and for the collection of natural history data. In addition the protocol will allow clinicians to gain more experience in the use of a variety of polysomnographic and high-density EEG recordings. Subjects in this protocol will undergo an evaluation which may include: a psychiatric interview; a diagnostic interview; rating scales; a medical history; a physical exam; brain magnetic resonance imaging (MRI); electroencephalography (EEG); electrocardiography (EKG), magnetoencephalography (MEG); blood, saliva and urine laboratory evaluation; and a request for medical records. Subjects may also be asked to complete questionnaires about attitudes towards research and motivation for research participation. The data collected may also be linked with data from other mood and anxiety disorder protocols (e.g., brain imaging, DNA, psychophysiology tests, treatment studies, etc) for the purposes of better understanding the diagnosis, pathophysiology, and treatment response of patients with mood disorders. Parents of minors will be interviewed. Upon conclusion of the screening process, subjects will either be offered participation in a research protocol and will sign the appropriate informed consent, or will be considered not appropriate for participation in research and will be referred back into the community. The current protocol thus serves as an entry point for individuals with mood or anxiety disorders or healthy volunteers to enter NIMH IRB approved ETPB protocols.

7T Amygdala and Citalopram Study

The goal of this study is to investigate how a common antidepressant citalopram (which increases the levels of the chemical messenger serotonin), affects how a key area of the brain involved in depression (the amygdala) responds to emotional information. Healthy participants will undergo medical and psychiatric health screening, after which they will be assigned to receive either a single dose of citalopram (20mg) or placebo, and undergo brain scanning (7T fMRI) whilst viewing emotional faces. Since the scan uses high field strength, the investigators will be able to see effects of citalopram on different subfields within the amygdala which will help to understand how citalopram might be working.

Intergenerational Study of War-Affected Youth

War-related violence is a leading driver of mental disorders and illness affecting children in low- and middle-income countries (LMICs). Parents exposed early in life to war-related violence and loss are at risk for mental health problems and may pass risks to their offspring. The study posits that war-related trauma alters the stress-response circuitry in ways that endure into adulthood and affect the next generation. This will be the first investigation in a 20-year longitudinal study to examine mechanisms that link parental war-related trauma exposure and subsequent mental health problems to risk for mental disorders in offspring. This study will extend the first intergenerational study of war in Sub-Saharan Africa (R01HD073349) to focus on children (aged 7-24) born to war-affected parents. Assessments of behavioral and biological indicators of the Research Domain Criteria (RDoC)-linked constructs of self-regulation and stress reactivity will be collected, including autonomic nervous system reactivity, inflammation, and telomere length as well as sophisticated observations of parent-child interactions and synchrony. These measures will be utilized to identify potentially modifiable risk and protective processes both to inform the development of screening tools to identify families at risk for poor child mental health and to be deployed as active ingredients of interventions to reduce transmission of mental health problems to children of war-affected parents. This follow-up study involves the following activities: 1. Pilot to assess measure performance and field test study protocols. 1. Translation and adaptation of newly selected measures 2. Pilot study of new child and adult measures with 36 caregivers and 60 children in a district of Sierra Leone unlinked to participants to test the feasibility and validity of new tools. 2. Fifth wave of data collection from war-affected youth who are now parents and their children aged 7-24. 1. Household tracking and re-enrollment of 145 households that were formerly enrolled in the Longitudinal Study of War-Affected Youth (LSWAY; T1: 2002, T2: 2004, T3: 2008, T4: 2016). 2. Quantitative (full sample) and qualitative (subsample) data collection with 145 households who were enrolled in T4 LSWAY, including war-affected youth who are now parents, their intimate partners, and their children aged 7-24. Through these activities, the investigators will test three overarching hypotheses: 1. Childhood war-related trauma exposure will be associated with mental difficulties (anxiety, depression, post-traumatic stress, disruptions of emotion regulation). 2. Poor mental health in war-affected parents will be associated with emotional and behavioral disruptions in biological offspring. 3. Risk and protective factors across the social ecology may serve as intervention targets to mitigate the effects of parental war-related trauma on behavioral disruptions and stress physiology, both within and across generations.

Neuro-computational Study of Thymic Fluctuations in Mood Disorders

Depression and bipolar disorder are frequent, debilitating conditions. Both are thought to be primarily caused by an impaired regulation of mood, which is why they are sometimes referred to as "mood disorders". However, the biological basis of mood remains poorly understood, which is a major limitation for the development of new treatments. Recent work that combines neuroscience with mathematical models are promising to better understand mood and to link it to its biological basis, but they don't have any medical application yet. Can these models describe mood in a way that is relevant to mood disorders, and help doctors and psychologists predict subsequent clinical evolution? With the objective of extending this framework to real-life fluctuations and to assess its clinical relevance, this study will combine a neuroimaging session with a smartphone-based, longitudinal follow-up. Three groups of 96 subjects each will be recruited: depressive disorder, bipolar disorder and healthy controls. They will have their mood fluctuations assessed first in the lab (in the neuroimaging experiment), then in their daily lives (by providing a few ratings and choices every day on the smartphone app). This study will allow to better understand the differences in how patients' mood reacts to daily events, as compared to people who don't suffer from depression or bipolar disorder. The combination of the two steps will allow to assess whether a short neuroimaging evaluation can be useful to predict subsequent clinical evolution during the following months. The investigators wanted to add two optional ancillary studies. The first uses a mobile application for implicit, passive, and longitudinal mood assessments through emotion tracking. Indeed, it seems relevant to add this type of evaluation alongside explicit assessments to more accurately detect mood fluctuations. The second study uses a mobile application that allows voice recordings. The analysis of these vocal parameters will help to characterize a specific linguistic and vocal profile within the three groups, as well as to identify specific symptoms of conditions such as depression and bipolar disorder. These ancillary studies will be offered to both patients and the control group.

Studying the Health of Asians to Advance Knowledge, Treatments, and Interventions for Depression

SHAKTI (from the Sanskrit word for "power") is a 5-year natural history, longitudinal, prospective study of a cohort of 6,000 participants that will help uncover the socio-demographic, lifestyle, clinical, psychological, and neurobiological factors that contribute to antidepressant treatment response (remission, recurrence, relapse and individual outcomes in depressive disorders) and resilience. As this is an exploratory study, we will assess a comprehensive panel of carefully selected participant specific parameters - socio-demographic (age, sex, gender, race, ethnicity, economic); life habits (physical activity, substance use); clinical (medical history, anxious depression, early life trauma), biological (biomarkers in blood, saliva, urine, stool), behavioral (cognitive, emotional), neurophysiological (EEG), and neuroimaging (magnetic resonance imaging; MRI) with the goal of developing the most robust predictive models of depression treatment response and of outcomes.

Mindful Yoga for Postpartum Depression

This is a parallel-group randomized controlled trial. A total of 198 postpartum women with depressive symptoms (EPDS scores≥8 at baseline) will be recruited and randomized into two groups: 10-week mindful yoga intervention and 10-week psychoeducation program. Clinical assessment of depression, self-report questionnaires and salivary cortisol tests will be performed at baseline, after 10-week intervention, and at 6-month and 12-month follow-ups. The investigators expected that the mindful yoga intervention will reduce depression after 10 weeks compared to psychoeducation. The mindful yoga intervention will further reduce anxiety, stress, improve quality of life and sleep, and steepen diurnal cortisol slopes. These effects will be maintained for at least six months.

Resilience in Adolescent Development

RAD is a 10-year natural history, longitudinal, prospective assessment study of a cohort of 2,500 participants (ages 10-24 years) that will help uncover the socio-demographic, lifestyle, clinical, psychological, and neurobiological factors that contribute to resilience among children, adolescents, and young adults at-risk for mood and anxiety disorders. As this is an exploratory study, we will assess a comprehensive panel of carefully selected participant specific parameters, including socio-demographic, life habits, clinical, biological, behavioral, neurophysiological, and neuroimaging. The study is designed to observe and collect factors associated with resilience in a non-invasive fashion; no interventions or treatments will be conducted during the project. Assessments will be conducted up to 4 times per year for up to 10 years, as well as a baseline visit. Study visits will be conducted in person whenever feasible but may be completed by phone/mail/computer, if an in-person visit is not possible.

Youth Suicide Risk Factors, Reduction of Suicide Risk Factor in Youth People

The YOU-SURF project is at the forefront of youth suicide prevention, with the goal of integrating multimodal clinical and neurobiological data to comprehensively identify risk factors and the most effective intervention strategies. Suicide is one of the leading causes of death among young people, with particularly alarming incidence rates during adolescence and early adulthood. Suicidal risk is a complex phenomenon, determined by a multiplicity of clinical, environmental, and biological factors. Emerging evidence suggests that information derived from neuroimaging, genetics, and the microbiome may also play a significant role. However, studies conducted to date have not yet adopted a truly multimodal approach that jointly integrates these dimensions in the identification of risk factors for suicide in youth. The YOU-SURF project aims to fill this critical gap. YOU-SURF will also pioneer the use of deep transcranial magnetic stimulation (dTMS), an innovative neuromodulation technique, whose effectiveness in reducing suicidal risk in young people will be assessed within a longitudinal design. Although some preliminary evidence suggests a potential benefit of neuromodulation treatments in this population, the specific effects of dTMS on suicidal risk in youth remain largely unexplored. Furthermore, there is a significant lack of knowledge regarding predictors of response to dTMS in young individuals at risk for self-harming behaviors. The specific objectives of the project are as follows: 1. To identify youth suicide risk factors through the integration of clinical, environmental, neuroimaging, genetic, and microbiome data; 2. To longitudinally evaluate the effectiveness of dTMS in the treatment of young people at risk of suicide; 3. To develop a predictive model based on machine learning techniques, grounded in multimodal data, to estimate the individual response to dTMS in this population. The results of the project will provide a solid scientific basis for the development of personalized prevention and treatment interventions, improving clinical effectiveness and resource allocation in youth mental health services.

Individualized Functional Connectivity Targeting in aiTBS for Depression

The goal of this clinical trial is to estimate the importance of neuroimaging in accelerated intermittent theta burst stimulation (aiTBS) for depression. Participants will receive aiTBS treatment, but they will not know if their treatment spot was found with neuroimaging or head measurements.

AI-Enabled Smartwatch for Medication Adherence in Outpatient Psychiatry

Medication nonadherence remains difficult to measure objectively in psychiatric care. This completed, single-center exploratory randomized trial evaluated whether four weeks of AI-enabled smartwatch medication monitoring improved clinician-rated medication adherence compared with waitlist usual care in psychiatric outpatients aged 12 years or older, predominantly adolescents and young adults with mood disorders.

Suicide Specific Rumination in Veterans

Few treatments target core features of suicidal thoughts and behaviors in Veterans. Real-time functional magnetic resonance imaging neurofeedback can provide information regarding brain activation associated with suicide-specific rumination, defined as a "repetitive mental fixation on one's suicidal thoughts and intentions." The goal of this feasibility study is for Veterans to learn strategies for modulating activity within brain regions that have been demonstrated to contribute to the maintenance of rumination, as they receive neurofeedback feedback signals from the brain.

Digital Mental Health for Asian Americans

Aim 1: Assess clinicians' receptiveness and potential use of Anise's online platform digital tools for managing sociocultural stressors and revise the tools for implementation. We will recruit 8 new clinicians (intervention group) who will receive training and provide feedback on the digital tools. Aim 2: Evaluate the initial efficacy of the online platform digital tools for managing the impact of sociocultural stressors with 64 Asian American clients. The intervention group clinicians (receiving training and using the digital tools) and newly recruited 8 clinicians (not receiving training and not using the digital tools) for the control group will work with 4 clients each. The clinical outcome data of the clients will be analyzed to examine differences in the client prognosis between the control and intervention group. A successful outcome of this project will be digital materials that effectively address the impact of sociocultural stressors for Asian Americans on Anise Health's digital health platform.

MyFILM: A Pilot Study for Social-Emotional Learning in Clinical Youth

The objective of this pilot study is to evaluate the feasibility and acceptability of MyFILM as a weekly group intervention for children aged 9-12 in a clinical setting. We will also gather preliminary data to explore changes in clinical metrics following participation in MyFILM in preparation for a full-scale clinical trial. Primary Objective (Feasibility): To determine whether a substantial proportion of participants complete the MyFILM intervention. Primary Objective (Acceptability): To determine whether the MyFILM intervention is acceptable to 9-12-year-old participants in a clinical setting. Secondary Objective (Clinical Effectiveness): To determine whether participation in MyFILM show preliminary evidence of improvement in social-emotional skills, coping ability, and reduction in anxiety and depression symptoms. Participants will: Participate in 9 sessions of a structured group-based program.

Search for Novel Transcranial Magnetic Stimulation (TMS) Targets for Mental Illness

Participants will receive Transcranial Magnetic Stimulation (TMS) at a random location in the left prefrontal cortex, excluding sites that are potentially unsafe. Extensive behavioral testing will be conducted to determine which behaviors are modulated by stimulating which circuits.

An Innovative Master Platform for Clinical Trials in Mood Disorders

Mood disorders such as depression and bipolar disorder affect over 350 million people around the world. While several effective treatments exist, it is often difficult to match the right treatment to an individual person. Repeated efforts to find the right treatment contribute to poor functioning, low quality of life, and prolongs the time it takes to get well. Most areas of medicine are able to use 'biomarkers' or clinical tests, blood tests, or imaging to help diagnose and treat illness. The search for biomarkers in mood disorders is advancing, but one roadblock to progress is the lack of large, standardized studies of mood disorders that are needed to accurately identify biomarkers. The aim of the ENABLE platform is to provide the Canadian neuroscience community a standardized way of collecting biomarker data from individuals with a range of mood disorders symptoms. In addition, this 'master clinical trial platform' framework will provide a pool of participants who can be recruited into biomarker-based clinical trials.

Testing a Transdiagnostic TMS Treatment Target

The goal of this clinical trial is to test a new brain stimulation treatment target for individuals with depression plus at least one additional psychiatric disorder. The main question is to understand the safety profile of a non-invasive form of brain stimulation called accelerated intermittent theta burst stimulation when it is targeting the posterior parietal cortex. Additional questions focus on whether this stimulation improves symptoms of depression and other psychiatric disorders as well as whether this stimulation changes brain function.

Psilocybin-Assisted Psychotherapy for Treatment-Resistant Depression: Comparing One Versus Two Doses of Psilocybin

The purpose of this study is to see if one or two doses of psilocybin is more effective in relieving depressive symptoms in patients with treatment-resistant depression (TRD). Researchers also want to know if a second dose of psilocybin is safe and well-tolerated. This study will see if psilocybin is effective, safe, and well-tolerated by tracking changes in depressive symptoms, suicidality, and side effects. This study will also see if a second dose of psilocybin has an effect on quality of life, functioning, cognition (thinking, reasoning, remembering), and how long depressive symptoms improve (or worsen) after psilocybin is administered.

Phase II: Engagement and Clinical Impact of the Teleo Virtual Therapy Platform in Clinical Settings

This Phase II trial will examine engagement in telehealth for children undergoing psychotherapy. Specifically, the trial will examine patient engagement in Teleo, a virtual therapy platform specifically designed for psychotherapy with youth, as compared to standard video conferencing.

Whole-Body Hyperthermia for Mood and Anxiety Disorders

This study aims to examine the scientific mechanisms of whole-body hyperthermia (WBH), a novel, rapidly acting, single session antidepressant and anxiolytic therapy. It also aims to determine its feasibility and acceptability in women with postpartum depression (PPD). The study will enroll four cohorts of participants: healthy postpartum controls; postpartum women with PPD; healthy adult controls; and adults with major depressive disorder or anxiety disorders in a longitudinal protocol.
