Smartphone-based Ambulatory Assessment of Early Warning Signs

Bipolar disorders are severe chronic disorders, marked by recurrent episodes of depression and (hypo)mania. The disorder usually emerges in early adulthood and tends to have a highly unpredictable course. Prevention of these episodes is essential, as they are associated with marked impairment in social and occupational functioning. The investigators propose to conduct a randomized, multi-center, observer-blind, parallel group controlled trial with an 78 week (18 month) intervention phase to test the hypothesis that continuous ambulatory real-time monitoring of early warning signs for new depressive or (hypo)manic episodes by smartphone based, innovative technology (e.g. GPS, acceleration sensor), including individual threshold- based early intervention for these early warning signs, will prolong time to a new mood episode and reduce hospitalizations (intervention group). In the control group ambulatory monitoring of early warning signs for emerging depressive or (hypo)manic episodes will occur in an identical manner, but the results will not be transmitted to the treating psychiatrist. All patients in this trial, irrespective of their group assignment, will receive guideline-based, state-of-the-art maintenance treatment.

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.

Enhancing Veteran-Clinical Collaboration in VA PRRCs

Over 60% of Veterans with serious mental illness have a service-connected disability that impairs their ability to work, go to school, and/or have successful personal lives. Although traditional treatments tend to focus on symptom remission, Veterans prioritize a range of treatment goals, including personal empowerment and gaining personally meaningful skills. Increasing Veteran-clinician collaboration can help effectively align care with each Veteran's goals and support an empowering therapeutic experience. This project will evaluate the effectiveness of a group-based intervention intended to increase Veterans' comfort, confidence, knowledge, and skills to collaborate with their treatment teams. Findings from this study will contribute important knowledge about this intervention's effectiveness and how to enhance its effectiveness, especially for Veterans from minoritized groups. If the decision-making intervention is effective, it would help Veterans with serious mental illness, and might also help Veterans with other chronic health conditions, like PTSD and chronic pain.

COMpassion for Psychiatric Disorders And Self-Stigma

People with mental disorders face frequent stigmatizing attitudes and behaviors from others . In response to this, they tend to isolate themselves, with the risk of impeding care and the process of recovery and integration into society . Stigmatization can also be assimilated by patients themselves - i.e. self-stigma. Self-stigma is involved in diminished coping skills that lead to social avoidance and difficulties in adhering to care . Reducing self-stigma and its emotional corollary, shame, is thus crucial to attenuate the disability associated with mental illness. Shame is inherent to self-stigma and leads to difficulties in adhering to care as well as greater severity of clinical presentations . Compassion Focused Therapy (CFT) is a third wave cognitive behavioral therapy that targets shame reduction and hostile self-to-self relationship and allows for symptom improvement while increasing self-compassion, a major resilience factor . Although shame is a prominent part of the concept of self-stigma, the efficacy of CFT has never been evaluated in individuals with high levels of self-stigma. In this study, the investigators will evaluate the efficacy and acceptability of a group based CFT program on decreasing self-stigma, compared to treatment as usual (TAU) and a psychoeducation program whose efficacy has been assessed in a previous trial.

NIMH Rhythms and Blues Study: A Prospective Natural History Study of Motor Activity, Mood States, and Bipolar Disorder

Background: Mood disorders, such as bipolar disorder, can have serious effects on a person s life. People with bipolar disorder are more likely to have heart disease and abuse substances. In this natural history study, researchers would like to learn more about the connection between exercise and mental health in people with and without mood disorders. Objective: To better understand relationships among physical activity, sleep, and mental health. Eligibility: People aged 8 to 60 years with a history of a mood disorder. Healthy spouses and relatives with no mood disorders are also needed. Design: Participants will be in the study up to 2 years. For up to 20 days in a row, at 4 times during the study, participants will: Complete an electronic diary on their smartphone. Participants will answer questions about their mood, health, sleep, and daily activities. Wear an activity monitor, like a wristwatch, that records how much they move. Wear a light sensor, as a necklace, to record the amount of light in their environment. Some participants will do additional tests. Twice during the study, for 3 days in a row, they will: Wear monitors to record their temperature, heart rate, and sleep. Provide saliva samples. Complete cognitive tasks on their smartphone. Participants will visit the NIH clinic 2 times. They will have a physical exam, with blood and urine tests. They will wear a heart monitor. They will ride a stationary bike for 30 minutes. They may have an imaging scan. Some participants will stay overnight. They will go to sleep wearing a cap to measure their brain activity.

Low Amplitude Pulse Seizure Therapy Versus Standard Ultra-Brief Right Unilateral Electroconvulsive Therapy

This protocol proposes an initial randomized clinical trial that includes all patients with suicidal ideation (SI) at baseline, and with SI as the primary outcome measure to examine whether Right Unilateral Low-Amplitude Pulse - Seizure Therapy (RUL LAP-ST) treatment has more magnitude and rate of remission of SI as conventional pulse amplitude Right Unilateral Electroconvulsive Therapy (RUL ECT) (based on our prior secondary analysis). Our central hypothesis is that RUL LAP-ST has significantly less cognitive/memory side effects (no memory side effects were noted in our prior studies for 500mA and 600mA) and thus is more favorable in terms of side effects compared to RUL conventional pulse amplitude ECT, while maintaining better anti-suicidal effect.

Transcranial Electric Stimulation Therapy (TEST) for Treatment Resistant Depression (TRD)

Background: People with TRD are often helped by electroconvulsive therapy (ECT). But ECT can affect memory and thinking. Researchers want to study a treatment called TEST that uses less electricity. Objective: To study the safety and feasibility of TEST and assess its antidepressant effects. Eligibility: Adults aged 25-64 with major depression that has not been relieved by current treatments. Design: Participants will be admitted to the NIH Clinical Center for 5 18 weeks over 2 3 treatment phases. Their medications may be adjusted. Participants will be interviewed about their depression, side effects, and other treatments they are receiving. They will complete questionnaires. They will give blood and urine samples. Their brain waves and heart rhythm will be recorded. They will take tests of memory, attention, mental functioning, and thinking. Participants will have magnetic resonance imaging (MRI) scans of the head and brain. They will lie on a table that slides in and out of the scanner. Pictures of brain chemicals will also be taken. They may complete tasks during the MRI. Participants will receive TEST and/or sham treatments. They may receive optional ECT. An intravenous catheter will be placed in an arm vein to receive general anesthesia. Two electrodes will be placed on the front of their head. An electric current will be passed from the ECT machine through the electrodes. For sham treatments, they will not receive the electric current. Their breathing, heart rate, brain function, blood pressure, and body movements will be measured. Participants will have 7 follow-up visits over 6 months. Visits can be done via telehealth. Participation will last for up to 42 weeks.

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.
