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....

Emotional Eating, Sleep Quality, Mental State and Metabolic Syndrome

In predominantly medication-naïve schizophrenic patients, those exhibiting partial metabolic disorders have significantly worse sleep quality and sleep onset time; poor sleep predicted metabolic dysregulation even after controlling for confounding factors. Mental health, sleep, and eating behavior interact in ways that strongly influence the risk of obesity and MetS. Emotional eating (eating in response to emotions rather than hunger) is central to this network and appears to be closely associated with psychiatric illnesses, particularly depression, anxiety, and sleep disorders. There is a continuing need to elucidate the frequency, level, and relationship of emotional eating with other factors in individuals with SMI. Therefore, this study aims to elucidate this complex relationship, thereby shedding light on new ways to reduce metabolic risks in psychiatric patients.

Venous Tourniquet vs. Arterial Tourniquet for Seizure Monitoring in ECT

This prospective, open-label clinical trial aims to compare a novel "Venous Tourniquet with Regional Low-Dose Sugammadex" method against the gold standard "Arterial Tourniquet" (Isolated Forearm Technique - IFT) for monitoring motor seizure activity during Electroconvulsive Therapy (ECT). Using a within-subject (intra-individual) design, each of the 40 enrolled patients will receive an arterial tourniquet on one arm and a venous tourniquet on the other arm simultaneously. The study will evaluate clinical efficacy in observing motor seizures, comparing the duration and visibility between the two limbs of the same patient, as well as assessing overall patient comfort and hemodynamics.

BezafibrateTreatment for Bipolar Depression: A Proof of Concept Study

We propose to test the hypothesis that bezafibrate, a pan-PPAR agonist, may be effective and safe for bipolar depression with the following specific aims: Aim #1. Proof-of-Concept Safety and Tolerability Aim: To assess the safety and tolerability of bezafibrate added to anti-manic medication for bipolar depression, especially with regard to worsening manic symptoms and suicidal ideation. We will conduct a phase IIa, 8-week, open pilot trial of bezafibrate added to FDA-approved anti-manic medication in 30 participants with bipolar depression. We will monitor changes in manic symptoms (Young Mania Rating Scale), suicidal ideation, cognitive functioning specifically in attention and verbal memory, and treatment emergent adverse events (SAFTEE). We will also monitor changes in the Framingham Cardiovascular Risk Score. Aim #2. Preliminary Assessment of Efficacy: To assess the antidepressant efficacy of bezafibrate added to anti-manic medication for acute bipolar I major depressive episodes. Hypothesis: The bezafibrate group will have a statistically significant decrease in the Montgomery Asberg Rating Scale (MADRS) Scores over 8 weeks. The results of this proof-of concept phase IIa study will help us to plan a placebo-controlled randomized trial. In summary, we propose an 8-week, proof-of-concept open pilot trial of an adjunctive pan-PPAR agonist, bezafibrate, for 30 patients with an acute bipolar I major depressive episode. The study may have a profound impact on the development of a novel treatment consistent with the mitochondrial dysregulation hypothesis of bipolar disorder and, to the best of our knowledge, will be the first proof-of-concept trial to assess a pan-PPAR agonist for bipolar disorder.

Intermittent Theta Burst Stimulation (iTBS) for Emotion Regulation in Bipolar Disorder

The objective of this study protocol is to test whether intermittent theta-burst transcranial magnetic stimulation (iTBS-TMS) to the inferior parietal lobule (IPL) can strengthen functional connectivity with a key region in emotion regulation (ER) neurocircuitry (anterior insula, AI) and improve performance on ER-related tasks in patients with bipolar disorder. Individual IPL sites for stimulation will be identified through baseline, pre-TMS functional magnetic resonance imaging (fMRI) scans. Patient-specific IPL subregions showing positive functional connectivity with the anterior insula and falling within the patient-specific frontoparietal control network will be used as individualized target sites for TMS stimulation. Patients will be randomized to receive 24 sessions of active versus sham iTBS to patient-specific IPL targets (6 sessions/day, 4 days, 43,200 pulses total). Post-iTBS resting-state and task-based fMRI scans will be acquired 3 days after the final day of iTBS administration (Day 4) following identical procedures as baseline. Effects of iTBS-TMS on ER will be evaluated by comparing pre-TMS versus post-TMS functional connectivity and behavior during performance on ER tasks.

The Effect of Comorbid Alcohol/Substance Use

Study Design This study was designed as a comparative, cross-sectional case-control study examining the effect of comorbid alcohol and substance use disorder (ASUD) on clinical course and social inclusion among individuals with severe mental illness followed at a Community Mental Health Center (CMHC). The study did not involve any interventions. Aim The aim of this study is to examine the effect of comorbid alcohol and substance use on clinical course parameters-such as number of hospitalizations and medication dosages-and on social inclusion indicators-such as employment, social participation, and social adjustment-among individuals with severe mental illness followed at the CMHC, in comparison with a matched control group without substance use. Research Questions What are the rates of comorbid alcohol and substance use among patients with severe mental illness followed at the CMHC? What are the current addiction symptoms, number of hospitalizations, and employment rates among individuals with severe mental illness and comorbid ASUD? What is the level of continuity of CMHC engagement and social participation among individuals with severe mental illness and comorbid ASUD, and what factors influence it? How does the level of social inclusion among individuals with severe mental illness and comorbid ASUD compare with that of individuals without ASUD? Hypotheses H1: The average annual number of hospitalizations among individuals with a dual diagnosis (severe mental illness + ASUD) followed at the CMHC is significantly higher than among those without substance use. H2: Among individuals with a dual diagnosis, the daily medication doses (e.g., chlorpromazine equivalents) required to control psychotic or manic symptoms are higher than in the control group. H3: Social inclusion is lower among patients with substance use compared with the control group. H4: Employment rates among individuals with a dual diagnosis are significantly lower than among those with severe mental illness alone. H5: Substance use negatively affects patients' social participation, including involvement in activities and friendships. H6: Attendance rates at CMHC workshops and rehabilitation programs are lower among individuals with substance use compared with the control group.

Investigation of Factors Associated With Preserved Cognitive Function in Bipolar Disorder

Bipolar disorder (BD) ïs the fourth leading cause of disability worldwide among young people. Differences in demographic and clinical characteristics between patients do not influence educational achievement and receipt of disability pension, indicating that there are other factors such as neurocognitive function that are of importance for maintaining occupational and social function. Research has shown that at the group level, cognitive deficits are present in euthymic BD patients, while approximately 30%-50% of BD patients is not different from healthy controls when it comes to cognitive function. There is however little knowledge of risk and resilience factors for cognitive impairment in BD. Factors likely to contribute to cognitive and functional outcomes in BD, such as sleep, obesity, biological rhythms, comorbid medical and psychiatric conditions are also understudied. While it has been customary to focus research on factors related to the negative illness trajectories, the overarching aim of the current project is to explore factors associated with favourable outcomes. This shift in research focus is essential to elucidate factors related to more preserved function since this represents a clear gap in knowledge today.

EPI-MINN: Targeting Cognition and Motivation - National

The purpose of this study is to perform a practice-based research project designed to assess whether cognition and motivated behavior in early psychosis can be addressed as key treatment goals within real-world settings by using a 12-week mobile intervention program. We will recruit participants who are receiving care for early psychosis from clinics across the United States. We will compare outcomes from participants who receive treatment at coordinated specialty care (CSC) early psychosis clinics to those that receive standard community care. A qualifying CSC program will provide comprehensive clinical services such as psychotherapy, medication management, psychoeducation, and work or education support. This study will be conducted remotely, and participants can participate at home with their own electronic devices. The aim of this study is to investigate a well-defined 12-week mobile intervention program specifically designed to target cognitive functioning and motivated behavior for individuals with early psychosis. Participants will complete a screening interview which will include diagnosis and symptom ratings, neurocognitive assessment, and self-reports of symptoms, behavior, and functioning. Then participants will be randomized to receive the 12-week mobile intervention, or an active control of treatment as usual. The investigators will test for differences in the clinical trajectories after training, and at two follow up appointments at 6 and 12 months post-training.

Evaluating the Impact of Ketogenic Therapy on Symptom Severity and Metabolic Side Effect Profile Among Individuals Living With Bipolar Disorder in A Rural Southern Catchment Area

It is the purpose of this pilot study to evaluate a high-fat/low-carbohydrate "ketogenic" diet-based intervention as an adjunctive strategy for impacting symptoms of bipolar disorder. The study is designed to evaluate this impact in the rural southern catchment area around Montgomery, Alabama. While existing access and cost barriers can prevent effective treatment of bipolar disorder in the rural south, using food as medicine represents a possible alternative/adjunctive to traditional high-cost/low-access medications. Specifically, this study will evaluate the impact of combining a ketogenic diet with existing treatment options, under the conditions of the rural catchment area, to determine the impact and efficacy of this intervention at patient and systems levels. If effective, the interventions examined in this pilot study may increase the efficacy, availability and access to care experienced by individuals living with bipolarity in the rural Deep South.

Premorbid Personality Profile of Patients With Cognitive and Behavioral Disorders

Damages in frontal area present in neurodegenerative disease (frontotemporal degeneration, frontal variant of Alzheimer disease) and in psychiatric disease (bipolar disorder) can affect behavior and cognition including social cognition. Symptoms vary both quantitatively and qualitatively from disease to another and from person to person. It cannot be completely excluded that in some cases, factors of susceptibility such as premorbid personality traits lead to frontal fragility. The study will assess the relationship between premorbid profile using NEO-PI 3 inventory and cognitive and behavioral/psychobehavioral manifestations in patients with behavioral variant of frontotemporal disorder (bvFTD), phenocopy frontotemporal dementia (phFTD), frontal variant of Alzheimer disease, bipolar disorder characterized with frontal damages.

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.

Improving Adherence in Adolescents and Young Adults With Bipolar Disorder

Although poor medication adherence occurs in more than 65% of adolescent and young adults (AYA) with bipolar disorder (BD) and is associated with poor recovery, high rates of relapse, and a 5.2 fold increased suicide risk, there have been no interventions that specifically target adherence in AYA with BD. This proposal will modify and test a customized adherence enhancement (CAE) intervention developed by the investigative team and found to be effective in BD adults in a high-risk, high-need group: AYAs with BD who are poorly adherent with prescribed BD medications. The project addresses the critical need for evidence-based interventions to improve adherence in AYAs with BD and has the potential to change outcome trajectories in high-risk young people with BD as they transition to adulthood.
