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.

Study Description: This study examines relations between neurocognitive and clinical features of pediatric anxiety disorders. The study uses neuro-cognitive tasks, functional magnetic resonance imaging (fMRI), as well as magneto- and electro-encephalography (M/EEG). Patients will be studied over one year, before and after receiving either one of two standard-of-care treatments: cognitive behavioral therapy (CBT) or fluoxetine, a serotonin reuptake inhibitor (SSRI). Healthy comparisons will be studied at comparable time points. Primary Objectives: To compare healthy youth and symptomatic, medication-free pediatric patients studied prior to receipt of treatment. The study seeks to detect relations between clinical features of anxiety disorders at baseline and a wide range of neurocognitive features associated with attention, memory, and response to motivational stimuli. Secondary Objectives: 1. To document relations between baseline neurocognitive features and response to Cognitive Behavioral Therapy (CBT) or fluoxetine, as defined by the Pediatric Anxiety Rating Scale (PARS) and Clinical Global Improvement (CGI) Scale. 2. To document relations between post-treatment changes in neurocognitive features and anxiety symptoms on the PARS following treatment with Cognitive Behavioral Therapy (CBT) or fluoxetine. 3. To document relations among broad arrays of clinical, cognitive, and neural measures Primary Endpoints: Indices of percent-signal change in hypothesized brain regions, comprising amygdala, striatum, and prefrontal cortex (PFC) for each fMRI and MEG paradigm. Secondary Endpoints: 1. Treatment-response as defined by a continuous measure, the Pediatric Anxiety Rating Scale score (PARS), and a categorial measure, the Clinical Global Improvement (CGI) score. 2. Levels of symptoms and behaviors evoked by tasks that engage attention, memory, and elicit responses to motivational stimuli. ...

This study, "Biobehavioral Intervention to Reduce PTSD Symptoms After an ICD Shock," addresses a critical need in cardiology care by describing the feasibility and acceptability of a timely, highly promising, electronically-delivered intervention for patients who have recently received an ICD delivered shock. The study intervention and outcomes are designed to reduce anxiety, enhance return to activities of daily living (ADLs), and prevent the development of severe distress and post-traumatic stress disorder (PTSD), and ultimately promote quality of life. The study is a two-arm, embedded mixed methods, randomized trial (N=60, 30/group). The purpose is to determine feasibility and potential effects of a self-management intervention (SPSM) plus usual care (UC) compared to UC alone, delivered during the critical 1 month period after an ICD shock when distress is high. The intervention will be delivered over 1 month following an ICD shock; a 6-month follow-up will be used to assess the sustainability of intervention effects and determine if the incidence of PTSD is reduced. SPSM includes: 1) training in heart rate (HR) self-monitoring; and 2) individualized learning through 4 self-paced, web-based modules. The study interventions are delivered at a crucial time, closely after an ICD shock when stress is high, but PTSD has not yet developed. The specific aims are to: 1) examine the effects of the SPSM intervention plus UC vs. UC alone on the primary outcome of ICD shock anxiety at 1 and 6 months post-shock event, 2) describe the impact of SPSM plus UC compared to UC alone on the secondary outcomes of total daily physical activity, depression, PTSD symptoms, QOL, salivary cortisol levels, and self-efficacy and outcome expectations at 1 and 6 months post-shock event, and 3) assess feasibility, acceptability, and safety of the SPSM intervention, SDOH will be used to describe differential responses to the SPSM intervention. This study fills a significant gap in the care of patients with an ICD, through the systematic testing of a brief, novel and cost-effective intervention that provides the knowledge and skills to improve quality of life. Study findings will be used to design future larger RCTs to test intervention effectiveness for more diverse samples and settings.

Wide ranging cognitive deficits are major drivers of functional decline and poor outcomes in people with schizophrenia (SZ) and bipolar disorder (BD). Medications do not target pathophysiological mechanisms thought to underlie these deficits. In the search for interventions targeting underlying cognitive impairment in SZ and BD, we look comprehensively beyond just the brain and to the potential role of dysfunctional systemic metabolism. Disrupted insulin and glucose metabolism are seen in medication-naïve first-episode SZ, suggesting that SZ itself, and not just the medications used to treat it, is associated with risk of Type 2 diabetes, cardiovascular morbidity and mortality, and more generally, accelerated aging. Even young people with SZ have increased risk of metabolic disease and cognitive deficits. Sadly, their life span is shortened by 15-20 years. BD is associated with similar but less severe disruptions in glucose and insulin metabolism and life expectancy. Although the human brain is 2% of the body's volume, it consumes over 20% of its energy, and accordingly, the brain is particularly vulnerable to the dysregulation of glucose metabolism seen in SZ and BD. While glucose is considered to be the brain's default fuel, ketones provide 27% more free energy and are a major source of energy for the brain. Ketones prevent or improve various age-associated diseases, and a ketogenic diet (70% fat, 20% protein, 10% carbohydrates) has been posited as an anti-aging and dementia antidote. The premise of the work is based on recent evidence that ketogenic diets improve dynamic neural network instability, related to cognitive deficits, aging, and Type 2 diabetes (Mujica-Parodi et al., Proc Natl Acad Sci U S A. 2020;117(11):6170-7.). The rigor of the work rests on findings of (1) poor cerebral glucose homeostasis in SZ and BD, (2) neural network instability in SZ and BD, and (3) direct effects of ketosis on network instability. Unknown is whether ketogenic diets can improve network instability in people with SZ and BD.

Two hallmarks of both healthy aging and age-related disease are 1) memory and navigational deficits, particularly in orienting towards goal locations and planning how to navigate to them, and 2) increased susceptibility to stress and altered regulation of the stress response. However, there are marked individual differences in these age-related changes. The investigators' proposal will help characterize factors that contribute to this variability. Participants will be pseudorandomly assigned to stress-manipulated or control groups. The investigators will give both groups a novel immersive navigation task, validated by the PI in healthy young adults. This paradigm gives participants the opportunity to either (a) flexibly draw on spatial memory in order to plan efficient routes to goal locations, or (b) fall back on inefficient, but cognitively less-demanding, stimulus-response associations (i.e., habits). Using neuroimaging and behavioral measures, the investigators' protocol will test whether experimentally-induced stress leads individuals to bring fewer details about future locations to mind when route planning, and whether such restricted prospective thought ultimately biases participants towards relatively inflexible, habitual actions.

Mood disorders, such as depression and bipolar disorder, are difficult to treat. One reason is that there are no objective ways to measure how these disorders affect the body and respond to different treatments. In this study, researchers want to perform tests on people undergoing clinical care for mood disorders. The purpose is to understand the experience of receiving treatment for depression, bipolar disorder, and suicide risk. We also hope that this study will help us to predict which medications will improve thoughts of suicide. People 18 years or older who are receiving treatment for depression, bipolar disorder, or suicide risk may take part in this study. Participants must have also been enrolled in protocol 01-M-0254. This study will be conducted at the NIH Clinical Center in Bethesda, MD. The study typically lasts up to 12 weeks, but may last longer if a participant s treatment continues past that time. Participants will have weekly interviews and questionnaires while they are being treated for their mood disorder. Other tests are optional and include psychological testing, blood draws, sleep tests, and imaging scans. These will be done at the start and the end of research participation.

Background: Most drugs that treat mood disorders take a long time to work. Ketamine works within hours. A dose can last for a week or more. Certain receptors in the brain might help ketamine work. A drug that blocks these receptors might affect how it works. Objective: To see if the antidepressant response of ketamine is linked to AMPA receptors. Eligibility: Adults ages 18-70 with major depression disorder without psychotic features Design: Participants will be screened under protocol 01-M-0254. They will have blood tests and a physical exam. Participants will stay at the NIH Clinical Center for 5 weeks. Phase 1 lasts 4 weeks. For 2 weeks, participants will taper off their psychiatric medicine. Then they will have the following tests: - Blood draws - Psychological tests - MRI: Participants will lie in a machine that takes pictures of their brain. - MEG: Participants will lie down and do tasks. A cone lowered on their head will record brain activity. - Optional sleep tests: Electrodes on the scalp and body and belts around the body will monitor participants while they sleep. - Optional TMS: Participants will do tasks while a wire coil is held on their scalp. An electrical current will pass through the coil that affects brain activity. For phase 2, on day 0 participants will take the study drug or a placebo orally. While having a MEG, they will get ketamine infused into a vein in one arm while blood is drawn from a vein in the other arm. On day 1, participants will again take the study drug or a placebo orally. On days 3-7, they will repeat many of the phase 1 tests. Days 8 and 9 are optional and include an open label ketamine treatment and many of the phase 1 tests.
