Active clinical trials for "Mood Disorders"

Background: The COVID-19 outbreak has caused many changes to people s normal social patterns. The respiratory illness has been the major focus of public health efforts. But most experts also agree that government and public health mandates to slow the spread of the illness, such as social distancing, have a significant effect on people s mental health. Environmental stressors, such as constraints on activities, social contact, and access to resources, take a toll. Researchers want to learn how stressors related to COVID-19 affect mental health over time. Objective: To learn the relationship between stressors related to COVID-19 and self-rated measures of mental health symptoms and distress among a range of people. Eligibility: English-speaking adults ages 18 and older Design: This study will be conducted online. Participants will give their first and last name and email address. They will indicate if they have ever been in an NIH research study. They will get a username and password. Every 2 weeks for up to 6 months, participants will complete online study surveys. They will get email reminders. Some surveys will be repeated. At the end of the study, they will complete a set of end-of-study surveys. The surveys will ask about the following: Age, sex, race, and other sociodemographic data Mental and medical illness history and treatment Family medical history Mobility, self-care, and life activities Behaviors related to alcohol and substance use disorder Mental illness symptoms Psychological distress Stressors caused by the COVID-19 pandemic. Participants will get links to mental health resources, such as hotlines. They will also get guidance on steps to take to seek care or support. Study website: nimhcovidstudy.ctss.nih.gov

The coronavirus disease 2019 (COVID-19) outbreak has not only changed the lifestyles of people globally but has also resulted in other challenges, such as the requirement of self-isolation and distance learning. The COVID-19 pandemic has resulted in an inability to go out to exercise and a reduction in movement, so the demand for exercise at home has increased. To investigate the relationships between a Nintendo Ring Fit Adventure (RFA) intervention and improvements in running time, cardiac force index (CFI), centimeters per beat (CMPB), sleep quality, and mood disorders.

The goal of the study is to define and measure biological processes that contribute to the underlying pathophysiologic process of peri-partum depression to be used for identifying those at risk for developing it. This knowledge may also generate novel drug targets for peripartum depression that may be applicable to other types of depression.

Validation of [18F]-FES for imaging of estrogen receptors in the brain The primary objective of the study is to determine if [18F]-FES Positron Emission Tomography (PET) can be used to quantify the estrogen receptor expression in the human brain.

The purpose of this study is to examine the barriers and facilitators of implementing Illness Management and Recovery (IMR) in Norwegian mental health services.

In this proposal, the investigators will focus on subcortical gray and white matter structures commonly found to be abnormal in schizophrenia. Thus, the investigators will evaluate the volume and shape of the hippocampus, thalamus and basal ganglia, as well as measures of structural integrity of the corpus callosum and its various subregions.

Medications like olanzapine have been associated with the development of weight gain and diabetes in some patients. It is not known if the increased risk of developing diabetes is a direct effect on insulin or simply related to weight gain. We hope to learn in this study whether or not olanzapine directly slows down insulin secretion from the pancreas, thereby increasing the risk of developing diabetes.

This study will evaluate a possible tool for predicting future effectiveness of bright light in treating seasonal affective disorder, winter subtype, and will examine secondary effects of bright light on cardiovascular risk factors.

Positron Emission Tomography (PET) is a technique used to investigate the functional activity of the brain. The PET technique allows doctors to study the normal biochemical and metabolic processes of the central nervous system of normal individuals and patients with neurologic illnesses without physical / structural damage to the brain. When a region of the brain is active, it uses more fuel in the form of oxygen and sugar (glucose). As the brain uses more fuel it produces more waste products, carbon dioxide and water. Blood carries fuel to the brain and waste products away from the brain. As brain activity increases blood flow to and from the area of activity increases also. Knowing these facts, researchers can use radioactive chemicals (H215O) and PET scans to observe what areas of the brain are receiving more blood flow. Patients diagnosed with mood disorders and healthy volunteers will receive positron emission tomographic (PET) scans with H215O while doing simple tasks. Patients will continue to receive scans while in different mood states and while taking different medications. Patients eligible for this study will be participating in other research studies measuring other clinical and biochemical parameters (mood and anxiety ratings, medication responses, and psychological test results). Information gathered from H215O PET scans measuring blood flow to specific brain areas will be compared to the data gathered from other studies. Objectives of this study are; To determine differences in blood flow to the brain of patients with mood disorders compared to healthy volunteers. To determine differences in blood flow to the brain of patients with subtype mood disorders (such as unipolar versus bipolar) compared to healthy volunteers. 2. To determine changes in blood flow to the brain of patients with mood disorders who experience spontaneous changes in symptoms 3. To determine changes in blood flow to the brain of patients with mood disorders who receive various kinds of therapy (medication, transcranial magnetic stimulation, etc.) 4. To determine if blood flow to specific areas of the brain can be used to predict how patients will respond to certain types of therapy 5. To compare blood flow changes with various other clinical and biochemical parameters.

As the seasons change during the course of the year, many animals show major changes in their behavior and physiology. Many of these changes are triggered by changes in the length of time each night that the pineal gland produces the hormone melatonin. Melatonin is produced for a longer time in winter when nights are long, than in summer when nights are short. Some researchers believe that melatonin may play a similar role in how season effects mood of patients with seasonal affective disorder. Seasonal affective disorder (SAD) or mood disorder with seasonal pattern is a condition where the normal biorhythm is disturbed during a season, especially autumn-winter. Patients may begin experiencing or experience worsening of depressive symptoms. Patients complain of being constantly tired, craving sugary foods, overeating, and over sleeping. Researchers have collected some preliminary data showing that the duration of nighttime melatonin secretion increases in winter and decreases in summer in healthy women, but not in healthy men. However, men diagnosed with SAD have shown longer duration of melatonin secretion in the winter, similar to the duration seen in healthy women. If these early findings are confirmed it may explain why SAD is more common in women than in men. The purpose of this study is to continue researching the differences in melatonin secretion over the seasons in healthy men and women, and to determine how these findings may apply to patients with SAD.
