Before medications are approved by the U.S. Food and Drug Administration (FDA) or before certain therapy methods are widely accepted as effective, they are tested on people who volunteer to participate in a clinical trial.

Organizations across the country are looking for people like you to take part in their research studies. The list of studies below have been selected from ClinicalTrials.gov based on their inclusion of one or more of the following terms: anxiety disorders, depression, OCD, PTSD, and bipolar disorder.

The Anxiety and Depression Association of America (ADAA) is supportive of research that is conducted through clinical trials. Participating in research can potentially help change the mental health outcomes for you and others who suffer anxiety, depression, and related disorders.

The goal of this neuroimaging study is to investigate how emotional states fluctuate in people with bipolar disorder (BD) compared to healthy controls, and to understand the neural mechanisms driving mood instability. The main questions it aims to answer are: - Can emotional states be decoded from fMRI brain activity using machine learning? - Do individuals with BD show more unstable emotional state trajectories (e.g., high metastability, low fractal scaling) than healthy controls? - Does amplifying positive emotions stabilize brain and emotional dynamics in BD? Researchers will compare individuals with bipolar disorder (BD-I or BD-II, currently depressed or mixed state) to healthy controls without psychiatric history to see whether the BD group shows greater fluctuations in emotional brain activity and whether positive emotion regulation strategies normalize this instability. Participants will: - Complete self-report questionnaires on mood, emotion regulation, anxiety, and daily functioning. - Recall and provide short descriptions of personal positive and negative memories to be used in the MRI task. - Undergo fMRI scanning, including: - Resting-state scans - A Think and Regulate Affective States Task (TReAT) where they recall autobiographical memories, rate emotions, and practice amplifying positive mood. - Structural and diffusion MRI for brain mapping. - Receive physiological monitoring (heart rate, respiration) during scanning. - Complete post-scan surveys on emotional state and task experience. This research will help clarify how the brain supports or disrupts emotional regulation in bipolar disorder and may inform the development of personalized, neurobiologically informed treatments for mood instability.

This study teaches participants who are having colorectal surgery how to use mindfulness to feel calmer and manage pain better. Participants will be randomized (like a flip of a coin) into one of two groups: Mindfulness Intervention or Standard Treatment. Those in the Mindfulness group will have a 30-minute Zoom session before surgery to learn simple mindfulness exercises like deep breathing, using senses, and staying focused on the present. On the day after surgery, participants will watch a short video review of the mindfulness exercises. Regardless of the group assigned, participants may be asked to complete questionnaires, and some participants will be asked to complete a semi-structured interview via Zoom, about 2 weeks to 1 month after surgery. Additionally, access to the mindfulness curriculum will be provided to those not randomized to that group. Investigators will collect information such as age, surgery details, pain levels, and pain medication usage. Participants will also fill out surveys before and after surgery to assess physical and mental well-being. All personal information will be kept safe, and interviews or Zoom sessions will be deleted after notes are taken without names attached. Participants will be in this study for about 4 weeks.

The goal of this clinical trial is to test how specific components of diet affect brain function and behavior for individuals with bipolar. The main question it aims to answer is how glucose and ketones each affect the brain's response to risk and reward. Participants will be asked to provide blood (to assess baseline measures of how the body uses energy), and then to receive two MRI scan sessions, on separate days. During each MRI scan session, participants will play three games, from which they can win money, before and after drinking glucose (on one day) or ketones (on the other day). Investigators will compare individuals with and without bipolar to test whether the two groups differ in how their brains use energy, and to test how the brain's use of energy affects behavior.

Veterans with bipolar disorders (BD) experience recurrent and seemingly unpredictable periods of severe impairments in psychosocial functioning, such as participation in social roles and activities. Many effective treatments for BD emphasize early detection of bipolar episodes, in order to make necessary treatment adjustments and prevent psychosocial impairments associated with acute mood episodes. Unfortunately, acute mood episodes in BD are also associated with a decrease in a patient's insight into their own symptoms, which can prevent one's ability to self-report first signs of symptoms and functional declines. Moreover, routine care visits for BD are typically too infrequent to capture and effectively monitor day-to-day changes in a patient's mood and functioning. Objective, low-effort, and continuous methods of tracking symptoms and social participation of Veterans with BD in real-time and in-situ are needed to provide early (i.e., days in advance) warning signs of acute bipolar episodes and functional declines, which in turn would enable well-timed interventions to prevent poor psychosocial outcomes. mHealth refers to the use of mobile and wireless devices as part of patient care and offers many potential opportunities for early detection of and intervention for acute mood states in this population. However, these mHealth approaches have not been investigated in Veterans with BD. In a Small Projects in Rehabilitation Research (SPiRE)-funded pilot study, the investigator team established high feasibility and acceptability of one such innovative passive mHealth approach using a smartphone program, or an app, in a small sample of Veterans with BD to track their smartphone's GPS/location. The pilot study used a priori location context ratings of visited places (e.g., a priori ratings on types of activities usually engaged in at a frequently visited location) to derive unobtrusive measures of social participation (e.g., time spent at work-related locations). The goal of this Merit Review proposal is to establish reliable and valid machine-learning algorithms using the same types of mHealth data to prospectively (days in advance) detect declines in social participation and prospective onset of mania and depression in Veterans with BD. This proposal has three aims: Aim 1. To establish a machine learning algorithm using GPS/location data for predicting prospective declines in social participation in Veterans with BD. Aim 2. To establish machine learning algorithms using GPS/location data for predicting prospective acute BD clinical states. The investigators will explore whether adding more burdensome daily self-report and voice diaries' speech analysis features improves the models' precision using statistical indices of prediction precision or accuracy. Aim 3. To explore clinical implementation of the mHealth-based algorithms in treatment of BD. Focus groups of VA providers and administrators will assess feasibility of algorithms' implementation in clinical care.
