Computer Game, Qualitative, and MEG/EEG Assessment of Serotonergic Psychedelics
Yale University OCD Major Depressive Disorder (MDD) Alcohol Use Disorder (AUD) Healthy Volunteer Migraine
The goal of this observational study is to learn how the brain's information processing changes during and following administration of serotonergic psychedelics (psilocybin, N,N-Dimethyltryptamine/DMT, Lystergic Acid Diethylamide/LSD, etc.) for people with and without mental illness receiving serot1 expand

The goal of this observational study is to learn how the brain's information processing changes during and following administration of serotonergic psychedelics (psilocybin, N,N-Dimethyltryptamine/DMT, Lystergic Acid Diethylamide/LSD, etc.) for people with and without mental illness receiving serotonergic psychedelics through any clinical trial at Yale University. The main questions it aims to answer are: 1. Do serotonergic psychedelics cause the brain to rely on new information more than previously learned information while under the influence? What about 1 day, 5-14 days, and 4-6 weeks after use? 2. Do serotonergic psychedelics cause long-lasting side-effects in how people perceive (see, hear, feel, etc.) the world and how easily people change their beliefs? 3. How does the brain's electrical activity change after using serotonergic psychedelics? How does the balance between excitation and inhibition change while under their effect? 4. Can changes in how the brain uses information predict who will benefit from a psychedelic and who will have side effects from psychedelics? Researchers will compare with people given placebos to see what changes in brain processing are unique to serotonergic psychedelics. Participants will have the opportunity to do some combination of the following: 1. Online computer assessments consisting of games and questionnaires that probe how participants think. 2. Magnetoencephalography (MEG) or electroencephalography (EEG) with eyes closed and with repeated clicks, images, or sensations delivered. 3. A magnetic resonance imaging (MRI) scan. 4. Semi-structured qualitative interviews about their experience after taking a serotonergic psychedelic recorded via Zoom.

Chronic pain (CP) is a major health problem for military Veterans, and CP is often associated with comorbid mental health problems, including posttraumatic stress disorder (PTSD) and depression. CP with psychological comorbidity is associated with increased healthcare costs, medication use, risk of suicide and rates of disability and reduced quality of life. Current empirically supported treatments do not always lead to substantial improvements (up to 50% of patients drop out or are do not respond to treatment). This project was designed to evaluate the efficacy of a novel intervention for addressing these challenges. Compassion meditation (CM), a meditative practice that focuses on the wish to remove suffering, is a contemplative practice that has promise for the amelioration of physical and mental health problems as well as promoting positive affect and improving quality of life. This study will evaluate the efficacy of Cognitively-Based Compassion Training for Chronic Pain with Psychological Comorbidity (CBCT-CP+) compared to Health Education while Living with Pain (H.E.L.P.) control condition, in a sample of among Veterans with CP conditions and psychological comorbidity.

This research study is designed to test if electrical stimulation of the surface of the brain in the frontal region will help treat depressive symptoms. Participants receive intermittent electrical stimulation to the brain, which involves surgically placing electric leads in between the tough fibrous membrane covering the surface of the brain and the surface of the brain itself. This type of stimulation is referred to as bilateral subdural prefrontal cortical stimulation (PCS) because it will specifically target the outer layer of the brain at the midline, right behind the forehead. It uses a pacemaker-like device, the Proclaim Elite SCS System (non-rechargeable) or the Eterna SCS System (rechargeable), both by Abbott Laboratories for stimulation. Although the U.S. Food and Drug Administration (FDA) has approved the Proclaim Elite SCS system for brain stimulation for patients with chronic pain and muscular diseases, such as Parkinson's, its use is still investigational, and the surgery is still experimental for patients who have depression.

This study is intended to help develop new MRI imaging techniques for studying mood and anxiety disorders. Researchers believe that depression and anxiety disorders may cause structural and functional changes in the brain. This study will optimize the way MRI scans are collected to look at brain structure and examine how the brain behaves while subjects perform particular tasks. Healthy volunteers and individuals with major depressive disorder may be eligible for this study. Participants undergo magnetic resonance imaging (MRI) and neuropsychological testing. : Individuals will be asked to participate in an MRI study on one of several scanners. The scanner used will measure blood flow in the brain, concentrations of certain chemicals in the brain, or magnetic properties of the brain. The scan may involve They watching a screen presenting images or doing a task in which they respond to pictures or sounds. Participants may be asked to return for additional scans. The study also involves neuropsychological tests, which assess cognitive performance. Often, people with mood disorders have subtle changes in performance on these tests that allow researchers to pinpoint where brain abnormalities occur. Before the tests can be used in patients, they must be validated by using healthy subjects. These tests are presented either orally, in written form, or on a computer....

Bipolar I disorder (BP-I) is a common, chronic, and disabling mental illness with significant morbidity and mortality defined by episodes of mania and depression (or symptoms of both at once, known as mixed features). This prospective, observational study will examine effectiveness, functioning and quality of life outcomes in adult patients with BP-I experiencing a major depressive episode (with or without mixed features) requiring treatment and initiating treatment with cariprazine. It will examine outcomes of cariprazine treatment in a real-world setting in patients with BP-I commonly seen in clinical practices. Cariprazine (Vraylar) is a medication indicated in the United States and Canada to treat adult patients experiencing manic, mixed or depressive episodes associated with BP-I. This study plans to enroll approximately 170 adult patients with BP-I from the United States and Canada. Cariprazine should be prescribed by the physician under the usual and customary practice of physician prescription. The decision to initiate treatment with cariprazine should be made prior to, and independently from, the patient's decision to participate in the study. Participants will receive cariprazine as prescribed by their physician. Observational data will be collected during visits which should align to routine standard of care for a duration of up to 24 weeks.

Although most people recover from acute pain (such as pain caused by injury, surgery, repetitive motion, or unknown causes), many people do not fully recover and will experience chronic pain. Untreated posttraumatic stress disorder (PTSD) appears to be a key risk factor for the transition from acute pain to chronic pain. However, few published studies have addressed the issue of preventing the transition from acute to chronic pain via PTSD reduction. This project will aim to test whether trauma-related PTSD symptoms can be reduced using either Stellate Ganglion Block (SGB) treatment or Cognitive Processing Therapy (CPT), and whether reducing PTSD symptoms can prevent the transition from non-injury based acute pain to chronic pain.
