Filter by:Despite efforts to prevent suicide, US rates are climbing, and suicide is the second leading cause of death among youth. Digital tools, especially personal smartphones, are promising avenues to address these issues and can be used to provide a unique understanding of risk factors, including psychological distress, anhedonia and behavioral withdrawal, and sleep disturbance among high-risk individuals. This project aims to enhance the effectiveness of the delivery of preventative health care to youth at risk for suicide by developing a comprehensive digital platform that allows practitioners to integrate mobile sensing data and HIPAA-compliant client communication tools into their management of these young people.
The main aim of this research is to explore the effects that ketamine has on the functional connectivity of the brain in participants with treatment resistant depression (TRD). This study will investigate the relationship between these changes and response to treatment as measured by clinical scales, as well as examining drug induced changes in reward and emotion based brain activity, structural connectivity, cerebral blood flow, cognition, metabolism and blood markers of brain plasticity.
The goal of this interventional double-blind study is to demonstrate the safety and efficacy of PRISM neurofeedback training within an MDD Anhedonia sample. The main questions it aims to answer are: 1. what clinical profile / symptoms-based biomarkers scores can be used by clinics to administer PRISM therapy in conjunction with standard care of therapy? 2. What are the initial guidelines for integrating PRISM neurofeedback training for MDD therapy with MDD Anhedonia? Participants will be randomly assigned to one of two arms, Active, or Sham. During the study, participants will perform the following: - Complete clinical assessments using questionnaires, an MRI scan, and tasks that probe reward responsivity, learning, and motivation. - Perform 15 (+/-3) neurofeedback training sessions (performed twice a week on nonconsecutive days for about 2 months). - Complete the same clinical assessments, post-NF training MRI scan, and tasks same as in the screening/baseline stage. Researchers will compare the sham and treatment arm to evaluate if the neurofeedback effect reduced MDD symptoms in MDD patients with Anhedonia.
The purpose of this 10-week, double-blind, placebo-controlled study is to determine whether inflammation impacts reward and motor neural circuitry to contribute to depressive symptoms like anhedonia and psychomotor slowing in people with Human Immunodeficiency Virus (HIV) and depression. Sixty male and female patients with HIV who have depression, anhedonia and high inflammation and are stable on effective treatment for their HIV will be randomized to receive either the anti-inflammatory drug baricitinib or a placebo for 10 weeks. Participants will complete lab tests, medical and psychiatric assessments, neurocognitive testing, functional MRI (fMRI) scans, and optional spinal taps as part of the study. The total length of participation is about 5 months.
The purpose of this study is to assess the socio-demographic, disease-related and treatment-related characteristics, and the standard of care (SOC) treatment patterns of participants with major depressive disorder (MDD) with anhedonia with inadequate response to their current antidepressant treatments and treated according to the standard of care treatment.
The purpose of the study is to assess the long-term efficacy and safety of add-on pramipexole for treatment of patients with anhedonic depression.
This study aims to investigate the effects of mental imagery practice on depression, behavioral activation, psychological well-being and other processes involved in depression such as anhedonia. We use a multiple baseline design in addition to a pre-post and follow-up standardized assessment design.
This research will use biobehavioral approaches to generate understanding about the linkages between sleep duration and timing, stressful life events, and depressive symptoms in adolescents, with a long-term aim of developing effective preventative interventions.
The purpose of this research study is to better understand anhedonia in Major Depressive Disorder by investigating the reward-related neural and inflammatory correlates.
This is a clinical trial study that aims to evaluate the specificity of the relationship between reduced sensitivity to social reward and social anhedonia at both behavioral and neural levels. Individuals who recently experienced their first-episode psychosis will be recruited. Participants will be randomized 1:1 to motivational interviewing or a time- and format-matched control probe. At pre- and post-probe, participants will perform two social reward learning tasks in the scanner. With this design feature, we will examine the relationship between sensitivity to social reward and reduced subjective experience of social pleasure at both the behavioral and neural levels.
