This study tests a new drug called mitizodone phosphate in 600 adults with major depression. The goal is to see if it reduces depression symptoms better than a placebo over 8 weeks. The trial has two phases: first to find the best dose, then to confirm how well it works and if it…

This study tests a new treatment called Prism for people with major depression who have lost interest or pleasure in activities (anhedonia). Prism is a software device that uses neurofeedback to train the brain's reward system. About 170 participants will receive either real Pris…

This study is testing a virtual reality (VR) program called bWell to see if it is a practical and enjoyable way to help people with major depression who have trouble with thinking and memory. Forty adults aged 19-55 will either use the bWell cognitive training or experience VR sc…

This study tests whether using a bright light device at home for 40 minutes each morning can help teens aged 13-17 with major depression. Participants are split into three groups: high-intensity light, medium-intensity light, or a dim red light placebo. The goal is to see if ligh…

This study is for people with spinal cord injury who also have depression. It tests a new method to dose a brain stimulation treatment called rTMS, which is already approved for depression but usually requires a thumb movement to set the dose. Since many with spinal cord injury h…

This study tests whether using a person's own brain scan to guide a non-invasive treatment called iTBS works better than the standard one-size-fits-all approach. About 210 adults with major depression will receive 6 weeks of iTBS, with the treatment spot chosen either by standard…

This study is testing a new social skills training program for Veterans with serious mental illness (like schizophrenia, bipolar disorder, or PTSD) who are looking for work. The program teaches skills to better understand social cues and handle workplace relationships. Researcher…

This study explores whether increasing non-exercise activity—like walking to the store or doing chores—can improve energy levels in people with major depression. Researchers will use smartphone prompts and activity trackers to encourage small movements throughout the day. The goa…

This pilot study tests whether giving brain stimulation three times a day (accelerated) works better than the standard once-daily schedule for teenagers aged 16-19 with treatment-resistant depression. Ten participants will receive fMRI-guided theta burst stimulation, a non-invasi…

This study tests an experimental drug to see if it can fix brain patterns linked to avoiding rewards in people with major depression or anxiety. About 112 unmedicated adults will have brain scans and do decision-making tasks. The goal is to understand how the drug works, not to c…

This study looks at how ketamine works in the brain to relieve depression. Researchers are giving people with hard-to-treat depression either a placebo or a drug called perampanel before a dose of ketamine. They will use brain scans to see if blocking certain brain receptors chan…

This study looks at how nitrous oxide (laughing gas) changes brain connections in people with hard-to-treat depression compared to healthy volunteers. About 50 participants will get either the gas or a placebo and have their brains scanned with MRI. The goal is to understand how …

This study explores whether a single dose of L-dopa, a drug used for Parkinson's, can improve motivation and motor function in people with major depression who have signs of low-grade inflammation. Researchers will compare L-dopa to a placebo in 165 participants (patients and hea…

This study aims to find brain-based markers that can predict how well people with major depression respond to repetitive transcranial magnetic stimulation (rTMS) therapy. Researchers will use MRI and EEG to track brain changes in 50 adults with moderate to severe depression who h…

This study is looking for ways to predict which patients with severe depression will respond well to electroconvulsive therapy (ECT). Researchers will use brain scans, blood tests, and spinal fluid samples from 30 patients before and after ECT. The goal is to find biological mark…
