This study uses a computer program to listen to your speech and see if it can help detect mental health or neurodevelopmental conditions. It may help find new ways to diagnose conditions like ADHD, anxiety, depression, and others earlier.
Brookline, MassachusettsAges 13–60 - NCT05487911Enrolling by invitation
Brain stimulation (rTMS) for depression symptoms
This trial tests whether a non-surgical brain stimulation technique (rTMS) can reduce depression symptoms in adults with major depression. You would likely have several study visits that include brain scans (MRI) and treatment sessions to see if symptoms improve.
Houston, TexasAges 18–64 - NCT07217223Recruiting
Home-based brain stimulation for treatment-resistant depression
This study tests whether a gentle brain stimulation technique called tDCS can help people with depression that hasn't improved with medication. It can be done at home using a special headset and an internet connection.
San Diego, CaliforniaAges 18–85 - NCT06508710RecruitingPhase 3
Ketamine plus venlafaxine for severe depression
This trial tests whether adding ketamine to the antidepressant venlafaxine helps relieve severe depression faster than venlafaxine alone. If you are hospitalized for a serious depression and you meet safety criteria, you may be eligible.
Le Kremlin-Bicêtre, FranceAges 18–65 - NCT07105397Recruiting
AI assistant for managing depression
This study tests a conversational AI system designed to help manage depression. It may recommend treatment changes that are reviewed by a clinician, offering a new way to get support.
Fairfax, VirginiaAges 18–85 - NCT02994433RecruitingPhase 1
Testing nitrous oxide for depression brain circuit activity
This early study tests whether nitrous oxide, aimed at specific brain circuits, can change depression-related brain activity. It is mainly for adults with major depression or treatment-resistant depression, and includes brain imaging during the study.
St Louis, MissouriAges 18–65 - NCT04057378RecruitingPhase 4
Testing the best electrical settings for ECT for depression
This trial studies which electrical “pulse settings” work best during electroconvulsive therapy (ECT) for people with depression. It may help doctors personalize ECT so the treatment is safer and works as well as possible for you.
ÖrebroAges 18 years+ - NCT05239780Recruiting
Brain stimulation study for adults with depression
This study uses an invasive approach (placement of brain monitoring/stimulation) to better understand how the brain processes reward in depression. It may help researchers develop more targeted treatments in the future.
New York, New YorkAges 18–80 - NCT05573074Recruiting
Light treatment trial for brain blood flow in depression
This study tests whether shining near-infrared light through the head can change brain blood flow and reduce depression symptoms. If you have major depression, you may be offered a non-drug, device-based approach to see how well it helps.
Boston, MassachusettsAges 18–65 - NCT05786066RecruitingPhase 2
Test whether blocking AMPA changes ketamine’s suicide relief
This study looks at whether an “AMPA receptor blocker” changes how ketamine affects suicidal thoughts in people with depression that hasn’t improved with usual treatments. If you qualify, you may receive ketamine and the study medicine, while continuing your regular mental health care.
West Haven, ConnecticutAges 21–65 - NCT05961306Recruiting
Testing a stepped screening plan during pregnancy and after birth
This study checks how well a step-by-step screening approach and its tools work for identifying issues during pregnancy (weeks 20–24) or in early postpartum (6–10 weeks after delivery). It may help doctors use more accurate screening to decide who needs further care.
Ghent, Oost-VlaanderenAges 18 years+ - NCT06054321Recruiting
Depression medication study for adults 19 to 65
This study tests a new way of choosing antidepressants for people with major depression. It's designed for adults aged 19–65 who have moderate to severe depression and are either starting a new antidepressant or have been off psychiatric meds for at least a month.
GwangjuAges 19–65 - NCT06110897Recruiting
Resistance Exercise for Depression Trial
This study tests whether resistance exercise (like lifting weights) can help reduce depression symptoms. If you have major depression and are not already doing regular resistance training, you may be able to join.
Ames, IowaAges 18–65 - NCT06223880RecruitingPhase 4
AXS-05 vs Bupropion to prevent depression relapse
This study tests whether a new drug called AXS-05 can prevent depression from coming back, compared to an older drug called bupropion. If you have major depression and are at risk of relapse, this trial may help you stay well.
