Recruiting studies
- NCT07572526Recruiting
Brain Stimulation to Improve Sleep and Mood in Depression
This study tests a non-invasive brain stimulation technique called tDCS (transcranial direct current stimulation) to see if improving sleep can help reduce depression symptoms. You'll do short stimulation sessions at home and track your sleep and mood.
New York, New YorkAges 18–65 - NCT06732089Recruiting
Digital help for stubborn depression
This trial tests a digital program (smartphone app or website) to help people with tough-to-treat depression. If you are already receiving advanced treatments like rTMS, ketamine, or ECT at St. Michael's Hospital, you may be able to join and see if this extra digital support improves your mood.

Sertraline Plus Probiotic for Teen Depression
This study tests whether combining sertraline (an antidepressant) with a specific probiotic called Lactobacillus crispatus can safely and effectively treat depression in teenagers. The probiotic may help by improving gut health, which researchers believe could support mental health.
Longgang, Chongqing MunicipalityAges 12–18 - NCT07533773Recruiting
Brain Activity Changes After Depression Treatment
This study measures how brain activity in specific regions changes after you receive electroconvulsive therapy (ECT) or magnetic seizure therapy (MST) for severe depression. Researchers use a non-invasive headband to monitor blood flow in your brain before and after treatment to better understand how these therapies work.
Hefei, AnhuiAges 12–65 - NCT07523048RecruitingPhase 2
Dextromethorphan-Bupropion for Moderate-to-Severe Depression
This study tests a combination medication (dextromethorphan plus bupropion) to see how it affects brain activity in people with moderate-to-severe depression. Researchers use brain imaging (fMRI) to understand how the drug works and whether it may help relieve depression symptoms.
Toronto, OntarioAges 18–65 - NCT07508215Recruiting
Bright light therapy for memory problems in depression
This study tests whether daily bright light therapy can improve thinking and memory in people with major depression. You would continue your regular antidepressant and add 30-60 minutes of light box use each morning.
Beijing, Beijing MunicipalityAges 18–60 - NCT07474363Recruiting
Depression differences between men and women
This study looks at how depression affects men and women differently, including symptoms, strength to cope (resilience), and feelings of stigma. It aims to understand these differences to improve treatment.
Eskişehir, EskişehirAges 18–65 - NCT07479758Recruiting
Brain scans and vision tests for severe mental illness
This study uses advanced MRI scans and visual perception tests to learn more about severe mental disorders like depression, schizophrenia, and bipolar disorder. It aims to improve diagnosis and treatment outcomes.
Hangzhou, ZhejiangAges 18–45 - NCT07462013Recruiting
Lifestyle changes to prevent memory loss with depression
This study tests if healthy lifestyle changes can protect memory and thinking skills in people with depression who have no or mild memory problems.
Taichung, TaichungAges 50–80 - NCT07439744Recruiting
Omega-3 for Depression and Obesity
This study tests whether omega-3 fatty acids can improve depression in people with obesity. It looks at how these healthy fats might reduce inflammation and help mood.
Taichung, TaichungAges 18–54 - NCT07422844Recruiting
Brain network changes during TMS for depression
This study looks at how transcranial magnetic stimulation (TMS) affects brain networks in people being treated for depression. If you are already scheduled to receive TMS for depression, you may be able to join and help researchers understand how the treatment works.
Frankfurt am Main, HesseAges 18–70 - NCT07402356Recruiting
Virtual reality eye test for thinking problems
This study uses virtual reality and eye-tracking (pupillometry) to measure thinking and memory problems in people with Alzheimer's, mild cognitive impairment, or depression. It aims to find better ways to detect and track cognitive changes using a simple, non-invasive procedure.
München, BavariaAges 18–80 - NCT07388004Recruiting
Comparing two group therapies for depression
This trial compares two types of group therapy for major depression: one that focuses on changing your expectations about the future, and another that helps you reconnect with rewarding activities. The goal is to see which approach works better for reducing depression symptoms.
Marburg, HesseAges 18–80 - NCT07369180Enrolling by invitation
TMS for treatment-resistant depression in adults
This study tests a new type of transcranial magnetic stimulation (TMS) for adults whose depression hasn't gotten better with medication. It compares the real treatment to a sham (inactive) version to see how well it works.
Campbell, CaliforniaAges 22–85 - NCT07345858Enrolling by invitation
Saliva test for psychedelic depression treatment
This trial tests whether a simple saliva test can measure oxytocin levels during a psychedelic treatment for hard-to-treat depression. The goal is to find a biological marker that helps predict how well the therapy works.
GenevaAges 18 years+ - NCT07328373Recruiting
Depression Relapse Predictors Study
This trial looks at brain and genetic markers to understand why depression returns. It is for people with major depression who are not currently taking medication.
IstanbulAges 18–65 - NCT07324070Recruiting
Adding TMS to ECT for hard-to-treat depression
This study tests whether adding TMS to ECT can better treat depression that hasn't improved with other treatments. It is for adults with moderate to severe major depression who haven't had these treatments recently.
Prague, CzechAges 18 years+ - NCT07314190Enrolling by invitation
Blood tests for brain diseases and mental health conditions
This study looks at blood tests to help diagnose and track brain diseases (like Alzheimer's) or mental health conditions. It compares patients to healthy volunteers to find better ways to detect and monitor these illnesses.
BarcelonaAges 18 years+ - NCT07300969RecruitingPhase 2
Testing DT-101 for adults with depression
This trial tests a new medicine called DT-101 to see if it helps people with depression. It is for adults who have had more than one depressive episode in their life.
Bentonville, ArkansasAges 18–75 - NCT07284667RecruitingPhase 2
A new medicine for depression that hasn't improved with other treatments
This trial tests a new medicine called ACP-211 in adults with major depression who have not gotten enough relief from at least two previous antidepressants. The goal is to see if it can help when other treatments have not worked well.
Birmingham, AlabamaAges 18–65 - NCT07269964Recruiting
At-home brain stimulation for depression maintenance
This trial tests if a gentle, at-home brain stimulation treatment (tDCS) can help prevent depression from returning after successful initial treatment with esketamine, rTMS, or ECT. It is for people who are stable but want to stay well.
München, BavariaAges 18 years+ - NCT07247344Recruiting

Nanjing, JiangsuAges 10–20 - NCT07230990Recruiting
Brain Stimulation Study for Depression
This study uses a special type of brain stimulation (rTMS, which uses magnetic pulses) to treat depression. It focuses on part of the brain called the orbitofrontal cortex and aims to understand how stimulating it helps improve mood.
