NAC to help prevent chemo brain fog in ovarian cancer
This Phase 1/2 study tests whether taking NAC (a supplement medicine) can help prevent or reduce memory and thinking problems after platinum chemotherapy. It targets people with advanced ovarian, fallopian tube, or primary peritoneal cancer who are starting at least six cycles of platinum-based treatment.
Orange, CaliforniaAges 18 years+ - NCT04581902Recruiting
Study blood and brain markers in moderate to severe depression
This study looks at changes in depression “markers” to understand what treatments help and why. You’ll have non-invasive brain stimulation and scans before and after treatment, over about 8 weeks.
San Francisco, CaliforniaAges 18–70 - NCT04526600Recruiting
Study of fidgeting and attention in ADHD
This study looks at how fidgeting relates to attention and emotional control in people with ADHD. It may help researchers understand ADHD better and improve how symptoms are measured or supported.
Sacramento, CaliforniaAges 18–30 - NCT04556890Recruiting
Brain stimulation for treatment-resistant depression and chronic pain
This study tests a non-invasive brain stimulation treatment, called transcranial magnetic stimulation (TMS), to see if it can help people who have both major depression that hasn't improved with medication and chronic pain from fibromyalgia or chronic fatigue syndrome. It aims to reduce both depression and pain symptoms.
Los Angeles, CaliforniaAges 18–75 - NCT04569448RecruitingPhase 3
Brexpiprazole for bipolar depression that won’t improve
This Phase 3 study tests whether brexpiprazole can help treat bipolar depression that has not responded to previous treatments. It compares the study medicine to a placebo (inactive pill) for people with bipolar I or II depression.
Hamilton, OntarioAges 18–75 - NCT04576182Recruiting
Therapy for depression using emotion-focused sessions
This study tests a structured talk-therapy program (supportive-expressive and emotion-focused therapy) for people with major depression. It may help by teaching new ways to understand and work with emotions as part of treatment.
HaifaAges 18–65 - NCT04532190Recruiting
Testing options beyond standard ADHD treatment
This study looks for alternatives to standard treatment for attention-deficit/hyperactivity disorder (ADHD). It may help by testing a different approach for people who meet specific age, language, and health requirements.
Calgary, AlbertaAges 9–15 - NCT04575337Recruiting
Biomarker study to help detect Alzheimer’s early
This study looks for brain/biological “signals” (biomarkers) that may identify Alzheimer’s disease earlier, including stages before clear symptoms. You may be followed for about 5 years, with repeated memory and thinking testing to see how these signs relate to future diagnosis.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04504721Enrolling by invitation
Light therapy for fibromyalgia using blue-enriched white light
This study tests whether a specific type of light (blue-enriched white light) can reduce symptoms of fibromyalgia. It may help people feel better by changing how the body responds to light.
TaipeiAges 20–64 - NCT04493996Recruiting
Cognitive training before heart surgery to protect memory
This trial tests whether brain-focused cognitive training before elective heart surgery can help reduce memory and thinking problems afterward. If you qualify, you may do language-based thinking exercises and complete short brain tests around the time of surgery.
Bad NauheimAges 18 years+ - NCT04576793RecruitingPhase 2
Imaging brain inflammation in Alzheimer’s and related variants over time
This Phase 2 study uses repeated brain MRI scans to track “microglial activation,” which is a marker of brain immune/inflammation activity, in different Alzheimer’s-related conditions. It may help researchers understand how brain inflammation changes over time and differs between people with these clinical variants.
New York, New YorkAges 50 years+ - NCT04509102Enrolling by invitationEarly Phase 1
Test added stimulant medicine with rTMS for depression
This early study tests whether adding a stimulant medicine to repetitive TMS (a non-drug brain stimulation) can improve depression. It is aimed at people whose depression has not improved after at least two antidepressant tries.
Los Angeles, CaliforniaAges 18–65 - NCT04570085RecruitingPhase 3
Caffeine treatment to improve thinking in Alzheimer’s disease
This trial tests whether changing caffeine intake can improve thinking and brain function in people with Alzheimer’s disease. You may qualify if you can follow a low-caffeine diet and have stable Alzheimer’s treatment and sleep/heart conditions.
AmiensAges 50 years+ - NCT04579120Recruiting
Brain scan study in healthy aging or early Alzheimer’s
This study uses brain imaging to understand changes in the brain during normal aging and early Alzheimer’s disease (AD). It may help researchers spot early brain changes and evaluate how well imaging measures those changes.
St Louis, MissouriAges 18 years+ - NCT04580134RecruitingPhase 4
Clozapine study for people with a specific schizophrenia or bipolar type
This trial tests whether clozapine works better for people whose illness fits a specific “biotype-1” pattern. It may help reduce ongoing symptoms, but it also requires close safety monitoring.
Hartford, ConnecticutAges 18–60 - NCT04526093Recruiting
Study of medical cannabis using patient symptom reports
This study looks at how medical cannabis affects symptoms like pain, epilepsy, sleep, and anxiety or depression, based on what patients report over time. It may help researchers understand what works in real life when people use verified medical cannabis products.
Toronto, OntarioAges 19 years+ - NCT04588233Recruiting
Melatonin study for teens with sleep trouble
This study tests whether melatonin can help teens (ages 13–17) who have trouble sleeping. You may be able to join if you’ve never taken melatonin before and your sleep issue seems to be behavior-related rather than caused by another medical sleep problem.
Loma Linda, CaliforniaAges 13–17 - NCT04529031Recruiting
Study of reminder-based positive thinking for teens with PTSD
This study looks at whether a “reminder-focused positive thinking” approach can help teens with PTSD. It may benefit you by testing how certain cues and supportive thoughts affect PTSD symptoms and related wellbeing.
Los Angeles, CaliforniaAges 11–15 - NCT04550377RecruitingPhase 2
Cannabidiol for PTSD, including PTSD after mild head injury
This Phase 2 study tests whether cannabidiol (CBD) can reduce PTSD symptoms, including in people who also had a mild traumatic brain injury (TBI). It’s meant to see if CBD is helpful and safe for PTSD symptoms over the study period.
New York, New YorkAges 18–70 - NCT04588285RecruitingPhase 2
Ambroxol for new and early dementia with Lewy bodies
This trial tests whether ambroxol (a mouth medicine) can help people with new or early dementia with Lewy bodies (DLB) or mild cognitive impairment linked to DLB. Participants take the medicine for about 18 months while the study tracks safety and changes over time.
Haugesund, HaugesundAges 50–85 - NCT04516057RecruitingPhase 3
Tested medicine nabilone for agitation in Alzheimer’s dementia
This Phase 3 trial studies whether nabilone can reduce agitation (restlessness, anger, or difficult behavior) in people with Alzheimer’s dementia. It’s designed for older adults who already have agitation despite standard dementia care.
Calgary, AlbertaAges 55 years+ - NCT04572321Enrolling by invitation
Teen depression and suicide research study for youth
This study looks at depression and suicidal thoughts or behaviors in children and teens. It may help researchers better understand these risks and improve supports for young people.
Dallas, TexasAges 8–20 - NCT03036319Recruiting
Neurorehabilitation study for thinking and memory changes
This study looks at neurorehabilitation approaches for people age 50 and older who report trouble with thinking or memory. It may help researchers understand how to support cognitive functioning during recovery or daily life.
Ann Arbor, MichiganAges 50 years+ - NCT04452500RecruitingPhase 2
Study drug for PTSD symptoms in Veterans
This trial tests a study medicine that blocks the effects of cortisol (a stress hormone) to reduce PTSD symptoms in Veterans. It’s meant for people with ongoing PTSD symptoms and stable treatments, and it closely checks safety because the medicine can affect sleep, mood, and heart rhythm.
