Brain stimulation study for Parkinson's with mild memory issues
This trial tests a type of brain stimulation called iTBS on an area of the brain that may help with thinking and memory problems in people with Parkinson's disease and mild cognitive impairment. If you qualify, you and your caregiver would take part in sessions and answer questions about your daily life.
Charleston, South CarolinaAges 50–85 - NCT05904132Recruiting
Brain stimulation therapy for early Alzheimer’s memory loss
This trial studies a “closed-loop” brain stimulation approach to improve symptoms in people with early Alzheimer’s-related memory problems. It may help by delivering stimulation based on your brain signals, if you meet the safety and diagnosis requirements.
Charlestown, MassachusettsAges 50–80 - NCT04027244Recruiting
Studying care plans for severe leg blood flow problems
This study looks at how best to manage severe leg ischaemia, a condition where blood flow to the leg is dangerously reduced. It mainly involves patients who are planning an intervention, and some participants may also do special heart imaging tests.
Leicester, LeicestershireAges 18–110 - NCT04124029Recruiting
Study how mild brain injuries may relate to dementia
This study looks at how past mild traumatic brain injury may contribute to brain changes seen in chronic traumatic encephalopathy (CTE) and Alzheimer’s disease (AD). It may help researchers understand risk and brain markers by comparing people with mild or moderate TBI, people with mild memory problems, and healthy controls.
Boston, MassachusettsAges 30–90 - NCT04240561Recruiting

This study looks at how much hearing aid outcomes vary in older adults who have Alzheimer’s dementia or mild memory problems. It may help researchers understand what hearing aids work best and for whom.
Chicago, IllinoisAges 50–90 - NCT04262206RecruitingPhase 4
Testing how statins affect outcomes in adults 75 and older
This trial studies whether cholesterol-lowering medicine (a statin, specifically atorvastatin) improves health and benefits in people age 75 and older in everyday life. It may help doctors understand which older adults benefit most and how to use these medicines safely.
Birmingham, AlabamaAges 75 years+ - NCT04396873RecruitingPhase 1
PET brain scan study of inflammation markers in neurodegeneration
This Phase 1 study tests a PET scan to measure inflammation-related changes in the brain using a medication called ketoprofen. It may help researchers understand which people with certain brain diseases could benefit from treatments aimed at inflammation.
Bethesda, MarylandAges 18–99 - NCT04500847RecruitingPhase 1
Testing repurposed HIV-like drugs for early Alzheimer’s symptoms
This Phase 1 study tests whether an existing type of anti-viral medicine (nucleoside reverse transcriptase inhibitors) can help people with early Alzheimer’s disease. It also focuses on safety and proper dosing while measuring brain-related changes and memory-related symptoms.
Los Angeles, CaliforniaAges 50–85 - NCT04525144RecruitingPhase 2
Test EGb 761 for mild memory loss with brain blood vessel disease
This trial studies EGb 761 to see if it can improve symptoms in people with mild cognitive impairment (early memory/thinking changes) who also have signs of brain blood vessel disease. It may help by targeting the brain changes seen on scans.
SingaporeAges 45–85 - NCT04715984Recruiting
Testing brain-circuit targets during DBS surgery in Parkinson’s
This study looks at how brain connections involved in movement may relate to thinking and memory problems in Parkinson’s disease. It happens during a deep brain stimulation (DBS) operation, using tests while the surgeon is placing an electrode.
Nashville, TennesseeAges 40 years+ - NCT04722939Recruiting
Testing brain function outcomes after ICU kidney failure treatment
This trial studies how treating severe kidney injury in the ICU may affect patients’ brain and thinking function over time. It compares measurements of brain activity and function after starting kidney replacement therapy.
Kingston, OntarioAges 18 years+ - NCT04804618Recruiting
Study uses blood protein changes in memory loss and Alzheimer’s
This trial studies blood “protein fingerprints” in people with mild memory problems or Alzheimer’s disease to better understand what’s happening. It may help researchers find ways to measure the condition and improve care over time.
Guangzhou, GuangdongAges 55 years+ - NCT04906863Recruiting
Genetic study for early dementia in adults and families
This trial studies genes to better understand why some people develop dementia and memory problems earlier in life. It may help researchers find clearer causes and improve future testing and treatments for families affected by dementia.
New York, New YorkAges 35 years+ - NCT04946916Recruiting
Testing blood/brain marker levels and thinking problems in psychiatric illness
This study looks at neurofilament light (a brain/nerve injury marker) and how it relates to thinking and memory problems in people with certain psychiatric conditions. It may help researchers understand brain changes and cognitive impairment, which could guide better diagnosis in the future.
BronAges 45–80 - NCT05016219Recruiting
Light therapy to improve sleep and thinking in early Alzheimer’s
This trial studies rhythmic light therapy to help people with early Alzheimer’s or mild memory problems, especially when sleep is getting worse. If you fit the sleep and vision/medical safety requirements, the study may see whether the therapy improves sleep and thinking-related symptoms.
Menands, New YorkAges 55 years+ - NCT05065450Recruiting
Testing whether brain stimulation improves memory in epilepsy
This trial looks at ways to improve memory by targeting specific deep brain areas in people with epilepsy. You may be eligible if you are already scheduled for long-term video monitoring with implanted depth electrodes in the memory-related regions (amygdala, hippocampus, and nearby areas).
St Louis, MissouriAges 18–75 - NCT05151562Recruiting
Music therapy for people with early Alzheimer’s or memory loss
This trial studies whether music therapy can improve symptoms and well-being in people with early Alzheimer’s disease or mild memory problems. You may take part in music sessions and likely be screened with MRI, so the study checks safety for scans.
Baltimore, MarylandAges 18–89 - NCT05230758RecruitingPhase 3
Metformin trial for brain tumor survivors’ brain and behavior
This Phase 3 study tests whether metformin can improve brain function, behavior, and thinking in children and teens who were treated for certain brain tumors. You may be able to join if you meet age, time-since-treatment, language, and health/lab safety requirements.

Barlow-style program for thinking and memory problems after breast cancer
This trial tests a structured “Barlow Protocol” program to help improve mild to moderate thinking and memory problems in people who finished breast cancer chemotherapy. It may help if your cognitive symptoms started after treatment and you’re not already in similar therapy.
CórdobaAges 18–70 - NCT05305092Recruiting
Study of memory and thinking in early breast cancer
This study checks how breast cancer affects memory and thinking before other treatments start. It may help doctors better understand cognitive changes and who is most at risk.
Xi'an, ShaanxiAges Any age - NCT05356611Recruiting
Study for depression and mild memory thinking problems
This trial tests a program aimed at helping older adults with depression who also have mild thinking and memory difficulties. You may be asked to complete study sessions and tracking, with support for depression symptoms and thinking function.

Protecting the brain during a heart procedure for atrial fibrillation
This trial studies a way to help protect the brain during a catheter procedure that closes the left atrial appendage (a small heart pouch) in people with atrial fibrillation. It may help lower the risk of stroke-related brain injury for patients who can’t safely take blood thinners.

Common questions
- Are there clinical trials for cognitive impairment?
- Yes. Clin2 currently lists 575 recruiting cognitive impairment studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a cognitive impairment trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a cognitive impairment trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
