Home-based exercise to help brain tumor survivors with thinking and memory
This study tests whether a virtual home-based exercise program can improve thinking and memory problems caused by brain tumor treatment in teens and young adults. It also looks at how exercise affects gut health.
Atlanta, GeorgiaAges 15–39 - NCT05282550RecruitingPhase 2
Trazodone trial to improve sleep in early Alzheimer’s

Baltimore, MarylandAges 55 years+ - NCT06290167Recruiting
Dual-task rehab for memory concerns in older adults
This study tests a new rehab program that combines physical and mental tasks for older adults with early memory issues. It aims to help improve daily function and possibly slow decline.
Milan, MIAges 65 years+ - NCT06013579Recruiting
Exercise study for older adults with HIV
This study tests whether high-intensity exercise can help improve thinking and memory, and build lasting exercise habits, in older adults living with HIV who feel tired and are not very active.
Birmingham, AlabamaAges 50–80 - NCT06336174Recruiting
Thinking and Memory in Brain Artery Narrowing: A Study
This study looks at how severe narrowing of brain arteries may affect memory and thinking over time. It involves people who have had a mini-stroke or mild stroke and aims to understand the changes in cognitive function.
Hefei, AnhuiAges 18–80 - NCT05663034Recruiting
Compare CBT-I vs MBTI for sleep and trauma symptoms after TBI
This study compares two types of talk-based therapy to help veterans with long-lasting insomnia after a traumatic brain injury (TBI), and also looks at related post-trauma stress symptoms. It may help you improve sleep and reduce how much these symptoms affect daily life.
Eglin Air Force Base, FloridaAges 18 years+ - NCT05976152RecruitingPhase 3
Butyphthalide to improve thinking after a recent stroke
This Phase 3 study tests whether butyphthalide can help thinking and memory improve after an acute ischemic stroke. It compares people who take the study medicine versus usual care, and measures cognitive (thinking) changes over follow-up.
Dandong, LiaoningAges 60 years+ - NCT07042087Recruiting
Brain health lifestyle study: timed eating and mindfulness
This study tests whether a combination of time-restricted eating and mindfulness can help protect brain health in people with early memory concerns. It lasts 9 months and includes regular guidance and support.
BrnoAges 60–80 - NCT05895344Recruiting
Compare proton vs modern radiation effects on thinking
This study compares two types of radiation—proton therapy versus modern fractionated radiation—to see how they affect long-term thinking (cognitive function) and daily abilities in people with a specific skull-base tumor. It may help clarify which radiation approach best protects brain and nerve function over time.
CaenAges 18–70 - NCT03233646Recruiting
Retina scans in memory and nerve disorders
This study uses pictures of the back of your eye (retinal imaging) to look for differences in people with neurodegenerative diseases and compares them with people without these conditions. It may help researchers understand eye changes that could connect to brain or nerve health.
Durham, North CarolinaAges 18 years+ - NCT06120361Recruiting
Primary care study for early cognitive decline
This research study looks at people who have noticed problems with memory or thinking (like trouble focusing or finding words) and visit their primary care doctor for help. It aims to better understand and diagnose conditions that cause these symptoms, such as Alzheimer's disease.
MalmöAges 40 years+ - NCT03702907Recruiting
Study of aging and a brain sample bank
This study follows adults as they age and may collect biological samples for future research. It could help researchers understand early and late changes related to aging and brain health.
Washington D.C., District of ColumbiaAges 45 years+ - 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 - NCT05399745Recruiting
Study of biliary atresia in children with heart disease
This trial is studying children who have biliary atresia, a serious liver problem, including some who also have tetralogy of Fallot (a congenital heart condition). It also includes healthy children for comparison, and may help researchers understand the illness and treatments better.
CopenhagenAges birth–18 years - NCT02420470Recruiting
An early warning system for diabetic brain changes
This study tests whether an “early warning” approach can detect early changes in the brain related to diabetes before serious problems happen. If you qualify, you may be asked to take part in brain and health assessments to see how well the system works.
Xi'an, ShaanxiAges 40–65 - 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 - NCT05597410Recruiting
Study of people at risk for Alzheimer’s in Shanghai
This study follows people who are closely related to someone diagnosed with Alzheimer’s to see who develops memory or brain changes over time. It may help researchers understand risk and early signs, which could guide prevention in families like yours.
Shanghai, Shanghai MunicipalityAges 50 years+ - 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 - NCT05858255Recruiting

Common questions
- Are there clinical trials for cognitive impairment?
- Yes. Clin2 currently lists 571 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.
