How thinking problems affect pain in breast cancer survivors
This study looks at whether mild memory or thinking issues after breast cancer treatment are linked to ongoing pain. If you join, you will help doctors understand this connection, which may lead to better pain care.
Boulogne-Billancourt, IDEAges 35–65 - NCT07764679RecruitingPhase 3
Brain scan to detect Alzheimer's plaques
This study tests a new PET brain scan that uses a special dye to show amyloid plaques, which are linked to Alzheimer's disease. It may help doctors see if your memory problems are caused by Alzheimer's or something else.
Beijing, Beijing MunicipalityAges 40 years+ - NCT07287852Enrolling by invitationPhase 2
Ginkgo biloba extract for mild cognitive impairment
This trial tests whether a specific ginkgo biloba extract (EGb761) can improve thinking and memory in people with mild cognitive impairment (MCI). It also looks at changes in blood markers related to the condition.
JerusalemAges 65 years+ - NCT05268861Recruiting
Understanding brain learning after stroke during arm training
This study looks at how thinking and brain processes affect learning to move your arm after a stroke. You may be asked to do arm tasks in a way that helps the researchers understand what helps or limits motor learning.
Laval, QuebecAges 40–75 - NCT06950190Enrolling by invitationPhase 3
Exercise and thinking skills during chemotherapy
This study tests whether a structured exercise program can help protect thinking and memory in adults receiving chemotherapy for cancer. If you are able to walk on your own and do light exercise, this trial might be a good fit.
Schenectady, New YorkAges 18 years+ - NCT06547099Recruiting
Understanding new blood markers in memory loss and dementia
This study is looking for older adults (60+) to help researchers better understand how to detect and track memory changes and dementia. Participants will provide blood samples and other health information over time to identify new markers that might help with early diagnosis.
St Louis, MissouriAges 60 years+ - NCT05336201RecruitingPhase 2
Brain training program for teens with sickle cell disease
This Phase 2 study tests a cognitive (thinking) training program to help teens with sickle cell disease prepare for the changes in their care as they grow older. It may help with skills like learning, attention, and planning for transition to adult care.
Birmingham, AlabamaAges 10–18 - NCT07731087Recruiting
Stem cell secretion therapy for thinking recovery after stroke
This study tests whether a therapy made from stem cell secretions can help improve memory and thinking after an ischemic stroke. It is for people who had a clot-related stroke in the past 3 months and now have mild to moderate cognitive issues.
Makassar, South SulawesiAges 40–75 - NCT07657624Recruiting
Heart disease and memory problems risk study

Beijing, ChinaAges 18 years+ - NCT05655325Recruiting
Exercise program to improve thinking in older adults with mild memory trouble
This study tests whether a supervised exercise plan can improve executive thinking (like planning and task control) in older adults with mild cognitive impairment. Researchers also look for brain changes using an MRI.
Washington D.C., District of ColumbiaAges 55 years+ - NCT03542734Recruiting
Imaging study for thinking and brain changes in older adults
This study looks at brain scans and eye/eye-nerve findings to understand why thinking can change with aging. It may help researchers connect eye and brain changes, which could guide future ways to prevent or detect dementia early.
HangzhouAges 40 years+ - NCT07298876Enrolling by invitation
Ultrasound for memory and sleep in early Alzheimer's
This study tests if a gentle ultrasound treatment to the brain can help improve memory and sleep quality in people with very early Alzheimer's disease. If you have mild memory issues and trouble sleeping, this low-intensity approach might be a safe option to explore.

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.
