St Louis, MissouriAges 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+ - NCT07177352RecruitingPhase 3

St Louis, MissouriAges 50–90 - NCT05704309Enrolling by invitation
Study of diabetes prevention participants using brain scans
This study looks at how people who previously took part in a diabetes prevention program are doing over time, including brain health using MRI scans for some participants. It may help researchers understand who is at higher risk for memory and thinking problems and why.
St Louis, MissouriAges Any age - NCT06372821RecruitingPhase 1
Study of NIO752 for Alzheimer's disease
This study tests an experimental drug called NIO752 to see if it can reduce the production of tau protein, which is linked to Alzheimer's disease. Researchers will measure how the drug affects tau in your body using a special technique called SILK.
St Louis, MissouriAges 21–80 - NCT06585787RecruitingPhase 3
Testing KarXT for psychosis in Alzheimer’s disease
This study tests an investigational medication (KarXT) for treating psychosis—hallucinations or delusions—in people with Alzheimer’s disease. It aims to see if the drug can reduce these symptoms safely and effectively.
St Louis, MissouriAges 55–90 - NCT05617014Enrolling by invitation
ADNI4 study for early Alzheimer’s with brain imaging tests
This study enrolls people with no memory impairment, mild memory problems, or mild Alzheimer’s dementia to test how brain scans and cognitive tests relate to Alzheimer’s disease. It may help by contributing to better early diagnosis and by letting you see whether you fit into the study’s imaging and blood-test pathway.
St Louis, MissouriAges 55–90 - NCT04629547RecruitingPhase 2
Sleep study to help prevent Alzheimer’s disease
This trial tests whether treating sleep issues and measuring sleep can help lower the risk of Alzheimer’s disease before it starts. It focuses on older adults with no dementia signs yet.
St Louis, MissouriAges 65 years+ - NCT07633470RecruitingPhase 4
Zunveyl for Alzheimer's disease symptoms and caregiver support
This study tests a medication called Zunveyl to see if it helps reduce behavioral and neuropsychiatric symptoms in people with mild-to-moderate Alzheimer's disease, and whether it reduces stress on family caregivers. You would need a confirmed Alzheimer's diagnosis supported by a blood test, and a dedicated caregiver who can attend visits and report on your symptoms.
St Louis, MissouriAges 50 years+ - NCT07169578RecruitingPhase 3
A study of trontinemab for early Alzheimer's disease
This trial tests a new drug called trontinemab for people with early Alzheimer's disease. The goal is to see if it can help slow down memory and thinking problems.
St Louis, MissouriAges 50–90 - NCT05980949RecruitingPhase 3
Long-term safety study of KarXT for Alzheimer's psychosis
This trial tests the long-term safety of an investigational drug called KarXT for people with psychosis caused by Alzheimer's disease. It is for those who have already completed a previous KarXT study and want to continue treatment.
St Louis, MissouriAges 55–90 - NCT06159673RecruitingPhase 2/Phase 3
ACP-204 for Alzheimer's with psychosis
This study tests a new medicine called ACP-204 for people with Alzheimer's disease who also have psychosis (like seeing or hearing things that aren't real). It aims to see if the drug can help reduce these symptoms safely.
St Louis, MissouriAges 55–95 - NCT06274528RecruitingPhase 2
DORA and lemborexant in Alzheimer's biomarkers study
This study is testing whether a sleep medication called lemborexant can improve sleep and reduce Alzheimer's-related proteins in healthy older adults with no memory problems. It could help find new ways to delay or prevent Alzheimer's disease.
St Louis, MissouriAges 65 years+ - NCT00869817Recruiting
Study for adults at risk of inherited Alzheimer’s
This study follows people who are at risk for a specific inherited form of Alzheimer’s disease (because a parent has it). It helps researchers learn how the disease starts and changes over time, especially in people who still feel cognitively normal.
St Louis, MissouriAges 18 years+ - NCT02414178Enrolling by invitation
Tau PET brain scan for inherited Alzheimer’s disease
This study uses a special brain scan to measure “tau” buildup in people with an inherited form of Alzheimer’s. It may help researchers better understand disease changes and evaluate whether the scan can track them over time.
St Louis, MissouriAges 18 years+ - NCT04165109Recruiting
Down syndrome study to test memory and thinking changes
This study enrolls adults with Down syndrome to better understand how thinking and memory develop and change over time. It may help by building a “trial-ready” group and by measuring thinking in a careful, consistent way.
St Louis, MissouriAges 25–55 - 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+ - NCT02414347Recruiting
Tau PET scan study for Alzheimer’s disease
This study uses a PET brain scan with a small injected tracer to look for “tau” protein changes linked to Alzheimer’s disease. It may help researchers better understand how tau appears in people who are cognitively normal or have mild dementia.
St Louis, MissouriAges 18 years+ - NCT04134923Recruiting
Brain PET scan study using a blood-flow and plaque tracer
This study uses PET/CT/MRI imaging to look for brain “imaging biomarkers” in people across the Alzheimer’s disease range. It may help researchers better understand how Alzheimer’s changes the brain over time and improve future treatments.
St Louis, MissouriAges 18 years+ - NCT05077579Recruiting
Alzheimer’s scan study for people with higher body weight
This study uses brain scans (MRI and two special PET scans) to see how Alzheimer’s-related changes show up in people who are overweight or obese, with different blood-sugar and insulin patterns. It may help researchers understand whether body weight and metabolism affect early Alzheimer’s markers in the brain.

What taking part in a alzheimer’s disease study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
