Sacramento, CaliforniaAges 55–85 - 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.
Irvine, CaliforniaAges 55–90 - 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.
Long Beach, CaliforniaAges 75 years+ - 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 - NCT05625425Recruiting
Study testing a memory and wayfinding training program
This study tests a wayfinding (getting around) training program and how it may affect long-term memory. You may need brain scans (fMRI), virtual reality tasks, and regular short walks to participate.

Pasadena, CaliforniaAges 18 years+ - NCT06548191RecruitingPhase 1
Time-Restricted Eating for Alzheimer's Disease
This study tests whether a time-restricted eating schedule (eating all meals within a 10-hour window each day) can improve memory and thinking in people with early Alzheimer's disease or mild cognitive impairment. Healthy partners of people with memory problems can also join as a comparison group.
San Diego, CaliforniaAges 60 years+ - NCT06916221Recruiting
Digital brain training in aging
This study tests whether a digital intervention can help older adults (60+) maintain or improve cognitive function. It is designed for healthy adults or those with mild cognitive impairment (MCI), and people who do not regularly play a musical instrument or have extensive music training.
San Francisco, CaliforniaAges 60–85 - NCT06918704Recruiting
Digital brain health program for older adults

What taking part in a mild cognitive impairment 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.
