We’re tracking 37 recruiting cognitive impairment studies with a site in California — including Phase 1, Phase 2 and Phase 4 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT06918704Recruiting
Digital brain health program for older adults
This study tests a digital program designed to help support thinking and memory in older adults. It may be a good fit if you are 60+ and generally healthy, even if you have some mild memory concerns.
San Francisco, CaliforniaAges 60–85 - 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 - NCT06580002RecruitingPhase 2
Can Riluzole Help with Chemo Brain? A Pilot Study
This study tests if a medicine called riluzole (currently used for ALS) can help with 'chemo brain' – memory and thinking problems after cancer treatment. It is for people who feel their mental sharpness has declined after breast cancer therapy, certain chemotherapies, or brain radiation.
Orange, 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+ - NCT06502964RecruitingPhase 2
ALTO-101 study for schizophrenia cognitive symptoms
This study tests an experimental medication called ALTO-101 for people with schizophrenia who also have cognitive impairment (memory or thinking problems). It aims to see if the drug can improve these symptoms while you continue your current antipsychotic treatment.
Garden Grove, CaliforniaAges 21–55 - NCT06090578Recruiting
Brain health check for adults in primary care
This trial tests a new brain health assessment tool in primary care clinics. It may help your doctor better detect thinking or memory changes early.
Pasadena, CaliforniaAges 18 years+ - NCT06023446Enrolling by invitation
Can eye photos detect early Alzheimer's disease?
This study uses a special camera (OCT) to take pictures of the retina (the back of your eye) to see if it can detect Alzheimer's disease very early. You may be eligible if you are either cognitively normal or have mild cognitive impairment, and have already had a test for Alzheimer's-related brain changes.
Sacramento, CaliforniaAges 50–89 - NCT05929703Recruiting
Caring for hospitalized older adults
This study tests a new approach to caring for older adults in the hospital to prevent confusion (delirium). It involves having a family member or care partner stay with the patient during the hospital stay.
Orange, CaliforniaAges 70 years+ - 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.
Walnut Creek, CaliforniaAges 55–90 - 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.
San Francisco, CaliforniaAges 60–85 - NCT05215886Enrolling by invitation
Bariatric surgery and memory problems in people with obesity
This study looks at how bariatric (weight-loss) surgery may affect memory and thinking in people with obesity who already have memory decline or dementia. It may help doctors understand which patients benefit most and what changes to expect.
Sacramento, CaliforniaAges 18–75 - NCT04804241RecruitingPhase 2
Senicapoc for early Alzheimer’s symptoms
This Phase 2 study tests whether the drug senicapoc can slow or improve symptoms in people with early Alzheimer’s disease or mild memory impairment. You would have a 50/50 chance of getting senicapoc or a placebo (inactive pill), along with regular study visits and testing.
Sacramento, CaliforniaAges 55–85 - 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.
Fresno, CaliforniaAges 75 years+

What taking part in a 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.

Common questions
- Are there cognitive impairment clinical trials in California?
- Yes. We're currently tracking 37 recruiting cognitive impairment studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a cognitive impairment study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a cognitive impairment trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New cognitive impairment studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
