We’re tracking 36 recruiting dementia studies with a site in California — including Phase 2, Phase 2/Phase 3 and Phase 4 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT03638583Recruiting
Online testing study to prevent or spot Alzheimer’s early
This study invites people age 50+ who do not have dementia to do ongoing thinking tests online. If an online risk screen suggests you may be at higher risk, you may be referred for in-person body tests (biomarker assessment).
San Diego, CaliforniaAges 50–85 - NCT06741865Recruiting
Helping older adults keep their minds sharp (INSPIRE-Faith)
This trial tests whether certain lifestyle and thinking exercises help preserve memory and brain function in older adults, especially in the African American community. You may join if you are 55 or older and your memory is normal or mildly impaired.
Los Angeles, CaliforniaAges 55–85 - NCT06647498RecruitingPhase 2/Phase 3
Study of a treatment for early-onset Alzheimer's caused by a gene change
This study tests a potential disease-modifying treatment for people who have a specific gene mutation that causes early-onset Alzheimer's disease. The goal is to see if the treatment can delay or prevent symptoms.
Los Angeles, CaliforniaAges 18 years+ - 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+ - NCT06052254RecruitingPhase 2
Skin patch for agitation in Alzheimer's dementia
This trial tests a skin patch that delivers a medicine called dexmedetomidine to help calm agitation in people with Alzheimer's disease. It might be an option for those living in a care facility who have had recent episodes of agitation.
Chino, CaliforniaAges Any age - 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 - NCT05552157RecruitingPhase 2/Phase 3
Study of treatments for early onset Alzheimer's caused by genetic mutations
This trial tests potential treatments for people who are at risk for or have early onset Alzheimer's disease due to a specific genetic mutation. It aims to find treatments that could slow or prevent symptoms.
Los Angeles, CaliforniaAges 18 years+ - NCT04916210Recruiting
Study how stroke type affects thinking and recovery
This study looks at what predicts memory and thinking problems after different types of stroke or brain bleeding, and how blood-vessel changes relate to recovery. You may be invited if you recently had a stroke/bleed and can complete a baseline check within 6 weeks.
Los Angeles, CaliforniaAges 18 years+ - 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+ - 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.
Orange, CaliforniaAges 25–55 - NCT03623672Enrolling by invitation
Study for early signs of Parkinson-related brain changes
This study enrolls people with idiopathic REM sleep behavior disorder, a sleep problem that can come before Parkinson’s disease or related conditions. It aims to better understand early (“prodromal”) changes so future treatments can be targeted earlier.
Redwood City, CaliforniaAges 18 years+ - NCT03489278Recruiting
Support procedures study for ALS using electronic health records
This study is about improving the research process for people with ALS by using electronic health records from participating clinics. If you have ALS and receive care at an Epic-using center, you may be asked to help with consent and study procedures.

What taking part in a dementia 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 dementia clinical trials in California?
- Yes. We're currently tracking 36 recruiting dementia 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 dementia 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 dementia 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 dementia 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.
