Image-guided focused radiation to protect thinking in brain metastases
This Phase 2 trial tests a brain radiation technique that aims to treat up to a few brain metastases while sparing areas important for thinking and memory. It may help people keep cognitive abilities better than with more brain-wide radiation approaches.
San Diego, CaliforniaAges 18 years+ - NCT04171323Recruiting
Active mind training to improve thinking and delay dementia

What taking part in a cognitive function 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 function clinical trials in California?
- Yes. We're currently tracking 12 recruiting cognitive function 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 function 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 function 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.
