Biological samples for rare brain and eye vessel diseases
Treatments studied
Part of Blood & lymphatic, Brain & nervous system, Cancer, Genetic & congenital, Heart & circulation clinical trials.
This study collects blood and other biological samples from people with rare diseases affecting the brain's small blood vessels, such as CADASIL, and from healthy volunteers. The samples are used to better understand these diseases and improve future diagnosis and treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have a confirmed diagnosis of a rare brain vessel disease like CADASIL, COL4A1/COL4A2/HTRA1 mutations, moyamoya, cavernoma, or cerebral venous thrombosis.
- You are covered by social security or equivalent health insurance.
- You are willing to provide written consent to participate.
- If you are a healthy volunteer, you must have normal blood pressure (below 140/90 without medication, or below 130/80 if on stable treatment for at least 3 months), no history of stroke or other neurological conditions, no diabetes, and no significant smoking history.

This trial studies CADASIL (a genetic blood-vessel condition in the brain) by following people over time with MRI scans, blood draws, and questionnaires. It may help researchers better understand how the condition changes and how factors like medications affect outcomes.
This study uses MRI scans to look at how well the small blood vessels in the brain work in people with CADASIL, a genetic condition that can cause strokes and cognitive problems. The goal is to develop a new test to better understand and monitor the disease. Participants will have an MRI and may also do simple tasks during the scan.
This study looks at the back of your eyes (the retina) to see if it reflects blood vessel health in the brain. It may help doctors find easier ways to track conditions related to small blood vessel disease.
This study looks at how genetic and brain imaging changes relate to symptoms in people with CADASIL, a genetic condition that affects small blood vessels in the brain and can cause strokes. It aims to better understand the disease to improve future care.
This trial looks at people who may have “small vessel” problems in the brain, which can cause stroke, memory trouble, walking changes, movement symptoms, or headaches. It may help researchers better understand the genetic and non-genetic causes, which could improve future diagnosis and treatment.
This study follows people with CADASIL over time to learn more about the condition. It may help researchers understand how CADASIL progresses and improve care for patients.
