Creation of a Biological Collection for Medical Research Purposes for Patients at the Reference Center for Rare Diseases of the Blood Vessels of the Brain and Eye at Lariboisière Hospital
This study is gathering extra samples, like blood or tissues, from people who have rare conditions affecting the blood vessels in their brains or eyes. The goal is to create a special collection that scientists can use for research. By studying these samples, researchers hope to discover new signs that can predict how these conditions might develop or worsen over time. They also want to find new ways to treat these conditions more effectively. Ultimately, this research aims to improve the care that patients receive and potentially find new medicines or therapies for these rare conditions in the future. This study is for adults over 18 who are already part of a specific group studying these conditions.
At a glance
What is this study about?
Imagine you have a rare condition that affects the blood vessels in your brain or eyes. Doctors and researchers are always looking for better ways to understand what's happening, predict how things might change, and find new treatments. This study is a bit like setting up a special library of clues for researchers to use.
It's called a "biological collection," which simply means gathering extra samples, like blood or tissue, from people who already have these rare brain and eye blood vessel conditions. These samples are like puzzle pieces that researchers can study very carefully. The main goal is to find "biomarkers" – these are like special signals within your body that can tell us more about your condition. For example, a biomarker might help doctors understand if a condition is likely to get worse, or if a particular treatment might work well.
By building this collection, scientists hope to learn more about these rare conditions. They want to find new ways to improve how doctors care for patients and even discover entirely new medicines or treatments. It's important to know that this isn't a trial of a new drug or treatment; it's about collecting information to help future research that could lead to those things.
Key takeaways
- It's for people with rare brain or eye blood vessel conditions.
- The study collects samples like blood for future research.
- It aims to find better ways to understand and treat these conditions.
- No new medicines or specific treatments are involved.
- Participation fits alongside your existing hospital care.
- You can stop participating at any time.
Who may be eligible?
To be part of this study, you need to be an adult, aged 18 or over. You must have already been diagnosed with a rare condition affecting the blood vessels in your brain, such as an inherited form of aneurysm, cerebral amyloid angiopathy, CADASIL, or similar rare conditions of the brain or eye. You also need to be already involved in a specific ongoing study for these conditions (called the MVCR cohort) and be part of the French social security system. You'll also need to sign a consent form, showing you understand and agree to take part.
There are also some reasons why you might not be able to join. For example, if it's not possible for you to continue regular follow-up appointments at the CERVCO centre, this study might not be suitable. Also, if you are pregnant or breastfeeding, you won't be able to join this particular study. People who are under legal guardianship or certain public health benefits in France (AME) are also not eligible.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Do you have a confirmed rare condition of the brain or eye blood vessels?
- Are you already part of the MVCR cohort (a specific group being studied for these conditions)?
- Are you enrolled in the French social security system?
- Are you currently pregnant or breastfeeding? (If yes, you cannot join.)
What does participation involve?
If you decide to take part, it means you'll allow researchers to collect additional samples for their research. These samples are usually collected during your routine medical appointments, so it shouldn't require extra visits just for the study. The study doesn't involve any new medications or specific treatments. The researchers want to follow your condition over a long period, using the samples to understand how rare brain and eye blood vessel conditions change and develop over time. The exact number of samples or the total duration isn't specified, but it's designed to fit in with your existing care at the hospital.

Common questions
What kind of conditions is this study looking at?
This study is for adults with rare conditions that affect the blood vessels in their brain or eyes, like certain types of aneurysms or inherited blood vessel disorders.
Will I have to take any new medicines?
No, this study does not involve testing any new medicines or treatments. It's about collecting samples for research.
What will I actually have to do if I join?
You'll provide additional samples, such as blood, that will be collected during your regular hospital visits. These samples are for research purposes.
Will this study change my medical care?
No, taking part in this study won't change your current medical care. The aim is to help improve future care for people with these conditions.
Can I leave the study if I change my mind?
Yes, you can withdraw from the study at any time, for any reason, and it won't affect the medical care you receive.
