Summary

This study will collect blood samples and medical information from 600 adults with rare diseases affecting blood vessels in the brain and eye, such as CADASIL and cavernous angioma. The goal is to create a long-term biobank that researchers can use to find biomarkers and better understand how these diseases progress. Participants will provide samples and data over time, but this study does not test any new treatments.
