Building a network to better diagnose rare brain blood vessel diseases

This trial is building a large clinical network across Italy to help doctors better recognize and diagnose rare brain blood vessel diseases—conditions like CADASIL, Moyamoya disease, Sneddon syndrome, Fabry disease, and COL4A1 syndrome. Many patients with these conditions are misdiagnosed or have difficulty accessing specialists because most experts are concentrated in northern Italy. By connecting patients and specialists in a coordinated network, this study aims to improve diagnosis, understand how these diseases develop, and eventually help all patients in Italy receive better care.

More than 30% of strokes have unknown causes, and rare brain blood vessel diseases are a significant part of this puzzle—yet they are often missed by doctors who aren't familiar with them. This network exists to overcome the challenge that specialized care for these diseases is currently available only in a few centers in northern Italy, leaving many patients with long, expensive journeys for diagnosis and care.
