Scientists launch Decade-Long quest to unravel rare stroke disorder

This study follows 155 adults with CADASIL, a genetic condition that narrows small blood vessels and raises the risk of strokes and dementia, over nine years. Researchers will use brain scans, blood tests, and other exams to track how the disease changes blood vessels and thinking abilities. Healthy volunteers also participate for comparison. The goal is to better understand the disease's progression, not to test a new treatment.
