What is CADASIL?

CADASIL (Cerebral Autosomal Dominant Arteriopathy with Sub-cortical Infarcts and Leukoencephalopathy) is a rare, inherited form of cerebrovascular disease that occurs when the thickening of small blood vessel walls in the brain’s white matter blocks the flow of blood to the brain. It is the most common hereditary condition leading to small-vessel vascular cognitive impairment and dementia.

CADASIL Testing

A genetic blood test is considered the gold standard for diagnosing CADASIL. Testing indicated when clinical findings (migraines with early-onset strokes and dementia), MRI findings, and family history raise a high index of suspicion.

Doctor Directory

Finding the right healthcare provider can be a challenge when you have a rare disease like CADASIL. Since 2012, we have been reaching out, educating doctors about CADASIL. This year we are putting CADASIL information into the hands of providers to support the families they serve.

CADASIL Support

cureCADASIL hosts several local meet ups and encourages others to reach out to CADASIL families near you. This local networking can be a source of support for you as well as a springboard for local advocacy for CADASIL.
