If you are a patient with CADASIL, you can volunteer to participate in a research opportunity  with nih.gov. Researchers are examining genetic and physical characteristics of the small vessel disease called CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy). They are enrolling patients with a diagnosis of CADASIL, as well as healthy volunteers to serve as healthy controls. Compensation is provided.
