What is CADASIL?

CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) is a rare genetic disease affecting the small blood vessels of the brain.  It leads to a poor irrigation of certain areas of the brain which causes symptoms that vary from person to person.   CADASIL affects just as many men as women.
