Cerebral Autosomal Dominant Arteriopatie With Subcortical Infarcts and Leukoencephalopathy

K-CADASIL is a 10-year prospective study of 500 Korean patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), a genetic brain disease that causes stroke and dementia. The investigators will track symptoms, brain scans, memory tests, and gene information to understand disease progression in Koreans and identify better treatments. Participants will visit clinics regularly for check-ups and blood tests. This study aims to help improve care for CADASIL patients and families worldwide.
