CADA-PRO: A Patient Questionnaire Measuring Key Cognitive, Motor, Emotional, and Behavioral Outcomes in CADASIL

Cerebral small vessel disease (cSVD) of ischemic type, either sporadic or genetic, as cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), can impact the quality of daily life on various cognitive, motor, emotional, or behavioral aspects. No instrument has been developed to measure these outcomes from the patient's perspective. We thus aimed to develop and validate a patient-reported questionnaire.
