Retinal Vasoreactivity is a Marker for Cerebral Small Vessel Disease Progression
Mayo Clinic
Summary
Cerebral small vessel disease (SVD), present in 80-94% of adults over age 65 years, increases the risk of stroke by 2-fold, and dementia by 2.3-fold. There is currently no treatment to slow SVD progression. This study aims to test whether impaired cerebral and retinal vasoreactivity may serve as biomarker for SVD progression, and to evaluate the safety and efficacy of cilostazol (antiplatelet agent with vasodilatory and anti-inflammatory properties) for the treatment of SVD.
Description
This is a prospective, observational nested pilot randomized controlled study to discover retinal biomarkers that would predict cerebral small vessel disease progression, and evaluate the safety/efficacy of cilostazols in slowing SVD progression. Twenty CADASIL, 40 sWMD, 20 lobar CMB, and 20 age-matched healthy controls from the Mayo Clinic Florida Familial Cerebrovascular Disease Registry and neurology clinic will be recruited. All participants will undergo OCTA retinal scan, MRI-BOLD brain scan, cognitive battery evaluation, and blood sample at baseline and a 12-month follow-up visit. Key ou…
