Abstract 34: Association of Carotid Intima-Media Thickness and Other Carotid Ultrasound Features With Incident Dementia in The Atherosclerosis Risk in Communities Neurocognitive Study (ARIC-NCS)

Background: Increased carotid intima-media thickness (cIMT), a measure of carotid artery thickness, and carotid plaque are predictors of cardiovascular disease and atherosclerosis. Likewise, increased interadventitial diameter (IAD), which references arterial remodeling, and lower carotid distensibility coefficient (DC), which indicates carotid stiffness, are also predictors. These indices likely relate to cerebrovascular disease, and thus may...
