It is not well known whether subclinical atherosclerosis is an independent risk factor for lower cognitive function among individuals without clinically evident CVD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We examined cross\u2010sectional associations between subclinical atherosclerosis and cognitive function in a community\u2010based sample of otherwise healthy adults with plasma homocysteine \u22658.5\u2009\u00b5mol\/L enrolled in the BVAIT study (<jats:italic>n<\/jats:italic>\u2009=\u2009504, mean age 61 years). Carotid artery intima\u2010media thickness (CIMT), coronary artery calcium (CAC) and abdominal aortic calcium (AAC) were used to measure subclinical atherosclerosis. Cognitive function was assessed with a battery of neuropsychological tests. A principal components analysis was used to extract five uncorrelated cognitive factors from scores on individual tests, and a measure of global cognition was derived. Multivariable linear regression was used to examine the association between subclinical atherosclerosis and cognitive function, adjusting for other correlates of cognition.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Increasing thickness of CIMT was associated with significantly lower scores on the verbal learning factor (<jats:italic>\u03b2<\/jats:italic>\u2009=\u2009\u22120.07 per 0.1\u2009mm increase CIMT [SE(<jats:italic>\u03b2<\/jats:italic>)\u2009=\u20090.03], <jats:italic>p<\/jats:italic>\u2009=\u20090.01).

The association between CIMT and poor verbal learning may pertain particularly to men.
