Abstract

Introduction:Medin, an aging-associated amyloidogenic protein, induces cerebrovascular dysfunction and inflammation. We investigated the relationship between cerebrovascular medin and Alzheimer's disease (AD) and vascular dementia (VaD). Methods:Cerebral arteriole medin was quantified from 91 brain donors with no dementia (ND), AD, VaD, or combined AD and VaD. Correlation analyses evaluated the relationship between arteriole medin, and plaques, tangles, or white matter lesions (WML). Receiver operating characteristic and regression analyses assessed whether medin is predictive of AD or VaD versus other cerebrovascular pathologies (circle of Willis [CoW] atherosclerosis and cerebral amyloid angiopathy [CAA]). Results:Arteriole medin was higher in those with AD, VaD, or combined AD/VaD versus ND (P < .05), and correlated with tangle, plaque, and WML, but not CAA or CoW atherosclerosis. Among cerebrovascular pathologies, medin was the strongest predictor of AD diagnosis, whereas CoW atherosclerosis and arteriole medin were predictors of VaD. Discussion:Cerebral arteriole medin is associated with and could be a potential novel risk factor or biomarker for AD and VaD.
