Cerebral amyloid-β (Aβ) plaques are the hallmark biomarker of Alzheimer's disease (AD) and are detectable decades before clinical symptoms. Modifying risk factors associated with Aβ accrual offers an opportunity for AD prevention. While midlife vascular health is linked to AD; there is minimal longitudinal evidence regarding the effect of midlife lipids on Aβ. We examined the association between midlife lipids and Aβ 20 years later. One hundred and twenty-two women had serum lipid profiles in midlife (1992, 45-57 years), and cerebral imaging, genotyping, and cognition measured 20 years later (2012/13, 66-77 years). Imaging was performed in 2012/13 via F-18 Florbetaben positron emission tomog..
