Aortic stiffening increases the risk of incident mild cognitive impairment (MCI) and dementia, according to a recent study. The study included 1,101 dementia-free participants, in whom aortic stiffness was measured and related to the 10-year risk of mild cognitive impairment and dementia. Aortic stiffness was predictive of incident MCI in the entire population, and of incident dementia in people without diabetes.
