Hughes, PhD, of the University of Pittsburgh. The study involved 91 people with an average age of 87 who did not have dementia. Researchers took scans of the participants’ Half of all participants had beta-amyloid plaques. People with beta-amyloid plaques were more likely to have high systolic blood pressure, higher average blood pressure and higher arterial stiffness as measured with the brachial-ankle method. For every unit increase in brachial-ankle arterial stiffness, people were twice as likely to have beta-amyloid plaques in the brain. Arterial stiffness was highest in people who had both amyloid plaques and white matter hyperintensities in the brain, or brain lesions. “These two conditions may be a ‘double-hit’ Hughes noted that the relationship between arterial stiffness and amyloid plaque was not changed when regular resting blood pressure was taken into account. “This study adds to growing evidence that hardening of the arteries is associated with cerebrovascular disease that does not show symptoms. Now we can add Alzheimer’s type lesions to the list,” Hughes said. The study was supported by the National Institutes of Health and the National Institute on Aging.
