Why the study?
Does higher visit-to-visit variability in blood pressure reduce cognitive function in older adults at risk of cardiovascular disease?
Does higher visit-to-visit variability in blood pressure reduce cognitive function in older adults at risk of cardiovascular disease?
Higher visit-to-visit variability in blood pressure is associated with impaired cognitive function and adverse brain MRI findings in older adults, independent of average blood pressure.
