A connection between Alzheimer's disease (AD) and endothelium pathology has been inferred from measured decreases in both blood flow and metabolism in the parietal and temporal cortex. However, it is not known whether these alterations are seen in normal aging. We performed regional cerebral blood flow (rCBF) measurements in 22 AD patients and in 44 non-demented subjects during a simple test of information...
Apart from the cardiovascular system, several cerebrovascular defense mechanisms inherently function to maintain homeostasis of the neurovascular unit. Prevailing evidence suggests that cerebrovascular functions decline differentially during normal ageing with pronounced effects in Alzheimer's disease (AD). This commentary highlights how vascular regulatory mechanisms may change with age and precede...
