Figure 1 A (r 1⁄4 -0.649, P < 0.001). Increase in CVR with age is shown in Figure 1 B (r1⁄4 0.259, P< 0.05). Reduction in nTBVwith agewas correlated negatively with increases in CVR (r1⁄4 -0.344, P < 0.01) (Figure 1 C). However, no age-related differences in nTCBF were observed (r 1⁄4 0.03, P 1⁄40.815) (Figure 1 D). Conclusions: Increases in cerebrovascular resistance with age suggest the presence of cerebral vasoconstriction and/or vascular rarefaction which may be related to the reduction in brain tissue volume. However, no age-related differences in normalized brain perfusion indicate that neurovascular coupling is likely to be maintained intact during normal aging.
