“…In addition, arterial stiffness is correlated with white matter damage, as indicated by MRI measures (structural and diffusion tensor imaging). This is consistent with the idea In a separate study based on our original 55-to 87-year-old sample, 69 we also investigated whether pulse-DOT parameters were sensitive to cerebral vasodilation and vasoconstriction manipulations. Vasodilation should generate a reduction in peripheral resistance, and as such it should also be associated with a reduction of pulse amplitude in the brain.…”

“…For instance, reduced efficiency of top‐down control mechanisms (e.g., CRUNCH, Reuter‐Lorenz & Cappell, ) can incorporate both reduced structural/functional connectivity and increased frontal and bilateral cortical recruitment at lower levels of cognitive load in older adults (see Schneider‐Garces et al, ). Importantly, declines in prefrontal cortex tissue and cognitive control performance in older adults are increasingly shown to vary with the presence of modifiable cardiovascular and cerebrovascular factors (e.g., Chiarelli et al, ; Fabiani, Gordon et al, ; Fabiani, Low et al, ; Jolly et al, ; Tan et al, ; Zimmerman et al, ) and to be, at least partly, mitigated by cardiorespiratory fitness (Fletcher et al, ; Gordon et al, ; Kramer et al, ). Exercise intervention programs appear to stave off, if not reverse, some of the declines in cognitive control found in older adults (Bherer, Erickson, & Liu‐Ambrose, ; Colcombe & Kramer, ; Gajewski & Falkenstein, ; Heyn, Abreu, & Ottenbacher, ; Smith et al, ) and more recently in inactive children (Chaddock et al, ; Hillman, Erickson, & Kramer, ).…”

“…In this cohort, AChEI use was significantly higher among the AD group, and could account for the blunted HR response to the language task. A number of recent studies have demonstrated that changes in CBFv are likely to be as a result of changes occurring at the metabolic or myogenic level in response to cognitive [ 28–30 ], or motor [ 31 ] stimulation. This challenges the interpretation that CBFv changes are purely a reflection of changes in MAP [ 23 ].…”
