Arterial stiffness and cerebral hemodynamic pulsatility during cognitive engagement in younger and older adults.

CONCLUSIONS: Older adults experience increases in large artery stiffness during cognitive engagement possibly preventing effective buffering of pulsatile hemodynamic energy entry into the cerebrovasculature. This is important as pulsatile flow during cognitive engagement, and not mean flow per se, was related to overall cognitive performance. PMID: 29129735 [PubMed - as supplied by publisher]
