Why the study?
Does cognitive engagement alter carotid artery stiffness and hemodynamic pulsatility in healthy adults?
Does cognitive engagement alter carotid artery stiffness and hemodynamic pulsatility in healthy adults?
Cognitive engagement reduces carotid flow pulsatility without altering carotid pressure pulsatility or artery stiffness, suggesting other factors buffer cerebrovascular hemodynamics.
Does not inform clinical carotid assessment; leaves open mechanisms buffering cerebrovascular flow during cognition in pilot data.
Carotid pressure pulsatility is unaltered while carotid flow pulsatility is reduced during cognitive engagement. Carotid artery stiffness does not change suggesting that factors other than the dynamic elastic properties of the CCA buffer cerebrovascular hemodynamic pulsatility during cognitive engagement.
