Cerebrovascular reactivity and cerebral autoregulation are improved in the supine posture compared to upright in healthy men and women.

PLoS ONE, 2020
Cerebrovascular reactivity and cerebral autoregulation are two major mechanisms that regulate cerebral blood flow. Both mechanisms are typically assessed in either supine or seated postures, but the effects of body position and sex differences remain ...

Effects of high intensity interval exercise on cerebrovascular function: A systematic review.

PLoS ONE, 2020
High intensity interval exercise (HIIE) improves aerobic fitness with decreased exercise time compared to moderate continuous exercise. A gap in knowledge exists regarding the effects of HIIE on cerebrovascular function such as cerebral blood velocity ...

Leveraging Function Intersectionality and Multi-Modal Cerebrovascular Reactivity Measures for the Derivation of Individualized Intracranial Pressure Thresholds in Acute Traumatic Neural Injury

Bioengineering
It has been proposed that subject-specific intracranial pressure (ICP) thresholds can be feasibly derived using the relationship between cerebrovascular reactivity and ICP.

Near-Infrared Cerebrovascular Reactivity for Monitoring Cerebral Autoregulation and Predicting Outcomes in Moderate to Severe Traumatic Brain Injury: Proposal for a Pilot Observational Study

JMIR Research Protocols, 2020
BackgroundImpaired cerebrovascular reactivity after traumatic brain injury (TBI) in adults is emerging as an important prognostic factor, with strong independent association with 6-month outcomes.

Cerebrovascular reactivity mapping using intermittent breath modulation

NeuroImage, 2020
Cerebrovascular reactivity (CVR), an index of brain vessel’s dilatory capacity, is typically measured using hypercapnic gas inhalation or breath-holding as a vasoactive challenge.

Cerebrovascular pulsatility index is higher in chronic kidney disease

Physiological Reports, 2023
Patients with chronic kidney disease (CKD) are more likely to die of cardiovascular diseases, including cerebrovascular disease, than to progress to end‐stage kidney disease.

A high salt meal does not impair cerebrovascular reactivity in healthy young adults

Physiological Reports, 2020
A high sodium (Na+) meal impairs peripheral vascular function. In rodents, chronic high dietary Na+ impairs cerebral vascular function, and in humans, habitual high dietary Na+ is associated with increased stroke risk.

Lower neurovascular coupling response despite higher cerebral blood flow at rest in apolipoprotein ɛ4 positive adults.

PLoS ONE
Cerebral blood flow at rest declines with age. However, age-related changes in functional measures of cerebrovascular health including cerebrovascular reactivity and neurovascular coupling are not well understood.
