Association Between Gas‐Free Cerebrovascular Reactivity (CVR) and Cognitive Function in Older Adults With a High Risk for Vascular Dementia

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Vascular cognitive impairment and dementia (VCID) is the second leading cause of dementia. Cerebrovascular reactivity (CVR) is a promising biomarker for VCID. However, CVR is not commonly measured in clinical practice due to logistical difficulties in applying a hypercapnia challenge during MR imaging. Purpose To investigate whether

Therapeutic hypercapnia. Review

Ageing & Longevity, 2022
In recent years, interest in hypercapnia and its practical applications has grown significantly. An analysis of literature data shows a wide range of systemic and local applications. Due to its powerful effect on blood circulation, vascular elasticity, activation of angiogenesis, and inhibition of pro-inflammatory factors, hypercapnia is already used ...
