Cerebral Vasomotor Reactivity in COVID-19: A Narrative Review [PDF]
Life, 2023 Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects the respiratory system but can also lead to neurological complications. Among COVID-19 patients, the endothelium is considered the Achilles heel.

Cerebral vasomotor reactivity assessment using Transcranial Doppler and MRI with apnea test [PDF]
Brazilian Journal of Medical and Biological Research, 2016 Differently from previous studies that used Transcranial Doppler (TCD) and functional MRI (fMRI) for cerebral vasomotor reactivity (CVR) assessment in patients with carotid stenosis (CS), we assessed CVR using an identical stimulus, the Breath-Holding ...

Impaired Cerebral Vasomotor Reactivity in Alzheimer's Disease. [PDF]
Int J Alzheimers Dis, 2018 Background. Recent studies have shown that cerebral vascularity may be impaired in Alzheimer’s disease. Cerebral vasomotor reactivity could be an important biomarker for this pathology.Aims. The aim of this study was to investigate the alterations in cerebral vascular motor reactivity in Alzheimer’s disease subjects and to associate these changes with ...

Blood pressure is elevated in the absence of resistance artery dysfunction in a mouse model of diet-induced obesity [PDF]
Frontiers in PhysiologyIntroductionHypertension and impaired tissue perfusion are frequent comorbidities in obesity. Since resistance arteries are the primary regulators of peripheral resistance and hence, systemic blood pressure and local blood flow control, we hypothesized ...
