Cerebrovascular reactivity in multiple sclerosis patients
Multiple Sclerosis Journal, 2007 A close relationship between multiple sclerosis (MS) lesions and the cerebral vasculature has long been recognised. Some studies have suggested that vascular endothelial cell activation might be an early event in the evolution of MS, and demyelisation may have an ischemic basis in this condition.

Cerebrovascular Reactivity in Migraine With and Without Aura
Headache: The Journal of Head and Face Pain, 1996 Abnormal cerebrovascular regulation has been implicated in the pathogenesis of migraine. Our aim in this study was to evaluate cerebrovascular reactivity to different stimulations in migraine with and without aura. Using bilateral transcranial Doppler, the changes of flow velocity during hypercapnia and mental and motor activity were measured in the ...

Cerebrovascular Reactivity and Concussion
Neuroimaging Clinics of North America, 2023Cerebrovascular reactivity (CVR) reflects the change in cerebral blood flow in response to vasodilatory stimuli enabling assessment of the health of the cerebral vasculature. Recent advances in the quantitative delivery of CO2 stimuli with computer-controlled sequential gas delivery have enabled mapping of the speed and magnitude of response to flow ...

Older Adults With Higher Blood Pressure Variability Exhibit Cerebrovascular Reactivity Deficits [PDF]
American Journal of Hypertension, 2023 BACKGROUND: Elevated blood pressure (BP) variability is predictive of increased risk for stroke, cerebrovascular disease, and other vascular brain injuries, independent of traditionally studied average BP levels.

Circadian cerebrovascular reactivity to CO2
Respiratory Physiology & Neurobiology, 2014Cerebrovascular reactivity (CVR) assesses the ability of the cerebral vasculature to adjust cerebral blood flow in response to changes in arterial carbon dioxide (CO2), and is used as an indicator of cerebrovascular health. A common method of estimating CVR is to measure the increase in blood flow velocity of the middle cerebral artery (MCAv), using ...

Cerebrovascular Autoregulation and Monitoring of Cerebrovascular Reactivity
2013Cerebrovascular autoregulation and reactivity are two important processes which maintain CBF at metabolically appropriate levels in response to fluctuations in cerebral perfusion pressure. Additionally, intact vascular reactivity protects the cerebral capillary bed against excessive hydrostatic pressures that may precipitate vasogenic oedema.

Cerebrovascular reactivity: rat studies in rheoencephalography
Physiological Measurement, 2004Here we describe a correlative study of cerebral blood flow (CBF) using global, local CBF and carotid flow measurements. The primary objective of this study was to establish a relationship between REG and CBF autoregulation. Rheoencephalography (REG), a rarely used method to measure CBF, is a potential tool of non-invasive continuous life sign ...

Assessment of Cerebrovascular Reactivity
2018Such factors as cerebrovascular reserve, condition of cardiac hemodynamics, systemic blood pressure, and rheological parameters of blood have a big influence on cerebral circulation.
