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, 2023
Cerebrovascular 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 ...

Circadian cerebrovascular reactivity to CO2

Respiratory Physiology & Neurobiology, 2014
Cerebrovascular 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 ...

The Variability of Cerebrovascular Reactivity with Posture and Time

Journal of Neurosurgical Anesthesiology, 1996
Transcranial Doppler (TCD) ultrasonography has been used in a variety of clinical contexts to assess cerebrovascular reserve by measuring carbon dioxide reactivity. Reproducibility with time and altered position of the patient is examined in the present study. Carbon dioxide reactivity was determined in 10 healthy volunteers using TCD.
