Cerebral hypercapnia-induced vasomotor reactivity in migraine with and without aura: a case-control study
Abstract Background: Dysfunction of the autonomic nervous system has long been a subject of considerable debate and a large number of studies have disclosed contradictory results. The aim of this study was to compare cerebral vasomotor reactivity in migraine with aura (MWA) patients with migraine without aura (MWO) ones. Methods: Ten MWA patients (7 females and 3 males mean age: 39.70 years, S...

متن کاملCardiac baroreflex function and dynamic cerebral autoregulation in elderly Masters athletes.
Cerebral blood flow (CBF) is stably maintained through the combined effects of blood pressure (BP) regulation and cerebral autoregulation. Previous studies suggest that aerobic exercise training improves cardiac baroreflex function and beneficially affects BP regulation, but may negatively affect cerebral autoregulation. The purpose of this study was to reveal the impact of lifelong exercise on...
متن کاملCerebral vasomotor reactivity in normotensive and spontaneously hypertensive rats.
Intravenously injected metaraminol induced a larger blood pressure increase in spontaneously hypertensive rats (SHR) than in normotensive controls (NR) when the pressure was raised from the same starting level. Cerebral blood flow (CBF) response in NR was either perfect autoregulation, partial autoregulation or "break-through." When present, the autoregulatory response was very rapid, i.e. the ...
