Decreased Vasomotor Reactivity in Alzheimer's Disease
BACKGROUND Reduced cerebral blood flow and microvascular abnormalities have been suggested as the vascular pathogenesis of Alzheimer's disease (AD). Transcranial Doppler sonography (TCD) can be used as a noninvasive method for measuring cerebral vasomotor reactivity (VMR) which represent the capability of arterioles to dilate and constrict in order to maintain cerebral blood flow. OBJECTIVE T...
متن کاملEffect of collateral blood flow and cerebral vasomotor reactivity on the outcome of carotid artery occlusion.
BACKGROUND AND PURPOSE Evidence suggests that an alteration in cerebral hemodynamics plays a relevant role in the occurrence of stroke in patients with carotid occlusion. The purpose of the present study was to evaluate the relationships among baseline characteristics, type and number of collateral pathways, cerebral vasomotor reactivity (VMR), and outcome of patients with carotid occlusion. ...
متن کاملRacial heterogeneity in coronary artery vasomotor reactivity: differences between Japanese and Caucasian patients.
Japanese investigators have provided a substantial contribution in the understanding of coronary vasomotor reactivity. On occasions, their findings have been at variance with those undertaken on caucasian patients, raising speculation that vasomotor differences between races may exist. In a comparative review of the published literature, we evaluated the vasoreactive differences among Japanese ...
متن کاملCerebral 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 کاملLeukocyte involvement in vasomotor reactivity of the cerebral vasculature.
A ctivation of leukocytes may play a part in the / \ complex pathophysiological cascade leading to A.V. vasomotor reaction in cerebral arteries. In this issue of Stroke, Akopov et al report changes in endothelium-dependent relaxation by intravascular chemical leukocyte activation involving the cerebral circulation. This interesting study highlights a potential role for leukocytes in the modulat...
