Cerebral vasomotor reactivity at high altitude in humans
Journal of Applied Physiology, 1999The purpose of this study was twofold: 1) to determine whether at high altitude cerebral blood flow (CBF) as assessed during CO2 inhalation and during hyperventilation in subjects with acute mountain sickness (AMS) was different from that in subjects without AMS and 2) to compare the CBF as assessed under similar conditions in Sherpas at high altitude

Does Carotid Endarterectomy Modify Cerebral Vasomotor Reactivity?
Cerebrovascular Diseases, 1997The effects of carotid endarterectomy (CEA) on cerebral hemodynamics in certain groups of patients with severe carotid stenosis still remain unclear. Cerebral vasomotor reactivity (CVR) is an important indicator of intracranial blood supply and cerebral autoregulation.

Cerebral vasomotor reactivity in head-injured patients
Critical Reviews in Neurosurgery, 1998The avoidance of the development of secondary brain damage following head injury is a key point in treating severe brain injury. Recently cerebral perfusionpressure (CPP)-based management, in which volume expansion and vasopressor therapies are often employed to reduce the risk of such secondary brain damage, has improved the long-term neurological ...

Vasomotor reactivity in dementia of alzheimer type
International Journal of Geriatric Psychiatry, 1994AbstractThe objective of this study was to examine the cerebral blood flow and the vasomotor function of CO2‐responsive intracerebral vessels in Alzheimer's disease. Patients met DSM‐III‐R criteria for dementia of Alzheimer type and had neither symptoms nor signs of cardiovascular or cerebrovascular disease.

Reactive oxygen species and the control of vasomotor tone
Current Hypertension Reports, 1999During the past 15 years it has become clear that nitric oxide (NO(*)) released by endothelial cells plays a crucial role in vascular homeostasis. In addition to its role as a vasodilator, NO(*) inhibits platelet aggregation and smooth muscle proliferation and decreases the expression of proinflammatory molecules by the endothelium.

The Feline Carotid Rete: Vasomotor Reactivity of Isolated Arteries
Acta Pharmacologica et Toxicologica, 1983Abstract:Vasomotor responses of arteries from the feline carotid rete were examined using a sensitivein vitrosystem. The vessel segments constricted in response to several vasoactive agents and putative neurotransmitters. Sympathomimetic agents (noradrenaline, adrenaline, oxymetazoline, phenylephrine), 5‐hydroxytryptamine, histamine, angiotensin II ...

Changes in Functional Vasomotor Reactivity in Migraine With Aura
Cephalalgia, 2009Migraine with aura (MA) is associated with cerebral hyper- and hypoperfusion during and after the attacks. Several attempts to estimate individual perfusion changes and asymmetries in patients with MA using transcranial Doppler (TCD) have not been consistent.

Impaired Cerebral Autoregulation and Vasomotor Reactivity in Sporadic Alzheimer’s Disease
Current Alzheimer Research, 2014Understanding the relationship between vascular disease and Alzheimer's disease (AD) will enhance our insight into this disease and pave the way for novel therapeutic research. Cerebrovascular dysfunction, expressed as impaired cerebral autoregulation and cerebral vasomotor reactivity, has been observed in transgenic mouse models for AD. Translation to

Cerebral Vasomotor Reactivity Is Reduced in Patients with Erectile Dysfunction
European Neurology, 2008<i>Backgrounds:</i> Erectile dysfunction (ED) is not only evidence of diffuse atherosclerosis but also an index of early endothelial damage. We investigated cerebrovascular reactivity, expression of early arterial damage, in patients with isolated ED (ED+) and controls (ED–).
