Cerebral vasomotor reactivity in epilepsy patients
Journal of Neurology, 2009Vasomotor reactivity, which can be defined as the cerebral vasculature response to hypoxia, is not well known in epilepsy patients. We aimed to evaluate cerebrovascular reserve in idiopathic generalized epilepsy patients using transcranial Doppler ultrasonography (TCD). The study included 20 patients and 20 healthy volunteers. Diagnosis of epilepsy was

Vasomotor Reactivity in Dupuytren's Contracture
Journal of Applied Physiology, 1957Fifteen patients with Dupuytren's contracture were studied with a photoelectric plethysmograph. Ten individuals with normal hands served as controls. Plethysmograms were recorded as follows: a ) normal hands; b ) uninvolved hand of patient with Dupuytren's contracture; c ) hand of patient with early Dupuytren's contracture; d ) hand of patient with ...

Cerebral vasomotor reactivity in neurodegenerative diseases
Neurologia i Neurochirurgia Polska, 2016Small-caliber cerebral vessels change their diameters in response to alterations of key metabolite concentrations such as carbon dioxide or oxygen. This phenomenon, termed the cerebral vasomotor reactivity (CVMR), is the basis for blood flow regulation in the brain in accordance with its metabolic status.

Vasomotor Reactivity in Premature Neonates at Term
Neonatology, 2002In order to assess the specific sympathetic reactivity in premature infants at term, we designed a study to evaluate the peripheral vasomotor response of such infants when exposed to auditory challenges. Testing was performed in 29 premature neonates at term in both quiet and active sleep during a morning session.

Cerebral Vasomotor Reactivity in Amnestic Mild Cognitive Impairment
Journal of Alzheimer's Disease, 2020Background: Cerebral blood flow (CBF) is sensitive to changes in arterial CO2, referred to as cerebral vasomotor reactivity (CVMR). Whether CVMR is altered in patients with amnestic mild cognitive impairment (aMCI), a prodromal stage of Alzheimer disease (AD), is unclear.

Cerebral vasomotor reactivity in reversible cerebral vasoconstriction syndrome
Cephalalgia, 2016BackgroundAltered cerebrovascular tone is implicated in reversible cerebral vasoconstriction syndrome (RCVS). We evaluated vasomotor reactivity using bedside transcranial Doppler in RCVS patients.MethodsIn this retrospective case-control study, middle cerebral artery (MCA) blood flow velocities were compared at rest and in response to breath-hold in ...

Sweating Function and Retinal Vasomotor Reactivity in Migraine
Cephalalgia, 1989Sweating function and retinal arterial reactivity in patients with migraine were examined during headache-free intervals. The sweat glands were stimulated by intradermal injection of pilocarpine hydrochloride, and molds of sweat droplets were obtained using Silastic.

[Cerebral vasomotor reactivity: functional tests].
La Clinica terapeutica, 1996The evaluation of cerebrovascular reactivity provides quantitative and qualitative information about cerebral hemodynamics in patients with external and internal cerebrovascular disease. Cerebrovascular reactivity is defined as the capability of the intracerebral arterioles to dilate; it may be diminished or exhausted in patients with insufficiently ...

Cerebral Autoregulation and Vasomotor Reactivity
2006Various aspects of the cerebral blood-flow regulation can be assessed by transcranial Doppler (TCD). This chapter describes and discusses the approaches that have been reported in the literature. The steady-state characteristics of the cerebral autoregulation can be determined by changing the blood pressure level, and calculating the response of the ...

High-Dose Atorvastatin Enhances Impaired Cerebral Vasomotor Reactivity
Journal of Stroke and Cerebrovascular Diseases, 2012The influence of statin therapy on cerebral vasomotor function has not been fully characterized. We report the effects of high-dose atorvastatin therapy on cerebral vasomotor reactivity (VMR) in patients with controlled hypertension and dyslipidemia. We prospectively enrolled 36 patients with controlled hypertension and a low-density lipoprotein (LDL ...
