There are cognitive changes in primary hyperparathyroidism (PHPT) that improve with parathyroidectomy, but the mechanism of cognitive dysfunction has not been delineated. We assessed if cerebrovascular function is impaired in PHPT, improves post-parathyroidectomy and is associated with PTH level and cognitive dysfunction. This is an observational s...

Background Decreased endothelial function (EF) may be a prognostic marker for stroke. Measuring pharmacological effects on EF may be of interest in the development of personalized medicine for stroke prevention. In this study, we assessed the reliability of repeated EF measurements using a pulse amplitude tonometry technology in acute stroke patien...

A competent cerebrovascular regulation maintains an adequate cerebral blood flow by 3 major mechanisms: cerebral autoregulation (CA), vasomotor reactivity (VMR), namely to CO2, and neurovascular coupling (NVC). However, most studies generalize their results based on a response to a single parameter. Using a full battery of neurovascular stress test...

We assessed reactivity of cerebral vessels on hypercapnia in patients with carotid occlusive disease. The effects of vascular risk factors on carotid atherosclerosis and vasomotor reactivity (VMR) of cerebral arterioles were also examined. Patients (n = 50) with carotid stenosis (≥30% in 1 or both sides) were included; 30 patients acted as controls...

Compartmental and data-based modeling of cerebral hemodynamics are alternative approaches that utilize distinct model forms and have been employed in the quantitative study of cerebral hemodynamics. This paper examines the relation between a compartmental equivalent-circuit and a data-based input-output model of dynamic cerebral autoregulation (DCA...

This study indicates that the VMR of women with stable SLE is not significantly different from the age- and sex-matched normal population. However, further investigations on patients with longer SLE duration and more neuropsychological abnormality rates are suggested.

BackgroundThe aim of the present study was to assess the regional variation in cerebral perfusion, vasomotor reactivity (VMR) and the role of cerebral collaterals in patients with symptomatic internal carotid artery (ICA).MethodsSeventeen functionally independent patients (60±9 years, mean±SD) with a unilateral symptomatic internal carotid artery o...
