Metabolic syndrome and cerebral vasomotor reactivity

European Journal of Neurology, 2010
Background and purpose:  Metabolic syndrome has been proposed as a risk factor for stroke and transient ischaemic attack. One pathophysiological mechanism could be impairment of endothelial function. Thus, we hypothesized that cerebral vasomotor reactivity would be decreased in patients with metabolic syndrome, compared to patients without metabolic ...

Cerebral Vasomotor Reactivity and Risk of Mortality [PDF]

Stroke, 2014
Background and Purpose— Accumulating vascular pathology in cerebral arteries leads to impaired cerebral vasomotor reactivity. In turn, impaired cerebral vasomotor reactivity is a risk factor for stroke in clinical populations. It remains unclear whether impaired cerebral vasomotor reactivity also reflects more systemic vascular

Cerebral vasomotor reactivity in patients with arterial hypertension and cognitive impairment [PDF]

Romanian Journal of Neurology, 2016
Objectives. The aim of our study is to determine whether cerebral vasomotor reactivity is impaired in patients with arterial hypertension and cognitive impairment and how this hemodynamic parameter is associated with different functions of cognition ...

Intradermal tests with vasomotor agents in chronic non(infectious rhinitis [PDF]

Vojnosanitetski Pregled, 2002
The aim of this prospective study was to examine the skin reactivity to four vasomotor agents in chronic, non-infectious rhinitis patients, and to determine whether non-allergic rhinitis (NAR) patients differ from allergic rhinitis (AR) patients. Seventy

Cortical Neuromodulation Modifies Cerebral Vasomotor Reactivity [PDF]

Stroke, 2010
Background and Purpose— Cerebral vasomotor reactivity (VMR) is a capability of cerebral vessels to dilate in response to hypercapnia. Transcranial direct current stimulation (tDCS) effects on cerebral hemodynamics have been poorly studied.

Cerebral hemodynamic changes to transcranial Doppler sonography in celiac disease: A pilot study

Frontiers in Human Neuroscience, 2022
BackgroundSonographic mesenteric pattern in celiac disease (CD) suggests a hyperdynamic circulation. Despite the well-known CD-related neurological involvement, no study has systematically explored the cerebral hemodynamics to transcranial Doppler ...

Decreased Vasomotor Reactivity in Alzheimer's Disease [PDF]

Journal of Clinical Neurology, 2007
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 ...
