Relationship between oxygen supply and cerebral blood flow assessed by transcranial Doppler and near-infrared spectroscopy in healthy subjects during breath-holding [PDF]

, 2006
Background Breath – holding (BH) is a suitable method for inducing cerebral vasomotor reactivity (VMR). The assessment of VMR is of clinical importance for the early detection of risk conditions and for the follow-up of disabled patients.

MATHEMATICAL MODELLING OF CIRCULATION IN EXTRACRANIAL BRACHOCEPHALIC ARTERIES AT P RE-OPERATION STAGE IN CAROTID ENDARTERECTOMY

Российский кардиологический журнал, 2017
Aim. Hemodynamic shifts in the brain, developing due to carotid surgery (carotid endarterectomy or stenting) might be the cause of perioperation strokes. Assessment for hemodynamic shifts is important. The aim of current study was to develop methodics of

A precision medicine framework for personalized simulation of hemodynamics in cerebrovascular disease

BioMedical Engineering OnLine, 2021
Background Cerebrovascular disease, in particular stroke, is a major public health challenge. An important biomarker is cerebral hemodynamics. To measure and quantify cerebral hemodynamics, however, only invasive, potentially harmful or time-to-treatment

Lack of effect of pravastatin on cerebral blood flow or parenchymal volume loss in elderly at risk for vascular disease [PDF]

, 2005
<p><b>Background and Purpose:</b> Ageing is associated with a decline in cerebral blood flow. Animal studies have shown that cholesterol-lowering therapy with statins might preserve cerebral blood flow (CBF).

Cerebral Hemodynamics in Patients with Dementia.

Nippon Ronen Igakkai Zasshi. Japanese Journal of Geriatrics, 1996
Cerebral blood flow (CBF) at rest was measured by 123I-IMP SPECT and the standing test was conducted by 99mTc-HMPAO SEPCT in patients with dementia of Alzheimer's type (DAT) and vascular dementia (VD) in order to evaluate cerebral autoregulation and to consider the diagnostic significance of this determination and test.
