Background: Cerebrovascular hemodynamic impairment has been reported in Alzheimer's
disease (AD). We performed a systematic review and meta-analysis to investigate changes …

BACKGROUND AND PURPOSE: Alteration in cerebrovascular hemodynamics has reported
in both ageing and dementia. However, it is still unclear whether this alteration follows …

BACKGROUND: Multiple lines of evidence suggest that cardiovascular co-morbidities
hasten the onset of Alzheimer's disease (AD) or accelerate its course. METHODS: To …

Abstract Introduction: Transcranial Doppler (TCD) sonography is a noninvasive tool for
measuring cerebrovascular hemodynamics. Studies have reported alterations in …

The intention of this study was to examine the relation of clinical variables and cognitive
dysfunction to cerebrovascular blood flow in a sample of patients with Alzheimer''s disease …

Methods: A total of 68 subjects with amnestic MCI were recruited. Using transcranial Doppler
(TCD) ultrasonography, cerebrovascular reactivity was evaluated with a breath-holding test …

Background Reduced cerebral blood flow (CBF) contributes to the pathophysiology of
Alzheimer's disease (AD). However, it is unclear whether there is a spatial-temporal-specific …

The association of decreased cerebral blood flow with the development of Alzheimer's
disease (AD) has been a recent target of interest. By using neuroimaging techniques …

Cerebral blood flow (CBF) velocity is decreased in patients with Alzheimer's disease. It is
being debated whether this reflects diminished demand because of advanced …

Although transcranial sonography is not yet an established diagnostic modality for dementia
screening or differential diagnosis of Alzheimer's disease (AD) from vascular dementia …
