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

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

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

Abstract Background/Aim: The contribution of cerebrovascular dysfunction to the
manifestation of dementia and cognitive decline in late life is gaining increased attention …

Objectives Hemodynamic parameters measured by the Transcranial Doppler Ultrasound
(TCD) are related to cognitive impairment in many cross-sectional studies, but the …

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

Background This study was performed to explore the possible contributions of cerebral
hemodynamic changes to the cognitive impairment in patients with Alzheimer's disease …

Background Potential role of vascular dysfunction has been suggested in the pathogenesis
of Alzheimer's disease (AD). Previous cross-sectional studies have demonstrated relations …

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: An impairment of cerebral microvessels is reported both in normal ageing and
in senescence-associated processes, as well as in Alzheimer's disease (AD) and vascular …
