Evaluation of vasomotor response in ophthalmic migraine patients [PDF]

Romanian Journal of Neurology, 2016
Introduction. Hemodynamic changes of the cerebral arteries in ophthalmic migraine may be an important pathophysiological mechanism of the disease. The nitric oxide (NO) synthesis plays a significant role in hemodynamic changes due to vasodilatation ...

Transcranial Doppler ultrasonography predicts cardiovascular events after TIA

BMC Medical Imaging, 2009
Background Transient ischemic attack (TIA) patients are at high vascular risk. We assessed the value of extracranial (ECD) and transcranial (TCD) Doppler and duplex ultrasonography to predict clinical outcome after TIA.

Diagnostic value of transcranial ultrasonography for selecting subjects with large vessel occlusion: a systematic review

The Ultrasound Journal, 2019
Introduction A number of pre-hospital clinical assessment tools have been developed to triage subjects with acute stroke due to large vessel occlusion (LVO) to a specialised endovascular centre, but their false negative rates remain high leading to ...

Gender and rapid alterations of hemispheric dominance during planning [PDF]

, 2012
BACKGROUND: Mental planning and carrying out a plan provoke specific cerebral hemodynamic responses. Gender aspects of hemispheric laterality using rapid cerebral hemodynamics have not been reported.

Role of transcranial Doppler ultrasonography in stroke [PDF]

Postgraduate Medical Journal, 2007
AbstractTranscranial Doppler sonongraphy is a non-invasive, non-ionising, inexpensive, portable and safe technique that uses a pulsed Doppler transducer for assessment of intracerebral blood flow. This article deals with the principles and technique of transcranial Doppler sonography.

The implementation of transcranial Doppler ultrasonography for preclinical study of migraine [PDF]

, 2022
Transcranial Doppler ultrasonography is used to study intracranial blood flow changes associated with migraine in humans, but whether this method is helpful in preclinical settings is yet unknown.

The effects of chronic trans-resveratrol supplementation on aspects of cognitive function, mood, sleep, health and cerebral blood flow in healthy, young humans [PDF]

, 2015
Single doses of resveratrol have previously been shown to increase cerebral blood flow (CBF) with no clear effect on cognitive function or mood in healthy adults.

HOPE Kids 2: Phase 3, Randomized Trial of Voxelotor in Children With SCD and Conditional Cerebral Blood Flow Velocities

American Journal of Hematology, EarlyView.
ABSTRACT Children with SCD have elevated stroke risk, correlated with cerebral blood flow velocity (CBFV). HOPE Kids 2 was a phase 3, multicenter, double‐blind, placebo‐controlled trial evaluating the effect of voxelotor on CBFV. Participants aged 2 to < 15 years with SCD (HbSS/HbSβ0) and conditional CBFV (170 to < 200 cm/s) were randomized 1:1 to ...
