Joint Metabonomic and Instrumental Analysis for the Classification of Migraine Patients with 677-MTHFR Mutations [PDF]

open access: yes, 2010
Migraine is a neurological disorder that correlates with an increased risk of cerebrovascular lesions. Genetic mutations of the MTHFR gene are correlated to migraine and to the increased risk of artery pathologies.

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

open access: yes, 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.

Validation of a basic neurosonology laboratory for detecting cervical carotid artery stenosis

open access: yesNeurología (English Edition), 2019
Introduction: Most of the cases of ischaemic stroke in our setting are of atherothrombotic origin. Detecting intracranial and cervical carotid artery stenosis in patients with ischaemic stroke is therefore essential.

Indexing Cerebrovascular Health Using Transcranial Doppler Ultrasound [PDF]

open access: yesUltrasound in Medicine & Biology, 2020
Abstract Transcranial Doppler (TCD) blood flow velocity has been extensively used in biomedical research as it provides a cost-effective and relatively simple approach to assess changes in cerebral blood flow dynamics and track cerebrovascular health status. In this paper, we introduce a new TCD based timing index, TI

Transcranial Doppler ultrasound to assess cerebrovascular reactivity: reliability, reproducibility and effect of posture [PDF]

open access: yes, 2013
Transcranial Doppler ultrasound (TCD) allows measurement of blood flow velocities in the intracranial vessels, and can be used to assess cerebral vasodilator responses to a hypercapnic stimulus. The reliability of this technique has not been established,

Research and Medical Transcranial Doppler System

open access: yesArchives of Acoustics, 2016
A new ultrasound digital transcranial Doppler system (digiTDS) is introduced. The digiTDS enables diagnosis of intracranial vessels which are rather difficult to penetrate for standard systems.

A brain-computer interface based on bilateral transcranial Doppler ultrasound. [PDF]

open access: yesPLoS ONE, 2011
In this study, we investigate the feasibility of a BCI based on transcranial Doppler ultrasound (TCD), a medical imaging technique used to monitor cerebral blood flow velocity.
