Transcranial sonography in Parkinson’s disease [PDF]

Einstein (São Paulo), 2012
Transcranial sonography has become a useful tool in the differentialdiagnosis of parkinsonian syndromes. This is a non-invasive, low costprocedure. The main finding on transcranial sonography in patientswith idiopathic Parkinson’s disease is an increased

Migraine with aura and TCD bubble-test: The significance of positive result [PDF]

Vojnosanitetski Pregled, 2015
Background/Aim. The association between the right-to left shunt (RLS) and migraine with aura (MA) has been proven so far. The aim of this study was to determine if the presence of RLS detected as a result of transcranial doppler (TCD) bubble ...

Optimizing cerebrovascular endothelial health through shear stress modulation

Experimental Physiology, EarlyView.
Abstract The endothelium plays a pivotal role in regulating cerebrovascular blood flow, and its dysfunction increases the risk of cerebrovascular disease. Endothelial shear stress, a primary mechanical stimulus for endothelial nitric oxide production, is a key modulator of vascular adaptation.

Time‐course analysis of cerebral circulation and cardiorespiratory responses to acute central blood volume reduction in healthy young males

Experimental Physiology, EarlyView.
Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...

Role of transcranial Doppler ultrasonography in acute stroke

Annals of Indian Academy of Neurology, 2008
Background: Transcranial Doppler (TCD) ultrasonography is the only noninvasive examination that provides a reliable evaluation of intracranial blood flow patterns in real-time, adding physiological information to the anatomical information obtained from

Different locations but common associations in subcortical hypodensities of presumed vascular origin: cross-sectional study on clinical and neurosonologic correlates [PDF]

, 2014
BACKGROUND: Subcortical hypodensities of presumed vascular etiology (SHPVO) are a clinical, radiological and neuropathological syndrome with a still largely unexplained pathophysiology.

Transcranial Doppler ultrasonography in anaesthesia and intensive care [PDF]

British Journal of Anaesthesia, 2004
Transcranial Doppler ultrasonography (TCD) was introduced in 1982 by Aaslid and colleagues 5 as a non-invasive technique for monitoring blood flow velocity (FV) in the basal cerebral arteries. It is now increasingly being used in anaesthesia and intensive care for research as well as in clinical practice.

Cerebral haemodynamic responses to inspiratory muscle work

Experimental Physiology, EarlyView.
Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.
