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

Effects of Prone Position and Positive End-Expiratory Pressure on Noninvasive Estimators of ICP: A Pilot Study. [PDF]

, 2016
BACKGROUND: Prone positioning and positive end-expiratory pressure can improve pulmonary gas exchange and respiratory mechanics. However, they may be associated with the development of intracranial hypertension.

Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

Experimental Physiology, EarlyView.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

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 ...

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Quantification of the cerebral pressure–flow relationship directional sensitivity: Reliability of shorter repeated squat–stand durations

Experimental Physiology, EarlyView.
Abstract The magnitude of changes in middle cerebral artery mean blood velocity (MCAv) is attenuated when mean arterial pressure (MAP) increases compared with when MAP decreases. This directional sensitivity has been characterized using a time‐corrected ratio calculated on MCAv and MAP changes induced by repeated squat–stands (RSS) at 0.05 and 0.10 Hz ...
