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

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 ...

Transcranial sonography: practical use in the intensive care unit

Anaesthesiology Intensive Therapy
Brain ultrasonography has emerged as a valuable diagnostic and monitoring tool in intensive care, complementing other point-of-care techniques. Transcranial colour-coded duplex (TCCD) offers a rapid, non-invasive, repeatable, and cost-effective bedside ...

Assessment of the risk of stroke in children with sickle cell anemia using transcranial doppler ultrasound with imaging in Northwestern Nigeria

Nigerian Journal of Paediatrics, 2023
Background: Stroke is a major cause of morbidity and mortality affecting about 10% of patients with sickle cell anemia (SCA). Transcranial Doppler (TCD) ultrasonography helps to identify children with SCA who are at an increased risk for stroke.

Prognosis of acute hemiplegia estimated by transcranial Doppler ultrasonography.

, 1988
Blood velocity in the middle cerebral artery was measured by transcranial Doppler ultrasonography in 15 patients suffering complete hemiplegia of less than 12 hours' duration, presumed due to cerebral ischemia. Among seven patients in whom blood velocity

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.

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 ...

No difference in mean middle cerebral artery blood velocity responses between lower‐ and upper‐body unilateral resistance exercise in untrained individuals

Experimental Physiology, EarlyView.
Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.
