A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

Experimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Sex differences in dynamic cerebral autoregulation responses to resistance and endurance training in humans

Experimental Physiology, EarlyView.
Abstract Exercise maintains brain health and reduces the risk of cerebrovascular diseases, such as stroke and dementia. The benefits of different ‘modalities’ of exercise on male and female cerebral autoregulation are unclear. In this study, we compared adaptations in dynamic cerebral autoregulation (dCA) during spontaneous and forced oscillations in ...

Transcranial Doppler ultrasound evaluation of vascular recanalization following tissue plasminogen activator intravenous thrombolysis in acute middle cerebral artery occlusion: A case report and literature review

SAGE Open Medical Case Reports
Acute cerebral infarction, or stroke, is one of the leading causes of death and disability among adults worldwide, and the key to its treatment is achieving early recanalization of occluded blood vessels, methods for which include intravenous ...

Transcranial color-coded sonography in the management of patients with cervical and intracranial arterial stenosis [PDF]

, 2014
peer reviewedLe progrès technique en imagerie a permis le développement de l’écho-Doppler transcrânien en mode duplex ou triplex. A côté des autres techniques de neuro-imagerie, son intérêt dans la pathologie vasculaire cérébrale va grandissant.

CARE‐ing for concussions: Development of the Calgary Adapted aRm Ergometer (CARE) exertion test: A physiological alternative to the Calgary Concussion Cycle Test

Experimental Physiology, EarlyView.
Abstract Aerobic exercise testing helps facilitate recovery post‐concussion. Current protocols (Calgary Concussion Cycling Test: CCCT) are inaccessible for athletes with lower‐body impairments (i.e. Para athletes). This study compared physiological parameters for a novel arm crank test, the Calgary Adapted aRm Ergometer (CARE) test, with the CCCT ...

Cerebrovascular regulation during heat stress

Experimental Physiology, EarlyView.
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.

Intracranial hypertension influence on the cerebral blood flow in children with serous meningitis

Журнал инфектологии, 2014
Transcranial Doppler sonography was performed in 120 children with serous meningitis with various degrees of intracranial hypertension. Cerebral blood flow disturbances – decreased dilatation reserve and mean blood flow velocity in cerebral arteries ...

Comparison of caffeine-induced changes in cerebral blood flow and middle cerebral artery blood velocity shows that caffeine reduces middle cerebral artery diameter [PDF]

, 2004
Changes in cerebral blood flow (CBF) can be assessed directly with xenon clearance (XeC) or indirectly by measuring changes in middle cerebral artery blood velocity (Vmca) with transcranial Doppler (TCD).

Cerebral blood flow regulation, central arterial stiffness and traumatic brain injury: Effects of aerobic exercise training

Experimental Physiology, EarlyView.
Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...
