Brain function critically depends on a close matching between metabolic demands,
appropriate delivery of oxygen and nutrients, and removal of cellular waste. This matching …

Cerebral autoregulation is the intrinsic ability of the brain to maintain adequate cerebral
perfusion in the presence of blood pressure changes. A large number of methods to assess …

Cerebral blood flow (CBF) and cerebral autoregulation (CA) are critically important to
maintain proper brain perfusion and supply the brain with the necessary oxygen and energy …

Transcranial Doppler (TCD) is a noninvasive ultrasound (US) study used to measure
cerebral blood flow velocity (CBF‐V) in the major intracranial arteries. It involves use of low …

Cerebrovascular reactivity is the change in cerebral blood flow in response to a vasodilatory
or vasoconstrictive stimulus. Measuring variations of cerebrovascular reactivity between …

Background and Purpose—Cerebral autoregulation may become impaired after stroke. To
provide a review of the nature and extent of any autoregulation impairment after stroke and …

Cerebral autoregulation (CA) refers to the properties of the brain vascular bed to maintain
cerebral perfusion despite changes in blood pressure (BP). Whereas classic studies have …

Non‐technical summary Two mechanisms control brain blood flow by changing blood
vessel diameter: autoregulation maintains flow in the face of perfusion pressure changes …

Loss of cognitive function is one the most devastating manifestations of ageing and vascular
disease. Cognitive decline is rapidly becoming an important cause of disability worldwide …

The relationship between blood pressure (BP) and cognitive outcomes in elderly adults has
implications for global health care. Both hypertension and hypotension affect brain perfusion …
