Dynamic cerebral autoregulation (CA) is the transient response of cerebral blood flow (CBF)
to rapid blood pressure changes: it improves in hypocapnia and becomes impaired during …

Essential hypertension has devastating effects on the brain, being the major cause of stroke
and a leading cause of dementia. Hypertension alters the structure of cerebral blood vessels …

Maintenance of brain function depends on a constant blood supply. Deficits in cerebral
blood flow are linked to cognitive decline, and they have detrimental effects on the outcome …

BACKGROUND: The cerebral perfusion pressure that denotes the lower limit of cerebral
blood flow autoregulation (LLA) is generally considered to be equivalent for reductions in …

Background and Purpose—Assessment of cerebral autoregulation has been traditionally
performed with static changes in arterial blood pressure. Newer dynamic methods require …

There are occasionally intraoperative circumstances in which reduction of mean arterial
pressure (MAP) to levels well below those that occur in nonanesthetized adults is necessary …

Significance: The brain has high energetic requirements and is therefore highly dependent
on adequate cerebral blood supply. To compensate for dangerous fluctuations in cerebral …

Background: Dynamic cerebral autoregulation (DCA) is the continuous counterregulation of
cerebral blood flow to fluctuations in blood pressure. DCA can become impaired after acute …

The aim of this study was to determine whether lower body negative pressure (LBNP),
combined with noninvasive methods of assessing changes in systemic and cerebral …

Cerebral blood flow regulation is based on a variety of different mechanisms, of which the
relative regulatory role remains largely unknown. The cerebral regulatory system expresses …
