Cerebral Autoregulation Following Traumatic Brain Injury
Cerebral pressure autoregulation (AR) is a complex intrinsic control mechanism which maintains a constant cerebral blood flow (CBF). This mechanism was found to be impaired after traumatic brain injury (TBI) and was suggested to be associated with variety of cerebrovacular abnormalities found after injury, as disturb AR might increases the vulnerability of the brain to secondary ischemic insult...
متن کاملDynamic cerebral autoregulation is unaffected by aging.
BACKGROUND AND PURPOSE Normal aging is associated with marked changes in the cardiovascular and cerebrovascular systems. Although cerebral autoregulation (CA) is impaired in certain disease states, the effect of age per se on dynamic CA in humans is unknown and the focus of this study. METHODS Twenty-seven young subjects (/=55 years), matched for sex and s...
متن کاملClinical Relevance of Cerebral Autoregulation following Spontaneous Intracerebral Haemorrhage
Hypertensive intracranial haemorrhage is a common neurological emergency in clinical practice. The presence of an intracranial lesion of expansive focal nature can compress vascular structures and cause ischaemic effects. It is very common for these patients to have hypertensive peaks at admission, which may progress to rebleeding and neurological worsening. The safety of blood pressure reducti...
متن کاملAutoregulation of Cerebral Circulation
Autoregulation of cerebral circulation is the mechanism by which the cerebral blood flow (CBF) is maintained constant between large limits of arterial pressure. Autoregulation appears only between certain pressure limits. The specialized literature presents 2 possible mechanisms of autoregulation: myogenic reaction and metabolic regulation. Sympathetic nervous system stimulation and the antagon...
متن کاملWhy is the neural control of cerebral autoregulation so controversial?
Cerebral autoregulation refers to the mechanisms that act to keep cerebral blood flow (CBF) constant during changes in blood pressure. The mechanisms of cerebral autoregulation, especially in humans, are poorly understood but are undoubtedly multifactorial and likely reflect many redundant pathways that potentially differ between species. Whether sympathetic nervous activity influences CBF and/...
