Cerebral blood flow in paraplegia

Spinal Cord, 1974
Cerebral blood flow has been measured by a Xenon 133 inhalation technique in patients with chronic high spinal cord injuries and neurological disorders affecting the sympathetic pathways supplying intracranial vessels. These included patients with idiopathic orthostatic hypotension and also patients with a physiologically complete cervical cord ...

Cerebral Blood Flow in Migraine

Headache: The Journal of Head and Face Pain, 1977
SYNOPSIS Cerebral blood flow has seldom been measured during attacks of migraine and cluster headache. The literature is reviewed and five cases studied in our laboratory are described. The results of these studies confirm Wolff's hypothesis that cerebral blood flow is decreased during auras and increased during headaches.

Menstruation and cerebral blood flow

Biological Psychiatry, 1989
Gender differences in cerebral blood flow (CBF) are known to exist, with women reported to have higher rates of blood flow at the hemispheric level and to have higher regional flow values in frontal, temporal, and parietal, but not occipital, areas (Gur et al. 1982; Mathew et al. 1986).

Local cerebral blood flow

Neurology, 1974
An experimental method is described for determining local cerebral blood flow within an area supplied by a major cerebral artery. With the use of anatomic-radiologic correlates, the territories of the anterior and middle cerebral arteries were defined in the rhesus monkey.

Caffeine and Cerebral Blood Flow

British Journal of Psychiatry, 1983
SummaryTwo groups of normal volunteers had regional cerebral blood flow (rCBF) measured, by the133Xenon inhalation technique, before and 30 minutes after 250 mg or 500 mg caffeine given orally. rCBF was measured in a third group of subjects, twice, at a similar interval under identical laboratory conditions.

Cerebral blood flow in the neonate

Pediatric Anesthesia, 2013
SummaryEnsuring adequate oxygenation of the developing brain is the cornerstone of neonatal critical care. Despite decades of clinical research dedicated to this issue of paramount importance, our knowledge and understanding regarding the physiology and pathophysiology of neonatal cerebral blood flow are still rudimentary. This review primarily focuses

Cerebral Blood Flow in Hypertension

Journal of Cardiovascular Pharmacology, 1985
The most important aspect of cerebral blood flow (CBF) in hypertension is the change that occurs in CBF autoregulation: increased cerebrovascular resistance causes the lower and upper limits of CBF autoregulation to be at higher pressure levels. The mechanism seems to be mainly structural thickening and luminal narrowing of cerebral resistance vessels.

Cerebral Blood Flow and Metabolism

2008
To date, regional measurements of cerebral blood flow in humans have not been especially helpful in predicting the outcome of acute brain injury. The recent appearance within the medical environment of biologically significant pharmaceuticals labelled with the positron-emitting isotopes 15O, 13N and 11C has made possible the quantitative regional ...
