Pattern of white matter regional cerebral blood flow and autoregulation in normal pressure hydrocephalus.
The mean cerebral blood flow (CBF) has generally been demonstrated to be lower in normal pressure hydrocephalus (NPH) than in normal controls. We investigated the distribution of the regional peri- and paraventricular white matter CBF (WM CBF) in NPH at baseline and during a controlled rise in intracranial pressure (ICP). Twelve patients with idiopathic NPH (mean age 69 years) underwent a CSF i...
متن کاملThe association between blood pressure, hypertension, and cerebral white matter lesions: cardiovascular determinants of dementia study.
Cerebral white matter lesions are frequently observed on magnetic resonance imaging (MRI) scans in elderly people and are associated with stroke and dementia. Elevated blood pressure is presumed one of the main risk factors, although data are almost exclusively derived from cross-sectional studies. We assessed in 10 European cohorts the relation between concurrently and previously measured bloo...
متن کاملRaised intracranial pressure and cerebral blood flow. 4. Intracranial pressure gradients and regional cerebral blood flow.
Intracranial pressure was raised by expansion of a supratentorial subdural ballon in anaesthetized baboons. Pressures were measured at several sites, both supratentorial and infratentorial, and cerebral blood flow was measured in each cerebral hemisphere separately. Pressures recorded from the right and left lateral ventricles corresponded closely throughout. Highly significant correlations wer...
متن کاملCerebral white matter blood flow and arterial blood pressure in preterm infants
UNLABELLED It is generally assumed that one reason why white matter injury is common in preterm infants is the relatively poor vascular supply. AIM To examine whether blood flow to the white matter is relatively more reduced at low blood pressure than is blood flow to the brain as a whole. METHODS Thirteen normoxic preterm infants had blood flow imaging on 16 occasions with single-photon ...
متن کاملDifferent impacts of blood pressure variability on the progression of cerebral microbleeds and white matter lesions.
BACKGROUND AND PURPOSE Cerebral microbleeds (CMB) and white matter lesions (WML) are cerebral small vessel diseases. Hypertension is considered the most important risk factor. Its mechanism is not yet clarified. Our study assessed the association of blood pressure variability (BPV) with CMB and WML progression. METHODS Patients with a history of ischemic stroke within 1 to 6 months were conse...
