Objective—Twenty-four–hour ambulatory blood pressure (24-hour ABP) values are considered a powerful predictor of stroke. Silent cerebrovascular lesions are associated with an increased risk of stroke. Because fibrinogen is a major determinant of plasma viscosity, an elevated fibrinogen level might also be associated with stroke risk. We evaluated the association of 24-hour ABP and plasma fibrin...

We studied the relationship of race to incidence of hospitalization for cerebrovascular disease among 74,096 white and 33,041 black persons who took health examinations in a prepaid health care program. Analyses were controlled for age, sex, body mass index, coffee use, smoking, alcohol use, systolic blood pressure, and baseline disease. Blacks were at higher hospitalization risk than whites fo...

In order to find out the relationship between the cerebrovascular acetazolamide reactivity and platelet function in asymptomatic cerebral thrombosis, 10 cases of asymptomatic cerebral infarction and 10 age-matched control subjects were studied. The cerebrovascular acetazolamide reactivity was measured using xenon computed tomography method. As markers of platelet function, the plasma concentrat...

Cerebrovascular dysfunction is rapidly reemerging as a major process of Alzheimer's disease (AD). It is, therefore, crucial to delineate the roles of AD risk factors in cerebrovascular dysfunction. While apolipoprotein E4 ( APOE4), Amyloid-β (Aβ), and peripheral inflammation independently induce cerebrovascular damage, their collective effects remain to be elucidated. The goal of this study was...

OBJECTIVES To assess the association between the occurrence of cerebrovascular disorders and a medication adherence in diabetes mellitus patients. METHODS Medical records from 1,114 new patients with diabetes mellitus were collected and the occurrence of cerebrovascular disorders was observed. Data was gathered from the health examination records of diabetes mellitus patients registered at th...

Alcohol is detrimental to the developing brain and remains the leading cause of mental retardation in developed countries. The mechanism of alcohol brain damage remains elusive. Studies of neurological problems in adults have focused on alcohol's cerebrovascular effects, because alcoholism is a major risk factor for stroke and cerebrovascular injuries. However, few studies have examined similar...

Women are less susceptible to the cerebrovascular complications of hypertension, such as a stroke and vascular dementia. The mechanism of such protection may be related to a reduced vulnerability of women to the cerebrovascular actions of hypertension. To test this hypothesis, we used a model of hypertension based on infusion of angiotensin II (ANG II), an octapeptide that plays a key role in h...

SUMMARY This review article explains the methodology of breath-hold cerebrovascular reactivity mapping, both in terms of acquisition and analysis, and reviews applications of this method to presurgical mapping, particularly with respect to blood oxygen level-dependent fMRI. Its main application in clinical fMRI is for the assessment of neurovascular uncoupling potential. Neurovascular uncouplin...

BACKGROUND AND PURPOSE There are no standard screening guidelines to evaluate blunt cerebrovascular injury in children. The purpose of this retrospective study was to understand the clinical and radiologic risk factors associated with pediatric blunt cerebrovascular injury on CTA of the neck with primary attention to the cervical "seatbelt sign." MATERIALS AND METHODS Radiology reports from 2...

In the present study, the dynamics of the cerebral blood flow (CBF) and ventilatory response to hypercapnia was investigated in a group of patients with cerebrovascular disease and compared to responses measured in a group of normal volunteers. There was a significant correlation between the rapidity of the transient CBF and ventilatory responses and the severity of the cerebrovascular disease....
