Blood pressure, internal carotid artery flow parameters, and age-related white matter hyperintensities.
White matter hyperintensities (WMH) are associated with hypertension. We examined interactions among blood pressure (BP), internal carotid artery (ICA) flow velocity parameters, and WMH. We obtained BP measurements from 694 community-dwelling subjects at mean ages 69.6 (±0.8) years and again at 72.6 (±0.7) years, plus brain MRI and ICA ultrasound at age 73±1 years. Diastolic and mean BP decreas...
متن کاملAge-Related Modifications of Diffusion Tensor Imaging Parameters and White Matter Hyperintensities as Inter-Dependent Processes
Microstructural changes of White Matter (WM) associated with aging have been widely described through Diffusion Tensor Imaging (DTI) parameters. In parallel, White Matter Hyperintensities (WMH) as observed on a T2-weighted MRI are extremely common in older individuals. However, few studies have investigated both phenomena conjointly. The present study investigates aging effects on DTI parameter...
متن کاملCerebral blood flow and internal carotid artery flow during carotid surgery.
Abxtract: Cerebral Blood Flow and Internal Carotid A rtery Flow During Carotid Surgery • In a series of 17 patients operated on for stenosis of the internal carotid artery, measurement of the blood flow in the internal carotid artery by a squarewave electromagnetic flowmeter was performed simultaneously with measurement of the regional cerebral blood flow (rCBF) by the Xenon injection technique...
متن کاملAge-related changes in carotid artery flow and pressure pulses: possible implications for cerebral microvascular disease.
BACKGROUND AND PURPOSE We sought to establish the relation between the pulsatile components of pressure and flow waveforms in the carotid artery and their change with age. METHODS Distention (pressure) and axial flow velocity waveforms were recorded noninvasively and simultaneously from the common carotid artery of 56 healthy subjects aged 20 to 72 years. RESULTS There was a close relation ...
متن کاملHigh prevalence of white matter hyperintensities in normal aging: relation to blood pressure and cognition.
The occurrence of cerebral white matter hyperintensities (WMHs), and their associations with blood pressure, episodic memory, and other cognitive tasks, were examined in a population-based sample of 123 individuals between 64 and 74 years old. Magnetic Resonance Imaging (MRI) detected subcortical and periventricular hyperintensities in 90% and 67% of the cases, respectively. Subcortical WMHs we...
