Moderate white matter disease
Characteristic magnetic resonance imaging (MRI) features are used to define SVD, including lacunar infarcts, white matter hyperintensities (WMH), cerebral microbleeds (CMB), enlarged perivascular spaces, and brain atrophy . WMH is further categorized into periventricular and deep (basal ganglion and brain stem regions) . WMH appear to have a vascular pathogenesis and have been shown to confer an increased risk of stroke and cognitive decline.Date de publication : 30 janv.Mild white matter changes may not cause cognitive impairment. The disorder is caused by a lack of oxygen or blood flow to the periventricular area of the brain, which is the area around fluid-filled spaces in the brain called ventricles.White matter changes on MRI were defined as ill-defined hyperintensities greater or equal 5 mm on both T2 and PD/FLAIR images, and on CT as ill-defined and moderately hypodense areas of greater or equal 5 mm.
