White matter hyperintensities are common in MRIs of asymptomatic individuals, and their prevalence increases with age from approximately 10% to 20% in those approximately 60 years old to close to 100% in those older than 90 years.
4 mai 2022 · White matter disease is damage to your brain’s white matter caused by reduced blood flow and nutrients. It can affect memory, balance and mobility and is linked to cardiovascular risk factors. Learn how it’s diagnosed and treated.
Over the years it has become increasingly clear that the presence and extent of WMH is a radiographic marker of small cerebral vessel disease and an important predictor of the life-long risk of stroke, cognitive impairment, and functional disability.
This article reviews the clinical and radiological features, investigations and management of patients with white matter abnormalities. It focuses on acquired causes such as multiple sclerosis and small-vessel disease, and genetic causes such as leukodystrophies.
1 ian. 2019 · By mapping motor, sensory, language, and cognitive function, researchers have been able to correlate the studied anatomy through dissections and DTI, with the actual function of the tract. This chapter will provide current data on the localization and function of some of the major WMTs described to date.
26 iul. 2010 · This systematic review of 46 studies, and meta-analysis, provides strong evidence that white matter hyperintensities are an important indicator of future risk of disease, being associated with an increased risk of stroke, cognitive decline (especially in the executive function and processing speed domains), dementia, and death.
19 feb. 2017 · Learn how to visualize and understand the complex network of white matter pathways in the brain using diffusion MRI. This chapter covers the technical aspects of diffusion imaging, the location and function of supratentorial tracts, and the clinical applications of tractography.
