The study results suggested that white matter hyperintensities (WMH) “are partly independent of vascular pathology and associated with the neurodegenerative process,” according to the researchers. White matter hyperintensities can be caused by a variety of factors, including ischemia, micro- hemorrhages, gliosis, damage to small blood vessel walls, breaches of the barrier between the cerebrospinal fluid and the brain, or loss and deformation of the myelin sheath. White matter hyperintensities (WMH) is a non-specific term that refers to white matter (WM) signal hyperintensity areas on T2 weighted MRI scans, and correlates with WM rarefaction (leucoaraiosis) as defined on CT scans. 1 The main risk factors associated with development of WMH are older age and blood hypertension. 2 WMH occur both in demented patients and in healthy elderly subjects, and their relevance to cognitive status has not been fully established. White matter hyperintensities (WMH), which are typically detected on fluid-attenuated inversion recovery (FLAIR) brain MRI, are common findings in older adults. WMH are considered a type of sporadic small vessel disease (Wardlaw and Pantoni, 2014).

The aetiology and the pathophysiology of WMH are not yet completely understood. White matter hyperintensities WMHs were present in all 60–64 year old subjects, but their extent and distribution varied considerably (table 2). The mean (SD) volume of WMH was 4.904 (4.976) ml/subject, which represented 0.83% (0.84%) of the total white matter. White matter hyperintensities (WMHs) lacunar infarcts and cerebral microbleeds are well-established features associated with cerebral autosomal dominant arteriopathy with subcortical infarcts and l White matter hyperintensities (WMH) are striking abnormalities that are often found on T2-weighted and fluid-attenuated inversion recovery (FLAIR) images in the elderly. A small right posterior frontal subcortical white matter hyperintensity is present.

The aetiology and the pathophysiology of WMH are not yet completely understood. 2015-02-17 · White matter hyperintensities (WMHs) in the brain are the consequence of cerebral small vessel disease, and can easily be detected on MRI. Over the past three decades, research has shown that the Se hela listan på verywellhealth.com 2020-01-01 · White matter hyperintensities (WMH) are white matter lesions in the brain that appear as high signal intensity regions on T2-weighted MRI. They have a number of possible pathological substrates including blood–brain barrier leakage, hypoperfusion, ischemia/hypoxia, inflammation, neurodegeneration and amyloid angiopathy (Gouw et al., 2011). White matter hyperintensities and imaging patterns of brain ageing in the general population.

White matter hyperintensities can be caused by a variety of factors, including ischemia, micro- hemorrhages, gliosis, damage to small blood vessel walls, breaches of the barrier between the cerebrospinal fluid and the brain, or loss and deformation of the myelin sheath.

Cognitive effects White matter diseases include a wide spectrum of disorders that have in common impairment of normal myelination, either by secondary destruction of previously myelinated structures (demyelinating processes) or by primary abnormalities of myelin formation (dysmyelinating processes). Background: White matter hyperintensities of presumed vascular origin (WMH) are one of the imaging features of cerebral small vessel disease. Controversies persist about the effects of WMH on cognitive dysfunction. White matter hyperintensities (WMHs),detected on T2-weighted Fluid-Attenuated Inversion Recovery (FLAIR) sequence on brain magnetic resonance imaging (MRI),are presumed to be the result of chronic hypoperfusion of the white matter and disruption of the blood–brain barrier, leading to chronic leakage of plasma into the white matter [9,10].

Background: White matter hyperintensities of presumed vascular origin (WMH) are one of the imaging features of cerebral small vessel disease. Controversies persist about the effects of WMH on cognitive dysfunction. White matter hyperintensities proliferate as the brain ages and are associated with increased risk for cognitive decline as well as Alzheimer’s disease and related dementias. As such, white matter hyperintensities have been targeted as a surrogate biomarker in intervention trials with older adults. White matter hyperintensity can occur in various places in the brain.

Scientists in 2011 are honing in on other possible links between white matter hyperintensity and a higher propensity for other human maladies like diabetes, Alzheimer's disease, strokes, multiple sclerosis and heart disease. White matter hyperintensities proliferate as the brain ages and are associated with increased risk for cognitive decline as well as Alzheimer’s disease and related dementias. As such, white matter hyperintensities have been targeted as a surrogate biomarker in intervention trials with older adults.

Whether these radiological lesions correspond to irreversible histological changes is still a matter of debate. We report the radiologic-histopathologic concordance between T2/FLAIR WMHs and neuropathologically confirmed demyelination in the periventricular, perivascular 2020-10-08 · White matter hyperintensities (WMH) are very frequent in older adults and associated with worse cognitive performance. Little is known about the links between WMH and vascular risk factors, cortical β-amyloid (Aβ) load, and cognition in cognitively unimpaired adults across the entire lifespan, especially in young and middle-aged adults. 2018-07-02 · Background White matter hyperintensities (WMHs) are frequently detected in migraine patients.
