White matter hyperintensities

White matter hyperintensities (WMHs) are lesions in the brain that show up as areas of increased brightness when visualised by T2-weighted magnetic resonance imaging (MRI). WMH's are also referred to as Leukoaraiosis and are often found in CT or MRI's of older patients 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 spots may be described in your MRI report as high signal intensity areas, white matter hyperintensities, leukoaraiosis (often used if spots are felt to be caused by decreased blood flow), or nonspecific white matter changes. They are usually found in the brain's white matter, typically near the ventricles Conclusion White matter hyperintensities predict an increased risk of stroke, dementia, and death. Therefore white matter hyperintensities indicate an increased risk of cerebrovascular events when identified as part of diagnostic investigations, and support their use as an intermediate marker in a research setting White matter hyperintensities (WMHs) are frequently seen on brain MRI in older people, and are thought to result from chronic ischaemia associated with cerebral small vessel 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 White matter hyperintensities (WMH) and increased signals on fluid‐attenuated inversion recovery (FLAIR) brain image sequences are commonly present in patients with PD, and the severity and location of WMH can be easily evaluated using the Fazekas visual scale. 6 However, there are a limited number of studies study the association between apathy and WMH in PD patients

The clinical importance of white matter hyperintensities

  1. White matter hyperintensities is a term used to describe spots in the brain that show up on magnetic resonance imaging (MRIs) as bright white areas. 4  According to Charles DeCarli, the director of UC Davis Alzheimer's Disease Center, these areas may indicate some type of injury to the brain, perhaps due to decreased blood flow in that area
  2. Hypertension and cerebral small vessel disease (SVD), particularly white matter lesions or white matter hyperintensities (WMH) on cranial magnetic resonance imaging (MRI), are closely linked to cognitive decline [ 1, 2 ], and have close mutual links [ 3 ]
  3. white matter hyperintensities at earlier stages, and changes in normal-appearing white matter that indicate tissue pathology, less marked than those found in WMH. These pre-visible changes show that altered interstitial fluid mobility and water content, which may be reversible, probably predate demye

MATERIALS AND METHODS: From a group of patients participating in a double-blind placebo-controlled multicenter study on the effect of pravastatin (PROSPER), we selected 56 subjects with WMH Soon after the introduction of MR imaging, periventricular hyperintensities started to vex the scientific community. 1 While they may be a consequence of distinct disorders such as multiple sclerosis causing focal periventricular lesions or increased intraventricular pressure giving rise to extending hyperintense rims around the lateral ventricles, most periventricular white matter. White matter hyperintensities (WMH) lesions on T2/FLAIR brain MRI are frequently seen in healthy elderly people. 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 and deep.

White matter hyperintensities, either unilateral or bilateral, are detected as high-signal-intensity punctate foci on T2WI and FLAIR images most commonly in the white matter of the centrum semiovale, contrary to small high-signal-intensity lesions seen at deep white matter of ischemic brain changes Leukoaraiosis, also known as white matter hyperintensities, is strongly linked to the cerebral small vessel disease, which increases the risk of stroke, cognitive decline, dementia, and infarct progression [1, 2] Article discussed: White matter hyperintensities: use of aortic arch pulse wave velocity to predict volume independent of other cardiovascular risk factors..

White Matter Hyperintensities at the age of 30-40: The white matter disease is common in the brains of healthy individuals in their 60s and rarely seen at the age of thirty and forty. Interaction with environmental factors, appear to be important. There is a slight factor of white matter disease in women more than men which are not understood Deterioration of the white matter happens with ageing and can be seen on brain scans as white matter lesions (abnormal areas). These appear as bright areas or white matter 'hyperintensities' on some brain MRI scans. White matter lesions are one of the most common incidental findings on brain scans White matter hyperintensities are thought to be caused by small vessel infarcts (restriction in blood flow) in the white matter and ultimately result in impairment of brain functions, such as cognition, balance and gait, that depend on complicated interactions between regions

Here, we investigate the impact of the presence of white matter hyperintensities (WMHs) on FreeSurfer gray matter (GM) structure volumes and its possible bias on functional relationships. T1‐weighted images from 1,077 participants (4,321 timepoints) from the Alzheimer's Disease Neuroimaging Initiative were processed with FreeSurfer version 6.0.0 White matter hyperintensities (WMH) primarily affect the risk of progression to mild cognitive impairment (MCI) when cerebrospinal fluid (CSF) measures of neurodegeneration or neuronal injury are low. But CSF biomarkers of amyloid, phosphorylated-tau, and WMH appear to have an independent effect on the risk of progression to MCI Magnetic resonance imaging (MRI) T2-weighted white matter hyperintensities (WMHs) are commonly observed in aging brains, grow over time 1 -4 and are associated with cognitive decline, 5 -10 motor impairment, 8 stroke, 6,11,12 and mortality. 6 White matter hyperintensity (WMH) is characterized pathologically by demyelination, axonal loss, and rarefaction, 13 often attributed to vascular.

white matter hyperintensities in brain magnetic resonance imaging Mohamed Negm1*, Ahmed Mohamed Housseini2, Mohamed Abdelfatah1 and Alshimaa Asran3 Abstract Background: Migraine is a common disorder in general population. Presence of white matter hyperintensities (WMHs) in brain MRI of migraine patients was not studied clearly Aging is associated with increased white matter hyperintensities (WMHs) and with the alterations of alpha oscillations (7-13 Hz). However, a crucial question remains, whether changes in alpha oscillations relate to aging per se or whether this relationship is mediated by age-related neuropathology like WMHs. Using a large cohort of cognitively healthy older adults (N=907, 60-80 years), we. White matter hyperintensities (WMH) are typically segmented using MRI because WMH are hardly visible on 18F-FDG PET/CT. This retrospective study was conducted to segment WMH and estimate their volumes from 18F-FDG PET with a generative adversarial network (WhyperGAN). We selected patients whose interval between MRI and FDG PET/CT scans was within 3 months, from January 2017 to December 2018. On magnetic resonance imaging (MRI), subcortical white matter hyperintensities and lacunar infarcts are visualized. It is unknown whether a decrease in cerebral blood flow or cerebrovascular reactivity is primarily responsible for the development of white matter hyperintensities and lacunar infarcts Background. White matter hyperintensities (WMH) on magnetic resonance imaging may influence clinical presentation in patients with Parkinson's disease (PD), although their significance and pathophysiological origins remain unresolved
