Se hela listan på ahajournals.org White Matter Hyperintensities White matter hyperintensities (WMHs) are the bright spots on T2-weighted brain MRI scans. They are very common in elderly individuals, they are more prevalent in people with high blood pressure and other vascular risk factors, and they are associated with poorer cognition. 2016-11-01 · White matter hyperintensities of presumed vascular origin (WMHs), also known as leukoariosis, white matter lesions, or white matter disease (Wardlaw et al., 2013), are common findings in MRI scans and appear hyperintense on T2-weighted, fluid attenuated inversion recovery (FLAIR), and proton density-weighted images.

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.

Transient lesions in the white matter (leukoencephalopathy) due to chemotherapy are well-documented in ALL survivors (Bhojwani et al., 2014; Reddick, Glass,

Behavioral The presence of a few hyperintense punctate foci in the cerebral white matter at MRI is a very common finding that can be regarded as insignificant in most of the White matter disease is a broad term encompassing a range of problems affecting the white matter of the brain. White matter consists of many nerves important Why are areas of gray matter deep in the brain called nuclei? The axons in the white matter send the information to dendrites and soma of the cortical neurons, You should evaluate different spaces for white matter abnormality, including the The locations of the lesions can provide a clue as to whether white matter lesions are with loss of internal architecture and abnormal T2/FLAIR hype Fig. 1 Examples of different severity of a D-WMH and b PVH are shown - " Periventricular white matter hyperintensities increase the likelihood of progression from T2 weighted images in medical MRI scans usually focus on white matter.

2010-07-26 · White matter hyperintensities were significantly associated with an increased risk of death both in the general population and in high risk populations with a history of stroke, depression, or minor neurological symptoms. This association could be mediated by an increased risk of stroke and dementia.

Statistical analysis The characteristics of our study were summarized using means and standard deviations (SD) for continuous variables and frequencies and percentages (%) for categorical variables.

3. CNS white matter anomalies not consistent regions, and it was found that anterior white matter hyperintensity was related to the initial factor in LF. In Study III, substantial differences were found between LF callosum abnormalities (n = 20), reduced volume of the white matter (WM) (n = 12), ventricular dilatation (n = 9), abnormal increased hyperintensities on Liknande ord.

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].

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.

However, age may modify the associations between hypertension and WMH, and their links to cognitive impairment. 2021-03-25 · White matter hyperintensity volume, type and shape correlated with an increased risk for mortality and ischemic stroke among patients with manifest arterial disease, according to findings from the 2013-05-09 · Background 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 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.
