White matter hyperintensities. Abstract 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 Cited by: 3. 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.
One hundred and thirty-seven cognitively. White matter hyperintensities (WMHs) are frequently seen on brain magnetic resonance imaging scans of older people. Usually interpreted clinically as a surrogate for cerebral small vessel disease, WMHs are associated with increased likelihood of cognitive impairment and dementia (including Alzheimer's disease [AD]).Cited by: The presence of white matter hyperintensities may increase the risk that an individual will develop mild cognitive impairment or have declining performances on cognitive tests but may not be enough to facilitate progression from mild cognitive impairment to dementia, the latter being overwhelmingly driven by neurodegenerative lesions.

White matter hyperintensities predicted increases in Clinical Dementia Rating Sum of Boxes (p and Geriatric Depression Scale scores (p = ). Effect sizes were comparable to total brain and hippocampal volume. White matter hyperintensities did not predict diagnostic conversion. From a clinical perspective, severe affectation of white matter could lead to vascular dementia and the presence of these lesions may also contribute to the development of cognitive impairment in other causes of dementia.
16,17 For instance, it has been suggested that the presence of WMH could have an additive deleterious effect to amyloid pathology in Alzheimer’s disease (AD), facilitating the. Aims White matter lesions (WML) are common structural alterations in the white matter of the brain and their prevalence increases with age.
They are associated with cerebral ischaemia and cognitive. White matter lesions (WMLs), which can be studied in vivo by imaging techniques, are related to cognitive impairment.
1, 2 Although other studies observed that severe WML is not necessarily associated with cognitive impairment, 3, 4 some studies suggest that clinically, WMLs act as risk factors for cortical and the subcortical brain atrophy. 5, 6 Neuronal activity is related to gray matter.
Keywords: arterial stiffness, cerebral small vessel disease, cognitive impairment, geriatric syndrome, white matter hyperintensities. Introduction White matter hyperintensities (WMH) are deﬁned as cerebral white matter changes presumed to be of vascu-lar origin, bilateral and mostly symmetrical. They can appear as hyperintense on T2-weighted.
White matter (WM) disease is recognized as an important cause of cognitive decline and dementia. White matter lesions (WMLs) appear as white matter hyperintensities (WMH) on T2-weighted magnetic resonance imaging (MRI) scans of the brain. Previous studies have shown that type 2 diabetes (T2DM) is associated with WMH.
In this review, we reviewed the literature on the relationship between. Objective: To determine whether magnetic resonance imaging (MRI) white matter hyperintensities (WMH), whole-brain atrophy, and cardiovascular risk factors predict the development of cognitive decline and dementia. Galaxy s9 bixby update Subjects were recruited into this prospective cohort study and followed for incident cognitive decline for mean (SD) () years.
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. White matter hyperintensity volume, local efficiency, and information processing speed scores are interrelated, and local network alterations as response to white matter abnormality explain detrime.
White matter hyperintensities are thought to occur due to chronic hypoperfusion as a result of the small vessel disease. A higher volume of white matter hyperintensities is associated with poorer cognitive outcome in older adults (Prins ND et al., ; Brickman et al., ; Dalen et.

Background and purpose: Elevated levels of amyloid deposition as well as white matter damage are thought to be risk factors for Alzheimer Disease (AD). Here we examined whether qualitative ratings of white matter damage predicted cognitive impairment beyond measures of amyloid. Parkinson's disease (PD) is the second‐most common neurodegenerative disorder and affects 2‐3% of adults aged >65 years. Alongside the cardinal motor symptoms, many nonmotor symptoms contribute to reduced health‐related quality of life.
1 Cognitive impairment and dementia are among the most devastating nonmotor symptoms, with deficits occurring in multiple cognitive. White matter hyperintensity (WMH) is a common finding in aging population and considered to be a contributor to cognitive decline. Our study aimed to characterize the spatial patterns of WMH in different severities and explore its impact on cognition and brain microstructure in non-demented elderly.
Clinical evidence suggests that patients with subcortical ischemic vascular dementia (SIVD) perform better at cognitive tests after exercise. However, the underlying mechanism for this effect is largely unknown. Here, we examined how treadmill exercise changes the cognitive function and white matter cellular pathology in a mouse model of SIVD.
Prolonged cerebral hypoperfusion was induced. White matter hyperintensities (WMHs) are implicated in the etiology of dementia. The underlying pathology of WMHs involves myelin and axonal loss due to chronic ischemia. We investigated myelin loss in WMHs and normal-appearing white matter (NAWM) in patients with various degrees of cognitive impairment using quantitative synthetic magnetic resonance imaging (MRI). Chronic small vessel disease consists of bilateral patchy or diffuse white matter changes often observed on imaging studies 6,7.
The Fazekas scale has been proposed to quantify white matter lesions related to leukoaraiosis. This is especially useful in the setting of dementia. CT. non-enhancing white matter hypodensities; MRI. Only a small number of longitudinal studies have examined the role of vascular disease in MCI patients, and results have been conflicting. 7–11 One study found white matter hyperintensities (WMHs) to be associated with the risk of progression from normal cognitive function to MCI, but not from MCI to dementia.
7 This is in line with another report that did not find an association between cerebrovascular. Considered to be rare before the advent of MRI, white matter lesion (WML) pathology is now receiving considerable attention with respect to the understanding of neurobehavioral decline seen in aging and dementia.
1 WMLs appear to be related to chronic microvascular disease and hypoperfusion, 2 and they are known to increase with age. 3 In addition, WML pathology is commonly seen in Alzheimer. We investigated the possible association between muscle mass decline and cognitive impairment in a cross-sectional study of subjects aged 55 years or above. We also evaluated arterial stiffness and white matter hyperintensities (WMHs) as possible underlying mechanisms for this association. BBB dysfunction has been proposed as a cause of WMH, vascular cognitive impairment, and dementia.
2,3 MRI data suggest that leakage of intravascular contrast agent, a marker of BBB dysfunction, is associated with WMH and vascular cognitive impairment. 4 – 8 Association of white matter pathology with BBB dysfunction inferred from detection of extravascular plasma proteins (such as fibrinogen.
White matter hyperintensities (WMH) are associated with cognitive decline. We aimed to identify the spatial specificity of WMH impact on cognition in non-demented, healthy elderly. We quantified WM. Magnetic resonance imaging (MRI) abnormalities attributed to small-vessel disease, such as lacunar infarction and extent of white matter hyperintensities (WMH), have been associated with decreased brain volume, 1 cognitive impairment and cognitive decline, 5,6 and an increased risk of dementia.
7 Epidemiologic studies have shown that risk. Cerebral white matter hyperintensities (WMH) are a frequent finding on MRI scans of elderly subjects with or without dementia. 1–3 Although the appearance of WMH is not specific for etiology, a substantial body of evidence supports the role of microvascular ischemic disease in their pathogenesis in elderly individuals.

ObjectiveHypertension is a risk factor for development of white matter hyperintensities (WMHs). However, the relationship between hypertension and WMHs remains obscure. We sought to. White matter hyperintensities (WMH) are associated with cognitive decline. there is a clinicoradiological discrepancy between the extent of the white matter disease and cognitive impairment. 8 Indeed, P. White matter hyperintensities, cognitive impairment and dementia: an update. Nat Rev Neurol ; By contrast, generalized atrophy is a common feature of vascular cognitive impairment.
Although my colleague rightly states that lacunar infarctions can cause acute cognitive change in some cases, population-based studies show the large majority to be clinically silent, though still strongly linked to progressive cognitive impairment and dementia. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Vascular Dementia. Probability maps of white matter hyperintensities for healthy controls (top row), patients with mild cognitive impairment (middle row) and patients with Alzheimer’s disease (bottom row).
(Courtesy: Acad. Radiol. /dcyk.omskstar.ru) Every year, there are 10 million new cases of dementia, according to the World Health Organization. White Matter Hyperintensities (WMH) is closely associated with multiple brain functions. It is an objective surrogate marker for MCI/dementia. The severity of WMH changes can be estimated by taking the fundus retinal image and put to the ARIA algorithm, the scale ranges from 0 to 3, increasing score means increasing severity.
The study, involving patients at a memory clinic, found that those with cognitive impairment but no dementia (CIND) displayed a significant interaction between the volume of white matter hyperintensities (WMHs) and a measure of global brain amyloid-beta (Abeta) in regard to their performance on the Mini-Mental State Examination (MMSE). Compared with patients without progression of periventricular white matter hyperintensities, those with marked progression showed a significant decrease in global cognition (adjusted mean, −) and a higher risk for incident mild cognitive impairment (odds ratio, ).
