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 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.
When it occurs in the basal ganglia part of the brain, this is called subcortical hyperintensities. Near lateral ventricles, a periventricular hyperintensity can be observed. Finally, what is known as deep hypertensity can be observed in the depths of the brain's white matter.

Each of these leads to a global impairment of the neural myelination process through the secondary destruction of previously myelinated structures. White matter hyperintensities increases with traumatic brain injury severity: associations to neuropsychological performance and fatigue Nils Berginströma,b, Peter Nordströma, Lars Nybergc,d,g*, and Anna Nordström e,f* White Matter Hyperintensities Segmentation Review Balakrishnan, Valdes-Hernandez and Farrall 1 Automatic Segmentation of White Matter Hyperintensities from Brain Magnetic Resonance Images in the Era of Deep Learning and Big Data – A Systematic Review Ramya BalakrishnanϮ1,3, Maria del C.

The degree of WMH severity was rated visually on axial FLAIR images using the modified Fazekas scale (WMH White matter hyperintensities (WMHs) are a common finding on magnetic resonance imaging (MRI) scans of elderly subjects. Despite their frequency, the clinical correlates and etiology of WMH remain controversial, with many conflicting results published.
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. 2021-02-18 · Increased white matter hyperintensities occurred frequently among patients with behavioral-variant frontotemporal dementia and Alzheimer’s disease in a cross-sectional MRI study published in Background: Hypertension and white matter hyperintensities (WMH) are mutually associated risk factors for cognitive impairment.

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.
N2 - White matter hyperintensities (WMH) in Mild Cognitive Impairment (MCI) have been associated with impaired executive functioning, although contradictory
Background: White matter hyperintensities of presumed vascular origin (WMH) are one of the imaging features of cerebral small vessel disease.

Olika författare har uppgett 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. 3 They are more common in individuals with a history of cognitive impairment, dementia, or cerebrovascular disease. 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).

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. hyperinflation · Hyperion · hypericum · hyperionism · white matter hyperintensities.
