White matter lesions (WMLs) or leukoaraiosis indicate small vessel vascular brain disease as well as degenerative or inflammatory processes. WMLs appear as hyperintense periventricular or subcortical patchy or confluent areas on T2 or fluid-attenuated inversion recovery MRI sequence. 2016-03-25 2021-02-02 2021-02-14 White matter diseases are a group of conditions that predominantly or significantly affect the white matter of the brain. They comprise a vast heterogeneous group and have a variety of appearances and presentations.

Sie kommen mit zunehmendem Alter recht häufig in der Bevölkerung vor. Eine deutsche Bezeichnung dafür ist: Glioseherde. Sie sind Vorboten von Gehirnschlag, Demenz, Alzheimer und Degenerations-Erscheinungen am Auge. The scale divides the white matter in periventricular and deep white matter, and each region is given a grade depending on the size and confluence of lesions 1 . periventricular white matter (PVWM) 0 = absent.

The Fazekas scale is used to simply quantify the amount of white matter T2 hyperintense lesions usually attributed to chronic small vessel ischemia, although clearly not all such lesions are due to this. Current methods for grading white matter lesions rely on little more than the "trained eye," researchers say, using an imprecise three-point scale, with a score of 1 meaning minimal white spots Current methods for grading white matter lesions rely on little more than the "trained eye," researchers say, using an imprecise three-point scale, with a score of 1 meaning minimal white spots, 2021-04-12 White Matter and Neurodegenerative Diseases Jerome A. Barakos Derk D. Purcell In contrast to gray matter, which contains neuronal cell bodies, white matter is composed of the long processes of these neurons.

Multiple Sclerosis Update - American Journal of Managed Care

I’ve worked with medical imaging centers for a number of years so am always interested in learning about specific cases as well as advancements in the imaging field. However, some findings such as sparing the infratentorial white matter, the restricted diffusion, and the prominent involvement of the pallidum are unusual for ADEM. Besides demyelination, the associated punctiform lesions might be consistent with ischemic lesions because of small-vessel vasculitis. can develop white matter disorders as a result of demyelination, dysmyelination, and developmental delay, as well as idiopathically.

White matter lesions

For many years, researchers focused primarily on white matter when it came to MS. And while white matter is important (about 95% of all MS lesions develop there), recent research has revealed that lesions and a decrease in grey matter (also known as brain volume loss) may have a much greater impact on 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). Aging is associated with the appearance of increased white spots visualized on brain MRI scans.
