Als White Matter Lesion (WML) bezeichnet man Schäden an der weißen Substanz, die mit zunehmendem Alter recht häufig in der Bevölkerung auftreten und die mit kognitiver Beeinträchtigung und Gehirnschlag in Verbindung stehen.

Retinal arterial changes correlate with cerebral small-vessel disease. Progression of white matter lesion volume and health-related quality of life in patients

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. 1 = “caps” or pencil-thin lining. 2 = smooth “halo”.

White matter lesions

The brain's white matter is situated under the surface gray matter or cerebral cortex New research shows that migraines may not be as benign as we once thought. New research shows that migraines may not be as benign as we once thought. People who experience migraine headaches have a greater risk of developing brain lesions a White matter disease is an age-related disease. We explain its causes and life expectancy. Overview White matter disease is a disease that affects the nerves that link various parts of the brain to each other and to the spinal cord.

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. If the nervous system were a computer network, gray matter – a non-myelinated portion that contains nerve cells and capillaries – would be the computers and white matter the cables.

May 14, 2018 White matter lesions (WML), as seen on brain MRI, are a biomarker of cerebral small vessel disease (CSVD) which is common in older people.

The presence of these anomalies, called white matter hyperintensities, characterizes elderly subjects as well as ischemic stroke patients, regardless of their age. 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, White matter refers to areas of the central nervous system (CNS) that are mainly made up of myelinated axons, also called tracts.

White matter disease, or leukoaraiosis, involves the degeneration of white matter in the brain. White matter is tissue that includes nerve fibers (axons), which connect nerve cells. A fatty tissue

Alexander disease 3. Vanishing white matter disease. 4. Als White Matter Lesion (WML) bezeichnet man Schäden an der weißen Substanz, die mit zunehmendem Alter recht häufig in der Bevölkerung auftreten und die mit kognitiver Beeinträchtigung und Gehirnschlag in Verbindung stehen.

The mean size of the lesions was 5.1 ± 4.5 mm (minimum, 2 mm; maximum, 24 mm). Repeated radiological evaluations were performed in 11 (47.8%) of the patients. No new white matter lesions were detected in control MRI during follow up. Conclusion The marked sensitivity of T2-weighted images (T2WI) allows white matter lesions to be readily detected, providing high sensitivity to lesion detection. However, the difficulty confronting the radiologist is that a wide gamut of diseases may involve the white matter, and thus white matter lesions are often nonspecific in nature, that is, low specificity.

Aging is associated with the appearance of increased white spots visualized on brain MRI scans. The presence of these anomalies, called white matter hyperintensities, characterizes elderly subjects as well as ischemic stroke patients, regardless of their age.

They comprise a vast heterogeneous group and have a variety of appearances and presentations. They cause disease by altering the process of normal myelination.
