White matter refers to areas of the central nervous system (CNS) that are mainly made up of myelinated axons, also called tracts. Long thought to be passive tissue, white matter affects learning and brain functions, modulating the distribution of action potentials, acting as a relay and coordinating communication between different brain regions.


Cerebral white matter lesions (WML) are considered manifestations of cerebral small vessel disease, 14,15 leading to an increased risk of stroke, cognitive decline, dementia, disability, and mortality. 16,17 The prevalence of WML ranges from 11% to 21% in adults aged around 64% to 94% at age over 80, 18 and it is highly associated with the distribution of the main cardiovascular risk factors

Heart failure is independently associated with white matter lesions: insights from the population-based LIFE-Adult Study. ESC Heart Fail . Published online MS lesions can occur in both grey and white matter and lead to the symptoms you experience. 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 90,000 U.S. doctors in 147 specialties are here to answer your questions or offer you advice, prescriptions, and more.

can develop white matter disorders as a result of demyelination, dysmyelination, and developmental delay, as well as idiopathically. Using Poser's classification of white matter diseases, demyelinating lesions may be divided into primary disorders, such as multiple sclerosis (MS) and acute disseminated encephalomyelitis (ADEM), 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 2020-10-27 · 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, while grades of 2 or 3 suggest more significant disease. Causes. 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.

White matter lesions

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. They cause disease by altering the process of normal myelination. Nevertheless, consideration of the disorders in which white matter is significantly affected serves to highlight both the frequency with which white matter lesions are encountered and the tendency of these lesions to produce patterns of neurobehavioral dysfunction similar to gray matter lesions.

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.

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

When they occur along with other symptoms, they are often indicative of a neurological disorder and impaired neurological function. They are also common in the elderly and are considered normal with aging when they occur in very small areas. 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). WMH’s are also referred to as Leukoaraiosis and are often found in CT or MRI’s of older patients. Chronic white matter lesion activity measured by longitudinal T1 hypointense lesion volume accumulation in slowly expanding/evolving lesions and in non-slowly expanding/evolving lesion areas of pre-existing lesions predicted subsequent composite disability progression with consistent trends on all components of the composite. White matter diseases are a group of conditions that predominantly or significantly affect the white matter of the brain.
