Hyperintensitet – Wikipedia

White spots may be described in your MRI report as high signal intensity areas, white matter hyperintensities, leukoaraiosis (often used if spots are felt to be caused by decreased blood flow), or nonspecific white matter changes. They are usually found in the brain’s white matter, typically near the ventricles. Background: White matter hyperintensities of presumed vascular origin (WMH) are one of the imaging features of cerebral small vessel disease. Controversies persist about the effects of WMH on cognitive dysfunction. 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. White matter hyperintensity can occur in various places in the brain.

Finally, what is known as deep hypertensity can be observed in the depths of the brain's white matter. 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. 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 Hyperintensities at the age of 30-40: The white matter disease is common in the brains of healthy individuals in their 60s and rarely seen at the age of thirty and forty. Interaction with environmental factors, appear to be important.

The study results suggested that white matter hyperintensities (WMH) “are partly independent of vascular pathology and associated with the neurodegenerative process,” according to the researchers.

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.

In a meta-analysis of case-control studies, migraine was associated with an increased prevalence of white matter hyperintensities compared with absence of migraine (odds ratio [OR], 3.9; 95% CI, 2.26-6.72). 1 A separate population-based study showed that the risk of supratentorial deep white matter hyperintensity was highest in women with migraine (OR, 2.1; 95% CI, 1.0-4.1), particularly among 2021-03-12 · Improved Automatic Segmentation of White Matter Hyperintensities in MRI Based on Multilevel Lesion Features., UNED, Madrid, Spain.

12.1 Introduction. Diffuse white matter hyperintensities on brain MRIs are a common finding with an extensive differential diagnosis. In this chapter, we describe a case in which a diagnosis of CNS demyelination was highly suggested based on the appearance of white matter lesions identified on MRI. White matter hyperintensities (WMH), which are typically detected on fluid-attenuated inversion recovery (FLAIR) brain MRI, are common findings in older adults. WMH are considered a type of sporadic small vessel disease (Wardlaw and Pantoni, 2014).
