White Matter Hyperintensities on Magnetic Resonance

  1. 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
  2. White matter hyperintensities and lacunar infarcts are usually thought to be concomitant expressions of arteriolosclerotic disease. 1 These results indicate that white matter hyperintensities in certain individuals may also represent something else besides the generally accepted concept of small vessel disease or be the very initial phase of such sclerosis that in combination with some other mechanism can affect cognition and to some extent mortality
  3. There are several causes of white spots on a brain MRI, including small strokes, migraines, multiple sclerosis (MS), lupus, B12 deficiency, a brain tumor such as lymphoma, or an infection such as Lyme disease or HIV. 1  Sometimes the white matter hyperintensities can resolve, as with a treated infection or brain tumor
  4. White matter hyperintensities in the brain may indicate Alzheimer's disease. 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
  5. White matter hyperintensities are a predictor for vascular disease for which age and high blood pressure are the main risk factors. The review showed that WMHs are significantly associated with an increased risk of stroke
  6. Seen on brain magnetic resonance images as ultra-white patches, white matter hyperintensity indicates injury to the axons, DeCarli explains, possibly representing loss of blood flow. Neurologist Charles DeCarli is zeroing in on the role that vascular disease plays in Alzheimer's disease

Defined by Hachinski in 1985leukoaraiosis implies diminished density of white matter which is seen on brain computed tomography (CT), which in turn is hyperintense on T2-weighted, proton-density, and fluid-attenuated inversion recovery (FLAIR) brain MRI sequences.[2-3] Over the years, MRI has demonstrated greater sensitivity of detecting abnormal white matter, including lesions not otherwise visible on head CT White matter disease is the wearing away of tissue in the largest and deepest part of your brain that has a number of causes, including aging. This tissue contains millions of nerve fibers, or.. 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

Hyperintensity is a term used in MRI reports to describe how part of an image looks on MRI scan. Most MRIs are in black/white with shades of gray. A hyperintensity is an area that appears lighter. 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 disease may develop with conditions associated with aging, such as stroke, but it can also affect young people due to conditions such as cerebral adrenoleukodystrophy and multiple.. 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

I then end up with an MRI report that shows white matter hyperintensities (WMH). WMH are lesions in the brain that show up as areas of increased brightness on specific MRI sequences. They may be caused by wear and tear of the cerebral vessels which can result in strokes or in inflammatory disorders such as multiple sclerosis White matter hyperintensities (WMH) are a common feature of cerebral small vessel disease (SVD) on brain MRI. 1 Among several adverse clinical effects, WMH are associated with worsening cognition, double the risk of dementia, and triple the risk of stroke. 2 A high WMH burden, vascular risk factors (particularly hypertension), and increasing age are associated with WMH, 3 but other factors. Though it is believed that white matter hyperintensity burden reflects chronic small vessel damage, the pathological etiology is multifactorial and not well understood, and the pathogenesis may vary by location and type of lesions. 1 Vessel wall thickening, blood-brain barrier breakdown with vessel leakiness, and altered reactivity contribute to white matter disease associated with hypertension and amyloid deposition 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. These nerves are also called white matter. White matter disease..

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 White matter hyperintensities (WMH) of presumed vascular origin are frequently observed in older individuals on brain MRI and are an important cause of cognitive decline and dementia. 1,-, 3 They are considered hallmark features of cerebral small vessel disease (CSVD). 4,5 WMH are heterogeneous lesions that correspond to different underlying brain parenchymal changes. 6,-, 8 Previous studies. White matter hyperintensities are sections of the white matter that appear as brighter white patches on the white matter on MRIs. They're small infarcts (areas of tissue that undergoes tissue death due to cessation of the blood supply) and indicate damage to the axons. WMHs can have causes other than Migraine

White matter hyperintensities (WMH) are striking abnormalities that are often found on T2-weighted and fluid-attenuated inversion recovery (FLAIR) images in the elderly White matter hyperintensities (WMH) is a non-specific term that refers to white matter (WM) signal hyperintensity areas on T2 weighted MRI scans, and correlates with WM rarefaction (leucoaraiosis) as defined on CT scans. 1 The main risk factors associated with development of WMH are older age and blood hypertension. 2 WMH occur both in demented patients and in healthy elderly subjects, and their relevance to cognitive status has not been fully established The diagnostic value of white matter hyperintensities (WMH) in different types of migraineare unknown. To evaluate the WMH pattern of different subtypes in migraine patients with no vascular risk factors. 92 migraine patients (73 females, mean age 34.6 ± 8.9; 61 episodic migraine, 31 chronic migraine, 36 migraine with aura, 56 migraine without aura) without vascular risk factors underwent. Patients with migraine are at increased risk for white matter hyperintensities detected on magnetic resonance imaging. The presence of nonspecific white matter hyperintensities may cause uncertainty for physicians and anxiety for patients. The pathophysiology and long-term consequences of these lesions are unknown
