what is white matter hyperintensities？
Abstract. White matter hyperintensities (WMHs) are brain white matter lesions that are hyperintense on fluid attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) scans. Larger WMH volumes have been associated with Alzheimer's disease (AD) and with cognitive decline.2020年2月1日
Furthermore,Should I worry about white matter hyperintensities?
Conclusion White matter hyperintensities predict an increased risk of stroke, dementia, and death. Therefore white matter hyperintensities indicate an increased risk of cerebrovascular events when identified as part of diagnostic investigations, and support their use as an intermediate marker in a research setting.
Subsequently,What does white matter hyperintensities mean?
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.
Correspondingly,What causes white matter hyperintensities on MRI?
Causes. Small strokes are the most common cause of white spots on a brain MRI. Small strokes are often caused by blockages of small blood vessels due to high blood pressure and/or diabetes. Large strokes are usually caused by heart disease or carotid artery disease.
One may also ask,What does it mean when an MRI shows white matter?
White matter disease is commonly detected on brain MRI of aging individuals as white matter hyperintensities (WMH), or 'leukoaraiosis.” Over the years it has become increasingly clear that the presence and extent of WMH is a radiographic marker of small cerebral vessel disease and an important predictor of the life- ...
Fisher's exact test showed that the prevalence of WMHs was higher in the 41 to 50 age-range group than in the less-than-40 group (P < 0.0001), and higher in the 51 to 60 age-range group than in the 41 to 50 age-range group (P < 0.0001), and higher in the 61 to 70 age-range group than in the 51 to 60 age-range group (P ...

White matter lesions are among the most common incidental findings—which means the lesions have no clinical significance—on brain scans of people of any age. They may also reflect a mixture of inflammation, swelling, and damage to the myelin.
There isn't a specific treatment. The goal is to treat the cause of the damage and stop the disease from getting worse. Your doctor may prescribe medicines to lower your blood pressure or cholesterol.
Symptoms of white matter disease may include:
- issues with balance.
- walking slow.
- more frequent falls.
- unable to do more than one thing at a time, like talking while walking.
- unusual mood changes.
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 sclerosis (MS). Read on to learn more about white matter disease and its symptoms, causes, and prognosis.
See other articles in PMC that cite the published article. “Gray matter” is only one of two types of brain tissue; the other “white matter” is rarely mentioned. Yet white matter makes up half the human brain and has not been thought to be important in cognition or learning outside the context of pathology.
Treatments: While there is no known cure for white matter disease, treatments can help to manage the symptoms. Controlling the risk factors associated with heart disease can help decrease the progression of the disease.
