what is white matter on the brain？
White matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Myelin gives the white matter its color.2021年1月28日
Considering this,What does it mean when you have white matter on the brain?
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 axons, that connect other parts of the brain and spinal cord and signal your nerves to talk to one another.
Also asked,Is white matter on brain serious?
Originally, white matter disease was considered a normal, age-related change. But over the last decade, medical experts have come to understand that the presence of large areas of disease in the white matter of the brain are associated with cognitive decline and dementia in patients.
Thereof,How serious is white matter disease?
The life expectancy after a diagnosis of white matter disease depends on the speed it progresses and the severity of any other conditions it may cause, like stroke and dementia. White matter disease is believed to be a factor in both strokes and dementia.
Beside above,What does it mean when you have white matter on a brain MRI?
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- ...
White matter has a legitimate position in the study of dementia. The neuropathology of white matter disorders is typically diffuse or widespread, thus disrupting many networks simultaneously and producing a multi-domain syndrome that merits the term dementia.
In general, the prognosis is grave, with the majority of patients dying after a few years. However, some die only after several months, and some manage to survive for several decades .
Unlike Alzheimer's disease which shrinks the hippocampus causing progressive memory loss, white matter disease is a more diffuse mind-robbing condition that targets small blood vessels deep within the brain's white matter.
Vanishing white matter disease This is a rare inherited condition that can develop during childhood. It is characterized by early childhood onset of chronic neurological deterioration.
“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. That view could change.
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.
A radiologist, particularly a neuroradiologist, has expertise in what the brain should look like on an MRI. When evaluating for white matter disease, the radiologist will be looking for abnormal signal in the brain tissue.
Background: The association between pain and dementia is complicated and may depend on underlying brain pathology. It was hypothesized that both medial temporal atrophy (MTA) and global cortical atrophy (GCA) predicted no/mild pain, while white matter hyperintensities (WMH) predicted moderate/severe pain.
