what is cerebral white matter responsible for？
White matter is tissue in the brain composed of nerve fibers. The fibers (called axons) connect nerve cells and are covered by myelin (a type of fat). The myelin is what gives white matter its white color. Myelin speeds up the signals between the cells, enabling the brain cells to quickly send and receive messages.2021年3月4日
Keeping this in consideration,What is white matter in the brain responsible for?
Function. White matter essentially functions in affecting learning and brain functions, modulating the distribution of action potential, and coordinating communication between the different brain regions.
Furthermore,What is the role of gray matter and white matter?
Gray matter is peculiar for containing the neuron cell bodies. The scientific name for the neuron bodies is soma (1). White matter is specific for containing myelinated axons (1). These structures are long relays.
Subsequently,What does white matter mean on an MRI?
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.
Regarding this,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.
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. However, more research must be done for further confirmation.
While white matter disease has been associated with strokes, cognitive loss, and dementia, it also has some physical and emotional symptoms such as balance problems, falls, depression, and difficulty multitasking (e.g., walking and talking.)
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.
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.
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.
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.
