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.
What causes too much white matter in 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.

How does white matter affect the brain?
Symptoms. White matter plays an essential role in communication within the brain and between the brain and spinal cord. As a result, damage to this tissue can lead to issues with: In the beginning stages of progressive white matter disease, the symptoms may be mild. As time passes, however, the symptoms may get worse.
What is the white matter?
Degeneration of the white matter — specifically, the myelin sheaths — can affect a person’s mood, focus, muscle strength, vision, and balance. 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).
What is white matter disease?
Summary. White matter disease, or leukoaraiosis, involves the degeneration of white matter in the brain. White matter is tissue that includes nerve fibers (axons), which connect nerve cells. A fatty tissue called myelin covers the axons. These axons connect the neurons of the brain and spinal cord and signal nerve cells to communicate ...

What is the name of the MRI that shows the white matter of the brain?
An MRI is a scan of your brain using magnetic resonance. To see the white matter of your brain, your doctor may use a specific type of MRI called T2 Flair.

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. depression. unusual mood changes.
What is white matter?
These nerves are also called white matter. White matter disease causes these areas to decline in their functionality. This disease is also referred to as leukoaraiosis. A person with white matter disease will gradually have increasing difficulty with the ability to think. They’ll also have progressively worsening issues with balance.
Is white matter disease age related?
They’ll also have progressively worsening issues with balance. White matter disease is an age-related, progressive disease. Age-related means that it usually affects older people. Progressive means that it gets worse over time.
Can white matter be caused by strokes?
There’s at least one study that seems to show that white matter disease may be caused by strokes so small they’re unnoticeable to those having them. These small, unnoticeable strokes are also called silent strokes. These silent strokes are believed to damage white matter, and therefore cause white matter disease.
How important is white matter?
We now know, however, how important white matter is to our overall brain health and cognitive ability, as well as how declines in white matter are correlated with impairments in brain functioning.
What is white matter?
Want more of a biological explanation? 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.
What is the function of myelin?
Myelin speeds up the signals between the cells, enabling the brain cells to quickly send and receive messages. It also provides insulation for the fibers, preventing the brain from short-circuiting. White matter makes up about half of the brain, with gray matter making up the other half. 1 . How Your Brain Works.

Example
Overview
- White matter hyperintensities is a term you might hear used to describe spots in the brain that show up on magnetic resolution imaging (MRIs) as bright white areas. 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. The presence of white m…
Causes
- White matter hyperintensities are often referred to as white matter disease. Initially, white matter disease was thought to simply be related to aging. However, we now know that there are also other specific risk factors for white matter disease which include high blood pressure, smoking, cardiovascular disease, and high cholesterol.
Symptoms
- 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 with such activities as walking and talking.
Research
- Some research has found that physical exercise, in particular, cardiorespiratory activities and weight resistance training, was correlated with improved white matter integrity in the brains of those who participated in those studies. Other research found that when adults learned new skills, the amount of white matter in their brains increased. This...
Prognosis
- Physical exercise has also been connected to a decreased risk of dementia as well as a slower cognitive decline in people who already have been diagnosed with Alzheimer's or another kind of dementia.
Benefits
- White matter functioning was also improved by the practice of meditation, and the difference was observed in as little as in two to four weeks.
Treatment
- If you're looking for that small nudge towards a healthier lifestyle, the research about exercise, mental activity, and meditation may help motivate you toward the reward of improved body and brain health.
