White matter disease of the brain: what do we know about it? Should I worry? Dear Jennifer, white matter lesions can be seen on a brain MRI and can be due to a variety of disease processes. As I stated in my posts just what do these white matter lesions signify can only be determined accurately by correlating the MRI findings to the patient’s history and examination findings.

CPMC Brain Health Center Considers these Diseases and Conditions that Affect Memory Many individuals with Parkinson’s develop dementia in later stages of the disease, which does not affect memory like in Alzheimer’s disease, but rather affects concentration, visual spatial skills, and speed of thinking.

What Is White Matter Disease? Many different diseases, injuries, and toxins can cause changes in your white matter. Doctors point to the same blood vessel problems that lead to heart trouble or strokes: 1  Long-term high blood pressure.  Ongoing blood vessel inflammation.

Leukoaraiosis These white matter changes are also commonly referred to as periventricular white matter disease, or white matter hyperintensities (WMH) due to their bright white appearance on T2 MRI scans. Many patients can have leukoaraiosis without any associated clinical abnormality.hite 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.

What is white matter disease? It might be a cause of vascular dementia 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.

Diagnosis of White Matter Damage (WMD) MainPlaceHolder. White matter in the brain is made of axons, which are like wires that carry messages between neurons and supporting cells. White matter sits underneath the brain’s cortex, or grey matter. In general, white matter damage (WMD) is caused by a lack of oxygen to that part of the brain. Periventricular leucomalacia (PVL) is a condition in which decreased blood flow to brain tissue causes it to soften up and eventually die.

Clinical Applications of Imaging Disease Burden in Multiple Sclerosis The exact mechanism by which brain atrophy occurs remains incompletely understood. Axonal loss within white matter lesions probably contributes to brain atrophy by two mechanisms: the amount of tissue lost within the lesions themselves, and Wallerian degeneration in pathways related to the lesions.

- Moreover, white matter is classically considered less vulnerable than gray matter to the ischemic injury initiated by a large-artery occlusion. 6 However, ischemia may primarily involve white matter (“capsular infarcts”), sometimes in an isolated fashion.bstract. Background and Purpose The effects of ischemia on the cerebral white matter structure seldom have been studied, possibly because white matter is generally considered less vulnerable to ischemia than gray matter.

PERIVENTRICULAR WHITE MATTER LESIONS (PWM) White matter lesions are best seen on the FLAIR MRI sequence of brain imaging. CT scans are not nearly as sensitive. The better (stronger) the MRI magnet, the more lesions are seen. Thus, MRI's done on contemporary 3T units will see more and smaller white matter lesions than scans done on open scanners.

The Effects of âWhite Matterâ in the Brain The hypothesis suggests that white matter lesions may lead to disrupted structural connectivity within the brain along what are known as neural “tracks.” These disruptions could then lead to functional deficits, in turn contributing to behavioral impairments.

- As the disease advances, brain weight is reduced and white matter atrophy develops. On microscopic examination, numerous vacuoles are seen in the deeper cortical layers, cortex-white matter junction, white matter and cerebellum, imparting a spongy appearance to the affected areas which gave the disease its name.

White matter disease exacts heavy toll, increasing risk of stroke, Alzheimer's, dementia 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. The disease hardens the tiny arteries, gradually restricting nutrients to white matter -- the connections between brain regions involved in executive abilities such as planning, organizing, problem-solving, and attention.

Chronic Stress Can Damage Brain Structure and Connectivity Rats who have high levels of cortisol and chronic stress had fewer neurons overall but a big increase in oligodendrocytes. By blocking the equivalent of cortisol receptors, the researchers discovered the process was tied to the stress hormone.“This was absolutely not what we were expecting to find,” Kaufer said.he gray matter of the brain is densely packed with nerve cell bodies and is responsible for the brain's higher functions, such as thinking, computing, and decision-making. But gray matter is only half of the brain matter inside our heads—the other half of brain volume is called white matter.

- Less blood flow means that the brain tissue can be irreversibly injured, which is referred to as ischemic injury.. Some MRI reports may state that perivascular chronic ischemic white matter disease of aging is seen. We do know that we see increasing amount of these changes with age and see greater amounts of change in patients who have high blood pressure and diabetes.

Encephalomalacia Encephalomalacia refers to the softening of brain matter after a stroke or a severe head trauma while Gliosis is a disease that leads to the development of astrocytes (glial tissue). Imaging tests often show the Gliosis as a “scar” at the brain injury site.

White Matter in the Brain 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.

What Is White Matter Disease? White matter disease is the wearing away of tissue in the largest and deepest part of your brain due to 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. A fatty material called myelin protects the fibers and gives white matter its color.

Brain Diseases Inflammation in the brain can lead to problems such as vision loss, weakness and paralysis. Loss of brain cells, which happens if you suffer a stroke, can affect your ability to think clearly. Brain tumors can also press on nerves and affect brain function. Some brain diseases are genetic. And we do not know what causes some brain diseases, such as Alzheimer's disease. The symptoms of brain diseases vary widely depending on the specific problem. In some cases, damage is permanent. In other cases, treatments such as surgery, medicines, or physical therapy can correct the source of the problem or improve symptoms.
