What is Vwm disease?

Vanishing white matter (VWM) disease is an inherited condition caused by a faulty gene. Children with VWM disease have a defective protein that prevents the body from making enough myelin, a white, fatty substance that insulates nerve fibers, protecting them from damage.

What is the life expectancy of a child with leukodystrophy?

The prognosis for MLD is poor. Most children within the infantile form die by age 5. Symptoms of the juvenile form progress with death occurring 10 to 20 years following onset. Those persons affected by the adult form typically die withing 6 to 14 years following onset of symptoms.

What are the symptoms of white matter disease?

What is the meaning of VWM?

Vanishing White Matter Disease (VWM) is one of more than 50 conditions that affect the white matter, or myelin, of the brain known collectively as Leukodystrophies.

Is there a cure for white matter disease?

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.

Tackling a rare brain disease that affects children

What is the life expectancy of someone with white matter disease?

Within 2 years, children can develop gait and posture problems, as well as blindness and paralysis. It is not possible to stop disease progression, and it is typically fatal within 6 months to 4 years of symptom onset.

Is white matter disease the same as Alzheimer's?

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.

What is the cause of 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.

What causes white matter disease in children?

Vanishing white matter (VWM) disease is an inherited condition caused by a faulty gene. Children with VWM disease have a defective protein that prevents the body from making enough myelin, a white, fatty substance that insulates nerve fibers, protecting them from damage.

What does white matter do in the brain?

In the most general sense, the gray matter of the brain facilitates information processing, and the white matter facilitates information transfer; both are critical for efficient operation of the neural networks responsible for a specific mental domain.

Does white matter mean dementia?

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.

What doctor treats white matter 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.

Is white matter disease the same as MS?

White Matter Consists Mainly of Nerve Fibers

In MS, the immune system attacks the myelin in the brain, spinal cord, and optic nerves. The attack causes inflammation that eventually leads to sclerosis, which is the medical term for scarring. (That's how MS got its name.)

Can leukodystrophy be cured?

There's no cure for leukodystrophy. The following treatments may ease symptoms and preserve some neurological function: Medication for seizures, muscle tightness and movement problems. Nutritional therapy or feeding tubes for eating and swallowing problems.

Is leukodystrophy painful?

Symptoms of metachromatic leukodystrophy may include seizures, personality changes, spasticity, progressive dementia, painful paresthesias, motor disturbances progressing to paralysis, and/or visual impairment leading to blindness.

What are the signs and symptoms of leukodystrophy?

Are you born with white matter disease?

While childhood onset is the most common form of leukoencephalopathy with vanishing white matter, some severe forms are apparent at birth.

Can white matter in the brain be repaired?

White matter injuries are very serious, but, depending on the type and extent of the injury, extensive recovery may occur. As long as the neuron cell bodies remain healthy, axons can regrow and slowly repair themselves.

Does white matter disease cause headaches?

Patients with extensive white matter hyperintensities are likely to have tension-type headaches or to have headaches develop during middle age, according to results published in Cephalagia. Currently, there are no established treatments or strategies for managing white matter hyperintensities.

What does white matter on brain MRI mean?

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- ...

Does alcohol affect white matter?

In contrast, human neuroimaging studies have generally found that alcohol is associated with deleterious changes in the brain including global and regional brain shrinkage and white matter damage, with frontal lobes being particularly affected (Oscar-Berman and Marinkovic, 2007; Sullivan et al., 2010).

Is white matter disease and vascular dementia the same thing?

White matter disease (WMD), also called multiple cerebral infarction, is regarded as the common cause of “mild” dementia in the elderly, and if dementia is the main problem, it is called a vascular dementia (Roman et al., 1993).

At what age does the average human have the most white matter?

It starts and ends with roughly the same amount of white matter and peaks between ages 30 and 50. But each of the 24 regions changes a different amount. Some parts of the brain, like those that control movement, are long, flat arcs, staying relatively stable throughout life.

Does everyone have white matter in the brain?

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.

Does white matter increase with age?

Age-correlated studies reveal that the changes in white matter may be much higher than those of gray matter (Miller et al., 1980). Upto 40 years of age, the white matter volume increases and is closely related to the formation of the myelin sheath (Courchesne et al., 2000; Bartzokis, 2004).
