What causes white matter changes in the brain?

Having cardiovascular risk factors, such as high blood pressure, elevated blood sugar (from diabetes), high dietary fat intake (high cholesterol) and smoking can all increase the number of white matter spots or lesions in your brain.

What does an abnormality in white matter in the brain mean?

White matter disease is a disease that affects the nerves that link various parts of the brain to each other and to the spinal cord. 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.

Should I be concerned about white matter in the brain?

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- ...

What does white matter on brain MRI mean?

White matter lesions (WMLs) are areas of abnormal myelination in the brain. These lesions are best visualized as hyperintensities on T2 weighted and FLAIR (Fluid-attenuated inversion recovery) sequences of magnetic resonance imaging. They are considered a marker of small vessel disease.

Severity of White Matter Hyperintensities & All-Cause Mortality

How do you get white matter disease?

White matter disease is a progressive disorder caused by age-related decline in the part of the nerves (the white matter) that connect different areas of brain to each other and to the spinal cord. This disorder can result in memory loss, imbalance and can lead to problems with mobility in older age.

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.)

What is the prognosis for 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 inherited?

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.

Can stress cause white matter lesions?

Increased exposures to stressful events are associated with a corresponding increase in the progression of white matter hyperintensities.

Are white matter signal abnormalities clinically relevant?

From a research perspective, we have come to understand that there is at least a weak relationship between white matter signal abnormalities and cognition, although the jury is still out about whether and to what extent this is clinically meaningful.

What do white matter lesions indicate?

White matter lesions (WMLs) or leukoaraiosis indicate small vessel vascular brain disease as well as degenerative or inflammatory processes. WMLs appear as hyperintense periventricular or subcortical patchy or confluent areas on T2 or fluid-attenuated inversion recovery MRI sequence.

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.

What is the life expectancy of someone 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.

Can white matter disease disappear?

VWM is chronic and progressive, and is unusual in that periods of rapid and severe deterioration can be caused by minor head trauma, fevers and even anesthesia. Although there is currently no cure for VWM, it is treatable.

Is white matter disease 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.

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.

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.

Can white matter disease be misdiagnosed?

We have seen several patients in whom we believe MS was misdiagnosed, based on observation of white matter lesions. As MS is rare, and migraine extremely common (roughly 14% of population), there is a substantial chance of a false positive diagnostic error.

What type of 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.

What disease mimics multiple sclerosis?

These include fibromyalgia and vitamin B12 deficiency, muscular dystrophy (MD), amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease), migraine, hypo-thyroidism, hypertension, Beçhets, Arnold-Chiari deformity, and mitochondrial disorders, although your neurologist can usually rule them out quite easily.

Is white matter disease the same as vascular dementia?

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).

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.

How common is white matter in brain?

In the general population the prevalence of white matter hyperintensities ranges from 11-21% in adults aged around 64 to 94% at age 82. Pathological findings in regions of white matter hyperintensity include myelin pallor, tissue rarefaction associated with loss of myelin and axons, and mild gliosis.

What causes white matter lesions on MRI?

White spots on a brain MRI are not always a reason for concern. There are many possible causes, including vitamin deficiencies, infections, migraines, and strokes. Other risk factors for white spots include age, genetics, obesity, diabetes, hypertension, and high cholesterol.
