What does too much white matter in the brain mean?

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.

How common are white matter lesions?

White-matter lesions They are highly frequent in the elderly population. In people aged 60–70 years the prevalence is about 87%, whereas the prevalence at the age of 80–90 years even approaches 100% (de Leeuw et al., 2001; Launer, 2004).

What is a white matter infarct?

Initial infarction during the early stages of the disease is often asymptomatic and is thus considered a form of silent stroke.

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

It is not possible to stop disease progression, and it is typically fatal within 6 months to 4 years of symptom onset. People with the juvenile form of metachromatic leukodystrophy, which develops between the age of 4 and adolescence, may live for many years after diagnosis.

How serious is white matter disease?

Summary: More evidence has been accumulated that damage to cognitive areas is widespread from white matter disease. White matter disease is responsible for about a fifth of all strokes worldwide, more than doubles the future risk of stroke, and is a contributing factor in up to 45% of dementias.

Can white matter lesions in the brain be nothing?

White matter lesions observed on brain MRI are usually characteristic and occur in specific areas including the corpus callosum and pons. “However, in many cases, the white matter lesions as isolated observations are nonspecific” and could be due to MS or another cause, explained Drs Lange and Melisaratos.

How does white matter disease affect the brain?

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.

Which is part of the brain protects white matter?

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. This type of brain tissue helps you think fast, walk straight, and keeps you from falling.
