What does white matter signal abnormalities mean?

White matter lesions, quantified as ‘white matter signal abnormalities’ (WMSA) on neuroimaging, are common incidental findings on brain images of older adults. This tissue damage is linked to cerebrovascular dysfunction and is associated with cognitive decline.

What causes abnormal white matter?

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: Long-term high blood pressure. Ongoing blood vessel inflammation.

What is white matter in the brain for kids?

The white matter is the inner part of the brain. It sends information between the nerve cells and the spinal cord, and from one part of the brain to another. PVL occurs because brain tissue has been injured or has died.

How are white matter diseases classified in children?

Develop a framework for making the appropriate diagnosis of leukodystrophy in children. White matter diseases in children are traditionally divided into two categories: dysmyelinating diseases and demyelinating diseases (, 1,, 2 ).

How are white matter disorders affect the brain?

A.Prof Frank Gaillard ◉ ◈ et al. White matter diseases are a group of conditions that predominantly or significantly affect the white matter of the brain. They comprise a vast heterogeneous group and have a variety of appearances and presentations. They cause disease by altering the process of normal myelination .

How are MR images used to diagnose white matter disease?

Twenty-three pediatric patients with white matter abnormalities on MR images were evaluated retrospectively to assess the contribution of MR compared with CT in diag­ nosing these conditions. In addition, the MR findings in major categories of white matter diseases were analyzed for sensitivity in detecting the presence of an abnormality.

What are the effects of white matter injury?

White matter injury (WMI), one of the most common consequences of premature birth, can produce long-term neurodevelopmental deficits. A study by researchers at Children’s National Health System provides direct evidence that targeting specific receptors in white matter cells after brain injury promotes cellular and functional recovery.
