What does white matter mean on an MRI?
What does white matter mean on an MRI?
Axons are surrounded by a fatty material called myelin, which insulates them like a sheath and gives white matter its color. Abnormalities in white matter, known as lesions, are most often seen as bright areas or spots on MRI scans of the brain. They can reflect normal aging; white matter deteriorates as people age.
What does non specific mean on MRI?
Non-specific is used for a symptom, sign, test result, radiological finding, etc., that does not point towards a specific diagnosis or etiology. For example, a high T2 signal lesion of the white matter on an MRI brain is a non-specific finding as the number of possible causes is broad.
What does nonspecific white matter lesions 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.
What is another word for non specific?
broad. casual. delinquent. derelict. devil-may-care.
Can stress cause changes in white matter?
Increased exposures to stressful events are associated with a corresponding increase in the progression of white matter hyperintensities.
What does nonspecific mean in medical terms?

What does a non specific diagnosis mean?
A “nonspecific symptom” is something that is reported by a patient but cannot be observed. Nonspecific symptoms may include chronic fatigue or pain that is not related to a known injury. For all its complexity, the body has only so many ways to show injury and so many ways to combat disease.
Does depression cause white matter on the brain?
Depression has been shown to alter the structure of the brain’s white matter, which contains the circuitry that allows brain cells to communicate with each other, and which underpins brain function.
