What are white matter lesions?

Table of Contents

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 causes lesions in the white matter?

White matter lesions can be seen in a range of neurologic disorders, most often with vascular diseases such as stroke, migraine, and multiple sclerosis (MS).

Is white matter the same as lesions?

White Matter Lesions on Magnetic Resonance Imaging. White matter lesions (WMLs), also called white matter hyperintensities, are a common finding on T2 and fluid-attenuated inversion recovery (FLAIR) sequences on brain magnetic resonance imaging (MRI).

What happens if white matter is damaged?

White matter plays an essential role in communication within the brain and between the brain and spinal cord. As a result, damage to this tissue can lead to issues with: problem-solving. memory and focus.

What are the symptoms of white matter lesions?

Symptoms of white matter disease may include:

issues with balance.
walking slow.
more frequent falls.
unable to do more than one thing at a time, like talking while walking.
depression.
unusual mood changes.

How common are white matter lesions?

White matter lesions are often found on MR scans of elderly people, they are attributed to degenerative changes of long penetrating arteries. 1-6 Reported prevalence ranges from 5% to 90%, depending on study design, study population, and rating scales.

What types of symptoms can damage to the white matter cause?

Can white matter lesions heal?

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.

How do you treat white matter lesions?

There isn’t a specific treatment. The goal is to treat the cause of the damage and stop the disease from getting worse. Your doctor may prescribe medicines to lower your blood pressure or cholesterol.

What is a white matter lesion?

Continuing Education Activity 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.

How are white matter lesions (WMLS) evaluated in cerebral small vessel disease?

Evaluation of patients presenting with white matter lesions (WMLs) depends on the age of the patient, clinical scenario, and pattern of white matter lesions on MRI. WMLs on MRI are common manifestations of cerebral small vessel disease and are associated with vascular risk factors.

Why is pattern recognition of white matter lesions in MRI important?

Pattern recognition of white matter lesions (WMLs) in MRI is crucial as it may make the diagnosis in many conditions. The differential diagnosis for symmetric WMLs: Bilateral Hemispheres: Toxic encephalopathy, HIV encephalopathy, autoimmune encephalopathies, and Vitamin B12 deficiency
