White Matter (Overview)

White matter is one of the two components of the central nervous system and consists of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centers. White matter tissue of the freshly cut brain appears pinkish white to the naked eye because myelin is composed largely of lipid tissue veined with capillaries.

What are white matter lesions?

Brain: These are found on MRI and ct of the brain. It is non specific and just means that the brain has some "scarring" for lack of a better term. Seen in patients over 65 commonly near the ventricles of the brain.

What does it mean "may be very slightly more conspicous" for a white matter lesion?

What does it mean "may be very slightly more conspicous" for a white matter lesion?

Generic response: If a pre-existing white matter lesion has become larger or more prominent, this could be a sign of disease activity in form of inflammation, but could also be a feature of a stronger magnet or a more precise MRI device. You need to talk to your doctor regarding correlation with your symptoms.

What is chronic white matter ischemic disease?

What is chronic white matter ischemic disease?

Lack of blood deep: In the brain. This condition is most commonly seen in individuals with one or all of the following: 1. Hypertension 2. Diabetes 3. Hyperlipidemia (high cholesterol) 4. Cigarette smoking 5. Family history of stroke of course there are others but these are most important. Please meet with your neurologist to discuss why and what you can do to help your situation. Good luck and well wishes.

Mild supratentorial white matter disease--what is this?

Mild supratentorial white matter disease--what is this?

Maybe of no signif.: White matter lesions may be caused from a host of circumstances, such as migraine, prior head or neck trauma, hardening of the arteries, inflammation like multiple sclerosis, prior small strokes, effect of some medications such as methotrexate, and is not specific. The location of your concern maybe actually a chronic, lifelong issue. Consult your doctor.

What is chronic white matter Ischemia and what are the symptoms?

What is chronic white matter Ischemia and what are the symptoms?

Vague finding: The best way to describe this, as blood vessels in your brain branch out and become smaller and smaller, the very smallest are prone to calcium build up and atherosclerotic disease as we age. This is what radiologists often report as chronic ischemic white matter disease on MRI. Just like with heart disease, some have it worse or earlier than others.

What's the difference between white matter lesions and perivascular spaces? There's a possibility to one mimic the other?

What's the difference between white matter lesions and perivascular spaces? There's a possibility to one mimic the other?

MRI findings: Sometimes perivascular spaces look like changes in the white matter. They are terms used to describe nonspecific findings. White matter lesions are normally discrete, not nearby blood vessels, and sometimes have MRI characteristics that help us know they are due to a stroke or MS. It is possible that one looks like the other, depending on what kind of MRI is done, and who is interpreting it.

White matter in feces?

White matter in feces?

Prob diet related: Flecks of white stuff are probably diet related. Sometimes some meds have casings that pass undigested. Parasites can be white-but generally if you can see them, they will be moving (worms). Entirely white stools can be seen after taking barium for a test, some meds, or with blockage to the flow of bile. That last one needs medical evaluation-potentially serious stuff there.

What is white matter on the brain used for?

What is white matter on the brain used for?

White matter: "white matter" refers to the nerve fibers that facilitate communication between nerve cells -- along with myelin, a fatty sheath that covers the them. White matter is below the surface layer of the brain, and can be followed all the way down the spinal cord. Strokes can injure these areas; some people have cognitive changes as well as physical symptoms afterwards.

What is the white matter of the brain used for?

Communication: "white matter" refers to the nerve fibers that allow communication between nerve cells -- along with myelin, a fatty sheath that covers the them. Nerve cell bodies are "gray matter." white matter is below the brain's surface layer, and can be followed all the way down the spinal cord. Strokes can injure these areas; some people have cognitive changes as well as physical symptoms afterwards.

What is white matter of the brain and what is grey matter?

What is white matter of the brain and what is grey matter?

White & gray matter: The gray matter in the brain is nerve cell bodies; white matter is the fibers that grow from them. These fibers also have a sheath covering them called "myelin" which is also part of white matter. If white matter is damaged in some way -- by stroke, inflammation, or disease like ms -- it shows up on MRI scans. Gray matter can be damaged also.

What is grey matter and white matter in your brain?

What is grey matter and white matter in your brain?

Description: The central nervous system has white matter which transmits signals from one area of the brain to another (cerebrum and lower brain centers).Involved in how the brain learns. The gray matter is in areas of the brain that involve muscle control, sensory perception such as hearing, speech, vision, emotions and memory.

What happpen if you have a lot of white matter on your brain?

? WHITE MATTER LESION: Am unclear if you are asking about MRI white matter spots, but if that is the case, perhaps there is a question of ms. But these spots could be due to other causes such as migraine, prior head trauma, medicine reactions, prior brain infections, etc. Ask more information from your physician.

Question?: Not sure of your question. Nonetheless if you are asking about your MRI findings, it depends on the context. Suggest you discuss with your ordering physician.

Can there be a way to help a child who has an atrophy of the white matter?

Can there be a way to help a child who has an atrophy of the white matter?

Intensive therapy: Childhood is the only time we grow new brain cells. Intensive physical, speech and occupational therapy are indicated, as are good nutrition with an emphasis on fats for brain growth. Have your neurologist set up an intensive program for your child, and follow it at home too.

What is the function of the white matter in the cuneate and gracile fasciculi?

What is the function of the white matter in the cuneate and gracile fasciculi?

Carries information: The gracile fasciculus carries information from the legs and lower trunk while the more lateral cuneate fasciculus carries information from the upper trunk above T6, and from the arms and the neck.

I am 541. Nonspecific white matter T2 hyperintensities. I was told this was normal. Should I seek a 2nd opinion?

I am 541. Nonspecific white matter T2 hyperintensities. I was told this was normal. Should I seek a 2nd opinion?

Common finding: With regard to obtaining a second opinion, my first question would be why did you have an MRI performed in the first place? Did you review the MRI with your neurologist? Where are the white matter hyperintensities situated? Was the MRI an appropriate study for your condition?

MRI -The distribution and morphology of these white matter lesions are nonspecific - What does this mean,?

MRIs: This is a very common finding on MRIs of the brain, typically neurologists will state they are from past migraines. Not sure why you had the MRI done though, headaches, memory issues, weakness, talk to e doctor who ordered the MRi about the results.

What makes grey matter grey a white matter white? In other words, what is the difference between grey and white matter?

Cells vs. Myelin: Gray matter mostly consists of the cell bodies of neurons, while white matter contains myelinated axons. Axons are like connecting wires, and myelin (which is whitish in color) serves as the insulation. For more details see: http://en. Wikipedia. Org/wiki/grey_matter and http://en. Wikipedia.

Aspirin...: Blood supply to the mentioned areas are compromised. HTN, DM, Vasculitis, Atherosclerosis, Embolism, can be responsible. Starting with aspirin and doing WU is better.
