Whit Matter On The Brain
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. ...Read more
Many causes: White matter lesions can be caused by a very wide range of things, ranging from toxic exposure to multiple sclerosis to hypertension to chronic migraines. A neurologist can help you put the imaging findings into perspective with the rest of your clinical picture, and guide further workup and treatment as needed. ...Read more
Nonspecific: Scattered white spots confined to the white matter of the brain are fairly common and not specific for a certain disease. White spots in a person less than 50 yrs. Old, however, are usually abnormal and may be seen with multiple sclerosis among many other entities. As one ages, these are more likely due to tiny arterial blockages and are fairly common in people over 70 yrs. Old. ...Read moreSee 1 more doctor answer

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. ...Read more
I'll Try: You know that Hannibal movie where the guy's head was open you see brain hat you see is the grey matter. If you cut deep into a person's brain it looks more white, hence, the white matter. The fancy explanation, grey matter are the cell bodies and white matter are the axons (nerve wires). Your brain is arranged in a way where it just so happens to appear the way you see. ?W ...Read more
What does it mean when the Grey matter in the brain is leaking into the white matter of the brain? And what kind of effects can it have?
Which planet we on?: Here on Earth there are no human beings who leak Grey matter into white matter. Do you have a report of some sort that you're looking at & trying to interpret? The only thing I can think of that would have any remote significance to what you're saying is called "heterotopia" which refers to islands of gray matter within white matter territory. Seizures are known to occur as a main manifestation. ...Read more
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. ...Read more
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. ...Read more
My brain MRI says one small area of increased signal on flair images in the right parietal white matter- what does this mean?
May be nothing or?: Your clinical history- the reason you had the MRI- may be a clue. Many brains show one small area of flair signal. These are often due to headaches, head injuries, high blood pressure, changes in blood flow, etc. They are not by themselves an indicator of much. If you had many of these, and symptoms of MS, they could be related. A single small area though is not alarming. ...Read more
What is no focal signal changes on T2 images of the of the brain on a MRI report of the brain? Does it mean cerebral microbleeds and hypointensity T2?
No focal: signal changes generally means that there is no abnormality. ...Read more
Porn changes brains: Hi R, One study found smaller gray matter volume and diminished communication between the two halves of the brain in high porn users. Excessive porn users also require more stimulation to get motivated, so the bottom line is, anything in excess is likely to have problems associated with it. Moderation is key. Hope this is helpful. Take good care ...Read more
What does the no focal signal changes on T2 images of the remainder of the brain mean on a MRI report of the brain?
Normal: This is unremarkable and nothing to worry about. ...Read more
It depends....: How white, grey or black signal on an MRI scan is interpreted depends on the type of sequence that spot appears in. So without knowing the sequence, i can only guess. If these are scattered black dots they could represent small foci of old hemorrhage or iron deposition. If it is a bigger spot it could represent a fluid collection. I really would have to see the images to give you an answer. ...Read more
