Does hyperintense focus in white matter mean brain cancer?

Does hyperintense focus in white matter mean brain cancer?

Unlikely: It would be unusual for a focal hyperintense focus in white matter to be a tumor; however, one needs to better understand what the specific sequence used on MRI (T1, T2, FLAIR, T* etc) to be more informative. ...Read more

White Matter (Definition)

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 ...Read more

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. ...Read more

What does mulitple(atlest 10)tiny t2/flair hyperintense foci in cerebral white matter, predominantly subcortical and deep white matter implies?

What does mulitple(atlest 10)tiny t2/flair hyperintense foci in cerebral white matter, predominantly subcortical and deep white matter implies?

See your doctor: Hyperintense white matter signals may mean nothing clinically or could be related to a host of diagnoses, including multiple sclerosis, autoimmune, etc. It has to be correlated to an exam and other testing to make any sense of it, a lot of times it is an incidental finding and means very little clinically. Your doctor will help you understand what this report means to you clinically. ...Read more

What is white matter in the brain?

What is white matter in the brain?

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

What does 2 hyperintense foci in the right frontal white matter and 1 hyperintense focus in the left frontal white matter mean? migraine 20yo

What does 2 hyperintense foci in the right frontal white matter and 1 hyperintense  
focus in the left frontal  
white matter mean? migraine 20yo

Non-specific finding: The findings you list are non-specific but are frequently seen in people with a history of migraines. It may be advisable to meet with a neurologist who can go over your history, review the reason the MRI was obtained in the first place and perform a detailed neurological exam to determine if further testing is required. ...Read more

Bilateral frontal lobe subcortical white matter showing evidence of small vessel ischemic changes. What does this mean?

Bilateral frontal lobe subcortical white matter showing evidence of small vessel ischemic changes. What does this mean?

Subcortical ischemia: This translates to changes in the smaller blood vessels that lead to loss of blood flow to the area and then scarring. Somewhat like a small silent stroke and frequently seen in people with migraines. The opinions about this have swayed from very worried, to common and mundane and more recently back to looking to stop the damage (help the blood flow, oxygen and glucose status optimize). ...Read more

What kind of activities stimulate gray matter in the brain? What about white matter?

What kind of activities stimulate gray matter in the brain? What about white matter?

Life and effort: There is no actual need for costly and elaborate programs to improve brain capacity (presuming non-disease state). Pay attention to what is around you. Think about it. Analyze it. Dig through the endless resources of the internet. Challenge yourself with new ideas and examine your beliefs. Have intelligent conversations. Intentionally vary your activity. Get physical exercise. Live fully! ...Read more

My MRI found multiple frontal punctate subcortical white matter foci appreciated notable in the frontal lobes. What does this mean?

My MRI found  multiple frontal punctate subcortical white matter foci appreciated notable in the frontal lobes. What does this mean?

Sign of Age: You often see these as we get older, especially if you have high blood pressure and/or high cholesterol. The small blood vessels in the brain, like everywhere in the body, can get clogged with cholesterol, especially if you have high blood pressure and diabetes which makes the vessels less elastic. ...Read more

What does the results few tiny nonenhancing T2/FLAIR signal foci within the 
subcortical frontal & right temporal white matter  of an MRI brain scan?

Blood vessels: Most likely would be blood vessels. But that also depends on why you had the test in the first place. Usually in young people we don't see too many of these white or bright spots. As we get older they show up. Ask your doctor to explain the results on general ...Read more

Can a brain MRI detect nonspecific supratentorial white matter disease?

Can a brain MRI detect nonspecific supratentorial white matter disease?

Yes: Nonspecific white matter disease may be seen in individuals with migraine headache, can be post infectious or can be a result of hypertension and high cholesterol. At times MRI with administration of contrast is recommended to better characterize these lesions. ...Read more

What is deep white matter in the brain?

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

Does masturbation cause the white matter in brain reduces?

Does masturbation cause the white matter in brain reduces?

Yes, in time...: If masturbation becomes a compulsion of life, it overdrives the pleasure-seeking cerebral cortex in time leading to its suppression and shrinkage. More detail on its related subjects? Go to http://www.lifeissues.net/writers/hil/hil_01brain.html. Besides, treat compulsive masturbation as a drug addiction from overindulgence and obsession as elaborated in http://formefirst.com/eNewsletter05.html. ...Read more

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

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.Org/wiki/white_matter. ...Read more

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. ...Read more
