Can grey matter regenerate?

Can grey matter regenerate?

No: Neural cells after fetal development do not divide and therefore regeneration is not possible. There is a molecular switch involved and scientists are working on ways to turn it off. ...Read more

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

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 grey matter heterotopia?

What is grey matter heterotopia?

Neurologic Disorder: Gray matter heterotopia is a neurologic condition that is often associated with seizures in which bits of gray matter are scattered in areas of the brain they shouldn’t be (sometimes just one area). ...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

Porn will really destroy the grey matter from my brain?

Porn will really destroy the grey matter from my brain?

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 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 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

Bilateral frontal lobe subcortical white matter showing evidence of small vessel ischemic changes. Is this serious?

NONSPECIFIC : Although the films were read as suggesting ischemia, location might also suggest prior head trauma, congenital lesions of no consequence, genetic or hereditary issues, even underlying inflammatory condition. This is only "serious", if clinically you are having stroke symptoms or you possess uncontrolled blood pressure or elevation of blood lipids. Likely quite non-diagnostic. ...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

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

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

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

MRI Brain/IAC for hearing loss. few scattered foci high signal in subcortical whites matter likely small vessel ischemic change. could this be MS?

MRI Brain/IAC for hearing loss. few scattered foci high signal in subcortical whites matter likely small vessel ischemic change. could this be MS?

See neurologist : While matters changes on brain imaging is part of the diagnosis of MS, but can well have other causes. You did not mention any of the visual, balance, coordination symptoms that generally begin the diagnostic work up. Diagnosing from an MRI itself is it good medicine. If you have concerns on their significance, see a neurologist for an exam and correct diagnosis. ...Read more
