Doctor insights on: Demyelination

Demyelination (Overview)

Nerve fibers have a central axon insulated by myelin covering. Demyelination is damage to the myelin, and typically experienced in multiple sclerosis due to an autoimmune attack by lymphocytes, but may be seen also in hereditary leukodystrophies, acute encephalomyelitis, and inflam. Nerve disorders.

What's demyelination disorder?

What's demyelination disorder?

Loss of nerve cover: Myelin acts as an insulation and covers nerves both in central and peripheral nervous systems, and the above term implies loss of myelin. This is often a description of multiple sclerosis, but is seen in the periphery in guillain-barre syndrome and chronic demyelinating immune neuropathies. ...Read more

What is ischemic demyelination?

What is ischemic demyelination?

Lack of blood flow: Causing a loss of myelin in the central nervous system. This condition is most commonly seen in the periventricular white matter in both hemispheres. There appears to be 5 major risk factors for these lesions:
1. Hypertension
2. Hyperlipidemia
3. Diabetes
4. Smoking
5. Family history of stroke

please be evaluated to minimize the risk for stroke and consider antiplatelet therapy if appropriate. ...Read more

What are demyelination diseases other than ms?

What are demyelination diseases other than ms?

See answer below: There are several demyelinating disease in the central nervous system. Among those, adem (acute disseminated encephalomyelitis), nmo (neuro myelitis optica), marburg or fulminant inflammatory demyelinating disease (idd) etc... Seek the help of a neurologist in order to be properly diagnosed and properly treated as treatments vary for these different conditions. ...Read more

Is demyelination related to compartment syndrome?

Is demyelination related to compartment syndrome?

Yes and no: Demyelination refers to damage to a nerve that causes the myelin sheaths (which help conduct electricity faster along nerves) to either shrink or go away entirely, thus affecting the overall ability of the nerve to move signals along its length. Compartment syndrome refers to an acute condition of increased pressure in a confined space, normally the forearm or lower leg. It can injure nerves. ...Read more

Demyelination: Take your disease modifying medications such as Avonex (interferon beta 1a) /copaxone whatever is prescribed. In general patients with ms do better in cold. See your neurologist, there is a lot of things which can help. ...Read more

Multiple sclerosis = demyelination?

Multiple sclerosis = demyelination?

Characteristic: Demyelination refers to damage to the coverings of the nerves in the brain and spinal cord, and is very characteristic of the inflammatory process that occurs in ms. This can also occur in children with hereditary leukodystrophies, and can be associated with acquired neurological disorders. The disease modifying drugs in MS are designed to control demyelination and many work well. ...Read more

Does brain demyelination cause any symptoms?

Does brain demyelination cause any symptoms?

Usually: Most people with demyelinating disease of the brain (ms) do experience any of a wide variety of neurologic symptoms (e.g., visual changes, numbness/tingling, weakness), these may be intermittent. There are certainly cases in which a person has convincing MRI findings of ms but has no objective clinical signs or symptoms, though even these people are likely to develop symptoms at some point. ...Read more

Can a few (13) brain small inactive demyelinations cause symptoms?

Can a few (13) brain small inactive demyelinations cause symptoms?

Yes they can: More important than the number of lesions is what causes the demyelinating lesions. As an example, multiple sclerosis can cause symptoms from old lesions that remain even after the acute inflammatory attack ends. Talk with your neurologist about what to expect with CNS demyelinating disease. Good luck! ...Read more

Wb-band 41 positive, dfm showed spirochetes and gemmas. Syphilis-negative. Can it be Lyme with only band 41 positive? Got inactive demyelination lessions

Wb-band 41 positive, dfm showed spirochetes and gemmas. Syphilis-negative. Can it be Lyme with only band 41 positive? Got inactive demyelination lessions

Possibly- more tests: A 41 band alone could signify lyme but is not enough to make the diagnosis. Unfortunately most labs don't do an adequate WB test- it's crucial to test the highly specific 31 & 34 bands & most labs don't. Ignenex does the best test. See http://www. Ilads.

What can cause brain demyelination besides a demyelinating disease?

What can cause brain demyelination besides a demyelinating disease?

Several: There are hereditary problems called leukodystrophies, toxins such as glue sniffing can damage brain myelin, paraneoplastic events associated with cancers can have some effect, and of course ms as the best known cause. But sometimes, other disorders seem similar and can masquerade. ...Read more

Lyme suspected. Got 10small inactive demyelinations (d).If I take antimicrobials I feel bad. Could it be because I have d? Or is it just bacteria dying?

Lyme suspected. Got 10small inactive demyelinations (d).If I take antimicrobials I feel bad. Could it be because I have d? Or is it just bacteria dying?

Killing Lyme: Jarisch-herxheimer reaction comes from dying spirochetes releasing inflammatory molecules, producing muscle aches, fever, headache, rapid heart rate, and possibly joint pain. Treatment of this reaction is symptomatic, with meds to control fever and pain. It may be short-lived or persist for weeks; work closely with your treating physician in this regard. Good luck! ...Read more

In 2008 I was diagnosis with demyelination dz it had effected my brain @3%. Now as of my last set of tests in feb. 2013 the demyelination dz is at 27%. Why?

Need diagnosis: Not knowing much about you, I would guess that you could possess a form of multiple sclerosis, which is progressing, and you should be taking a specific medication. Do not understand the % terminology, but nonetheless, find a local neurologist, and confirm the etiology, and if indeed ms, this can be well controlled with newer potent agents. You should not delay. Let us know if we can help. ...Read more
