- QUESTION: Could you please discuss the meaning of the word "Demilonization"
- as it refers to nerve disease. Naturally we have a specific person in mind,
- but if we can just understand this last piece of information, we are sure we
- can put the whole story into place. Thank you.

- ANSWER: Sometimes it is the last piece of the puzzle that makes the picture
- clear. "Demyelination" is a process we see in nerve disease where the
- insulating sheath that covers many nerve fibers and which is called "myelin"
- is either injured or degenerates because of lack of oxygen, toxic agents, or
- metabolic disorders. Myelin is composed of layers made of lipoprotein (fats
- and protein combination), and promotes the transmission of the electrical
- nervous impulses along the axon of the nerve. When the myelin degenerates,
- the axon dies, and the impulses can no longer prompt muscles to work or carry
- the sensory sensations to the brain. Some types of metabolic congenital
- disease, such as Tay-Sachs, Niemann-Pick and Gaucher's Disease, affect the
- developing myelin sheath, causing widespread neurological disease. When
- demyelination occurs in the central nervous system as a basic cause of several
- diseases, they are known as primary demyelinating disease. Multiple sclerosis
- is perhaps the most common of these diseases. In many cases of these
- disorders, the myelin can regenerate and repair itself with the return of
- nerve function or remission. Unfortunately, degeneration can recur with the
- pattern of disease, exacerbation and remission being common. It is difficult
- to know from your letter exactly what you wish to know, but I hope this
- information is helpful.
