Patient discussion about myelination

Q. What is Myelin?

A. As part of the nervous system, myelin lines nerve fibers to protect and insulate neurons. Myelin aids in the quick and accurate transmission of electrical current carrying data from one nerve cell to the next. When myelin becomes damaged, the process involves numerous health conditions, including multiple sclerosis.

Dysfunction in the myelin of nerve fibers causes the interruption of smooth delivery of information. Either nerve impulses can be slowed, such that we can't pull our hand away in time to avoid being burned, or mixed up, so we aren't able to determine if a pan is hot in the first place. This is akin to a pet chewing on a wire, causing the device to dysfunction. When problems arise in nerves of the PNS, neuropathy might result, and when injury affects the nerves of the CNS, multiple sclerosis is often diagnosed.

Previous clinical and experimental observations have suggested thatthyroid hormones may be of clinical relevance in MS, because they are critical for CNS myelination and may play an important role in remyelination; whether thyroid hormones influence the remyelinating ability of oligodendrocyte precursors in especially early (fresh) demyelinating MS lesions is an important yet unresolved aspect of the role of the endocrine system on MS (25).
For example, concentrations of choline (Cho), believed to be a marker of myelination and cell membrane stability, 7V-acetyl aspartate (NAA), a neuronal or axonal marker, and creatine (Cr), a marker of metabolic activity, can be measured either in absolute concentration values or as ratios relative to each other.
