Retardation of myelination due to dietary vitamin B12 deficiency:
cranial MRI findings.
Lövblad K, Ramelli G, Remonda L, Nirkko AC, Ozdoba C, Schroth G.
"Vitamin B12 deficiency is known to be associated with signs of
demyelination, usually in the spinal cord. Lack of vitamin B12 in the
maternal diet during pregnancy has been shown to cause severe
retardation of myelination in the nervous system. ... It was concluded
that this myelination retardation was due to insufficient intake of
vitamin B12 and vitamin B12 therapy was instituted. The patient
responded well with improvement of clinical and imaging
abnormalities."

Subacute combined degeneration of the spinal cord: easy diagnosis,
effective treatment
Jongen JC, Koehler PJ, Franke CL.
"Subacute combined degeneration of the spinal cord is a neurological
disease based on vitamin B12 deficiency. ... Vitamin B12 deficiency
can cause subacute combined degeneration of the cord by interfering
with myelin synthesis. As vitamin B12 deficiency is caused by
malabsorption in the gastrointestinal tract, oral supplementation is
insufficient."

Vitamin B12 and its relationship to age of onset of multiple
sclerosis.
Sandyk R, Awerbuch GI.
"since vitamin B12 is required for the formation of myelin and for
immune mechanisms, we propose that its deficiency in MS is of critical
pathogenetic significance."

Vitamin B12, demyelination, remyelination and repair in multiple
sclerosis.
Miller A, Korem M, Almog R, Galboiz Y.
"Low or decreased levels of vitamin B12 have been demonstrated in MS
patients. Moreover, recent studies suggest that vitamin B12, in
addition to its known role as a co-factor in myelin formation, has
important immunomodulatory and neurotrophic effects."


Jpn J Ophthalmol. 2000 May;44(3):320.
The eye and nutrition
Amemiya T.
"Vitamin B(12) deficiency reduced nerve fibers in the nerve fiber
layer of the retina. ... Deficiencies of Zn, Cu, Mn, and vitamins A,
B(12), and E induced degeneration and disappearance of myelin lamellae
in the myelinated optic nerve fibers."
