> One theory of why nerve problems occur in B12 deficiency is from a lack
> of methionine (from B12 not converting Hcy back into methionine) which
> creates a lack of S-adenosylmethionine (SAM).35 SAM is required for the
> production of phosphatidylcholine36 which is part of the myelin (the
> fatty material that insulates many nerves). Phosphatidylcholine improves
> nerve transmission.36

> Another theory is that the altered nerve function of B12 deficiency is
> possibly due to the body's inability to convert methylmalonyl-CoA (a 3
> carbon molecule) to succinyl-CoA (a 4 carbon molecule). This inability
> results in a build up of propionyl-CoA (a 3 carbon molecule). Fatty
> acids are normally made by adding 2 carbons at a time to an even
> numbered carbon molecule. In an overabundance of 3 carbon molecules,
> large amounts of unusual 15-carbon and 17-carbon fatty acids could be
> produced and incorporated into nerve sheets, causing altered nerve
> function.103

> Early Signs of B12 Deficiency
> According to Crane et al.18 (1994, USA), the usual vegan patient has no
> clinical symptoms or signs of inadequate B12. Early manifestations are
> unusual fatigue, faulty digestion (no appetite or nausea) and loss of
> menstruation. Other symptoms are nervousness, numbness and tingling of
> the hands and feet, mild depression, striking behavioral changes,
> paranoia, hyperactive reflexes, fever of unknown origin,18 frequent
> upper respiratory infections,19 impotence, impaired memory,49
> infertility,55 sore tongue, and diarrhea.60"
