Been checked for peripheral neurophy and that has been ruled out. As much I don't want it to be MS if it is then it's early stages.
Did you get diagonosed early? Thank you for the information.
I urge you to read the book,
Could It Be B12? An Epidemic of Misdiagnoses by Sally M. Pacholok, RN, BSN, and Jeffrey J. Stuart, D.O. (This may be available at your library.):
http://b12awareness.org/could-it-be-b12 ... diagnoses/
On page 11:
There is much controversy as to what constitutes a normal result for this test [serum vitamin B12 test]. Because of this controversy, this test is often used in conjunction with other markers of B12 deficiency (MMA, Hcy, and more recently the HoloTc).
… We believe that the "normal" serum B12 threshold needs to be raised from 200 pg/mL to at least 450 pg/mL because deficiencies begin to appear in the cerebral spinal fluid (CSF) below 550 pg/mL.
At this time, we believe normal serum B12 levels should be greater than 550 pg/mL.…
We commonly see patients with clinical signs of B12 deficiency who are not being tested. Others who are being tested are not being treated because their serum B12 falls in the gray zone [between 200 pg/mL and 450 pg/mL]. This error results in delayed diagnosis and an increased incidence of injury.
According to these authors, your B12 test result of 400 pg/mL falls in the "gray zone" and may not be optimal for you.
Elsewhere on page 11, these authors state: “For brain and nervous system health and prevention of disease in older adults, serum B12 levels should be maintained near or above 1000 pg/mL.”
page 253: “Humans and other mammals are all born with serum levels of about 2,000 pg/ml, which decline gradually throughout life.” (J.V. Dommisse)
In Japan, a B12 level below 500 is considered a deficiency and is treated.
Meat, poultry, fish, eggs, cheese, dairy – animal-based foods – are the only dietary sources of B12; it sounds like your intake is adequate, but the pathway to the cells (where it is needed) is complicated and can be disrupted in more than a dozen places. It is possible to have a functional deficiency in the cells/tissues.
You have had the serum B12 test. Thorough, initial testing to rule out a possible B12 deficiency should have included these 3 tests: a serum homocysteine test, a methylmalonic acid test, and an RBC (red blood cell) folate test. Do you have the number results for these tests?
As for my personal MS history, I was diagnosed with MS more than two years after symptoms began. (However, like many other MS patients, in retrospect, I recall symptoms much earlier in life that I simply dismissed as something else.)
