Someone else mentioned cns/csf deficiency and I tried to google it but it was a little over my head. I didn't really understand it. About 2 years ago I was found to be b12 deficient, my level was 209. Because of blurred vison in spots, the dr. ordered an MRI. I came back showing multiple non-enhancing subcortical and deep white matter punctate hyperintensities in both hemisphers. I than had a lumbar puncture to rule out MS (no MS). I had an ANA test show positive 1:80 homogeneous pattern (ref range <1:40) Gliadin IGG AB slightly high at 68.2 (ref range <45) and Anti pareital cell pos. intrinsic factor neg. Alot of other antibody test where done, all were neg. Lyme come up 2 titers pos. so that test was considered negative as well.

I think my symptoms are probabley all from malabsorbtion issue as you mentioned. That makes the most sense.
