I actually thought that the posterior column findings were likely due to B12 deficiency - "subactue combined degeneration", due to malabsorption, as we see in this pt (. Turns out vitamin E can also cause symptoms which look like subacute combined degeneration: https://www.ncbi.nlm.nih.gov/pubmed/9012278, as does Copper (TIL): https://www.ncbi.nlm.nih.gov/pubmed/15249607

Vitamin E deficiency causes posterior column findings and hemolytic anemia :)

The way I think about it is that essentially, vitamin E is an anti-oxidant. Vitamin E deficiency = LOTS of oxidation, i.e. free radicals, which are toxic to most cells in the body (particularly myelination and RBCs). That's why it can be used with Alzheimer's patients.

B12 would also affect lateral corticospinal tracts, vit E doesn't to my knowledge (b12 deficiency would also present with hyperreflexia but E deficiency just romberg sign, loss of proprioception and touch, ataxia)

Looks like B12 but no megaloblastic anemia = Vitamin E

Fat soluble vitamins are A,D,E,K. So both D & E could be decreased in this pt. But you have to know that Vitamin E deficiency is associated with demyelination & has been associated with posterior column demyelination. Also Vit E can be given with Alzheimer patients as it helps with free radicals..?
