This is my first post. My dad has been having memory problems and a host of other symptoms which, to me, point to B12 deficiency.
He has tinnitus, diarhea, lack of appetite and weight loss, tiredness, memory problems, cognitive decline.
He has recently had a lot of tests including CT scan and a Vitamin B12 test (which apparently was in 'normal range' and cancer ruled out. They are now beginning investigations for dementia.
I feel that B12 deficiency is the problem and am at standstill with trying to find help for him. I have read that a ridiculously high proportion of people with Alzheimers actually had a B12 deficiency.
I don't know where to turn.
I know this is a PA group but I know you are also well versed on this.
Which test is it we buy from 23andme to test for Vit B12 deficiency? Would anyone be able to help me interpret the results?
