A rather depressing story about a dementia sufferer on Martyn Hooper's blog.
I wonder how many B12 deficient elderly people (and some not so elderly) are suffering dementia and are in care homes when the cause of their dementia might actually be treatable if caught in time.
My personal opinion is that residents should be screened regularly for B12 deficiency and that those not in care homes should have an annual screening for B12 deficiency.
