Delirium from B12 Deficiency
Readers have asked me to keep letting them know about these cases, so here it is:
A 62 year old woman in Switzerland, strict vegetarian, was found wandering the streets. Her delirium was determined to be vitamin B12 deficiency. She was treated with 1,000 µg injections weekly and within 4 weeks she had regained a stable mental status and returned to full-time work. (1)
It turns out that she had suffered from B12 deficiency on a number of previous occasions but without the neuropsychiatric symptoms. I hope she will start taking B12 and not rely on being found wandering the streets which might not end so well the next time.
