My best friend since childhood just lost her mother to Alzheimer's Disease. She had been in a nursing home for over a year, and hadn't recognized family in about that long. Sounds as though she took a bad fall, injured her head, slipped into a coma, and died five days later. Apparently her last MRI had been very bad.

I'll soon be posting some information about the diagnostic differentials for dementia due to B12 deficiency and Alzheimer's. There is a lot of info out there. We used to have a thread about it on the PN forum. I mostly post on the Gluten Sensitivity/Celiac Disease forum.
