Sorry to hear about your granny,.........there are drugs(Aricept, here in the States) that will slow the progression and maybe show some improvement. My Mom has Alzheimer's and was given Aricept and has gotten a bit better but the progression has slowed considerably. My wife's a closet wiccian (don't ask, I don't),.....I'll check with her.
