I believe that my grandmother has alzheimers. Her personality is erroding, her housekeeping is poor, her memory is terrible, she struggles to make any decisions herself. She cares for my grandad who is totally dependant on her. I think she may have hit him on a couple of occassions now. She becomes verbally aggressive if any mention of these problems are made and does not acknowledge these problems. My mother cares for my grandparents and is totally devoted. She too refuses to acknowledge these problems and will only put it down to old age. I think she is scared and thinks if the diagnosis is made my grandparents will go into a home and 'rot'. My mother now spends almost all of her time with my grandparents and when she isn't with them takes constant phone calls. I worry about the huge strain I see her under. I want to help but I can't see what I can do. My mother is a strong character and broaching the subject is almost impossible.
