My husband has got Alzeimers. The last few weeks he has got worse. I have had type 2 diabeties for 15years and it has caused me to have retinopathy and neuropathy.He said to me yesterday that he did not know i had diabetes i was so shocked and upset. He is now saying i am his daughter and our son is only his son.He talks but i have difficulty understanding what he says. I feel heartbroken as I do everything i can to help him even though i am disabled.Is this usual for people with alzeimers to be so nasty.
