Granniesunite, I’m so sorry to hear that your husband has Alzheimer’s Disease, it is a horrid and cruel illness.
My mother had it, I used to flick through fashion magazines with her, as fashion was her career background, commenting on the look, asking her if she thought the colour was nice, simple questions. If she looked a bit confused I’d move on to a different question.
Perhaps some magazines related to your husbands career or hobbies, easier to flick through than to try to read a book.
I did sing with her quite a lot and even in the later stages when she didn’t even know me she still remembered all the lyrics to many old wartime songs. Probably more sixties and seventies music in your case.
Singing always cheered her and we’d often laugh if I got the words muddled.
I did find that trying to get her to remember things that she couldn’t would distress her. My sister often did this, almost as a test of how well or badly she was doing.
Same sister now has the disease herself and is in a home. I haven’t been able to visit due to restrictions but hope to see her soon.
There are many on here with experience and greater knowledge. The suggestions so far seem very helpful. I agree wholeheartedly with this who suggest you say YES to all help offered, otherwise it can be a long and lonely road. Good luck.
