Hi @way2jackie and @crankyyankee, your situations sound similar to ours. My husband was diagnosed with Alzheimer's in 2017. He's had a good disposition throughout, and is extremely forgetful, but still articulate.
He gets up very early to rummage in the fridge - so I always have muffins on hand to eat and yogurt, then he goes back to bed, often for most of the morning, unless there's something going on in the neighborhood he can watch.
I was concerned about his wanting to stay in bed so much. The neurologist told me that's part of the disease. Recently, the geratrician told me that the brain needs recharging, like a battery that's lost energy.
My husband has no interest in going to a day program.
I can get him out to walk, and if it's raining, he'll do some exercises with me in the house. We have a soft plastic ball, that's large, and he'll play catch for a while. That was something the OT did with him after he broke his hip.
Maybe when your husband's OT sessions end you can get him to do similar exercises with you or have someone in once a week.
Once in a while, my husband will play Scrabble with me. I play often by myself and he'll visit the board to check out the words.
I've also purchased a number of "Adult" jigsaw puzzles that he'll work on. Lately, he does them on his own while I cook. I help him out with a piece once in a while.
To keep him engaged, I ask him to help me with chores around the house which he does willingly. He also enjoys going out to lunch, which I'm going to try to do more often.
In the beginning it was hard for me to accept all the time he wanted to rest, but I understand now that he needs it. And he is very content for which I am thankful.
Best to you both.
