Engagement problem

You are not alone. You describe what I've been dealing with perfectly. Life does return briefly though when around other people. It's hard.

I agree with. @harshedbuzz that you are doing an excellent job meeting her in her world. I went through this with my DH when he lost interest in puzzles, games, etc. and he too had severe aphasia. He never lost his interest in walking and car rides though so I was lucky there and I could get him to watch some television. I could also pull out his old high school yearbook or some picture books (those big coffee table books) we had and look at those pictures with him. If your DW seems content when she’s not doing anything, I wouldn’t worry too much about keeping her engaged. Keep up the things you’re doing and keep talking with her to make her feel comfortable and safe. You’re doing great!

My DW was a talented artist, champion golfer, and avid book reader. During the past couple of years, the painting became more and more naive, then stopped completely but she won't let me get rid of her easel. She will no longer golf with the ladies groups, but will still golf with me however she forgets where her ball is and what club to use. She now pretty much limits her reading to a few pages before she puts the book down and later tells me she has read it. All that remains is the stare and non-stop questions about when we do the next activity. It's a terrible loss and a terrible disease.
