Susan is now in a similar situation, from doing various arts activities she can now do very little. No drawing, reading, painting, gardening etc.
I cannot make recommendations as it is all down to the individual and one persons likes another will hate. Susan is 'luckier' than your husband as she enjoys the TV, even though I am never too sure how much goes in. She is happy with old favourites of Poirot, Marple and other detective series, comedy like Dad's Army and the News Channels. We now have an HDMI tv hard drive which connects to the TV and holds lots of her favourite TV programmes and films. They can be played at will.
She also is amenable to listening to music from CD's.
She is OK with sitting in silence in the house or garden for some time and I wonder if I think she should be doing things just because that is what would happen in the past
If she did not still like the above I cannot think how she would 'spend' her time.
There is nothing that she actually does now though.
Susan has a person, outreach, from the Alzheimer's Charity in Leeds that comes and takes her out or comes to chat depending on how she is feeling is that something that you already have access to? There is also a council section who do the same thing for 2 hours or even a day where Sue could visit someone in their home, these are charged for though.
