Two ideas that were helpful for my mother. I got the simplest iPod and headphones and loaded songs from the 30's, 40's and 50's, the years she remembered in her late stage AD. This was not simply entertainment. It would often stimulate her enough that she would eat a meal, rather than not eat at all. And I replaced the chairs in her room (long term care facility) with a small, two-seat sofa. During visits, that let us sit side by side, sharing a little body warmth, holding hands and sometimes doing nothing else. Everyone needs human contact especially when others means of communication are slipping away. This was a simple way to enhance it.
