There was a discussion earlier about your LO's not being able to read anymore, and their visual impairment hindering their understanding.
 

The Library of Congress has a program with free audio books for the visually impaired and anyone with Alzheimer's or dementia would be eligible for this.  I started Paul on this program several months after he had his stroke when he could no longer read.   It was easy because we lived within a half an hour from a Library for the Blind, and it was a simple matter of filling out the form, getting it signed by a doctor, and having it sent in.   They supply you with a free reader, and free book cartridges of your favorite authors which arrive in the mail once it is set up.   Paul was never much of a reader, but even now loves to listen (especially at night) to his books.   How much he actually follows them now is in question, but he's usually quiet and immersed in his book.   I've been told to be quiet.

One web page that will get you to the nls site is:

Right now I'm setting up his BARD account so I can download the books onto a flash drive or ipod that can be plugged into the USB drive on the reader.   But it's a great program.   If you're not sure your loved one will be interested, try a few CD's from the local library and play them for them.  I started off with westerns and international intrigue.   This way you'll know whether or not it's worth signing them up for this service.

There are several libraries in each state that you can go to to check it out also.   Go to the web site and it will steer you towards them.   The libraries have the cartridges also, and I've picked some up there when he's gotten low on books.  

Hope this information helps someone.
