I am thinking of later on when she is at home. Depending on what area the stroke has affected, could you think about what her interests are and find something to help her still be able to do things. For instance, I used to take patients to various clinics and had the RNIB catalogue which was very helpful. One item was very popular and that was larger playing cards with clear colours. We have a gentleman whose sight has got much worse, and could no longer go to the whist drive that he had been with for years. These cards let him go back to the group, taking his cards to whichever table he sat at and they were also easy to pick up. They also had dominoes with raised dots and colours, which again made good gifts. Another possibility is one of these small lamps, with a very good clear lighting and easy to put on, I have seen one where you just push the top of the lamp and it lights. So this might allow her to put on lights where a small switch could be problematical. Again, if her hands are not affected, possibly a grabber could be helpful, to pick things up from the floor. Anything that lets her be a bit more independant and less frustrated.
I dont know how much it would cost or whether you might suggest it to your children more, but if she doesnt have Alexa, that could be very good. It is set up with your internet, if she has that. I cant remember what it is actually called but you have this little round thing set up by someone for you and then you can just say Alexa radio 3 or off or louder or whatever. I find it brilliant, as I do not have to get up and down to change the channels and you can also get it to go onto things like radio 4 extra, all by voice only and you do not have to move from your seat. Then at least she can choose what she wants to listen to, without having to ask other people to do it for her. A much smaller thing might be to get her some essential oils, such as lavender and rose . If she is able to have a bath they can make it lovely and soothing to add tot hem, or they can be used for massage oils and it may help to make things a little better for her, but just the pleasure of someone stroking and touching her with these lovely smells could be enjoyable, as I feel we do not always get the kind of pleasurable contact touching as we get older. Hope this is of some help
