My Grandad is 87 and has had a diagnosis of dementia for a number of years now. He has started to decline rapidly and has now reached the point where he has talked about different ways he could kill himself. He is very detailed in how he would do it and has a number of ways in mind. He has also, however, explained that it wouldn't be fair to whoever found him, or if he jumped in front of a train or bus the driver might get in trouble and they would have to live with killing him so it wouldn't be fair.
He gets very emotional and is fully aware that his brain is declining and that he will need more and more care which is the thing that makes me think his threats are much more than that and he is trying to prepare us.
He doesn't know who we are anymore but he does know he sees us often so we must be significant.
I don't know what to say to him, how to respond and I know that the last thing he would ever have wanted is to forget us or need care and not be able to perform basic functions like going to the toilet unaided.
Any advice would be very greatfully received.
