Thanks so much for the replies so far.
Oddly enough, a good friend who works in mental health has mentioned that it depression can often be misdiagnosed for dementia. Sometimes when I speak to her I have felt the same, but then when she totally loses where she is on conversations (especially on the phone) I do think it’s dementia. I understand that she is on various medication. I know it has changed over the last couple of years and that she is also on anti-depressants. This has been a separate issue that she has gone to the GP about. She always feels more upbeat when she is given support and had things explained to her. When she tells me she doesn’t want to be around and that she doesn’t see the point I try and reassure her that that’s the illness, not her. It’s so difficult to hear my mum say that.
When I am home I will find out more about what the AS are doing with her now. I understand that someone will be assigned to come and see her once a week/every two weeks to take her out for coffee, help with shopping etc. She is still able to do many things on her own, feed herself, dress, shower, and go to the local shops. Anything more than that and she needs help.
