My mom is in the later stage of dementia she is up 36 hours straight at times and talks to people I can't see. She doesn't know that I am their she is on hospice now she has had many bladder infections that have the same symptom I have asked hospice to do a test on her but they say its just dementia and refuse. Has anyone gone through this and is it normal? She just talks and yells. To people that have past she's in her own world talking to them and has no idea of whats going on around her it's very sad I would not want anything to happen and feel I could have done more if they did the test and it was negative then I know that their was nothing I could have done God bless.
