Still no better news for my cousin but a little clearer on my nanna's situation.
Firstly, she was removed from the nursing home after 1 day because she was too disruptive there - she was walking around all the time, entering other peoples rooms probably coz she had no idea where she was and why she was there!
They took her to a hospital and she's been there for the last few days undergoing tests and being well looked after. They have actually discovered that she has a urinary tract infection which has been known to cause deliriousness in people. HOPEFULLY this is the main problem in her case because she's had it for quite a while and the hospital is the only place that has picked it up. Dad called her today and she seemed a lot better and understood what was going on
Hopefully she'll be able to go back home rather than to a nursing home... she'll just have high maintenance care coming to her house to make sure she is going ok which I think would be a great idea.
