Hello - my mum has been on Exelon patch, Risperidone and Mirtazapine for 3 weeks after being hospitalised due to delerium. She has improved but still has problems recognising Dad. I'm having trouble finding information on what is happening and how to cope. Mum will have episodes of thinking that there are people in the house. She also will suddenly be unable to recognise Dad. She says he is similar to dad but doesn't know him. The only thing that works is for Dad to leave the room and when he returns I say "hello dad" and mum remembers him. She will be fine then. I have read about photo albums and dad wearing a name tag, which I don't think will work as it will make her feel stupid. When mum is out of this episode I can explain what is happening to her and she understands so we are walking a very fine line. Does anyone have any experience with this particular issue? I would appreciate any advice.
