Ma, 85 diagnosed mixed dementia in 2010 (but I think she's had this condition since the turn of the century at least) has just asked me 'how did I get here?'. She didn't recognise our house (we've been here 10 years) and had no idea 'why' she was here. She has totally forgotten my Dad to whom she was married for 50 years and for whom she moved to England from overseas. I showed her pictures of him: "What? That old man?" He died in 2012. She thought our house was a hospital. I thought, good grief, if any hospital looked like our house Panorama would be making an undercover programme about it! She's been confused about where she is previously but this feels different. Anybody else recognise this sort of confusion? Can it be temporary or does it signal a new decline?
