Up till a few months ago it was memory lapses and struggles using home appliances, but recently I arrived her at the house to find her looking very stressed and telling me an impossible story about something that I was able to prove to her had not happened. Just this morning she phoned me stressed about me having 'rearranged' a room in her house and she couldn't find some xmas presents she left there - I had moved some furniture that room a month ago, but there were certainly never any xmas presents there (they are all in a different room).
A few days ago I was talking about taking my daughter to the natural history museum, and I asked if she remembered taking me when I was a boy, and she asked "where did you live when you were a boy?", she at least immediately realised what she'd just said and corrected herself (slightly embarrassed) "of course, you were living with me and dad".
I'm about to get quotes on a deferred care annuity for my mother (where you pay a lump sum, and then get care home fees paid for as long as the person lives), I was thinking to defer payments for two years (to get a cheaper quote) on the assumption that she can manage at home with just a single daily care visit for now, but wondering now if I need to plan for full-time care being needed sooner.
