People 'acting out' dementia...showing us what they think having dementia is, setting up scenes like 'Oh Mum, I'm really sorry I forgot your birthday again!"
Or in a shop "I'm so sorry I gave you the wrong change, I forgot to count it properly!"
That's maybe a very very early stage of dementia, but if they think that's all it is they're very deluded. It can change your entire personality.
Why bother putting millions of elderly people in care homes costing thousands a week, as they simply forgot their relative's birthday..
