Does anyone have experience of the after effects of surgery for someone with dementia? Mum has been advised that she could have a replacement knee. She can’t make her own decision so I am trying to work out the best way forward. She is in a care home so they could help her with physio, but I have read that surgery can exacerbate dementia. It feels like a difficult decision to make, but mum is quite immobile and if surgery increased her mobility that could be a good thing.
