Is this inevitable?

On an online forum, someone who, along with other family members, is looking after Mum who has dementia, is asking whether it is inevitable that she will cease to recognise them at some stage.

My thoughts are that almost nothing is inevitable, except death - and the person we are caring for might die today, as might we.

I've always been a bit anxious so if I allow myself I can think of any number of horrific scenarios. You don't even need to imagine them these days, you can if you wish read blow-by-blow accounts of carers' experiences in real time.

What we have to try and do is, as people keep repeating, to live in the moment, like so many of the people we're caring for do.

I actually find the thought that everyone is different and everything is unpredictable a consolation.  How would anyone cope if all people with dementia followed exactly the same path, on the same sort of timetable, via a series of known and minutely documented horrors towards their extinction?

And, by the way, it certainly isn't inevitable that Mum will fail to recognise her family.
