My mother is a sufferer - it rapidly got worse during the winter - she wasn't too bad last September, but this April she had given up on just about everything - cleaning, bathing, putting the trash out, etc. etc.
Basically she now just eats and sleeps - she can't even comprehend the cooking instructions of ready meals
I live a long way away from her and only see her a few times a year
She won't accept that there is anything wrong with her
She's destined for a nursing home - just a matter of time now before the local council take action as they know she's not taking care of herself, and has been brought home twice by the police
