Mum is 95 and has vascular and alzheimer diagnosis. Sometimes when I visit I can see her whole face has changed, difficult to explain and she is verbally and physically aggressive. I try and ignore and reassure her all is ok in a very calm manner. What is the best to do? Leave or stay and take the abuse. I have a theory that when this happens there is something going on in her brain, maybe a small bleed, but some sort of activity relative to her dementia. Mum is in a special dementia nursing care home.
