I really need some advice. I have a very difficult mother who alternates between over the top lovey lovey to frankly spiteful and nasty. We have never got on, but in the last year or two I have begun to wonder if she really is getting dementia. She seems to be suddenly suspicious of the motives of others, rants on about a subject at great length, conducts an hour long monotonous dirge about random subjects which are loosely weaved together. At other times she can seem quite rational . She seems to believe that I am resentful of my sister, and misrepresents what I have said or believe about my sister amongst many other subjects.
Recently she has been making some very strange and unkind remarks about my OH who has always tried to be kind and pleasant to her. She will now come out with outrageously rude and unkind statements about him and seems to believe I have been twisted by him. I dread seeing her and hardly ever visit, but now I just don't want to see her at all. She can't be reasoned with as she isn't rational and interprets any attempts I make to reason with her as deluded attacks because I have some problem or am 'too sensitive'. I feel so alone as my sister always takes her side and isn't interested in what was said or happened from my perspective.
I appreciate lots of elderly women are like this, but because I have never had a good or positive relationship with her I just don't have any reserves to fall back upon.
I don't know what to do. She is nearly 88.
