So later that day I went by her house -- she lives alone and still drives--- a friend of hers was there when I came over and she told her friend --- here she comes---- I came in the door and say hello but it was a little awkward --- she continued to talk about me as if I was not there and gets very agitated when someone else wants to add to the conversation. I left after about 30 minutes after she said someone needs to put her (me) in jail. A lot of verbal abuse from my mother --- to my face ---when friends are visiting her --- for some reason I am the enemy --- she does not trust me and is very paranoid . Help!!!
I would agree with gladimhere. If this is a symptom that came on suddenly it might be a good idea to get her to a Dr. and checked for a UTI.
If the doctor rules out a UTI, she needs a cognitive evaluation, and not the "mini-mental" most family/general practitioners give. She needs to be seen by a geriatric doctor.
My mother was exactly like that before she got seen by a geriatric psych and put on the right meds. Mom told people she had no children at all, so they were surprised to hear from me when we were moving her to an apartment.
She would berate me in the third person while I stood before her and it did not matter who else was in the room. Absolutely no shame whatsoever.
Mom was also like this when I was in high school decades ago. She purposefully tried to embarrass me in front of anyone who might try to strike up a friendship or take me on a date.
Turns out she had untreated bi-polar and some personality disorders. When the dementia was getting worse, it really exacerbated things. Poor women went most of her life without the right medication or therapy. It was rough.
