My mom is in her late 70s, has issues with dementia (though not formally diagnosed) because she is stubborn and cheap. She has signs of Narcissistic Personality Disorder and is extremely resentful of any family. She's recently told me not to be in contact with her. (I'm letting her be for a while.) But, I swear sometimes it's like I'm dealing with a very helpless and wildly imaginative (and not always in a good way) 5-year-old and other times it's like I'm dealing with a very angry, spiteful, paranoid old woman. It's very rare to have a day where it's just "mom."
