You've got that right.
My mom has dementia, my Aunt had Alzheimer's, neither is good. It is a disease and personalities do change drastically.
Although most people even hate to think of it, if it's possible, having someone in some type of nursing home or even day care is way better, not only for them but for the caregivers. Taking care of elderly is way harder than taking care of kids!
My mom is way happier and get much better care in a nursing/rehabilitation home than I what could give her. I know, I tried. When it got to where I could not leave her for more than an hour or two, that was it. Anyway, it really doesn't matter anymore, she has both short and long term memory loss. Sometimes she knows who I am, but not always.
Sometimes I'm her daughter, or her sister or her niece..<G>
Funny, she'd sit up late at night, I'd ask her why... Oh, she was waiting for her mother to get home. At that time she was already 94! but would never admit to it. She'll be 97 this June. Just don't tell her, she gets mad if anyone says she's old! <LOL>
