Grandma lately keeps bringing up that she is living in a prostitution house. Does anyone else have this problem?

It could mean many different things. Either she did live in such a place once and she is mixed up about time, or she has dementia. My mother has dementia and her "loop" thinking is that two of her distant relatives are contacting her all the time, wanting to visit and she knows they are after her money. It isn't true, they aren't writing or calling, but she can't get it out of her head and it keeps going around and around. If your grandmother is not upset about her imagined living in a "prostitution house" I'd go along with her and let her imagination go wild if it makes her happy.

My grandfather saw dancing girls late in his kidney failure. He would chuckle when they were in the living room and say " Don't tell your grandmother."

Yes, it sounds like the same type delusion that many of our parents have. captain's comments were about his mother and mine. It would be interesting if your grandmother's delusion was based on history. That would be rich. I don't know why people with dementia often pick one thing to dwell on. In my mother's case, her delusion is built on work that we had done on the floor, so it does have a little history that became distorted in her mind. I believe that, in her case, she was looking around for something to blame for the way she felt. The work on the house was chosen as the culprit, I guess. It was more settling for her to think the work was wrong than that she was getting older with dementia.

Does living in a house of ill repute cause your grandmother any discomfort? I would see if I could learn some history, as the others said.

if your hor house was sitting on stilts and had no ceilings a couple others of us could relate but as it stands i dont have a clue.

Anyone running around the house in their nightshirts? Granddaughters dressed in short shorts? Men visiting, even if they are just working in the building for example. Could she be misinterpreting the environment?

She says she's living (like now?) in a prostitution house? If that's the case, it sounds like she's got dementia. If she's talking about her childhood, then like the other commenters have said, ask her for more info. A lot of people back then lived in boarding houses, or had a room in a house owned by someone else. Maybe that's what she's referencing.

It's probably just the dementia...Or, this could get interesting!

During the Great Depression, people lived wherever they could. It's very possible she was born in a brothel or lived near one. I would ask her for more details, you may be onto some juicy history that has long been hidden.
