Recently, my Mom with dementia has been telling me she hears people walking around upstairs in her home, but she is not frightened by this. Advice?

I would discuss it with her doctor. Usually, any change in mental status is cause to investigate. She could have an infection or something else causing it. I'd also make sure there is no actual man who is coming over.

If it is an hallucination due to dementia, you can discuss it with her doctor. She may not be able to live alone anymore and she may want to treat it with medications. Although the present hallucination does not disturb her, others could and it could be very distressful for her. I would anticipate this before it happens.

Yes, check with her doctor.

Dementia can include auditory hallucinations. If that's what this is and this doesn't disturb her it is not necessary to treat it.

It may also be a misinterpretation of real noises. Something in my kitchen makes a noise a lot like the door opening from the garage. I've often expected it to be followed by one of my borders coming in, but I've learned that it is the fridge recycling (or something). She may be hearing real noises and just guessing wrong about what they are.

But do discuss it with her doctor. It could be something else. Better safe than sorry.

Visual and auditory hallucinations are a hallmark of dementias, especially Lewy Body Dementia. Your mom should have another complete neurological evaluation.
My mom also insisted that various workers were coming into her home, through a "secret stairwell" in her bedroom closet. Mom also sees "schoolchildren skipping in the living room," and "brown-spotted mice in the kitchen."
Mom would get very upset if we would tell her she was dreaming or hallucinating. So now, instead, we say, "I swept out the kitchen mice with a broom, and called the exterminator!" or "I just double-checked the bedroom closet with my 'MagLight'...everything has been locked and boarded up for the night."
Mom's neurologist did talk to her at some length, to make sure her hallucinations were not scary ones.
One has to adjust to the patient's new reality, as they will never, sadly, be coming back to ours.

My mother has Lewy body dementia and has been in a NH for almost 3 years. She had a phantom cat for some time - fell out of her wheelchair trying to pet it and taken to ER ... I bought her some stuffed animals and that cured that. Then she's worried that when my father comes to visit and stay over night (he's been gone 16 years) the staff won't know who he is. Then there's the man who sleeps under her bed every night who she doesn't mind at all ... in 6" of space?

At close to 90 her mind is away with the fairies. She keeps trying to get out of bed or her wheelchair by herself and falls ... just this last week she was taken to the ER and ended up with a black eye and 8 stitches above that eye. Alarm on her bed but by the time it goes off she's on the floor. One or two more falls, banging her head, after numerous strokes, it will be the end of her. Wonderful though the staff are, there's nothing that can be done.

My mom would have auditory hallucinations, and the Dr put her on risperdole. It really helped. Although she was convinced she was hearing these voices, she wasn't overly concerned about it other then to try to convince everyone else of it. She would just listen and talk to them. I was horrified, my mother was losing her mind and there was nothing I could do about it. Like I said, the drugs helped.

I agree with posts. Call her MD. could be a urinary tract infection, effects of meds, etc. Best to find out

I aggregate (collect these tidbits on
"Dave Mainwaring's Knowledge Network" )

Sunrise Syndrome,(sun?riz) a condition in which a person with Alzheimer's wakes up rising in the morning and their mind is filled with delusions which include include beliefs about theft, the patient's house not being their home, a spouse is an impostor, belief an intruder is in the house, abandonment, spousal and paranoia, people eavesdropping. Sometimes the person may carry over content of a dream.

AND Call her MD and ask about testing Something has gone wrong and you need to know what.

From your post talking about "her home," it sounds as though mom may be living alone. Doesn't sound like she should be.

My mother thinks someone is in the house at times. I think it's because she is very vulnerable now...and has been a little more scared the last few years. I take care of her now...and assure her that no one is in the house but family...then she drops the subject.

My mother had similar experiences. In the hospital, she became belligerent, then when she pooped the bed up because she had lost her olfactory sense, she couldn't smell the foul odor. Then at the NH, a man jumped out of his bed to assist her (of course, he was a staff member), "he went back to his hotel" (an untruth) and there's a man sleeping in my room on the floor."-another hallucination.
