Is there anything I can do to convince my mother that no one is stealing from her?

You are not going to convince your mother of anything . She can not be reasoned with due to her dementia .

I read your profile . I’m sorry you have recently lost your son . And between that and your mother’s illness it’s understandable that this is so difficult .

You’ve had so much on your mind .

Do you have POA for your mother ? Or does another family member ?

Because what you described of your mother coming across the yard to your house and trying to hit you over the head with tools is an alarm sounding that your mother needs to be placed in memory care .

POA if invoked can have your mother placed in memory care .

The other point is that you were not safe . If that happens again where you or someone in your home is unsafe due to your mother call 911. Tell them Mom is agitated . A UTI could make Mom act out worse . They will take Mom to the hospital . From there you can speak to the social worker and they can help place Mom in a facility .

You would need to tell them she is violent , you are not safe , you can not take care of your mother any longer . And that it’s an “ unsafe discharge “ because your mother should not be living alone . Use the words “ unsafe discharge “ , because they will try to get you to take Mom home at first . Do not pick Mom up from the hospital . Do not move in with Mom or move her in with you .

If your mother ends up in the hospital for any reason at all . Same as above do not take her home , get her placed .

I certainly hope there are no guns in either of your homes for Mom to get a hold of.

Your mother is very dangerous. She could have seriously hurt you.
See if your state has the Baker Act. She needs psychiatric care.

From your profile:

"My 89 year old mother is my next door neighbor and is suffering from paranoia, narcissism and a form of dementia. She is such a mean, bitter, miserable woman that she is totally isolated from everyone. Last night she came to my door to accuse my husband of stealing 2 tools from her house. We NEVER go into her house but she’s always accusing us of stealing and ransacking her place. She lifted up her hand above her head to hit me with the tools that she said my husband replaced hers with. I was able to physically protect myself. She is the reason I searched for this website. I need clarity and advice and support without condemnation."

You need to call 911 if she even just threatens you. Tell EMTs she's volatile, has attacked you in the past with weapons and may have a UTI. At the hospital she will be tested. This is your opportunity to transition her into a facility. She is an unsafe discharge. Ask to speak to a social worker on how to have her go into a facility directly from the hospital.

If she currently isn't taking any meds for her agitation and aggression, then this will need to happen while in the hospital before she can go into any facility.

My 95-yr old Mom lives next to me. When she gets paranoid there's no convincing her since dementia robs people of their reason and logic and empathy. She came to me yesterday insisting I had 3 of her spoons. I knew I didn't but I looked anyway. Today she came back to the house when she knew I was gone but my husband was home and looked through the drawers again, and of course didn't find them but she hasn't asked me since. I don't bother trying to convince her of anything -- it never changes or eases her mind.

Your Mom needs facility care for her sake and yours. Please take care of yourself! I'm so sorry for the loss of your son (and for all the years of distress that I'm sure preceded it). May you receive peace in your heart.

Have some little companion cards printed up to hand out to strangers when mom starts acting up:

There's a ton of them online if you Google "dementia cards".

Call 911 when mom threatens you, as mentioned. This is NOT about compassion but your safety at this point. Violent behavior is common with dementia, unfortunately.

Good luck to you.

There's no reasoning with the asinine nonsense dementia brings to the party. So don't even try. Your mother is clearly out-of-it with dementia and belongs in a memory care facility because she is a danger to herself and others.

Don't wait until she seriously injures someone or burns the house down before you call APS and the police on her.

She belongs in memory care. Put her in one or let the state put her in one.

Not sure if you can do anything to convince in this situation. Unless he is cognitively sharp enough to look at her bank statements . But from what you describe, sounds like she is probably not sharp enough ?
So then convincing her may not be possible. But what if you just say "no they arent" then just change the subject. Or ignore if she persists. Anyway, even if she thinks they are stealing, what is she going to do about it? Probably she cant do a thing. if she tries to tell others that they are stealing, just shake your head so they can see that its nonsense.
This stuff is not easy to deal with, I agree.

Please take the threats & safety concerns seriously.

This is what I will add if you want names & info about this behaviour:

*Paranoia*
Unfortunatly, this problem of 'stealing' is reported as a very common symptom of dementia.

*Confabulation*
An item can't be found. The brain likes to solve problems - so reasons items not found MUST be stolen. By theives, neighbours or family they see regularly. (Sometimes by ghosts, faeries or pixies too).

*Fiblets*
You may need to consider some fiblets to where that item got to.. borrowed, broken, moved etc.

As you drive your Mother, could you drive her to a Doctor appointment? Talk, visit or write to the Doctor beforehand to advice the behaviour concerns. Have Mom go for a 'checkup'. The Doctor can do the checkup & (hopefully) a quick cognitive screening test. It's not a cure & she may refuse, but it may be worth trying.

My mother did this too. Just to offer a different perspective from my own experience...

I used to spend hours finding “stolen” items, thinking I’d ease some of her anxiety. “Oh, here it is. Gee Mom, you misplace things almost as often as I do.” (Laugh it off.)

One day her purse was “stolen” 7 times (she had enlisted my husband and kids to hunt, unknown to me, until we all discussed our day later) and, as I went to help her, she muttered “You’ll never find it this time.” What?!?! I did, and she was angry. From then on I just shrugged and said “Sorry to hear it. Guess you’ll have to make do without.”

Seemed a mix of paranoia and an attention seeking game.

Your moms brain is broke. There's not much more to be said than what others have said.

Have you learned about dementia. If not please YouTube Teepa Snow. When you understand it more, you have more compassion and understanding of what's going on with the demented.

Best of luck

OK because it is me responding...I am a firm believer that a person with dementia should not be living alone.
Do you have POA for mom? If not you may have to get Guardianship as it sounds like it would be impossible to get POA documents signed.
Mom should either have caregivers or mom should be in Memory Care.
You would have to help her less if she were in Memory Care.

If mom owns the house selling it would provide assets that would pay for MC.
Even with the cost of MC with no property tax, no insurance as well as all other household expenses that she is currently paying the asset from the house sale and any other income she may have would last a while.

Another option..she remains at home with caregivers.
To cut back on the caregiver expense if she could get into an Adult Day Program 2 or 3 days a week that would keep her occupied and no need for caregivers when she is at Day Care.

How often do you drive her around? Caregivers can take her to the store.
If it is to doctor visits, how often are they? and can they be cut back on?

Oh to answer your question...no there is noting that you can do or say to convince your mother that no one is stealing anything from her.
With dementia what she believes is what she believes.
What she says is true, is true.
If she is convinced that a group of people came in and took her toothbrush then a group of people cam in and took her toothbrush, just get another one for her.
