Are these early signs of dementia?
I am in my 40s and my mother with me who is her late 60s, residing together. My mother has always been up/down but never like this and I see things getting worse over the years. One day she is okay, another day she isn’t. You never know what mood she will be in. She can be very argumentative and verbally abusive. Today a simple comment and she turned around and said stfu ... how I am a terrible daughter. In public she is one way unless someone really upsets her. Behind closed doors, she gets upset over things I say, expressions or misinterpret things lately. Something so minor can set her off and then she will twist what was said or done and say its me and request an apology.
Lately she has been increasing with swearing, verbally attacking and mocking me or bossing me around. I really think there is something wrong and she will start arguments to cancel doctors appointments and say I am purposely doing it and responsible for it. When she does finally shows up, she will not listen to the doctors if she doesn’t agree with them and does whatever she wants. I have a full time job and take time away from it for her to not even listen or follow the guidance. She will find a reason either the staff or the doctor being an issue. If I try to say something she will get upset, lock herself in the room and then turn around and plays the victim that no one is checking on her. I found writing on the walls. She sends texts that are lies and not what has occurred and says I am going to be in trouble because she is a senior and I am responsible if something happens to her for not checking on her. I ignore all the rage texts. I stay to myself to avoid conflict. I noticed her leaving kitchen cabinet doors open but she says she does that purposely. She can’t sit still and will stand there while I am busy and continue nitpicking or telling me what to do, which starts an argument. I suggested separate residences and she said I was kicking her out when that wasn’t the case. She thinks everyone is up to something or plotting something. I can’t even have a life because she causes so much conflict when I attempt to. I am isolated. If I try to speak to someone on the phone she will start an argument or purposely say something to cause embarrassment. I am truly alone and don’t know what to do. I am frustrated emotionally and mentally but her reality isn’t what is occurring and she will continue to defend and argue it no matter what to make me look one way and say she is a victim here.
Are these early signs of dementia or something else?

You need to move out as soon as possible. Do not waste the next bweast years of her life with her manipulation! You won't get that time back, either.

Your 40's and 50's are the best years of your life! Don't waste them with your Mother' abusive behaviors. It could be dementia related, which will only get worse. These are not "early" signs, either.

You need to start looking for a place, if you live in her home. if she lives in yours, that will not be an easy process. Your reason to separate is because of the stress and DRAMA. Good luck in getting this one handled!

Thank you for replying. I feel like I have wasted so much of my life already. Because of the dynamic I can't have friends or date given all the drama. When it heads that direction, she will stir up some sort of argument so I isolate myself and stopped speaking on the phone because of her outbursts and what she may say about the person to hear. All I hear is her saying what about me and everything I have given up as a parent, who is going to take care of me. As I sit there thinking I have spent all this time and I won't have anyone and may end up alone, but she isn't even thinking about that. If she is being this way now, can you imagine how she would react with something bigger. Some nights I cry myself to sleep and wouldn't wish this on anyone.

The behavior you describe here sounds like a woman who knows full well what she is doing. She is cleverly manipulative. Someone with dementia will not be able to create such manipulation. She may have a mental/emotional disorder.
If she were willing to see a doctor and cooperate with their advice, she could possibly get a diagnosis and treatment.

It is possible that she is beginning to have some cognitive decline, but she would have to be seen and tested by a neurologist to confirm, and it sounds like she will not cooperate to see a doctor for a diagnosis.

YOU can not control any of this. You can only control how you respond to it.
First, I would start by stepping back from trying to meet her needs and take her to appointments, which is just a time waste for you and gives her attention for acting badly.

I think it is a big mistake for you two to be living together. Her behavior will not change or settle down, it will only continue and probably get worse, until you just can't take it any more. If you share a deed to the house, you need to figure out a way to undo that and go your separate ways. Give her whatever money she is owed for her contributions to the home, and remove her name from the deed and kick her out, while you continue living there, or sell the house and use the proceeds to live elsewhere, much like when a couple divorces.
Late 60's is not old. She can manage her own adult life without you. And, hopefully you can manage your adult life without her. This is a toxic co-dependent relationship which does you no good, and it is time to change it.

I thought the same thing which is why I am questioning if its more mental health related. She will not go to any appointments and if anyone suggests testing, she will flip out. I have made many different living recommendations, and she turns around and will say she has no options despite giving her everything and she wouldn't have to worry. It's like I am dealing with someone who plays the victim but doesn't give the full story of what's occurring and will say it's me.

You can call 911 when she is acting up. Tell the dispatch that she is making threats to harm you and herself. They will take her to the ER for an evaluation. Save all the threatening texts she sends you, and when she starts going off on you record her with your phone. Or put up cameras in your home. If it's your place, you have a right to do this.

The cause of her abusive behavior could be mental illness, dementia, or both. When I hear a story about a parent who gaslights, then presents their false version of events to others as a way to make their adult child look bad, and plays the victim, there's usually a long dysfunctional history of this behavior in some form or other. It's abusive. Whether it's dementia-related, mental illness, or addiction related really doesn't matter. Abuse is abuse and no one has to live with it.

If the home is in fact yours, you may have to serve your mother with legal eviction. If it's a rental, it may be a good idea for you to start looking at apartments for yourself and to move without her.

You cannot force her to go to the doctor. You can privately communicate with her doctor and APS. Tell them about these abusive behaviors and spare no detail. If you can manage to get some recordings of her, play these. Her doctor and APS should be made well aware that the two of you will not be living together anymore and you will not be her caregiver under any circumstances. She will be left entirely on her own. They will act. If APS does not, that is on them not you.

You are not legally responsible for your mother because of her age. She obviously needs care and supervised living. You are not the person to provide this.

You said she has always been up and down? Maybe Mom has a mental disorder like BiPolar. One they are fine the next day they are manic. I believe that people that suffer from mental disorders also get Dementia when they get older. Mom needs a good check up. Medicare will pay for one physical a year.

She has insurance however is either a No Show for appointments or does not listen to the guidance she receives. If they push, she uses a different doctors and makes an excuse to never return.

I agree with others that you need to convince her to go in for an annual physical. She's not yet 65, so not on Medicare. Does she have health insurance? Does she have a regular primary doctor at all? Do not take her to the ER because they don't diagnose dementia there. Dementia is mostly diagnosed by discounting all other possibilities. Some dementias can be seen in brain imaging. You can take her to Urgent Care to be checked for a UTI, which becomes very common in older women and often have no other symptoms except for cognitive and behavioral changes. Other things that can cause personality changes are TIAs (small strokes), brain tumor, etc. This is why she needs a thorough exam.

In the bigger picture, you Mom may need someone to advocate for her if she becomes less able to do it herself. I would strongly suggest going together to a certified elder law attorney where s/he will explain the importance of assigning a PoA.

That's the issue she is over 65 but refuses to go to appointments or disregards the doctor's feedback when she does show up. If you attempt to suggest something an argument starts after the appointment or she selects a new doctor and repeats the cycle over

Send a message through the patient portal describing the behaviors you’re seeing to mom’s doctor. Schedule an appointment for her and make up a lie if needed to get her there. Make sure she’s tested for a UTI and your concerns are addressed. No matter if this is dementia or mental illness or just meanness, it’s likely wise to live separately. You deserve a peaceful home and not to be verbally berated. Meanwhile, don’t react, argue, or give her an audience. This has to be miserable, I hope you can find some answers and a new path forward soon

thank you, I feel isolated and don't know what to do. She refuses to go to appointments or disregards the doctor's feedback when she does show up. If you attempt to suggest something an argument starts after the appointment or she selects a new doctor and repeats the cycle over. I don't speak to anyone because if she hears it turns into an argument. If I attempt to go she wants to go that starts another argument. So I just isolate myself to not bring drama to others

SupportGroup, welcome to the forum. Have your Mom checked for an urinary tract infection (UTI), as such an infection can mimic dementia. Urgent Care facilities usually can do the test and have the results while you wait.

Thats the issue she won't listen or go to appointments. If I attempt to speak up and suggest something at the appointment when she does eventually go, an argument will occur afterwards.

If M is only late 60s, whether or not it's dementia, this is probably going to get worse. Much worse. You need to live separately. She thinks you are kicking her out, and in fact that is a really good idea. Don’t wait until your relationship is totally destroyed before you separate.

Thank you unfortunately, she sees everything as the opposite and uses it to start an argument. The average person can see this is the best solution to avoid things from escalating but she doesn't
