She acts like a child. She blames me for her misplacing things, she says things that don't make sense and contradicts herself all the time. Says I'm picking on her. She lies about the silliest things. I'm lost as what to do or how to deal with this. I get impatient and frustrated with her..I feel like a bad daughter
When she lies about things, just keep reminding yourself it is the dementia *talking*... don't try to correct her, it won't help.... try to find some humor in what she says, she is probably saying the darnest things.... agree with her and giggle to yourself.
I'm the first one mom accuses of stealing things, or gas lighting her, or ignoring her, etc. she has even reported my brother and I having stolen this or that or burglarizing the house...we're professionals and live out of state. It's frustratin and sad....and sometimes I have to just take a break or take a time out to deal with it.
What I can tell you is that you can't reason with her or snap her out of these accusations or paranoia, just go with it and stay calm. Don't deal with her, if you can, when you are tired or stresses. Not all have that luxury...I do because I don't live with mom and I'm not a full time caregiver.
My mom lies to. I deal with it over the small stuff, but sometimes when she keeps it up and I know she is in her right mind, I call her on it. I don't get angry, I just calmy say " mom, when you say such and such, it hurts me when you know that's not true.." Or I have stated, "mom, I don't want to listen to this, let's agree to disagree". If she keeps it up (and she doesn't so much lately), I just tell her I'm leaving and will see her in the morning, or I tell her I love her and hang up the phone and ignore her calls for a few days while I cool off and she gets the point.
It's sad...but it doesn't get better...you just have to steel yourself and learn to cope with it. It ain't easy....
I posted an answer to a similar question several days ago. I'm going to repeat part of it here, because a few people told me it was very helpful to them.
Why is your mother behaving this way? Because she has dementia.
You will be doing yourself and your mother both a favor if you accept that a person who is losing her ability to reason cannot be consistently rational. Expecting rational behavior and accurate answers is just asking for high-level frustration.
(I know. I've been there, done that, and have the scars to prove it.)
Why ask her for explanations? An answer won't change anything. As an example, how about "Oh dear! The faucet got left on. We'll need to clean this up fast. Can you help me? I'll get some rags and a bucket." If she explains that the dogs did it, say, "That's OK. I am sure it was an accident."
Don't ask if she knows where anything is. Of course she doesn't. She has dementia, remember? You might try, "I am so sad. My red-handled scissors is missing and I need it now. Will you help me look for it?" That gives her a chance to be a hero if she has a vague memory of where it might be, and no reason to get defensive about it. Remember the goal. You want the scissors, not to establish guilt.
Acting childish is extremely common in dementia. She is NOT doing it to get attention or to annoy you. She is doing it because there is a physical defect in her brain which is preventing access to more mature behavior.
She may never again be able to do even familiar chores that involve organizing things or multiple steps or complex decisions. Just can't do it. Try to find tasks that give her something to accomplish that she can succeed at. Matching socks from the laundry, folding towels, possibly polishing silverware are examples.
Adjusting to living with someone who has dementia is very, very hard. It will always be hard, but it can be a little easier if you accept that your mother's behavior is limited by physical flaws in her brain (plaques or tangles or protein deposits, etc.) She can't help her behavior. To be successful with her you'll have to adjust yours.
There should be no shame if you can't make the necessary adjustments. It certainly does not make you a bad daughter. I think you have a duty to see to it that Mother gets good care, but not necessarily to provide it yourself.
Fast forward to today, and Mom is completely sedentary, can barely walk more than 20-50' at a time (50' is a stretch and she usually has to sit down halfway), is becoming incontinent (urine only, so far), refuses to shower until I get stern with her about it and only THEN will she shower, forgets to wipe herself in the bathroom or flush the toilet, forgets to take her pills, doesn't want to go anywhere during the winter months at all - not even to our Sunday breakfasts unless I push her to get out and get some fresh air, and is perfectly content to vegetate in front of the TV. All that happened over the course of 15 years, but it has really accelerated in the past 2 years. It's like since I moved in to take care of her, she has just given up.
What your mom is doing is normal, unfortunately. It's part of the process. None of us are perfect, and caregiving is NOT for the faint of heart. No one is born knowing that one day they will have to wipe their parents' backsides, clean up their accidents, make them shower, etc - it's a task that is usually thrust upon us all of a sudden, and we're left to figure out how to adjust our own lives to handle it. Some people just can't do it, and there's nothing wrong with admitting that. You shouldn't feel guilty about saying, "I just can't do this" - because not everyone is cut out to be a caregiver. Given the choice to have someone else do it - and do it well - I'm sure many of us would be out the door, coming to visit, but not doing the full-time caregiver thing. I fully admit that I would like to have my life back - but I know that no one else in my family will (or can) take care of Mom, so I stay.
And just to rant a little on some things people can say...like "what a blessing" really? Just who is it a blessing for, my mother who can't remember her name or where she is or my name or that my father passed away 14 years ago, can't control her body and is deteriorating a little each day? Me, who has no life and can't even go visit my children, has a bed in the living room with no privacy and can barely make it through each day? No it is not a blessing, it is a burden. She can't go in a nursing home, don't even ask why or about other family members helping, it's just not doable. and the people who say "it won't last forever", it FEELS like forever and, honestly, I don't know if I will make it, physically, mentally or emotionally. Three meals a day (I have to rush home at lunch hour and fix her lunch and clean her up and hope I get back to work on time) snacks (she can eat and seems to always be hungry because she forgets she just ate), cleaning a potty chair, her, dressing her and seeing to all her needs, working full time and just having no life for myself just plain sucks. Is that selfish, who knows, but whether it is or not it doesn't change how I feel about it all. I love my mother and do my best but for her, but the mother she was is gone and I am just the caregiver for the body that is left. And please never say to a full time caregiver for an elderly parent, "they took care of you when you were a baby and a child and did the same things", there is a WORLD of difference between caring for a 6 to 10 pound baby and a child who can learn when you are in your twenties and thirties, and caring for a grown adult that weighs 150 pounds when you are in your sixties. So don't even think you know unless you are doing it full time. No matter how tough you think it is when they are in a nursing home or someone else in your family is taking care of them and you just visit or listen to them complain, I would trade the circumstances in a heartbeat. It HARD and how you feel is how you feel and if someone doesn't get it, it does not change that feeling. So just try your best and accept we are not perfect, all the answers don't fit us, well meaning advice is just well meaning and may not be the answer for you, and it's ok to hate what you are doing without hating the person and for God's sake make sure your children do not have to do what you have to do for your parent.
