Does anyone's LO talk endlessly?

It's not normal. It might be organic (tumor? [I'm no doctor]). Needs testing. Or some kind of psychological syndrome.
Mostly, save your own sanity. It's abusive and traumatizing. Maybe he can't help it. How was he before this started?

Hello:
My husband doesn't seem to be as extreme as yours, however he does talk or narrate all day. He says the things outloud that most of us have going on in our inner dialog.
He'll say outloud what is happening on TV, narrating the scenes, and any activity or action he is giving me a play by play (I'm getting my hat and coat, I'm going to the bathroom, I'm putting my cup over here); EVERYTHING is said out loud, all day long!
I purchased noise-canceling headphones for my own sanity. If he's asking me a question I remove the headphones temporarily.
All the best to you. 🫂

I have the same problem, but WE don't talk, he just does! When I start to say something, virtually every time his first comment is, "stop! I have to pause the TV/stop reading/stop looking for my glasses/find the remote/finish buttering my toast!" And he makes such a big deal out of it that by the time he says, "okay, now what do you want to say?" it just seems too much effort or not important enough.

And he makes such a big deal out of it that by the time he says, "okay, now what do you want to say?" it just seems too much effort or not important enough. He has just been diagnosed with Alzheimer's and is in the very early stages, but this has been a pattern for a long time, and when I start to say something, he will start to say something in the middle of my dents as if he is not even aware I'm talking (his hearing had been tested and is perfectly fine.) Even though I know part of this is the disease, it is just so demoralizing to not be able to have a normal conversation.

So sorry. My mom went through a phase of talking without me being able to say anything but it didn't last long. Sometimes medications can help.

I hope this passes for you and your spouse.

My husband has been diagnosed with early Alzheimer's. He was always pretty quiet at home and just went about his business reading the paper or checking emails etc. Now he reads the paper to me, follows me around and starts talking to me the minute I walk into the room. If I am elsewhere in the house for too long he comes to find me or starts calling for me.

He asks me the same questions ever day all day long. Usually about the days appointments or activities, our finances or asks me to explain where we are (at home) and then insists we actually live in another house. At night he is confused about where he is going to sleep, where the kids are (they are long grown and gone) where the other dog is (we only have one), where the cars are or whose cars are in the driveway, and it goes on and on every day. This seems more advanced to me than early stages. I am very patient but it is absolutely exhausting.

My LO does talk but not as bad yet. He has always been a talker and will talk over others and interrupt, but gets upset if others interrupt him. He definitely believes his utterances are more critical than others. He tells his story in a lecture style and can go on for a very long time. He does tell me what he is doing, and I find that helpful, as he still leaves home for short periods and fiddles around the yard. He has been lost in the backyard once already. I need to know where he is, as he will probably really get lost one day. He goes to a local memory day respite for 5 hours once a week and goes to bed about 3 hours before I do. All gives me a break. I also have a volunteer visitor once a week, with whom I can discuss a wide range of topics. She has been coming here for about 2.5 years.

My husband used to be a DJ, and had a television show locally in the Bay Area. He will announce songs on the radio, do ‘voiceovers’ of commercials., etc. it’s quite entertaining. That is unless it’s 11:30 and I really want to go to sleep. I’ll laugh at him and let him know he’s been talking nonstop for about 2 hours now. He’ll laugh and stop, for about 5 minutes.

Then there are the nights he goes on and on about a recurring theme for him… he gets it in his head that I want to leave him. It goes on for hours and it doesn’t matter what I say or do, and only sleep stops it. I get up, go fix some tea and stay up until he falls asleep, then I’ll get in bed. I feel this is a mild version of what may be to come.

I’m told it may be sundowner syndrome, and medication may help. We’re not there yet, but I will be exploring it.

This discussion is blowing my mind! I think we’re all married to the same man! My husband talks endlessly, tells the same stories over and over and over. If we’re with some other people he will hijack the conversation, so embarrassing when they don’t ‘know’ why. When I’m attempting to converse with him, I can tell he isn’t listening, has what he wants to say next stuck in his mind, interrupts, and when I call him out says that I stopped talking—I paused for a split second or it was just the cadence of what I was telling him!!
He also narrates the tv, guesses what will happen next or asks me what’s going to happen, I haven’t seen it before…. He turns off the sound instead of pausing the tv to talk. He used to be in charge of large construction projects, so we have to pause the tv, or even back it up during shows so he can show me one that I already know he worked on, or he ate dinner in a restaurant on tv or he walked on a sidewalk, ugh! Sometimes I suggest that we watch something else because we have paused so many times I can’t stay invested in the storyline.
He also announces what he’s going to do every minute and says things out loud that the rest of us think to ourselves, like yours @judimahoney.
He used to badger me about my therapy until I cried @blc1951 before I even had a clue that he might have dementia. One time I took my sadness and distress over his cruelty to a whole crazy level and played it out for hours to send a message, he even called my therapist, himself, at the time. He still keeps a balance of how much I’ve spent
on therapy and throws it out there occasionally. I should have started noticing clues way before. That cruelty was/is so out of character for him.
He plays guitar, and he has started playing guitar while watching tv in the family room/kitchen area, where I am working doing cleaning or cooking or 1000 other things. I am a prisoner where I am working, but there are other
places he could play and/or watch tv. Because I can’t stand the multi sounds at the same time I put earbuds in to listen to music and take them out when he speaks. Being considerate has been completely wiped out.
@sandyar He reads books and tells me what he’s just read all of the time and it’s long drawn out repetition of what he’s read.
And don’t you find yourselves, like you @theglobalnomad1, think of something to say, but then think carefully if you even want to open that for discussion, because of where that discussion could go or you are just too tired and exhausted.
I do complain a lot, but I miss him so much. We met at 15 (from different states) got back together, then married at 19, and have been married 52 years. I would have loved having him to myself again and to have fun going places and doing fun things and enjoying each other’s company. It is what it is.
Thanks for reading this far…
And my whining…

@lkbous I sometimes feel guilty and ashamed at complaining because I do know it is not him... but it is exhausting, and overwhelming and leads to a sense of loneliness. Hard to know what to do because nothing with stop it.
