DH becoming more negative and angry

I'm so sorry you're going through this. I'm right there with you, though my DW is a little less angry at the rest of the world, but has decided that I'm the problem. I'm controlling where she sits, apparently, and controlling her life and making all the decisions. I'm not doing any of those things yet, because I still ask her what she'd like to do even if she can't really figure it out on her own. It's so much fun to be in charge of everything, giving everything all your love and attention to be told how much you suck at it. Sarcasm is my only savior right now. I still haven't developed thick enough skin to not be hurt by the person who used to love me so much, really resenting me now.

All my own complaining aside, I do think the idea of an anti-depressant is worth trying out for your DH. That has helped my DW, but I think the new addition of hallucinations has probably pushed her to needing something else here soon.

Exactly where you are. You can't keep him happy. Don't try. You can't reason with him because as other said to me, "his reasoner is broken". It's caused by their loss of control and happens when he's stressed. Not your fault. My DH talks constantly when we're in the car. He complains about the bumps in the road, the other cars, how I apply the brakes, did I check the tires? It's called chattering. I try to ignore it but it makes me so nervous I don't enjoy going anywhere with him anymore. Yes, medication will help. My DH is on Risperidone for agitation & hallucinations but it hasn't helped his chattering in the car. Get a referral to a Geriatric Psychiatrist if you can. They are the best ones to monitor medications. Ours has been the only doctor who has helped. We tried Mirtazapine for depression but he reacted badly so he's off of it. Waiting to see what the doctor wants to try next. Write down his behaviors so you can communicate them to the doctors. That helps me more than anything. You get so little time with the doctor and it's difficult to remember what you want to tell them.

My husband is on seroquel and Zoloft. Seroquel has helped anger issues significantly. Zoloft was recently added to address OCD tendencies, jury is still out on that.

there are still some eggshells situations, but much less and shorter duration. I would pursue. His neurologist prescribes.

Lexapro (?) - escitalopram - has been the right antidepressant for my partner. Has helped with mood and the constant criticism of every breath I take.

We are living the same life with the same man. I have almost bitten my tongue OFF trying not to say the wrong comment that sets him off. The constant barks at other drivers. I agree, Zoloft is on my to do list to discuss with his Dr. I am surviving by watching Teepa Snow videos. Alzheimer’s horse whisperer. And Joyce Myers. I go on walks to have private conversations just to have normal conversations. Praying for you!!!!! I know EXACTLY what your going thru.❤️❤️❤️

You'll find a lot of threads on these boards debating the necessity of a neurologist once the diagnosis is made. Some want one, others do not. the brutal truth is that they don't have much to offer therapeutically, and if they are unfeeling on top of that, I'd let it go and see if there is someone better out there that can meet your DH' needs.
