Dementia patient all of sudden starts being angry at one person?

Keep your self safe! Brain conditions are so unpredictable! Hugs and prayers you way!

Your.

I had to hide my husbands key's because he cannot drive. Oh, was he so ANGRY! He thinks in his mind he will drive again. Nope will never happen. He doesn't focus and cannot remember where places are. I am just trying to keep him safe. When his Dr.said he should not drive, he took it as a YES! No way will he ever drive again.The anger towards me is above and beyond. He thinks that I want to ruin his life. Actually I think he has made my life unbearable at times. He is falling more and more. The last one was pretty bad! Just another day and what will come next.

Our basement was stuffed full of things saved “we might need”, I piled a lot of medium to small stuff against the locked door to the gun closet. ALOT of things, I knew he would get distracted and tired trying to get through it. He never got through it, I think he forgot about them too.
I felt somewhat unsafe from his intermittent tirades and wandering around, especially at night. I told him I was going to sleep in one of the kids bedrooms because he was waking me up with the up and down. He didn’t like it, but didn’t argue. I slept the best sleep in months behind that locked bedroom door.

Maybe get rid of the gun?
I've asked my husband to sleep upstairs because he was disturbing my sleep so much. I do so much better when I have a good night's sleep--by myself. He didn't want to go upstairs, but he's doing it and I have some relief.

I don’t know where the key to the deadbolt is and he refuses to tell me. I think he has some insight that I would get rid of them. I’ve suggested giving them to our son now (40’s), but he says our son will have to wait until he dies.
The irony is that 30 years ago, we moved from Boston to a PA rural county for an excellent job opportunity. The local guys he worked with until retirement were (of course) into hunting, fishing and guns- muzzle loaders, black powder guns, long rifles, etc, etc. Guy group meet-ups at the Grandpa’s hunting camp during this and that season, Guy meet-ups at the nearby State Gamelands Shooting Range, membership in the local private Shooting and Archery Club ranges.
It’s a whole different world neither of us had any idea of and he took to it like a fish takes to water. He was very happy and I tried to be happy for him, he was very very careful about safety, but it was not something I was ever happy with. A friend said to me once, “Why do you let him have those guns?”. My immediate thought was, How nice for you that you have a husband that you can “let” do things, mine would laugh at that idea.

I understand completely. Perhaps you could get a locksmith to undo the deadbolt. Is your husband ever out of the house? You could have this done when he's out of the way. You should be making the decisions now, not your husband. It's so hard when the person you're dealing with today isn't the person you knew before. The rules of the game have changed and now you're the captain.

Years ago I visited my mother, who was living alone in Florida, and was alarmed that she slept with her gun under her bed. She hallucinated that people were stealing from her, and had called the police about imagined thefts. I was fearful about that gun, and when she napped I turned it over to the police. When I got back from the police station she was waiting for me at the door and demanded to know where her gun was. She kept at me all day and night - I pretended to be asleep in my bedroom but was quaking because I had recently read about a woman with Alzheimer's killing her daughter when the daughter threatened to put Mom in a nursing home. My mother ended up leaving the house in her car, being picked up by the police, and being Baker Acted (evaluated for mental stability). She was medicated and soon was admitted to a nursing home.

With dementia, anything can happen. When my husband is angry with someone. I ask him why. Sometimes it makes sense, other times, it doesn't.
If the person hasn't harmed him, which is usual, I let it go. After a while, he forgets and can start anew with that person.
If it's someone the person with dementia has been used to seeing for a while, you could try having that person stay a way for a week. Odds are the person with dementia will forget.

Thank you
