My husband is angry at me and will not eat or sleep in the same bed. He has early Alzheimer’s and he seems to hate me. Any advice?

Lots of great answers here on dealing with Dementia, UTI. As someone else said on another post is to try gentleness in dealing with his grouchiness. Have you tried a serious talk— Dear, I am on your side. This is our marriage. We are a team. You do this and I do that. If he’s being abusive that’s another whole issue and you need to be in a safe place.

Ellie, do you not drive? I realise this isn't the main point of your post, but it will become an issue. If you don't, perhaps you had better learn. Or get used to Uber.

If your husband doesn't respond to your questions about what is upsetting him, how about just stating the facts. Say something like "I can see you are upset and angry. I would love to help put things right."

It could be simply a phase of the dementia on its own; but if it were I'm not sure you'd have got the chauffeuring complaint. Bear in mind that he can be angry in general, and upset in general, without its being anything you have done or, sadly, can help.

You probably didn't do anything. He has dementia. His brain is broken. If this started a few days ago, I suggest you report it to his doctor. Also inquire whether a test for a UTI might be helpful. (UTI has strange behavioral symptoms in older people.)

This anger may pass as suddenly as it came on. Or not. Sigh.

Early onset ALZ is when the dementia starts before age 65. Is that what you meant? Or did you mean early stage dementia -- near the beginning?

Have you reported this change in mental status to the doctor who is following his dementia?

He may have a UTI.  He may be going through a paranoid stage.  There are meds that can be prescrbed for his agitated behavior.
