My husband believes that there was 3 of me. One that left. He called my son and told him that it was time for the other lady to leave. He has an appointment with the neurologist December 4th. Doesn't remember me doing things with him and is confused as to if it's me or this other person. I took care of my mother in law and sister in law both had dementia. This is so hard with him.
Call his primary care doctor now if you haven't already.
I don't think it is his medication. I brought him to the ER and they checked his blood. Everything was normal. I started noticing changes in him in July. Just moved from Texas to New Hampshire and getting doctor appointments here is awful. Seems like you have to wait forever when he could be getting some kind of help now.
Call his PCP to discuss the situation; don't wait until 12/4 to get a urine specimen in for culture!!!
Good luck!
