He is convinced he divorced me and married his "doctor" while in a rehab facility after shoulder surgery. He tells the physical therapists that I am the ex-wife and he will be going "home" in a few days.
At least once a week he says she will be here to get him. Then he changes the date or makes excuses why she is a no-show.
Other delusions - he thinks we are wealthy, he is a doctor, pilot, attorney, architect, etc.
He is in total denial that he has Alzheimer's.
However he always thanks me for the meals and tells me how great I look. His long-term memory is amazing, but his-short term memory is terrible.
I'm not looking forward to our anniversary in May.
With being a caregiver you realize that "holidays" are just another day on the calendar. You still have to follow the same routine. And lots of company or noise can disrupt the person with dementia. They don't get it. So keep "holidays" low key. For your anniversary make something special for yourself and try not to stress if and when he does not realize what the day means to you.
As to the delusions. As long as they are not harming him or you and as long as they are not frightening him ignore what you can and if you need to "play along". You can't argue with a person that has dementia so don't even bother.
If the delusions are increasing mention it to the doctor. If they begin to frighten him mention it to the doctor. If he begins to become violent you MUST protect yourself. Call 911, tell the dispatcher that you are afraid for your safety and ask that he be transported. If you feel that it is unsafe you must tell them at the hospital that it is unsafe for you at home if he were to be released to home. This also applies if he begins to threaten self harm, or do things that are dangerous.
Make sure that there is nothing that can be used to harm you or himself. Knives, guns that can be used should be locked up.
