Should possible sudden delirium(?) change our plans?

Hi.  Does anyone have experience with delirium or psychosis that came and went after a major life disruption?  

We are feeling desperate right now! 

It is regarding my husband’s parents (Sally 84, Fino 93).  

Background:  

They have refused to move to an AL over the years, and with some outside assistance, have managed to stay in their home in MD of 65 years. We live in SC and their other son is in FL.

Sally has had mild dementia for several years.  She is very healthy and has no physical limitations. She cares for herself (bathing, toilet, putting on makeup, doing her hair, dresses herself nicely, etc.)  She does need someone to give her her daily meds, and is confused about foods/meals, though she can make eggs, get things out of the fridge, heat things in the microwave, and puts them on a plate and eats at the table.  She cleans up the kitchen, and does laundry.  She is never violent, angry, or verbally abusive, and has never wandered outside.  

Fino has been caring for her, but has bladder cancer which has now advanced to closing off his one kidney and eventually will close off the other.  He does not want any treatment, and is getting frail; it’s only a matter of time till he passes from kidney failure.  Since he can no longer care for Sally in his condition, he asked to be moved to an AL facility (by himself).  We  moved him last week and he is settling in.  It is about 15 minutes from their home.  Sally showed no emotion about his move and, in fact, never showed any emotion about him having cancer.  

We stayed with Sally in her house after Fino moved and took her to visit him 1-2 times a day.  She seemed to do okay with his move EXCEPT that some of the furniture and one TV were missing (they went with Fino), and we had some of our belongings (luggage, food) in the house.  She expressed a lot of anxiety about that.

Side note:  Our plan has been to bring Sally down to live with us in SC in an apartment over our garage, with access to our home. (There is no oven, stove, or microwave there.)  We live in a beautiful, safe place, we are retired and have time to care for her, and we have cats which she loves.  This arrangement would be until she requires more care, at which time we will move her to an MC facility.

However, 4 days after Fino moved out, Sally started experiencing serious agitation and anxiety.  She started having delusions and hallucinations (seeing her mother, babies, other people), forgetting who we are.  She’s had occasional delusions for years about someone stealing her clothes, as well as poor short-term memory, but THIS was like an emotional storm suddenly hit her.  She could not sleep, wandered around the house clearly upset, confused about where she is, etc.  She constantly demanded to see her (long deceased) mother and was very upset that she couldn’t.  She asked non-stop questions about who is who, when she was going home, etc. She was not doing any of this before Fino moved out.   

We suspect psychosis or delirium triggered by Fino’s move, but not sure of that as we are just learning about this subject.

Her doctor actually visited her at home, and we had her checked for a UTI (negative).  Her neurologist seems disinterested and simply prescribed an antipsychotic, which has helped her to sleep at night. 

That is all by way of background (sorry it’s so long).  What we are wondering is…

She cannot live by herself, and we cannot live in MD with her indefinitely, so we have to move her SOMEWHERE.  We are still thinking to bring her to SC to live with us, with the hope that this sudden change will end and she will return to her prior “normal” and perhaps settle into a routine in a new environment which is much more pleasant and engaging than where she has lived.  Is this a possibility? Or should we assume she just needs to go into MC now?  We hate the idea of putting her in MC because she was not ready for that 10 days ago!  But we cannot handle her in the highly-agitated state she is in.

Wow, if you read this far, I truly thank you!
