My dad was fine before surgery and now they are drugging him and wont let him out. What can I do?

Tried to get daddy out of Geriatric Psych Rehab today and he was too drugged to come home. He has declined since he has been there - at least that is what I see. The facility is telling me that he is getting aggressive (normal for facility, never at home). I went there today to bring daddy home and allegedly he acted out yesterday and they had to sedate him to calm him down and allow him to sleep.

I did not bring him home with me as I was too scared. They scared me, also his release would have been AMA - I had no clue as to what I would do if he acted out here with me - even though I doubted he would. But he was so drugged, I was even to scared to drive him the 1.5 hour drive home.

I have no idea what to do. His history in facility is bad (agressive, confused, etc). He was perfect at home with care - still caring for the dogs, mowing the lawn, paying bills, etc.

Can a person get so bad after 2 months that they are not even the same person? I may be in total denial here, but my dad is physically okay - his dementia is obviously progressing, but to what extent? And cane I care for him at home, or can I have him cared for at home as I cannot move here until Summer???

And if his dementia is progressing, aren't the sedative/anti-psych drugs (seroquil - I know it's bad) they are giving him just making it more difficult for him to recover?

Please help - should he stay or should he come home??? It would not be long term care there maybe another week, but this is literally the only week I have to be with him 24 hours/day. I want to do this for him.with him as he has given me the world.

Any knowledge or advice is desperately needed.

Thank you!
