My dad, who I’ve posted about before on here, has been in a nursing home for a fortnight, having spent the previous month in hospital. He was delirious in hospital but improved gradually. Since going into the home we’ve noticed a steady deterioration again in his mental state. He’s become fixated on disasters - so every time we visit there’s been a fire, a flood or other catastrophe. Today he told my sister a murderer was poisoning patients. He is very polite to the staff but complains behind their backs that he’s being ignored. I don’t know if this is a reaction to the new environment ( he really didn’t want to go into a home) and will settle or whether it’s a sign of rapidly advancing dementia. Any advice or shared experience would be very welcome.
