My brother and his family just visited from out of state and I think it really wore her out mentally. They visited off and on for 5 days. They didn't call ahead. We had a few hours warning when they were already in town. She's been more confused and mad since the visit. They left 2 days ago.
Consider she might have a UTI and have her tested.
Is she on any meds for agitation? If she isn’t I would ask her doctor to prescribe something for her to calm down.
So sorry that you are having these issues. Wishing you peace.
If she is well, then it will be some days before you know if this is permanent or not. Given the circumstances and the suddenness I suspect she will be back to her normal level, but do know that this IS the future and you may be looking at a time when LTC needs to be considered.
Hope you will update us.
If small children are there, remove them if they seem to upset her. My grandson was 3 when Mom entered an AL. She and the residents loved seeing him. But he was a go go child so I did not stay long.
