Looking today in forums and Google about strangers visiting with people in the early stages of Alzheimer’s disease. It seems to be a mixed bag of good visits and not so good. Lots of normal visits and lots of visit with surprises. Agitation seems to come easy for some patients. Some do not seem bothered. Others act okay with a visit one day and on another day become extremely agitated.
I have witnessed both in the past.
It seemed to be a consensus, that you should let the visitors know about the possibilities and the uncertainties.
