New member here, but need a bit of advice. MiL is in early stages of dementia - not diagnosed yet but have a hosp appt arranged next week. She is currently (Friday evening) staying with us, because she is distressed that her daughter is missing, walked out of the house yesterday and hasn't been home since. She seems to be remembering an incident 35 years ago when her daughter as a teenager (now my wife - sitting here in the living room with us) walked out. She is convinced that she is outside in the cold, and can't get back into the house. All the advice we have had so far, from TV, etc is not to contradict her but to try & reassure her that the missing daughter is OK, possibly with her sister (now living away) & to distract her from the imagined problem. Tonight that's not working, she is continually agitated and continually going back to can't leaver her out in the cold, got to find her tonight or call the police... Anybody on here tonight can offer some advice please?
