My mom has Dementia, and within the las 5 weeks she has changed. She does this fake crying like a child, there are never any tears. She cries anywhere between a few minutes to 5 minutes then she will completely stop, talk normal or ask a question and then start again 10-15 minutes later. This is going on all day long unless she goes to sleep at night. She wakes up every morning at 3 am and does it all over again. Has any ine ever dealt this this? I have left the room and she stops, but when I come back it starts back up again. Oh and her reasons for crying do not make sense and generally are made up.
