My mother is 75 years old and in Sept 2017 had partial knee replacement. It took her a long time to come out of the anesthesia but otherwise has healed well. However, she lived with her significant other and became paranoid about him having an affair. There was no evidence. She now has kicked him out of the house and we don t know where he went. She also wants to sell everything and move closer to me and my siblings. She is about 4 hours away and has lived there for about 40 years. She has exhibited other signs of depression such as anger, sadness, not wanting to do anything. We don t believe she has been seeing the doctor regularly after her surgery. Is there anything we can do to intervene? Is this type of behavior indicative of depression, dementia or common after surgery like this? My siblings and I are not able to spend significant time with her right now nor are we in a position to have her move in with us. We have tried encouraging mental health counseling but she doesn t believe in it . Any advice would be appreciated.
