Thank you all for the replies. We have put mother on Wellbutrin which she took about 6 years ago to quit smoking. She is better. I think some of her confusion was the pain meds. She is not taking any pain meds now. I can't say that her attitude is better. She is still agitated and uncooperative. It will take some time for the antidepressant to kick in.
I wish the memory problems were less but they aren't. Her short term memory is very bad. Plus she is quite upset about how my sister has been handling her finances but it is because she was so out of it when the bills were coming due and now she can't retain the memories.
We have taken her to a geriatric specialist.. He wants to focus on the physical things first. I'm not sure he can do anything about the memory. I suppose time will only tell.
Pain medication can make one less lucid, depressed, and at times paranoid and confused.
Perhaps a doc can review her medication. Was she on meds before this happened and have they been continued? The hospital/nursing home enviornment can also contribute to the state she is in. I know I went thru the same things.
It sounds like depression, both from the loss of her mother and the loss of independence from falling. She probably suddenly realized that she's getting older.
My dad (67) was in an auto-accident back in March, which he's still recovering from, and he also lost his two brothers in the past two years, so he's going through the same thing and gets depressed and defensive sometimes.
Some aspects of it sound like dementia so she should be evaluated by a neurologist. They could also find out if when she fell there was an impact on her head and she had a TBI (generally they would rule this out). They could also determine if a further referral to a psychiatrist is needed as she could be experiencing depression as well. Any doctor who is a gerontologist should have a fuller understanding of these issues. It would be essential to determine if they are administering any medication to her now as sometimes in nursing homes antipsychotics are given to calm people down which is an inappropriate use. Also it would be worthwhile to find out if she would be eligible for a home attendant as living in the community is better for a person in general including their health. Also you or another family member should see what the conditions are like there when visitors are not around for her safety.
