During a recent hospital stay (for hip surgery) my mother, 85, began experiencing deep, vivid paranoia. The medical staff chose to give her Haldol, which brought quick relief. Prior to the need for the surgery, she was entering early dementia (forgetfulness, frequent repetition of recent comments and rejection of logic). I have read that Haldol should not be given to elderly people with dementia. She has continued to receive Haldol at the post-surgery rehab center. Should I be concerned about her taking Haldol?
