My elderly Mom who is 86 has never been diagnosed with Alzheimers or Dementia but she has demonstrated many of the character behaviors and physical traits of the diseases. She becomes horribly angry when I try to talk to her about it. I suggest that she may indeed be able to get relief from her memory loss, anxiety, and depression if she accepts help from the medical community. She stays mad at me for days afterwards. I only want what's best for her and to try to lessen or slow progress of disease. I think she may be in mid to late stages of disease that may not allow her to "see the benefits". Any suggestions as to how to proceed?
