My mother has been in SNF since Jan, 2013 after a heart attack and fall that broke a rib, and in hospice care since Feb, 2013. Her decline has been slow but steady during this time. She has steadily lost weight from around 105 lbs to approx 80 lbs (nursing home no longer weighs her) at my best guess. The weight loss is due to her sporadic appetite and advanced dementia/Alzheimer's. There have been at least 2 prior occasions when nurses, hospice and family have thought she was nearing the end of her life. She has rallied, gained a little weight, and been more alert for a short time after both occurrences. All of us involved with her care, can't get over her resilience - most people of her age, medical history and genetic background would have passed years ago. She is, once again, in a decline-and this one seems to be worse than any before. She no longer responds and any sounds she makes are unintelligible. She has been on 5mg Roxanol 3 times in 24 hrs, sleeps most of the time, and refuses most food & water. In the past three days, when she is successfully awakened, I have observed her vigorously biting her sheets, a small hand cushion (to keep her nails from puncturing her palm), and a hospice volunteer's unzipped hoodie. It was difficult to get the hoodie material which included zipper out of her mouth. I am concerned if someone gets too close she may bite skin since she has bitten people twice in the last four years. Has anyone else experienced this type of behavior?
