My mom has early dementia. She has been living with me over a year now. When she came to live with us, her leg and forehead was all scratched up. After her being with us she is showing signs of OCD and self abuse by scratching her nose and forehead to the point of bringing blood. I have taken her to a dermatologist and there is no reason for the scratching. We have used multiple creams over the counter and prescription. I have spoken to 3 different physicians that have seen her and I can not get any help. The best I can do is cover the spots with band aids and she will still scratch those areas even with the band aids on her nose. I have shown her what she is doing and all I get is "I did that, I don't know that I am doing that." How can she know she is bring blood to wear it is a puddle on her pillow. She will scratch at night time and she disturbs my sleep because I can hear her. Background info I am a Special Education teacher and I have tried positive behavior and other ideas and nothing is working! I am always telling her to stop. I don't want to take her out in public because I don't want people to think I am abusing her or not taking care of her. I have her to wear the band aids out in public because if they are off she will get it bleeding. Yes, I keep her finger nails down to the numbs and it still does not work. I have put gloves on her at night nothing. Please help this is driving me nuts! I hope someone else has dealt with this type of behavior.
