My mother has dementia and cannot remember what happened two minutes ago...she is at home with 24 hour care (4 shifts). She bruises very easy. My mother bruises and gets those purple marks on her arms. Can anyone tell me if those purple blood marks would appear on the face.. My mother now has what I would consider a black and blue mark under her eye that is suspicious but looks like the marks she gets on her arms very frequently. It's a little black and blue underneath...Any thoughts ? It was brought my attention but obviously no one is saying she fell, etc...I want to to know if it's her think skin or abuse? I just never saw the purple on her face..always her arms. Any thoughts??? Anyone familiar with those purple blood marks on seniors with very thin skin? I don't want to accuse anyone..
