It appears in the bum and shoulder area. She is cognitive and linguistic deficient due to her frontal-temporal dementia. Her cognitive score is 0 which means she totally does not understand any instructions from us. She only sleeps 10 hours a day. We move her sleeping position twice during that 10 hours. We already have her sitting on donut cushions, raised her leg to improve blood circulation, and sleeping on cushion support in the back and in the leg area. The doctor only prescribed medicated cream to apply to the wounded area. I want to find out any precautionary measures I can take to minimize the problem.
