My older brother (36 yrs old) and I (25 yrs old) are the primary caregivers to our two elderly grandparents with dementia. My grandmother is still able to do ADLs with assistance; however my grandfather is completely dependent on us. He is on a pureed food/thickened liquid diet (due to being hospitalized for aspiration pneumonia a few months ago); has debilitating back pain due to a mild compression fracture in his spine (receives steroid shots for this) and cannot walk or get up on his own. My brother gets very impatient with the level of grampa's care; for example, I ask him to help me get grampa up to the bathroom in the morning -- he comes storming in -- yanks him off the bed and drags him to the bathroom cursing up a storm while grampa is yelping in pain. He just sits grampa in his chair all day long without changing his position; and at night also does not change his position or underwear. Grampa is completely soaked in the morning. As a result, he now has a stage 2 ulcer (size of a pea) on the inner part of his right buttock (we are addressing this issue now with the home care nurse and DR) . I have gotten on to him about re-positioning and changing his underwear but he is lazy and would rather play video games all day. This stresses me out as I work full time (peds private duty) and go to school and I take care of grampa on my days off. I tried talking to my Mom about it (she is POA) but she is oblivious to the level of care grampa needs and just writes it off. We do have OT, PT, ST, home health aide and nurse come in weekly but it is only for 30 mins at a time. Grampa is not getting the care or respect he deserves here because of my brother; any advice on how to handle?
