I’ve been noticing it it with my husband who was dx with autoimmune aplastic anemia. He has had ATG, and blood and platelets every week since May and nothing is working. He was on Cyclosporine , but that hard on his kidneys. He is now on Tacrolimis and high dose steroids and that’s when I started to notice the hearing issues and occasional not comprehending what I was saying to him. He keeps calling oir dogs and his friends by the wrong name.
