My dad has dementia due to liver failure and is hard of hearing as well(very hard of hearing). He also becomes easily distracted in the middle of things. For instance when a physical therapist came over, we had to turn off the TV and close the windows so my dad would not be distracted. I will be helping my dad to the bathroom and he will stop to look at a piece of lint on the couch. If I don't yell or speak sharply to get his attention-- his mind wanders completely off somewhere. Am I doing something that wrong?
