My husband is so frustrating to speak to, sometimes. He does not remember some of what I tell him. An example is, even though he was present when the doctor told him he would be in the hospital until at least Thursday he insisted that it never was said. Or, we will have a circular conversation about reasons he needs to do something or make an appointment. He is easily frustrated and angry. I have found (and I am in really early stages of this) that just repeating the information for him is less frustrating. If he is angry/frustrated, I leave the room and do not try to engage in settling him down. Usually it is something about the computer not doing what he wants it to. I am trying to be more scheduled with meals and events. He does know that he is slowing down mentally, but I adjust to whatever it is rather than pointing it out.
