I think it's more then confusion- he can talk and make sense and next talk about things in his past not making sense at all. We had to put him in a nursing home with that and his heart. Heart kept him in a hospital bed, has left him not walking and nobody that can lift him. He's incontinent and he can real make a mess when he has a bowel movement. He can really get in bad moods and fuss at our family. He's running family members off. Nobody wants to be yelled at- us kids are very sensitive. Does this sound like Dementia to you?
