They aren't seeing or hearing things that are not there. My cousin will make an hour story out of a trip to the grocery store that happened 20 years ago. Nobody will stay in the same room with him because of it. If we are all watching TV and he didn't pick the show, then he will talk non stop. If you say "Shh, I am watching this, he ignores you and keeps on talking." Is that early dementia? I am trying to figure out where he stands health wise. By that I mean, how much longer can I expect him to live. Not that I want him to die. But, I am on disability, my husband is also older and due to some other issues I feel as though I am taking care of everyone and I am exhausted. So, I need to know what is ahead so I can plan. He has COPD, kidney failure ( possibly stage 3b). He has a strong heart but did have blood clots in his leg several months ago. But I notice that his kidneys seem to be getting worse. His urine is so strong, you can smell him when he uses the restroom, two rooms away. He wets himself but won't wear a Depends. He has finally agreed to use a shower chair. In the past 4 years he has gone from being able to walk, then walking with a cane, and now uses a walker in the house. He nods off during the day frequently. He used to go out every day,now it is every other day. But, he still drives, which is why I can't get any personal care help for him. He has developed high blood sugar recently but this is the first for that. Something called Renin (kidneys) is extremely high, 52, when the average is .3-6. The doctor said not to worry about it. The doctor has told him no more red meat. Liver, thyroid are normal. I am confused and concerned. I have to go out of town for a few days and am afraid to leave him alone because I don't know where he is at healthwise, in terms of how fast he is likely to decline. In fact I have several trips planned and am quite worried.
