My spouse is a 87 year old man that had a stroke nine years ago. Recently his mobility has gotten much worse. He cannot dress himself, bathe himself and can barely walk using his walker. A year ago he didn't use a walker. Over the past several months he has started waking up in the middle of the night to ask questions. Some of the more memorable ones go like this, "Mary, Mary....I don't think I am breathing." Me..."are you alive? " "yes." Are you gasping for air?" "No." "then I think you are breathing." "Okay." ...Sometimes he insists I get up and check that the clocks are correct as he is sure its much later than 3 AM. No, its 3 AM. I am exhausted all the time now, which puts me in a pretty bad mood. He goes to bed at 8 and gets up at 4. He might wake up three or four times a night. I haven't talked to his doctor about this yet. I've just started seeing things that resemble dementia very recently, like creating a scene at the doctors office etc. Any ideas?
