After some effort, I managed to get DH into the car today (can't get a little one; he uses a walker) and we went to the farm stand and the market. He stays in the car. I remove the keys, otherwise he locks himself in. But he was in a good mood. and when I got back in the car, he said, he just remembered a quote from George Bernard Shaw - when Caesar says (about the burning of the library in Alexandria, which he named) "He who has never hoped can never despair." I said, is that you? (I meant, You don't despair of your condition because you never hoped for better?) And he said, well, maybe a little. (the quote and the context were dead accurate.) HOPE
I mentioned, as we were driving, the discussion we've been having about CPR causing or facilitating dementia. I went in the market. When I came out, he told me a long involved and totally false tale about students congratulating us when we got married, and said there was someone there who was coughing and choking over at the side from having taken too much CPR. DESPAIR!
I realize now that I was dealing with confabulation in the years between the bypass operation and my husband's accident. One of the signs that something was going on for more than the 4 years I've been aware of.
