The closest match I could find to this was anxiety because my memory loss triggers it.
I do not know if this even has a name but I literally forget what I am doing in the middle of doing it.
For example this morning I focused on remembering 1 thing. Just one.
And I forgot. I get to the office, remember, sit down to write down a reminder and in the time (about 2 seconds) it takes the word processor to start up, forget again. I start writing down everything I did in an effort re-trigger the memory, remember again, start writing down what it was, and forget right after I type "Reminder: "
So now I'm wondering what very very important time-critical thing I have not done. I'm not thinking it's leaving the stove on while going on vacation for several days (which I've done) or renewing my registration and then not sending it in (which I did last week) or forgetting to take my heart medication (which I do all the time).
I regularly practice games like Sudoku to keep my mind going. I read a lot, exercise and have an excellent diet. But my brain refuses to work.
This kind of ongoing mental failure drives me crazy (like road-rage crazy). And I wonder what disaster I am creating for myself or others because my brain still won't remember that 1 thing.
