Poor Sleep Prevents Brain From Storing Memories

I like to follow these types of stories. I lost all of my memory one morning when I was 19. The cause isn't clear. I was in an underdeveloped country at the time, so the medical facilities didn't exist to determine what had happened. (It might have been a delayed effect of a car accident I was in two years earlier.) It's also probably important to note that my ability to form new memories was also severely impeded.

I wonder a little bit about what "moving" a memory means. At least in my amateur study, memories aren't complete entities (like a file, database, etc). They are mixes of memories, the awareness of what has occurred, and associations, our integration of what we already know with what we are remembering. That's part of the reason people can have such differing memories of a shared experience. Some of that is about how memories are retrieved. In my study and experience, they are retrieved by these associations we make. That's why memory tricks involve making varied associations -- to song, to a mental or physical image, etc. For people who haven't learned those tricks, an association can be as simple as "I remember we met in a bar..." then the rest of the picture is pieced together.

I wonder sometimes if my having to learn different ways of "remembering" things will allow me to maintain a higher level of memory functioning into my elder years. I have to be very aware and purposeful about what I remember. I was in college when I lost my memory, so I had to learn very quickly how to perform in school without being able to learn in the conventional sense (I could not remember the beginning of a semester by the time it ended). So I focused much more on the integration of memories into my existing awareness (aka forming associations between new experiences and prior knowledge.) I still have a very poor memory retrieval in the classic sense, but I can still learn lessons well. It has just required a much higher level of sentience with regards to how memories are stored and what I hope to gain from a memory in the long term.
