I know you wrote your post well over a year ago now, Dawn, but I just want to say how encouraging to me it has been to read of someone who has had a similar memory experience to mine.
It is devastating to have such huge holes in past memories that have completely disappeared and no one really understands, do they?
However, I am now on a drug which controls my seizures and I have ‘relearnt’ some of the skills, such as using the sewing machine, and even remembering how to use recipes that I knew well in the past, e.g. making marmalade. I had to start learning all over again each time. Very frustrating. However, this year I could remember enough of what I did last year to do OK with the marmalade. I also write more notes in the recipe book (and hope I’ll remember where to find them!). And I think the brain has found a route to some of those older memories now, somehow. So I really hope the same has been true for you and that you are doing better now than when you wrote this.
I still have a real problem with visual memory e.g. people – remembering I’ve met them before, or anything they’ve told me about themselves, however important. Forgetting their name is the least of my worries as lots of people do that!
