I have horrible memory problems but they are not related directly to any episodes. I also have PTSD and spent a lot of my childhood in a state of dissociation. But my memory got noticeably worse after the BP was diagnosed, related? I don't know. I'm not on anything right now except thyroid meds.
I have a place I hang my keys, a pill box, and tons of cute note paper and stickys around so I can write down anything I might need to remember, but....then the problem is where did I put that important note with the date and time??? They always seem to end up inside of a book.
