I feel a bit stupid to ask this question, but here it is. Sorry for the mistakes, but my language is French. My name is David, and I am an academician of 42 years old. I am in perfect health, and an athlete. On average, since I am a child, about once every three years I faint (8 times in the last 22 years). It is emotional at its source, because it ALWAYS starts with something that I have seen on t. v., read in a book, or that I am simply thinking about, or that people around me talk about. In most cases, the theme that makes me faint is medical in nature - for example, needles or blood. Most of the time, I can manage to prevent the fainting by thinking rapidly about something else, but sometimes, rarely, the process is too fast and results in a fainting. I simply lie on the ground and let myself pass out; I always see it coming, and only once did I not have time to lie down, but I was already on my knees. People that have witnessed such episodes have reported that it lasts only a brief moment, and then I regain consciousness. Again, it is strictly emotional, because, let say it is something seen on t. v., if I would not have looked at that channel at that particular moment, nothing would have happened. It is part of my sensitive personality, and I know it will happen again. My question is this: Can I loose academic content already acquired from such an episode, from the fainting itself? Can I forget it? Can I loose information, like retrograde memory loss? Thanks, David.
