I don't have a comment on your experience but I suggest you write up a record of your head injury and other issues and put it somewhere prominent, purse, etc. If it can be readily available for you to grab when you are sensing an episode, you can hopefully have it in your hand. My father kept a pouch around his neck with information/directions on the back side.

If it does not help you with a diagnosis, it will at least help the first responders understand what may have happened.

My best to you.
