Also, with concussions is it uncommon to not remember clearly the hour or two before? I remember things, vaguely; it's all hazy but I have like 50 minutes of time that is completely unaccounted for. I think I got lost while driving and I've been able to kind of reverse engineer everything so I know what I was doing leading up to the accident, but I don't actually remember it. I know I missed my turn onto the road I was going to get on so I was taking another route....and now that I know where the accident was I know the route I was taking to get back on course. I just don't remember that thought process at all.
