What other docs have you been to? Have you done any physical therapy?

Yes, I used to have cognitive problems and problems in crowded situations. I also even had problems having lunch with my friends/coworkers when I was still working. I would usually just be very quiet and be unable to follow the conversation. I just tried to fake my way through it. Apparently, my friends really noticed something was wrong, but didn't directly confront me about it. At the time, I was unaware that I had postconcussion syndrome. Anyway, it just took time truly resting for this these symptoms to go away. My vision issues are my only remaining symptoms. I have severe dizziness with certain movements and extreme light sensitivity. So take heart! If you treat yourself right, these symptoms can go away. I got gradually better over the course of six months of resting, though my cognitive symptoms lifted rather drastically.

I posted on the Hope and healing sticky giving some advice. Check it out if you're interested. Good luck to you. Let us know what the neuro-op says!
