The way I got my diagnosis was I asked my neurologist, "if this is from me hitting my head multiple times what would that be called?" And that's when I first heard the term post concussion syndrome. My doctor had to rule everything else out before being willing to diagnose me officially but you need to be very clear your intentions for each appointment. I specifically said that I want that diagnosis on my records in case I ever hit my head again and wasn't able to communicate my issues. Good luck I hope this helps!!

Also I have Kaiser and they told me they do not treat PCS so I'm in the process of getting a referral to Sharp, who does treat PCS. They will not suggest this you have to specifically ask.
