I'll confirm what Mark says about Neuros... if they don't have an objective measure demonstrating an abnormality, they won't offer much other then confirming an mTBI occurred.

I actually had one Neuro state things plainly. If you have a depression and/or anxiety comorbidity, the Neuro will always conclude that these comorbidities are the reason for ongoing PCS issues. The only time a Neuro will change his/her opinion is if a Psychiatrist concludes that all comorbidities (i.e. depression) are resolved. If this occurs, time elapses, and other PCS issue remains, the Neuro will then conclude that there must be a neurological etiology.

Seems silly to me, but he was pretty blunt about it.
