Some neuros are helpful. By experience, most aren't except maybe with headache issues. They rarely have much interest in or knowledge about concussions.

A common saying is. If the neuro can't see it, test for it, or image it (CT Scan, MRI, EEG) then it likely does not exist.

So, do some local research to find a doctor that understands.

What symptoms are you wanting help with ?
That makes a big difference.

It is not uncommon for the neuro to confirm a concussion or PCS and just say to rest or that it takes time. Some have a standard protocol. No screen time, lots of rest, limited school, etc. The mix of recommendations is as varied as there are neuros.
