The neuro-psych assessment with define what your current condition is. It will at least give you a baseline to work with.

Other than being an exhausting day, it is not a big deal.

When I said your mom is over-doing it, I meant two things.

One, the neuro-psych assessment will not make a big difference if it is this week or next.

Two, the Mayo Clinic is not a specialist in PCS by what I see. They actually dismiss a single concussion as a cause of long term problems. You can find this information on their web site.

For some reason, they hold to the idea that if there is no Loss of Consciousness and no Post Traumatic Amnesia beyond the first few minutes, the patient will usually recover fully, given time.

I was shocked to read such ideas on The Mayo's site.

"Concussions are common, particularly if you play a contact sport such as football. But every concussion, no matter how mild, injures your brain. This injury needs time and rest to heal properly. Luckily, most concussions are mild and people usually recover fully." from http://www.mayoclinic.com/health/concussion/DS00320

In my experience, the "specialists" at the renowned hospitals get bored by garden variety concussions. It is more valuable to find a specialist who is doing ongoing research into concussions. They are more likely to take a garden variety concussion with persistent symptoms more seriously.
