Thanks Mark. On the NPA, I had one of those done at 9 months... 2 days of testing and a veritable barrage of psych tests. These confirmed the mTBI and identified emotional issues... a real eye-opening experience, to say the least. Just declined having a second one done recently, but am planning it for the fall.

As for the DTI, it's more a personal thing... for moving forward, it's important to me. Might sound kind of silly, I know.
