The neurosurgeon I got ahold of who is known for helping a TBI child with the use of Omega 3's actually recommended this to me in an email.
He said his partner the neurosurgeon for Pittsburgh (and I believe the Steelers) had been trying it out on concussion patients and is having huge success! I was a bit skeptical but he mentioned it is not weed and not does it have any of the 'drug' of maranjuna (sp?) and had been highly effective. He said it's a 'neruoprotectant'.
I have yet to try it but here is a video link from his partner.

Looks promising!!!
