Your post is a little vague. For what symptoms are you seeking relief?

If you are referring to services from Brain State Technologies I talked to them at a TBI conference a couple of years ago. While they seemed sincere, the premise of the hemispheres of the brain being "out of balance" seems a little simplistic, and they were vague on how "balance" is restored.

What are you seeking to accomplish in your recovery? What has been your recovery plan to date? I'd examine these questions prior to a leap into some untested treatment program.
