Hi,
You may be interested in researching Neurofeeback for the treatment of Post Concussion Syndrom. I understand Post Concussive Syndrome can improve with the LENS Neurofeedback system. Take a look at this site:

There are other Neurofeedback and Biofeedback treatments, I suggest you Google Neurofeedback.

The LENS system seems to be unique in that the patient is only required to sit there. The LENS system helps rebalance the patients natural brain waves.

Good Luck.
