I just want to chime in and give a reference for a treatment method for concussion related issues and specifically things like brain fog, depression, etc. that I have been undertaking for quite a while now. It has not worked 100% as of yet, but I am still in the process of figuring things out through tests, etc with my doctor.
Here a few resources if you would be interested in reading about it. If you are desperate it might be worth a shot. I cannot vouch for it 100%, but I have read all the studies and have been in contact with people who it has worked for so I really think it is legit.
AMA Certified Category 1 CME Relative Nutritional Deficiency Conference | Home Page
Management of the most far reaching and newly defined set of relative nutritional deficiencies | Alvin Stein, MD - password is 555
Parkinson's and Mucuna - http://goo.gl/JwgbO
Here is the doctor who I work withs website if you are interested. He does tele-medicine.

And again I cannot vouch for the fact that it will work since I am still undergoing with it, but if you are willing to try anything I really think it would be worth a shot. It has around 20 peer-reviewed studies supporting it.
Best wishes.
