Hello everyone,
I haven't been on here for a while as I very fortunately got my life back after a 2 year recovery period.
Anyhow, thought I'd share this with the community:

Ben Greenfield has a great health and fitness oriented podcast which I recommend per se.
Here are two very relevant episodes.
Also various useful links are contained in the show notes for each.

The Best Concussion and Head Injury Remedies

The Concussion Repair Manual: A Practical Guide to Recovering from Traumatic Brain Injuries

Plus you might want to check out this book on Amazon:
"Concussion Repair Manual"
The Concussion Repair Manual: A Practical Guide to Recovering from Traumatic Brain Injuries: Dr. Dan Engle: 9781946697349: Amazon.com: Books

All the best to you
