The website OneHitAway.org linked below has a wealth of information on methods for healing the brain and keeping it healthy. There is much useful info on how the brain functions, what happens when it is injured, and how to restore it to a healthy state. Nutrition, hyperbaric oxygen therapy, and chiropractic neurology are explained in understandable detail. There are videos also. The website and foundation of the same name were started by Darren and Jill Cde Baca, whose son Brett sustained 2 concussions and struggled with symptoms for more than 6 months before being healed (search for his story on this website under Brett Cde Baca).
