My husband has had multiple concussions which have led to post-concussion syndrome. After his 3rd head injury, his MDs told him he'd never work or drive again, to learn to live with extreme pain and they only had pharmaceuticals, for symptom control/relief, or a shunt that they could offer. One of his MDs, at my request, found a clinic that would do hyperbaric oxygen treatments (hbot) for conditions AMA does not officially approve of for using hbot. My husband did 40 sessions, 1 hour at pressure, in a 100% oxygen environment, and 11 days later was back at work. The results were extremely significant and all forms of brain injury can respond to hbot. We saw other folks who were coming to the clinic making progress before our eyes, kids with cerebral palsy, people who'd had strokes. The sooner after a brain trauma the treatment begins, the better, but improvement can still come years later. There are many links for many different conditions there; brain injury is not the only condition that hbot can provide healing for. The results for my husband were so significant, we now own a hyperbaric chamber instead of having bought long term health care insurance. That chamber is our long term insurance.
In addition to hbot, we've found amino acid supplementation to be helpful in symptom control. The effects are often extremely quick - a few minutes literally.
Certain amino acids are precursors to brain chemicals, for instance l-tryptophan is a precursor to serotonin, phenylalanine is a precursor to dopamine, etc. Using amino acids requires observation and interaction on the part of the healer and if possible, the patient. For instance, my husband, unable to take gabapentin, a pharmaceutical involved in GABA brain levels, found great relief using GABA amino acid, but we had to have the powdered form and initially he could only use 1 grain at a time of the powder.
Neither hbot nor amino acid supplementation has provided 100% cure for my husband by any means, but they have provided significant and noticeable healing and/or relief. I am continuing my search for other routes to healing brain injuries and will share whatever I find. I am sorry that this post is over 2 years after the initial question, but hope this will still be helpful for some people.
