After a bad injury, and being mal-treated by the Brain and spine specialist at the local hospital, (16 days) I was in a steady cognitive decline for nearly 4 years. I was fortunate to receive treatment with Dr John Hughes in Basalt CO. I had done a spect scan showed the problem areas before seeing him. He got me into a 40 dive protocol at a nearby hyperbaric chamber, ketogenic diet, and an intranasal treatment. The healing and return to full cognition was incredible! I suggest a search on Joe Namath and hyperbaric, His healing, years after multiple lights out concussions was documented with scans. I really found the cost (although cheap) was well worth every penny I spent!
I hope you find yourself on the path to healing soon!
