Has anyone had success with this? Im going to try this for a concussion but its being used to treat cancer, neurological problems, vascular problem, etc.
The idea is that while the core-area of the damaged brain tissue may be irreversibly damaged, there is an area surrounding this tissue that hyperbaric oxygen therapy can restore and these neurons (brain/nerve cells) can re-establish their function.

By breathing pure oxygen under higher pressure such as during hyperbaric oxygen therapy the oxygen molecules are literally forced deep in the areas of poor circulation reviving the “sleeping” nerve cells and reestablishing brain function. The success of this neuro-rehabilitation is higher in early stages after the brain injury, although good results can be achieved even years after, or so they claim.
