Can Hyperbaric Oxygen Repair the Damaged Brain?

I would trust this piece from Dana before the puff piece from HBOT pushers(Efrati). Your doctor can decipher the competing claims.

While many agree that Efrati’s data are promising, a prior study run by the U.S. Air Force found no significant differences between hyperbaric oxygen treatment and a sham treatment on patients with mild traumatic brain injury (TBI). Both groups showed significant improvement over the course of the trial. Those results were published in the November 2012 issue of the Journal of Neurotrauma.
