Hyperbaric oxygen therapy has also been used experimentally in the treatment of PTSD and TBI in military personnel. Some patients have shown remarkable improvement in their condition.

It is valuable for treating many problems such as carbon monoxide poisoning and certain types of wound care, but it can also be dangerous to your lungs especially. I am highly skeptical about its use for treating psychological conditions and aging.
