What Researchers Did
Researchers studied whether hyperbaric oxygen treatment is safe and useful for military veterans with lasting symptoms after a mild brain injury, some of whom also had post-traumatic stress disorder.
What They Found
A case-control study compared 30 military veterans with persistent post-concussion symptoms after blast-related mild traumatic brain injury, some with post-traumatic stress disorder, to 29 matched controls using SPECT brain imaging taken before and after hyperbaric oxygen treatment. Neuropsychological and psychological testing was completed on 29 of the 30 veterans after one dropout. Side effects occurred among the 30 subjects who underwent hyperbaric oxygen treatment, including reversible middle ear barotrauma. The abstract excerpt provided does not report the study's symptom, cognitive, or imaging outcome results.

Study Limitations
This is a non-randomized case-control study limited to U.S. military veterans, one participant dropped out of testing, and the abstract excerpt provided cuts off before the study's symptom, cognitive, or imaging results are reported.
