All participants in this study were diagnosed with persistent post-concussion syndrome related to mild traumatic brain injury. A randomized group received a full course of 40 hyperbaric treatments at 1.5 ATA, daily for 60 minutes, 5 consecutive days per week, for a total of 8 weeks (2-month long hyperbaric intervention).

The hyperbaric subjects experienced significant improvements in memory, anxiety, sleep, PTSD symptoms, and quality of life.

More importantly, After crossing over to HBOT the Control Group experienced near-identical significant improvements. Further improvements were experienced by both groups after completion of their last hyperbaric session, during the 2-month follow-up period.<view study>
