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, daly 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> Read Less

Alterations in social behavior, including but not limited to anxiety, are prominent features of Fragile X syndrome (FXS). The findings of this study indicate that hyperbaric oxygen therapy “resulted in altered anxiety and social behavior in mice (showing increased levels of social interaction and decreased "social anxiety”) and could possibly be used as a treatment for FXS” <view study> Read Less

With the increase in pharmaceutical prescriptions for anxiety, this study may provide a safer and more natural option for those suffering from from this condition. In this study, a single application of hyprebaric oxygen therapy was shown to have an anxiolytic effect in mice. Typical HBOT programs involve the use of multiple sequential visits, in short duration. It would be therefore interesting to see if the conditioning of the brain through hyperbaric oxygen therapy can have a long-lasting effect on anxiety. Until further studies, we will not know, but what we do know is that there is an effect in the brain, probably mediated through the release of nitric oxide <view study> Read Less
