Brief Summary

The purpose of this study is to evaluate how hyperbaric oxygen therapy (HBOT) may affect cognitive functioning, post-traumatic stress disorder (PTSD), depression, anxiety, and overall quality of life in veterans. 1. Does Hyperbaric Oxygen Therapy improve cognitive functioning, psychological well-being, and quality of life among veterans, as measured by pre-and post-treatment scores? 2. To what extent does Hyperbaric Oxygen Therapy improve cognitive functioning, psychological well-being, and qualify of life among veterans, after controlling for demographic characteristics.
