Summary

What Researchers Did

Researchers conducted a post-hoc analysis of a prospective study to evaluate the rate and pattern of memory surfacing during hyperbaric oxygen therapy (HBO2) in 28 veterans with combat-related PTSD.

What They Found

Among 28 participants, new memories surfaced in 10 veterans (35.7%) during HBO2 treatment, primarily in the second month around session 30.5. Prior to memory surfacing, 9 of these 10 veterans experienced prodromal symptoms like distress or anxiety, and 4 reported somatic pain, with symptoms resolving within one to ten days.

Canadian Relevance

This study has no direct Canadian connection as it was conducted outside of Canada.

Study Limitations

A limitation of this study is its post-hoc analysis design and relatively small sample size of 28 participants.
