Is this trial a fit for you?
✓Likely a good fit
Ideal participants are veterans aged 18 or older who completed the prior HBOT protocol (40 sessions) and can provide informed consent for the follow-up study.
✕Probably not a fit
Patients who did not experience initial improvements or who have unstable medical or cognitive conditions may see little to no long-term benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This interventional Phase 2 study enrolls veterans who completed a full HBOT protocol to see if the cognitive and mental health gains last beyond treatment and whether delayed improvements appear months later. Participants will undergo follow-up assessments 12 weeks after finishing HBOT to evaluate durability of outcomes related to cognition, PTSD, anxiety, depression, and daily functioning. The study aims to clarify the long-term trajectory of HBOT effects and inform future treatment recommendations.
Why it matters
Potential benefit: If successful, it could confirm lasting benefits of HBOT for cognitive function and mental health in this population.
How similar studies have gone: Prior studies suggest potential short-term gains from HBOT; evidence of durable long-term effects remains limited and this study addresses that gap.
