Key Takeaway
HBOT improved cognitive function and increased cerebral blood flow in healthy adults over 64, suggesting oxygen therapy benefits brain aging.
Summary
This randomized controlled trial examined the effects of hyperbaric oxygen therapy on cognitive function in healthy aging adults.
Key findings:
- 63 healthy adults aged 64+ completed the study
- 60 HBOT sessions over 3 months
- Significant improvements in attention, information processing, and executive function
- Increased cerebral blood flow on imaging
Results:
- Memory improvement: Significant gains in multiple domains
- Processing speed: Enhanced information processing
- Brain imaging: Increased blood flow to cognitive regions
Protocol:
- 60 sessions, 5 days/week for 12 weeks
- 100% oxygen at 2 ATA
- 90 minutes per session
Clinical significance:
While this is HBOT (hyperbaric), it supports the concept that enhanced oxygen delivery benefits brain function, providing mechanistic support for EWOT approaches.
