63Healthy older adults
All over the age of 64, none recovering from a brain injury or being treated for dementia.
60Sessions
A structured course over approximately three months, compared with a control group.
3 monthsMeasured changes
Improvements in attention and information-processing speed, and increased blood flow in certain regions of the brain.
After a course of 60 sessions, the treatment group showed improvements in cognitive testing compared with the control group, particularly in attention and information-processing speed. Researchers also observed increased blood flow in certain regions of the brain.
What makes this research interesting is that the participants weren’t recovering from a brain injury or being treated for dementia. They were healthy older adults, and the researchers were interested in how cognitive function might respond to hyperbaric oxygen as part of normal ageing. The findings have opened up interesting avenues for further research into cognitive health, circulation and the biological processes involved in ageing.
