It has long been known that vascular improvement was gained from HBOT. This is the first time that cognitive improvement has been noted. The cognitive improvement is slight at only 8 to 13% but it is improvement none the less.

It would be interesting if they showed the test cohort cognitive scales compared to the uninjured population. Did the cognitive improvements lift the subject's function in relation to the general population? My memory and processing speed scales in the bottom 10% of the population. Would it be improved to the bottom 11-12% of the population? Would somebody whose functions were at the 50% level be improved to the 56% level. There is a lot of information missing. Improvement based on population scales relates to ability to function in society.
