I'd love to see a study or report of individuals who have went through 40 sessions of 60 minutes at 1.5 ATA over 8 weeks who have NOT experienced improvements or have experienced minimal improvement. I'm curious how little one can expect to get out of that treatment. If such as study showed that 95% of TBI patients 1+ year out experience significant improvement, I think that helps people feel comfortable committing the time and money.

I haven't heard of someone going through 40 treatments and not experiencing improvement they were happy with.
