Well, when I spoke on the phone with Dr. Paul Harch, who is one of the leading researchers in the world on the use of HBOT for concussions, he said it's normal for most people to know after the first few sessions whether HBOT is going to help them. If you do a google search on him, you'll see that Harch has written a book on HBOT and is receiving a government grant to study and use HBOT to treat combat veterans. Dr. Harch said that people normally pursue about 25-40 sessions over the course of a treatment, but that every person is different and the whole process should be overseen by a doctor and constantly monitored to find the right ATM pressure for the chamber.

Ultimately, I decided not to go down to New Orleans to do HBOT with Dr. Harch because I found out that I have Lyme disease and could be treated locally by a Lyme specialist. Thus, my experience should be discounted from a concussion standpoint, as I am 100% convinced that my primary health problem is Lyme disease.

There is actually more research out there showing that HBOT is beneficial for Lyme treatment than for PCS, but I won't go into that now because this is a concussion forum, and I am headed off to HBOT! If anyone has questions about HBOT generally, I am happy to answer later.
