HBOT (HyperBaric Oxygen Therapy) is best for those with severe TBI and other more severe neurological damage. HBOT, when used shortly after the injury can be beneficial. It has not been shown to be much help for the less severe injury that comes with mTBI or concussion.

We need to keep in mind that there are two levels of recover for TBI.

Many with severe TBI are considered recovered when they get to a functional level that is similar to PCS. That is, they have lingering symptoms that are similar to those that PCS sufferers are struggling with.

Recovery from those lingering PCS like symptoms is much more difficult. Many therapies focus on learning to overcome those limitations by learning new functional skills.

Eddy, Have you tried finding a TBI Support group? The camaraderie you will find in such a group can be very beneficial. Most will be recovering from more severe TBI and living with symptoms similar to those you are experiencing. Seeing others with positive attitudes toward life can be very uplifting.

Getting anxious about that potential wonder cure is an futile exercise.

My best to you.
